Hi guys,
I am new to this forum - don't have my GTD yet but told start of Oct (initially it was mid July!!)
Had the same hassle with the dealer most of you seem to have had. Not impressed but decided to ride it out.
Anyway - now that some GTDs are actually being delivered I was wondering what the real life MPG figures on it are like.
I decided on the GTD to get rid of my S3 which is terrible on the fuel and with VW boasting some very impressive figures for the GTD I thought it would be a serious machine.
However, reading a bit online about the new Mk7 diesels in general they appear to be returning nothing like the claim stated by VW and causing me a bit of concern.
I understand you will never get what the book says but just wondering what people are getting cruising the motorways at 75mph with cruise on.

Welcome Mike,
If this is GTD only maybe use the TDI section?

Was the adaptive cruise on not one of the reasons why people think it has failed to reach its desired MPG? i.e. cars coming in on front of the Golf so making that having to alter its speed quite a lot? Just a thought!
Also I've found I can achieve a lot more MPG with cruise off simply by reading the road ahead. Things like going downhill I can feel the car slowing itself down to keep to the desired speed.
-
Yeah - I agree regarding cruise but I regularly do a stretch of road that I can sit at 70mph on and not have to slow down for much. Hopefully the adaptive part of the cruise can be turned off and just used at constant speed.
If I can get 50mpg on the motorway out the GTD I'd be satisfied, 60mpg I'd be over the moon - anything less than that I'll be pretty annoyed..
Will be interesting to see.

I got 50mpg on a GTD DSG (extended test drive of demo) doing a 62 mile round trip with about 12 miles around the doors and 50 miles of it sitting at 80mph on dual carriageway. The car had less than 900 miles on the clock (so some running in gains yet to be realised) and the DSG will hit you for 10% on your mpg vs manual so expect at least 55mpg with the manual. I had ADC switched off and no aircon on that trip, ambient temp about 20C. About 8 times on the trip cars overtaking lorries slowed progress down to 60mph, but as soon as they were out of the way I buried the accelerator until I hit 80mph again and stayed there. I think it will meet your expectations. I didn't have cruise on - not sure how much fuel penalty you will incur for that - maybe a fair bit if you try to drive closer to the car in front than ADC would like and it is braking for you regularly.

DSG will hit you for 10% on your mpg vs manual
Official figures say 6% difference.

Mate, I opted for C/C on my Mk GiT but wished I hadn't. For me, C/C is not fuel-efficient..........and I have tested this many times over the past 3 years. I get better efficiency in manual mode, so in my opinion disregard any brochure details for fuel under C/C etc !
Hope this helps

Depends how many doors: GTD 60.1mpg vs 67.3mpg (5 door comparison) DSG does 90.5% of manual (combined), 3 door comparison is a bit closer (93.3%) because 5 door manual does not appear to have the fuel penalty vs 3 door that DSG has. :huh:
-
I guess I'm talking GTI figures in a GTD thread again. My bad.

GTI figs (3 or 5 door) come in almost the same as 3 door GTD comparison - 93.6%.
Why is the 5 door DSG GTD such an anomaly? Weight of 5 doors (30kg) and DSG (17kg) combined take it over some threshold that requires it to be geared lower to maintain same performance as 3 door? :huh:
-
Figures I've seen are 47.1 vs 44.1, which is a 6% reduction. No idea if its 3 or 5 door, was just a review. I doubt it makes much difference otherwise we'd be talking 20% losses in mpg just from sitting another adult in the car. Most adults weigh more than 47kg.

Those are the GTI figs, with no 3 door/5 door penalty in either manual or auto, unlike the GTD.

Someone suggested using the crz control without utilising the active part. . if anyone can suggest how to do that (apart from putting a bin-liner over the radar) I would be glad to know, as , in moderate traffic, it is constantly on the brakes ,as it has no ability to anticipate.
The "eco" part of DSG (where engine revs drop to idle and you just coast) is also lost when using crz control in active (don't know about non-active crz control) as I guess the car will brake if you exceed the set speed rather than just coast.
-
Not a GTD I know, but using the adaptive cruise I managed to get 69.7mpg out of the 1.6 TDI bluemotion technologies hire car with 5500 miles on the clock and that was in heavy traffic on the motorway too so the adaptive cruise was working overtime.
-
Anyone got any real life figures for the DSG?

Anyone got any real life figures for the DSG?
Aye, my dad (GTD DSG, about 3500 miles on the clock) is getting about 46mpg on motorway miles (he likes to be pushing 85-90 when he doesn't stand out doing it), and about 54mpg on his commute to work which is 15 miles on 60mph single carriageway strictly doing 60mph because there are almost no opportunities to overtake and plenty of speed cameras about. His old MK5 Golf 170TDI GT (tuning box up to 200PS) gave better mpg, but the difference is in the box.

Sounds alright :) Beats my current mpg of 35mpg
-
My current mpg for my first 135 miles in my manual GTD is as follows:-
First trip home from the garage and my first trip to work (7-20 miles) = 49mpg
The next few commutes with a little town traffic (20-65 miles) = 45mpg
Few more commutes with the car attempting DPF regen (65 - 105 miles) = 43mpg
Trip to the Metrocentre to use up the last of the delivery fuel (105-117 miles) = 40mpg
Trip from the Metrocentre with V-power Diesel fill up (117-130 miles) = 49mpg
Mpg so far is dissapointing to say the least. I could cane my Scirocco 170TDI and still get about 50mpg on my commute and probably 53mpg on the Metrocentre visit, without using V-power, in the summer.
I had 1 experimentation with V-power on my Scirocco and ended up with 5% more mpg, which didn't quite cover the premium, but a fair few VAG TDI users claim it knocks the number of DPF regens in half and gives around 5% gains. Right now V-power diesel (and petrol) is on triple points until the end of Sept, essentially 3p per litre off.
Hopefully the new gen engine is going through some learning curve that none of my previous TDIs have gone through to get better economy in the longer term. Some MK7 150TDI GT users have seen significant mpg gains over the first 4k miles, of around 10%.
-
Starting to see a pattern here. My old Scirocco got to 40mpg very easily on any journey (less than 4 miles) and then crept steadily to 50mpg without trying too hard, between 4 and 10 miles, and if I didn't hoof it, it crept up steadily to maybe 55mpg over the next 20 miles.
In my new GTD it seems to get to 35mpg very easily and quickly, creep up to 40mpg and then have tiny incremental gains up to 45mpg over another 10 miles. I got it up to 46mpg on a 35 mile round trip. I was up at about 44mpg when I hit a flat/slightly downhill stretch of the A1 on the way to the Metrocentre - this is usually where my mpg creeps up to 55mpg, but it stayed pretty steady at around 45-46mpg.Maintaining 75mph in this car on the flat seems a 45mpg operation, but a 55mpg operation in the Scirocco. :undecided:
-
hopefully its just because its a new engine MH.
Can you remember what your MPG was like in the Scirocco when you first got that?
-
Starting to get me worried now. The high mpg was one of the main attractions for me. Right now my 10 year old 1.4L Civic does 45-50mpg on average and it's a bleedin Petrol lol.
-

Can you remember what your MPG was like in the Scirocco when you first got that?
Yes, 48-50mpg straight from new. MPG didn't improve much, but power did (maybe I drove it a bit harder when the power improved and negated any fuel savings, but it was considerably better then my GTD right now.
-
Hmm you're worrying me now. Only went for the GTD over the GTI for the mpg. Hope it does improve. Does the scirocco have a DPF?
-
If you're getting 20mpg less than stated even when driving carefully I'd be tempted to call that serious grounds for a miss sale. It could cost you thousands in the long term.

Wasn't expecting a DPF regen at just 65 mile on the clock either. Wondering if I have a leaky injector. I will register my early concern and see how it goes over the first 500 miles before getting the dealer to investigate.
I'm driving it gentler than the Scirocco (but not babying it), so i'm pretty sure driving style isn't to blame
-
Hmm you're worrying me now. Only went for the GTD over the GTI for the mpg. Hope it does improve. Does the scirocco have a DPF?
Yes, Scirocco 170TDI has a DPF and absolutely no eco tech (stop start, brake regen etc) at all. I expected the GTD to match the Scirocco straight away on fuel economy and over time (maybe 5000 miles in) exceed it by 10%. Right now it is 15% under the Scirocco's. I've got to get from 44mpg to 60mpg (36% improvement) on my commute to meet expectations. I do think the car is tighter than the Scirocco was - it is really down on torque/power in 5th and 6th gear acceleration (but surprisingly livelier than the Scirocco lower down) - or maybe those gears are a bit taller than before. I will have to check what the engine is doing - the Scirocco was at 2200rpm at 80mph in 6th.
I’m hoping with extremely premature first DPF regen and poor mpg that the first few hundred miles are expected to be poor because all of the systems are running self-diagnostics, trying stuff out to find their optimum settings, and using more than usual fuel to do it. Perhaps with a more sophisticated set-up, there is more "learning" for to do. If that is the case then great – maybe VW should let us all know in the handbook to be aware that the first few hundred miles that the car is going to be running noticeably less than normal.
If VW introduce ACT/cylinder shutdown tech on the GTI engine in the future, this could be the last TDI that I buy.
-
Agree with that MH. My wife's new Polo Blue GT with the 1.4 ACT engine is currently delivering between 52-55mph, (and that's with the wife driving - who doesn't hang about). Took it to Cheshire Oaks retail park last week (circa 60 miles round trip) and it average an incredible 64.2mpg - that's from a 140ps Petrol !
So like you, if the next generation GTI's get this tech and can therefore get high 40's low 50's then it will be the last diesel I'll own as well !

What are you getting at the moment sootchucker? Or have you not had the chance to drive it what with all the product and paint application? :whistle:
If I remember rightly your 140 Scirocco was a bit thirstier than mine, so maybe you’ll be pleasantly surprised with yours. Maybe if you’re getting decent mpg already and no early DPF regens then it might confirm I have something wrong with mine like a leaky injector. My experiences kind of tally with my dad’s early days though. He had a long run home in it (Newcastle to Southampton) and managed 47mpg ave maintaining about 80mph (my Scirocco would have been pushing 60mpg). His though has been improving recently!
-
Not had the opportunity to properly drive it until tomorrow bud (only got 17 miles on it at the moment :grin:)

Like that comment, but time well spent on the drive, looking good and love the painted calipers. GTD do have red on sport sound upgrade so not that unusual and be tempted to do myself.
But on to economy and as my arrival date comes close being paying more attention to performance of own as a comparison and on my 2 regular journeys of 125 and 225 roundtrips on A and Motorways I get between 48-52 MPG. (I do have stop start but it is rarely activated)
Given have DSG and fact that the quoted figures were likely optimistic my expectation was 50-55 MPG for same jouneys - Given regularity of my journey I should be able to give a pretty good comparison.
Mine did improve too, it was well over a 1000 miles before this now stable figure on an extended run became the normal.

Hi Guys,
New to this forum, and may be new to VW entirely....
Went for a spin in a new GTD manual today at Loughton with a view to a new 3 door carbon grey with sunroof and leather to add to a standard one. Liked the package as a whole.
Seen some of the previous posts, I do about 300-400 miles motorway, and about 40 miles town driving per week.
What do you think my real world fuel costs would be per week on a manual GTD based on the economy any current owners are experiencing?
-
I had slightly better mpg in eco mode today as opposed to sport. You might be thinking "duh!", but in the individual components of the driving settings within eco/normal/sport that you can customise in "individual", I thought that the "engine" setting was just for the sound actuator and not altering fuel usage in any way (as seemed to be the case with my Scirocco). Whilst sitting in Eco and halfway home I was getting a semi respectable 48mpg. I put it in sport for a mile and even though I was just maintaining the speed I had got up to and maintained in eco, my mpg started to dip quite quickly until I switched it back to Eco where it started to recover.
As ridiculous as it sounds, it seemed like the car was using more fuel in sport, compared to eco when doing the exact same thing (sitting on dual carriageway maintaining 75mph). Even pushing the accelerator harder in eco to better the moderate acceleration seen with less accelerator in Sport, fuel usage was less.
-
Hmmmm. Seems like the claims aren't anywhere near what one would expect.
What about mapping? Would that improve the economy on constant throttle??
-

My dad had a chip box from TDI-tuning.co.uk that took his MK5 Golf 170TDI to 200PS and 10% better fuel economy. Might be something to consider a trial of when the car is run in.
-
Hmm I wouldn't of thought that the different settings would affect the engine. Did you notice much difference in engine noise in eco or sport?
-

A big difference internally due to the actuator doing it's stuff fully in sport, a little bit in normal and not at all in eco. On my Scirocco Sport seemed to just affect the actuator being on and heavier steering (as well as the standard fit ACC/DCC being firmer) - no fuel penalty at all for using Sport. Not so for the GTD it seems. Can't see why sitting at 75mph in sport on a flat road uses 10% more fuel than sitting at 75mph in eco on the same stretch of road.

Thanks for that info Monkeyhanger.
Like I say, felt like sweet package. Just want to ensure im getting value for money as an allrounder. Went for a nice rip around some local roads and a bit of M11 too with the salesman. Not experienced electric steering before (which was the only thing I didnt like really). Other than that, very nice car. Might ask him for an extended test drive to see exactly how much it drinks over my usual commute before I commit a deposit....

Depends what you're used to and what reality is once the car is run in. Personally, I was used to 50mpg on my 12 mile commute in the Scirocco, in Sport and putting my foot down quite a bit to get to speed, but otherwise having a fairly economic driving style once at the desired speed. longer journeys (30 miles and more) was expecting 55-60mpg maintaining 80mph on the motorway. If I drove my GTD like I drove my Scirocco, i'd probably get about 40mpg right now. Can I even match my Scirocco (with not a bit of eco tech on it) once the GTD is run in? Time will tell.
What was it about the electric steering? The variable lock length? My mate has this o his recently acquired Audo A4 and he keeps oversteering when he starts horsing about in it. You can change the steering to normal or eco mode within "individual" to minimise or negate the variable steering response.

Had to go to the dealership to pick up my tax disc today. For some inexplicable reason the DVLA send them to the dealerships and not the registered keeper (although that is probably registered keeper to be when the disc gets applied for). VW also strongly insist that the dealerships do not post them out to customers, as a way of getting the customer back in for feedback on the car.
Anyway, on the 15 miles there on the most direct route from work, most of the roads are 40-60mph with lots of stops and starts around the Felling bypass. Had a few chances to pull away quickly from the lights to get straight up to 40mph and stay there, in Sport all the way and I got to the dealership…52.8mpg for the journey, much better. Saw my p/x Roc up for £17995, collected my tax disc, had a quick word with the salesman after he asked how the car was a week in. He says his Tiguan improved considerably on 4k miles. All done, I set off back to work on the same route. Round trip was up to 53.6mpg, not too bad all things considered. On the short bit of central motorway I managed to get up to 75mph, the mpg for the trip was falling rapidly from a high of 56mpg.
Right now this car seems to make you pay a harsh fuel penalty for exceeding a cruising speed of 60mph. The stop start was unavailable for the whole journey, maybe it was doing a passive regen (although gear change recommendations didn’t seem to change from the norm and it wasn’t idling at 1000rpm). I thought that maybe stop-start was disabled in Sport mode, but flicking over to eco didn’t instigate a stop at a junction either. So I lost stop-start and gained mpg…..win-win!
It still seems flat as a fart in 5th and 6th next to the Scirocco – maybe that is my reluctance to get into the “clicky zone” of accelerator travel while the car is running in, or maybe I will see a noticeable difference in the car’s performance at 310 miles/500km like I did with the Scirocco.

With all that motorway mileage you should expect better mp than most - 60mpg if you're sensible (no more than 75-80mph constant cruising speed) and the car is fully run in. About £50 a week on that basis.

Following on from my 30 mile round trip to Sunderland, my commute home from work was 47mpg and a mile of that was at a crawl due to some unusual traffic caused by a burst water main. Might've touched 50 without that crawl. Seems the Sunderland trip might've cleared out the DPF. For the 30 mile trip and half of my commute home my start stop would not work, making me think I was undergoing a fuel-friendly passive regen.
-
Well, I now have a massive 265 miles on the car now, - but that will be increasing quite a bit over the next few weeks as I've got a couple of family trips from Cheshire to London and Oxford panned.
My long term up to now is.....drum roll......41.2mpg. Not brilliant, when my Scirocco (for the same journeys) was giving 45-47mpg, albeit with over 40hp less. Am I bothered.......nah,... for a couple of reasons.
1. With the mileage I have on at the moment, it's still factory fresh and feels tight as a drum. I expect once it properly loosens up over 2-4k miles, things will improve, and I seem to be permanently stuck in queuing traffic at the moment (which doesn't help).
2. It's been bloody cold ever since I've had the Golf (typical), at less than 8°C in the mornings, and I know from the winters in the Scirocco, that the cold weather does have a real good affect on MPG.
3. Even if the MPG stayed the same at 41mpg versus the Scirocco's 46mpg average, that's 5mpg difference so for my typical mileage, that equates to about £250.00 per year extra on fuel - not exactly a massive penalty for driving a 181bhp Hot(ish) hatch :grin:, and that's always assuming the MPG doesn't improve, which I'm sure it will.

Looks like your mpg is about the same as mine at similar mileage, minus 10% penalty for having a DSG box. My MFD indicated economy “since last fill up” is at about 47mpg, and my “long term” is 45mpg after a poor start with the “free” fuel hat came with the car. I am using V-power right now, so maybe my mpg is about 5% better than it otherwise would’ve been with regular diesel (assumed fewer DPF regens with V-power means better economy). What are you filling your car with right now?
It’s a relief to know mine isn’t abnormally low at this stage (they’re all 30% lower than official combined). Although I have only really tried putting my foot down hard once in 6th, I’m a little concerned that right now, 5th and 6th acceleration is as flat as a fart – more akin to the response I had on my 140TDI Scirocco rather than the 170TDI that followed it. Hopefully we’ll get that boost that seemed to come in on the Scirocco 170TDI at 310 miles/500 km.
Never really got much of a mpg improvement when the miles racked up on the Scirocco – maybe this engine is tighter than the last one or all the eco electronics are having a long learning curve to eventually get the best out of the car. The colder mornings and use of the headlights do make a difference – right now it is 6-9C when I go to work with headlights and about 16C on the way home with no headlights. 44mpg on the way to work typically and 49 mpg home if I don’t hit much traffic.
-
Just over 500 miles in my GTD. Mixed miles, probably 70% motorway plus quite a lot of stop start in traffic.
Long term = 42mpg.
Since refuel = 45mpg. Used Vpower Nitro+ and have done 350 miles on it.
Like others have said, going anything over 70 seems to hit the mpg quite badly.
-
Well now, that's getting more like it.
My usual run home tonight I got 53.4mpg, whereas I would have typically got about 55-57mpg in the Scirocco, and that's with less than 300 miles on the clock. Getting better all the time. Certainly better than the 41-42mpg I was getting at the start of the week, so I can see high 50's low 60's a distinct possibility on longer runs (this was only 12 miles).
Started off using economy mode, but didn't like (or wasn't used to) the coasting mode that you get with DSG where on the over-run, the engine completely disconnects from the transmission and you freewheel or coast. It's really weird as there's no engine braking so you have to be careful you don't get too close to the car in front (otherwise the object detection array complains :grin:).
Have just stuck it in normal for the time being (not even been into sport), but I gave it a little hoof tonight to accelerate onto the the dual carriageway, and my god.... even with a tight engine and not in sport mode, it's bloody quick and pulled like a steam train. Obviously I'm used to a 140ps Scirocco, so it's majorly impressive (maybe not so much if you have come from the 170ps engine ?).
If the GTD's are that quick, I'd love to have a go in the GTI with the extra 30bhp !
-
Well now, that's getting more like it.
My usual run home tonight I got 53.4mpg, whereas I would have typically got about 55-57mpg in the Scirocco, and that's with less than 300 miles on the clock. Getting better all the time. Certainly better than the 41-42mpg I was getting at the start of the week, so I can see high 50's low 60's a distinct possibility on longer runs (this was only 12 miles).
Started off using economy mode, but didn't like (or wasn't used to) the coasting mode that you get with DSG where on the over-run, the engine completely disconnects from the transmission and you freewheel or coast. It's really weird as there's no engine braking so you have to be careful you don't get too close to the car in front (otherwise the collection detection array complains :grin:).

Still extremely tight for me. 5th and 6th acceleration are pretty poor for me right now compared to my 170 Scirocco (seem on a par with my old 140), but in the lower gears it seems faster than the Scirocco. I'm knocking it down to 4th for a blast whereas i'd have left it in 6th for a burst above 60mph in the Scirocco. Done about 390 miles now, most of it in Sport and since fill-up (250 miles) it says 46.3mpg. If the computer is 100% accurate then it's matching the scirocco. If it's 10% optimistic (like the Scirocco was) then it's faring a little worse.
53.4mpg in a tight DSG on a 12 mile trip seems very good - is that all dual carriageway?
-
Actually not quite. From work I have a 15 minute queue in stop / start traffic to get off the industrial estate when our offices are (everyone pile out at the same time and there's only one route out to the main drag), to do 1 mile.
So 1 mile of queuing, followed by 9 miles of fast dual carriageway, followed by 2 miles of urban 40/30mph roads (but no real hold ups apart from the initial queue).

Sounds like mine should be a more economical journey than yours: 1.5miles through uncongested 30/40 roads to get onto the dual carriageway (straight up to 80mph), sit at 80 for 7 miles then 4 miles of uncongested 30/50mph roads going to work at 7am. Coming home at 4pm, there is a little more traffic, not much. I get about 44mpg on the way there (with Xenons on and colder ambient temperature) and 48mpg on the way back (without them). Are you sticking to 70mph? There seems (in my car at least) a far bigger fuel penalty for going over 70mph than there was in my Scirocco.
-
Mines got about 400 miles on it now. (OK might of been a little addicted to driving it). I've done a long journey today and got a reported 51.9MPG. That was mostly dual carriageway at 80-90, with a bit of congestion.
You're not wrong about the power, can't believe how fast and easy it is to get to license losing speeds!
-
I get about 44mpg on the way there (with Xenons on and colder ambient temperature) and 48mpg on the way back (without them).
Why would having headlight on make a measurable difference to fuel consumption?
My logic is this.
Even with Halogen headlights the draw would be less than 200 watts (this is way less than your average heated rear window) Xenons draw way less... and the car's output is 135KW. So the electrical draw for running with your headlights on is about 0.15% of the total output.
I can understand that running with aircon on would make a significant difference...

Cruising at 60mph where air resistance isn’t huge is probably only drawing 30kW/40BHP, so that 135W is a little more significant, but still only 0.5% on paper. Poor mpg is almost certainly down to the lower ambient temp that normally accompanies dark nights/morning and the car running colder for longer. Air temp at 7am on a morning recently has been typically 6-8C, gaining 43mpg. This morning at the same time it was 13C and the car did 47mpg on the way to work. Returning home from my commute, the car has done 46-49mpg with ambient temp of 14-20C recently.

Well mine is improving hand over fist. On Saturday night the wife and I went for a meal in Liverpool (about a 16 miles trip each way). Mixture of urban road, "A" roads and fast dual carriageways at 70 and 40mph.
Never even looked at the consumption when we got there, but coming back after a journey of 32miles, we got 58.6mpg (and the return trip was with the wife driving for the first time - and she doesn't hold back).
So if this improvement continues over the next few thousand miles, it will most certainly beat the Rocco for efficiency.
Obviously I don't yet know how inaccurate the computer is, but I guess it's out by about the same amount at the Scirocco, so I'm using the on screen figure from both as a comparison.

My dad reckons the MFD is about 5% out on his as opposed to 9/10% out on previous models. That could mean for me that 47.5 mpg indicated = 45mpg actual; same as Scirocco indicating 50mpg and only getting 45mpg actual. I’ll let you know when I fill my tank again.
When you say “not holding back” what are we talking here – quick to get up to speed and religiously sticking to speed limits, or getting up to 80mph on the dual carriageways etc? If I stuck to 70mph I would undoubtedly see an improvement, maybe 48mpg at 80mph becomes 53/55mpg at 70mph. Driving the car at similar speeds to the Scirocco (80mph on dual carriageway and quick to get up to speed) is my current mpg yardstick for the GTD, I’ll be happy when I can drive like I did in the Scirocco andd surpass my old economy.

True, I talked about 135Kw to emphasise how insignificant the power draw of headlights are. I'm certain that ambient temperature will have a much bigger effect especially with modern, direct injection diesels that tend to run much cooler than indirect engines of the past... And they will run cooler for longer - it can take half an hour in very cold weather to get warm air out of the vents. In some climates they have to specify pre-heaters for diesels...

Did the exact same trip to the dealership today to sort out those rear suspension transport cones as I did last week to pick up my tax disc. Last week was 53.6 for the round trip and this week was 55.4mpg = a 3.4% increase. I got up to 80mph on the 6 miles of the 30 mile round trip that was 70mph/dual carriageway and religiously stuck to 30/50/60mph the rest of the way (lots of speed cameras). If I’d been saintly at 70 then I’d have probably matched Norbreck’s 58mpg. Considering his is DSG though, I still think he’s doing better than me. The car has opened up a lot – I seem to have access to more torque in 5th and 6th above 60mph. About 450 miles on the clock now.
-
Good to see that these 184ps engines after a bit of a rocky start seem to be fairing quite a bit better than a number of the 1.6 TDI and 2.0 TDI 150ps units, that seem to be giving a lot of owners headaches with poor mpg at the moment !
-
I've heard and read some comments from 2.0 TDI drivers that avoiding Eco mode bizarrely improves their mpg, even on a manual. Maybe this could have a similar effect on GTD's?

Don't see the point of buying a GTD for it's ECO mode TBH.
-
I dunno, if you are on the M25 for instance and stuck in a constant flow of speed camera controlled temporay speed limits, I can see the free wheeling mode for the DSG boxes in Eco mode potentially saving a lot of fuel (disengages the engine from the gearbox when on the over-run, so the car coasts freely with no engine braking slowing it down) ?

One of my regular monthly journeys that involves plenty of that on M25 where you move a few yards at a time, and where performance is hardly in the equation.
Hate getting on and off the clutch and having someone brake sharply for no reason etc as stop/start so hoping the DSG/ADC is going to be my best friend then and maybe the best time to use the ECO, so will definitely be giving that a try and as do journey regularly enough be able to make some good comparisons.

Now that's more like it, my journey home from work last night (and don't forget, this is a DSG car) :smiley:
Doing 75 on the motorway (in the general flow of traffic), then 50 on a 5 mile stretch, with the rest at typical urban 30mph (traffic lights, roundabouts etc).

This is what i wanted to hear!
-
That's great news :smiley: what mileage are you at now?
-
Not a lot yet, only 550 miles. I'd expect it to get even better when it's fully loosened up - until the cold winter nights hit of course, when it usually plummets :smiley:
To be honest, at the moment, its a piece of pi55 to get 50+

This is why I was waiting for you guys to do some miles before started to worry on economy as my previous 2 cars was exactly the same in economy improving markedly as engine went through its first 1000 miles.
Reason we all went GTD is that economy is as much important to us as performance and it seems the GTD is going to tick both supremely
-
just been on another jaunt today and with 4 up got a peak of 55mpg with an average of 53mpg pulling up at home tonight. still not driving at even half throttle and with only 350 miles on the clock I think it's good. how many miles until I give it some beans??

Are you running in Eco mode?

Nope, as it says top left, "comfort mode" I've only tried Eco mode for a few minutes and the "coasting" function freaked me out :grin:

So a round trip to Luton for work with a mixture of driving and traffic on the m6/m1 then driving in and around Luton then getting back to Brum and driving from Solihull to birmingham city centre (through the city) yesterday have me the following on 40 quid worth of vpower diesel
http://i1346.photobucket.com/albums/p689/misterp86/image_zps5ce3a0a1.jpg
This morning driving from home to work which is a 6 mile commute of city driving including some traffic, roundabouts and a large 40mph stretch gave me 32.8 mpg. That's less than what I got in my 2004 a3 2.0tdi sline. I know it's still running in but I've now got just shy of 500 miles on the clock. It seems to be some way away from the quoted 51mpg you find in the brochures. I understand that your looking at an 8-10% decrease from the quoted. However, a whole 12 mpg less is a joke that's manual gti economy. From the looks of it if it carries on this way I should of just paid the extra for the gti. I do about 100 miles a month minimum on the mway monthly.
Should I be worried or am I doing something wrong.
-
MisterP: That is poor. Mine is averaging about 46mpg on its first tank, although I haven't driven it for 10 days, having been on holiday. Your commute is short and sounds a little congested, which doesn't help. I have noticed that my car's water temp gets up quicker than my Scirocco, but the oil temp takes just as long IMO. The MK7 seems to take longer in the journey to be economical, so is less suited to short journeys in my experience. If you don't get an improvement on your next tank or are plagued with regular active regens then you might want to get the car checked out.

Oil temp is slow going up. The prob is it's the same journey as my old tdi and that was hitting 40mpg. I know it's a short journey but still. My next tank I will put 30 quid of vpower diesel and see what happens. If no luck I will be dropping by the dealership. If it continues this way then it will be more expensive to run than a gti just out of curiosity the dsg may be changing up too soon. Do you manual drivers let it get to around 3000 revs before changing up.
-
TBH, from cold, for that short Journey, I doubt a GTI would be more economical - I would think it would struggle to break 30 at best ?

There is that but fuel prive difference would mean they are not that fat off unless I'm being naive. Let's see how it goes. I don't know if it's me but this was my second she'll fill up the first with normal diesel second with vpower and the first seemed to do better.
Or just leave home earlier so it's quiet lol and more time at 50
-
Sainsbury's diesel used and the economy is fantastic to be fair. Clocked over 1000 miles today so opened her up a bit with a cheeky little push down the M5....55 mpg! Happy days
-
Just over 500 miles in my GTD. Mixed miles, probably 70% motorway plus quite a lot of stop start in traffic.
Long term = 42mpg.
Since refuel = 45mpg. Used Vpower Nitro+ and have done 350 miles on it.
Like others have said, going anything over 70 seems to hit the mpg quite badly.
Sorry to quote myself but this was just as much for my interest as a marker before the tuning box affects the readings: -
Around 1,240 miles.
Long term = 44.6mpg.
Since refuel, around 200 miles = 47.6mpg.
Got 63mpg on a deliberately frugal 40 mile run last weekend. 90% A road but also included some town/traffic
-
Finally took delivery of the car on Monday and been enjoying it. 5dr manual GTD.
Had it on a decent run yesterday - 130 miles, mostly motorway with some city in between.
Best I could get out of it was 49mpg and that was driving very conservatively. I did use the adaptive cruise, economy mode etc.
Any suggestions to improve this? I see some people on here are getting very good mpg.
Cheers
Mike :smiley:

Mike f:
Unless you are trying to drive economically, eco is a massive waste of time, you will just end up frustrated with the throttle response and be pushing the car harder. Use any kind of cruise on any car and there will be a fuel penalty to be paid. If your economy is being hammered by active DPF regens then Shell V-Power may help get 5% or so improvement. Having been on a 130 mile motorway run, I doubt that is your problem right now. How many miles have you put on your car?
Most people's decent mpg has come about from 500+ miles, as the car loosens up (not just the engine needs to loosen). My long term mpg at about 450 miles in was about 44mpg, and since fill up on the first full tank is about 46mpg. I expext it to improve noticeably as more miles go on. If the mpg remains below expectations to 2000 miles then that's the time to start being concerned.
-
I have only got about 300 on it just now so I guess if it loosens up it might improve. Reading back through this the improvements seem huge over the first 1000 miles.
Totally love the car, surprised at how quick it is, thats coming from having an S3 before too - still fun to drive :D
-
I've now hit 1000 miles and economy seems to be improving.
Last week I did a 230 mile trip and averaged 51.5mpg. I did the same trip a couple of days ago and did 55.1mpg :smiley:
This was mostly motorway from Surrey up the M1 towards Leeds, similar traffic, weather conditions and speed (75-80 on the motorway).
The previous trip was on a 50/50 mix of BP Ultimate / supermarket fuel. The latest one on a full tank of BP Ultimate. I've run BP Ultimate in previous cars and seen improvements in smoothness and responsive but never a noticeable benefit to economy. So I'm assuming the improved mpg is just down to the engine loosening up.
-
Must say as the mileage increase so does my daily mpg that I'm seeing.
-
Replacement of my first full tankful of fuel today. At 515 miles in I covered 414.5 miles with 9.77 gallons of V-Power diesel, which is 42.4mpg vs indicated 46.5mpg since fill up. My MFD is reading 9% optimistic.
I'm pretty disappointed in this TBH, seeing as I would have probably only gotten 40mpg using a lesser fuel with more regens happening as a result. Comparatively driving far more carefully than caning my 170TDI Scirocco (bereft of any eco tech) and still getting 50mpg indicated/45mpg actual without using V-Power. If I drove my GTD like the Roc, i'd probably be around 37mpg actual.
I have noticed that on many occasions, the gear change suggestions have me driving in a lower gear than would have been normal for the Roc at the given speed, yet the 2 cars seem to be geared pretty much the same. Managed a paltry 43mpg (indicated) on my commute to work today. Will be hoping to crack 50mpg indicated when I shoot through to Hartlepool this weekend or I will be really disappointed.
Speaking to my dad last night, his GTD has now racked up 6k miles and is averaging 49mpg indicated/47mpg actual (his MFD seems more accurate than mine), still well down on his MK5 170TDI.

Turn climate control off

Turn climate control off
Climate is off. It's set up for eco on the cooling, but I rarely have the aircon on - it's probably been on all of 2 hours in the time I had the car, and those were at motorway speeds. haven't been using the cruise control either.

I think you can only get decent mpg if you keep it to a max of 2k revs :angry:
-
My mpg has taken a turn for the worse with ambient temp falling to 10C on the way to work and 14C on the way back.
For my last 5 commute trips of 12 miles each (3 x to work, 2 x back) I haven't cracked 43mpg indicated, which is probably 39mpg actual. My journeys have been clutter free, so it's not down to traffic etc. By the time the trip mpg has reached 40mpg in the GTD, I would've been at 48-50mpg in the Scirocco.
On my commute, gains over 40mpg seem to be very slow to where it finishes at the end of my journey. This is despite the car warming up a bit quicker, being a tiny bit lighter than the Scirocco and having eco tech the Scirocco doesn't have. I also used to have quite a heavy right foot in the Scirocco that my GTD hasn't really experienced much yet. Fuel economy above 60mph seems sh!te on the GTD. Do 70 or 80mph cruising speed and my mpg suffers greatly compared to previous high output 2.0TDI engines.
-
MH. Same thing for me x I don't use the ac and if required its on Eco mode. God knows what is going on I have emailed the dealer as I am due there on sat may just revert to standard shell. And fill up v power once in a while to assist with the regen/cleaning.
-
My brim-to-brim mpg so far -
1st tank: 47.9 (48 indicated, 50/50 BP Ultimate, supermarket fuel)
2nd tank: 48.8 (50.4 indicated, 100% BP Ultimate)
These both include a daily 7 miles stop/start commute in heavy traffic around Leeds and a trip down the M1 towards Surrey.
On the journey back south last night I managed an indicated 55mpg in reasonable traffic.
-
Although mine still only has less than 700 miles on it, I feel it's already beating (or at least matching), my old 140 PD CR Scirocco BM economy. My averge (for my typical journeys) was 47 indicated, 44 actual, whereas on the GTD I'm getting 48.7 indicated, 45.8 actual.
Never expected to get anywhere near VW's figures, but I always said, if it was as good as my old Scirocco, I would be pleased and I am.

Lucky you! Wish mine was doing that. My commute is 12 miles long and is as follows:-
1 mile at 30-40mph, with a few roundabouts (the car is up to about 30mpg at the end of it, water temp about 80C/40mpg in the Scirocco).
6 miles on dual carriageway – straight up to 70-80mph and stay there if volume of traffic allows it (the car is up to about 40mpg at the end of it and oil is fully up to temp/48mpg in the Scirocco).
5 miles on mixed 30/40/50mph roads, sticking to the speed limits as there are cameras about (car creeps up to just shy of 43mpg by the time I get into work/50-52mpg in the Scirocco).
Although I put my foot down to get up to speed quickly, I have an economical style of driving once at required cruising speed – anticipating ahead traffic well, letting the car do a lot of its slowing down with its own momentum and braking a little later as a result – I don’t usually waste the kinetic energy the car has generated!
Will probably revert to standard Shell for my next tank and see if the regen frequency stays low. I didn’t use V-power in my Scirocco, but many people from various forums swear by V-power for keeping the regens low and it seems to have worked in my case after a few very early regens (unless early regens are the norm for all cars for the first 200 miles or so and then they settle down?).
I wonder what fuel is being used by those experiencing decent/expected mpg?
-
So what are you guys getting for total miles on a tank before needing to refuel? I believe the fuel tank is smaller on the MKVII.

It's 50L instread of 55L on older VW Golfs/Scirocco. I got 414 miles from Full to 30 miles range left (43.4mpg), I was disappointed with that - used to do about 530 miles in the Scirocco with 10% more fuel.

To be fair my daily commute is pretty terrible where I struggle to get 38-39. It's the long, steady motorway trips that have been pushing my average up.
-
For info, I'm just on Standard Shell or Esso Diesel (nothing special).
Only had 2 regens (one active) in the first 700 miles, and the first one was at only 35 miles !

V-power does have a lower Cetane rating (52) than standard Shell (56), but I thought that the lower Cetane rating would be cancelled out by fewer regens hampering mpg. If it isn’t reducing the incidence of regens then standard Shell will probably give you more mpg.
-
35 pounds of v power has given me 70 miles at 36mpg not impressed back to normal shell for me. Also how do you know when's its regen'n. Finally I'm getting a slight click in reverse when I full lock booked into vw immediately next Friday earliest to get it looked at so I'm going to get them to look at the fuel aswell.
-
Definitely time to ditch the V-power and try the normal stuff. V-power is less dense than normal diesel too, so would seem to have fewer hydrocarbons in it or same number of hydrocarbons, but smaller chain length and therefore less chemical energy.
-
First 100 or so miles yesterday averaged 57mpg on the computer (having reset after collection though). Mainly steady cross country driving with 10 miles or so at 70 on the motorway. Not an onerous test but looks promising.
Using my Garmin GPS the trip counter was bang on for accuracy; the speedo only read 2 mph fast at 70.
Brimmed the tank last night for a "real" test... :smiley:
-
To start my tuning box mpg experiment properly, I had to use a proper "control" and fill again with V-power to be assured that any gains weren't from filling up with normal Shell and not the doings of the TDI-tuning box. Did 183.9 miles on 19.83 litres = 42.5mpg vs indicated 44.0mpg: 3.5% optimistic, quite a change from last time when the disparity from indicated to actual was over 9% for my first tank. Maybe the computer has an accuracy "learning" period. It seems that this fill up vs last fill up is nowhere near as bad as I thought.
It will be interesting to know if any mpg gains are seen on the computer or only in brim to brim measurement because the MFD calculates MPG based on fuelling system signals sent by the ECU before the tuning system alters them.

My car now has 1020 miles on the clock. Took it to Ellesmere Port on sat round trip of 150 miles got 55mpg on a 25 pound fill up. I'm think we are getting somewhere. This week mom through to tues I'm averaging 30mpg not pressed. I have it billed in for a knocking sound in reverse. I have asked them to look at the economy cos this is a joke.

30mpg around the doors? What kind of commute are you doing? Are you getting lots of active regens caning your mpg? I’d hope not now you’ve cracked 1000 miles unless your commute is ridiculously short like 3 or 4 miles, the car is sat crawling along in heavy traffic all the time or you drive like a maniac.
£25 on assumption of £1.369 cost per litre of Diesel is 3.99 gallons. 150 miles over 4 gallons is 37.5mpg. 55mpg indicated I assume? Can’t see there being a disparity of the actual mpg being only 68% of MFD reading. How sure are you that your 150 miles swallowed up a whole 4 gallon fill? I reckon you’d have had some of that 4 gallons left. 55mpg indicated should be 49-52mpg actual depending on 5% disparity or 10% disparity. Take worst case actual 49mpg (from indicated 55mpg), you should have 0.92 Gallons left of your 3.99 Gallons doing that. 49 actual (55 indicated) mpg seems about what I would anticipate getting on a 150 mile trip maintaining 80mph, or thereabouts. If you were maintaining 60-70mph and only got that as well as your 30mpg around the doors then I would definitely say your car is abnormally thirsty. On clear roads, I’d expect to be pushing 60mpg (indicated) if I was maintaining 60-70mph on a 150 mile round trip. How is the traffic when you make your journeys?
-
Stuck to 80 really not canning it at any point I like cruising :grin: Around doors no traffic really (out of the ordinary) but still pottering around town for about 6/7 miles is really bad for my mpg. And if the disparity is anything to go by it comes of as somewhat thirsty. It's booked in to get looked at tomorrow. I don't know how much light the 'master technician' can shed.
-
Well, had my second fill up today (standard Shell Diesel).
MDF indicated an overall fuel consumption of 46.2mpg since last fill up. Filled the car to the second click of the forecourt pump (as I did last time), put in 42 litres (9.24 gallons) for 422 miles = a calculated average of 45.67 mpg (so the computer seems very accurate).
For the journeys I'm currently doing in crawling traffic and no long motorway runs, I'm pretty happy with that as my Rocco wouldn't have faired any better.
-
Now the temp has dipped, I don’t think my Scirocco would have fared any better than your actual. I’d be looking at a probable 50mpg indicated and 45mpg actual. Considering yours is a DSG (and should be 10% thirstier than a manual diven the same way), assuming we have a similarly economic driving style (you’re not driving like a nun, you accelerate quickly to cruising speed, but you do preserve your momentum as much as you can with good anticipation of the road ahead etc), you’re doing well. It will be interesting to see if a switch to regular diesel for me yields great improvement.
Seems quite honest of VW to make the computer more representative of reality. If they’d kept the traditional 10% disparity, most people here not interested in brim filling would have seen an instant “improvement” in their mpg vs previous gen. I bet your calculated average of 45.67mpg would have yielded an MFD indicated mpg of 50/51.
-
I'm pretty much stuck in comfort mode at the moment, as due to traffic etc. there's no point for me in sport mode and nailing it for a couple of hundred yards between lights. I don't accelerate particularly quickly, but then not driving like a nun either - just, well, normal !
As the cars only got 850 miles on it as well, for the few motorway runs it gets (6 miles between 2 junctions), then I'm running at 75mph ish (not had it over 80 yet), and around the houses its just the usual applicable speed limits which I stick to as there are too many speed cameras around here. To be honest my whole commute (route, speed etc.) is the same as when I had the Scirocco. I always said if the GTD was as economical as the Scirocco but with an extra 30+ hp to boot then I would be delighted.
I've just looked at my fuelly account, and long term over 3000 miles in the Scirocco (unfortunately I only started by Fuelly account earlier this year) it averaged 45.5 overall. My GTD at just 850 miles and 2 fill ups is already at 44.3 mpg, and I expect this to increase slightly as the engine loosens up over the next few thousand miles (the Rocco was about 10% down on it's long term when new for the first 3000-5000 miles ish).

Stuart, Fuelly is a website where you can log and upload your fuel consumption data, this then adds to a mean average worldwide for all similar cars and gives potential buyers of that car access to real car fuel data (rather than the manufacturers figures).
To be honest, I just use is as a record of my fill ups.

If you’ve only had it up to 75mph on the motorway, I suppose that could mean a 3-5% difference in mpg than getting it up to 80mph and staying there whilst on the motorway. I guess if you anticipate the road ahead well and come off the throttle early when approaching a junction/roundabout/static traffic then the other parts of the way you drive (a little more light-footed than me) will probably have you a bit more economical than me. 45mpg actual on your 140TDI DSG Scirocco was about the same as I was getting on my 170TDI manual Scirocco. I suppose the extra power and associated thirst on mine was mitigated by the DSG fuel penalty on yours.
I am finding with every generation of TDI that they drive more and more like a petrol car in the way that now there seems to be a large penalty for putting your foot down. In the old PD units, they pretty much gave the same MPG whether you hammered it or drove reasonably carefully (so I hammered it).
Still seeing off the DPF regens? They seem to be fewer and further between as the miles were going on. I think I had 3 in my first 400 miles, and another one 400 miles later – I am also at around 850-870 miles.
I never really saw an appreciable gain on my Scirocco. Maybe if you’re gentle with the car you get a slow and gradual run in, with the gains stretched out over a longer period, whereas if you’re not so gentle (but not really mean either), you see those gains level out over a much shorter period. I think my Scirocco literally gained about 2mpg on the longer journeys and next to nowt on the shorter ones as the miles went on.
-
Your really giving this a lot of thought aren't you MH :grin: :grin: :grin:
You sure you shouldn't have gone for a Prius or a hybrid (only kidding honest) :evil: :evil: :evil:
-
Just realistically expecting the GTD to be 10% better than my Scirocco and it’s actually looking like it’ll just break even – 20% improvement in fuel economy for the MK7 my arse! :evil:
I’m sure VW have moved the goal posts on that score.

Yeah, i use it for my Polo just now. Find it pretty good! I've tracked the last 48,000 miles with it.
Planning on doing the same when i get my GTD :)

So now had my car for about 800 miles and on a 140mile journey mostly motor way dual carriageways driving sensibly I still cant get near 45mpg...
First tank I got about 410 out it and second tank about 395...
I would have thought I would have got most of the gains from the engine loosening up by now....
Some experiences on here seem to be better, what is the key for good MPG!?!
I know I didn't buy the car to boast about the MPG but I did want a car that was 50+ due to the type of driving I was now doing. VWs claims seemed to support this but in retrospect I would have been better getting a MK6 GTD six months ago and saving some cash and time rather than waiting for this which seemed to boast far better economy figures...

Now that's more like it, my journey home from work last night (and don't forget, this is a DSG car) :smiley:
Doing 75 on the motorway (in the general flow of traffic), then 50 on a 5 mile stretch, with the rest at typical urban 30mph (traffic lights, roundabouts etc).

Witchcraft - definitely not VW's doing! :laugh:

Managed to get 49mpg on a 130mile run today but when I filled up with fuel and worked out the mpg myself it was only 43 mpg.
I would have thought those things were accurate but seemingly not..

I have had about a 10% discrepancy between indicated and actual mpg on my first tank, and about 4% on my second fill-up. Most people have seen a 5% discrepancy, better than previous VWs that are typically 9 or 10%. For you to have a 12% discrepancy is really bad.
-
I have just past the 1k mile mark today and my long term average is 40.2mpg
Running around town I am getting 40ish. Best i have had was 50.1 on a 110mile journey. Tomorrow I am on a 240mile journey so im hoping for 55+.
I did have spells of really hammering the car about and putting it through its paces but even when im trying to drive like a nun I am still getting poor figures.
I love the car but I feel I have been a little bit misled by VW and their MPG figures. Wish I had gone for the GTI now, apart from the terrible red seats! :laugh:

Following someone else that was only doing 65-70mph on the Motorway and no hold ups. :grin: :grin:
To be fair, now the temperatures dropped, I'm not seeing that any more. If I drive quite conservatively on the way home (but not like a granny), I can easily get 55+ mpg, but a little spirited, and it drops quickly to about 47-49mpg. However, for a 184ps motor, that's still not bad.
Guess If I wanted the best possible economy, I'd have either purchased a 1.6tdi Bluemotion or a 3 Series BMW 320d efficient dynamics (but that wouldn't have been any fun would it).
As a laugh, my Wife's Polo Blue GT had to go in the dealers on Friday as the side skirt bonding had started to come away. Sorted in a day, but as I know the dealers well, rather than a usual up!, I loaned the wife my GTD for the day and the dealer gave me a MK7 GTI (non pp) - which was the salesman's car. I have to say, whilst quieter and smoother, it didn't feel massively different than the GTD (and it had about 6,500 miles so should have been run in). Anyway, for my journey to work (just driving normally), I got.......29.5mpg (gulp), and having a bit of a play with the extra power on the way home 26.7mpg (according to the MFD) !!. Definitely likes to rev and is a much more playful car that the GTD, but I'm happy with my choice (and do prefer the non red accents of the interior and exterior - although that's a personal thing I know).
-
I got an indicated 49.5mpg on my drive to work today (12 miles mixed driving), what that translates to in actual I don't know yet - i'm guessing around 47.0mpg with a 5% discrepancy.
I have noticed with mine that putting my foot down early into the trip and getting the engine warmed quicker does seem to help my mpg across the whole journey. Not saying thrash a cold engine, but driving like a nun while it is cold definitely hampers the warm-up process on the shorter trips and kills your mpg.
Tonight is the night I top the tank back up to full and see what effects the TDI-tuning.co.uk box has had on my mpg. It's looking good. My tank looks as full with 210 miles done vs 183 miles done without the box when I last topped the tank up on the day the box arrived. The tank dial looks one notch over 1/2 full right now.

What were people getting out the MK6 GTD?
I deliberately passed up on buying a Mk6 in March this year and held off for the MK7 since the MPG stated was so much better.
Combined figure for the MK6 was 53.3 and on the Mk7 it is supposed to be 67.3!! So considering I work out I am getting about 43 I am not overly impressed.
Fair enough I am not expecting to get close to 67mpg but 43mpg isn't too hot.
At how many miles can you say a car has been "run in" I am about 1100 at the moment.

Can’t speak for the MK6, but for my Scirocco 170TDI which is pretty much the same car under the skin (possibly a smidge more aerodynamic than a MK6 GTD), I would get an indicated 48 (44 actual via brim method) mpg on my mixed 12 mile commute in the winter, about 52 (47) in the summer and on a decent motorway spell 55mpg (50) was possible at a constant 80mph on at least a 30 mile single journey and getting better to journeys I did up to 350 miles long with 59mpg (54) with the aircon on all the way on a hot day. That was with a pretty heavy right foot whilst accelerating but quite an economic style once at speed. The Scirocco 170TDI has absolutely no eco tech on it (unless you consider the MFD gear change prompts to be eco tech)
One thing I did notice with the Scirocco (assuming MK6 GTD was the same) and every previous TDI I’ve had is that MPG didn’t appreciably improve with running in. Some talk on other forums for 2.0TDI (150) GT Golf 7 suggests that mpg does appreciably improve from 0-5k miles for some, but not all.
At 1100 miles your car should be considerably looser than when you got it – you have surpassed the traditional 1000mile/1500Km running in period. My first journey home from the dealership in June in my Scirocco resulted in a 53mpg (indicated) trip and it pretty much carried on like that, albeit with an appreciable development of extra power (but no extra mpg). I do remember my 170TDI being extremely tight for the first 320 miles/500Km, feeling very underpowered. Almost like the flick of a switch at that mileage threshold (some running in program?), I had a lot more power on tap. A few others in 170TDIs had a similar running in experience but was not something noticed by the 140TDI Scirocco drivers on the forum.
Are you using Shell V-power or normal Diesel? Is your commute long enough to get the car up to temp and start seeing decent mpg? I have found that the water temp gets up to normal quicker on the MK7, but oil temp takes just as long as the Scirocco – even though one of the reasons the MK7 is supposed to be more economical is that it heats up quicker due to the redesigned integral exhaust manifold etc.

My mk6 GTD has averaged between 47-50mpg in the 14000 or so miles I've had it. So say less than 6mpg from VW's claimed combined figure.
MPG went down a bit after the REVO remap which I was surprised about, as I was expecting at least a 5% gain (and I wasn't hoofing it everywhere).
Pretty shocked at the appalling mk7 figures to date, if I wasn't getting closer to high 50's/60mpg I would not be happy as that was one of the big selling points!

Just normal diesel and the driving I do is very mixed.
Yesterday I had a 130 mile journey to do so I filled it up before I left and filled it up when I arrived and did the sums on MPG to confirm the accuracy of the onboard meter.
I deliberately drove conservatively to try and see what the best I could squeeze out it was. Mostly on motorway doing 70-75 with a few sections through cities and down to 50 etc. To be honest the car seems so much more economical when cruising at about 50 through towns and cities than it does around 70.
I don't expect the running gains over the next month or so so to magically give me an extra 10mpg I am looking for an if anything I'd like to be driving it a bit more sporty so if anything the figures I had would drop to below 40 in reality if I was to do so.
VW must have managed to get the test results somehow under test conditions so an improvement over 43 must be possible. Especially when I am driving it like a nun.

It might be worth having a read of this http://www.theaa.com/motoring_advice/fuels-and-environment/official-fuel-consumption-figures.html (http://www.theaa.com/motoring_advice/fuels-and-environment/official-fuel-consumption-figures.html)
What the article is saying is that they manufacturers have, over the years, become wise to the ways of showing very good results on the tests used in the EU; the example used is stop/start - the lab tests have at least 10% of the test as idling - if you don't use this technology either because you don't stop for long enough (I read elsewhere that you need to be stopped for a minimum of 5 seconds to see a benefit) or you've turned it off then you will see substantially worse results in real life than the test.
The amount of resistance used on the rolling road in the test will make a massive difference as will running with the aircon off etc.
The upshot is the gap between official figures and what you should expect is becoming wider. A new test is in the offing according to the article... but is unlikely to be used before 2017...
-
My results on the MK7 GTD have been with the aircon off 90% of the time. I generally only put my aircon on when the speed is enough to have a lot of air running over the A/C radiator for very efficient heat exchange. Anything less than 40mph and I’ll open a window to cool down rather than make the A/C pump work a lot harder..
I have noticed though that the economy seems to really take a dive when you cruise at more than 70mph compared to previous TDIs. My aforementioned Scirocco figures are based on 80mph cruising speeds when I am on a 70mph rated dual carriageway or the motorway. On the warm-up cycle especially my GTD appears to be 20% thirstier than my Scirocco was at various reference points towards the first half of my commute. By the time I leave the coast road I am at around 42mpg compared to 50mpg at the same point in my Scirocco.
I’m not sure whether driving so softly will have a detrimental effect on economy due to the car struggling to get up to optimum temp for passive regeneration of the DPF before your short(ish) journeys are over.
The goalposts have definitely been moving on these tests, but if everyone is at it, can you really do better elsewhere? At least we get a £20 tax disk off these fantasy test mpg results.
If you are in uncongested traffic and so rarely need to use the stop start then your mpg should be better, not worse. I use a judgement call on my stop start. If I’m going to get away from a stop within 10 seconds, I leave the clutch dipped to keep the engine running. My commute is generally free-flowing, stopping only at a few roundabouts and traffic lights.
I do wonder what the long term impact of stop-start tech is on engine longevity due to increased wear (and to a lesser degree because of lower cost – battery longevity), especially for the petrol engines where the fuel itself has no lubricative properties.

You're right. My comment was that if you run in congestion and do not use the stop/start tech or you do and the stops are very short then you will see a detrimental effect on your economy versus the test...
Knock about 25% of the official figures and you won't be far off... if you use that as an expectation and you do better you will be happy.

I agree with this and I noticed this first hand. I went to Cheshire from birmingham, a 150 mile round two, the weekend before last car according to the on board computer was hitting 50mpg plus whilst cruising at 70-75. Last Saturday drove to Gatwick which was a 300 mile round trip all motorway. I was cruising at a slightly faster speed of 80-85 and the car only managed a reading of 46mpg.
Still pottering around town and I get a rather reduced 37 mpg. I still think that the from start reading is rather inaccurate. Had the dealership look at it and I was told no issue with the dpf filter also they don't see how the from start reading should get anything above what in getting. Which, coincidentally I think is a load of horse sh!t.

You should not be surprised that fuel economy suffers as speed increases - once the speed gets to a point where aerodynamics are a factor. The air resistance increases in proportion to the square of the increase in speed... Therefore, as your average speed becomes greater you should see an increasing decline in fuel consumption.

I’m not surprised that economy suffers as speed increases (well aware that air appears thicker due to increased wind resistance as the car speeds up – the main reason that a car with twice as much BHP is nowhere near twice as fast), I’m surprised at how much it affects the GTD compared to previous VWs to go a modest 10mph faster (80mph vs 70mph). For a car that is supposedly 20% better on fuel economy than the previous generation, realistic expectations are that a MK7 GTD should be as fuel efficient straight out of the box as a run in MK6 GTD, and then you should see gains as the MK7 runs in that justified the “20% better mpg” tag. For the MK7 GTD to be 30% away from book combined figures for most users right now, compared to 5-10% away from book combined being easily achievable in MK6 GTD/Scirocco 170TDI, that is the issue. Can anyone realistically expect to see 20% running in gains on their new GTD to bring them routinely within 10% of book combined after 5k-10k miles? I very much doubt it. Seems plenty of people here are having to do very long journeys to crack 50mpg in their new GTD. An 80mph cruise on a long journey (100+ miles) in my 170TDI Scirocco would have yielded an easy 55mpg in the worst of weather.
-
MH this is exactly my point. You can understand being 10% off the urban and combined cycle figures but 30% or more that just isn't right. Factor in the gains after running in I honestly can't envisage a 20% increase after running in.
-
I refer you to the link I posted yesterday and my comment that as the official test is not representative, if you expect 25% worse fuel consumption than the official figures, then you will not be disappointed.
In the end, I suspect that modern ECUs are so sophisticated that they may even be able to recognise that a test is being performed and behave accordingly...

It’s not representative now, but it was up until recently by my past experiences of not having to try too hard to get close to official combined figures on a shortish journey (<20 miles) and surpassing it on a longer one.
Do VW officially state that it isn’t representative of real life situations anywhere? Haven’t seen anything to that effect myself unless you take the use of “up to”.
What I have seen quite prominently on a Mazda TV advert for the Mazda 6 is that they declare that their official combined cycle results may not be representative of real driving results and are to be used for comparison with other car manufacturers only. It would seem then that Mazda are quite honest and by association with their non-real world test figures, the same can be expected of the other car manufacturers also (for it to be a fair comparison). I do think it is completely wrong to just accept 75% of claimed combined figures as “doing ok” when they have sold the MK7 as being 20% better than the previous generation on fuel usage.
Although I do bang on about mpg quite a bit, it isn’t the only reason I bought a GTD. If they’d said here it is, you might get 50mpg if you’re lucky, but aim for 45mpg I’d have probably still bought one, but some others maybe have bought for the non-existent fuel savings.
With the weight saving*, start-stop, brake regen etc tech not present on my last car I think it’s fair to assume you would see better mpg on the new one than the last gen MK6 GTD or Scirocco 170TDI.
* Weight saving “up to 100Kg” – another stretch of the truth. Pretty much a universal 27Kg saving on any MK7 Golf that retained the multilink rear suspension (>120PS).

I'm not saying that this is the way it should be, just the way it is...
It is not all cars either - being cynical - cars that suffer this problem most are those in the competitive mid-range hatch market. "Honest John" shows that some cars - for example Jag, Porsche achieve the same or better than their official figures and diesel powered cars seem to be worse.
My girlfriend, a few weeks ago, took delivery of a new 120d M-Sport which should officially do 65.7mpg on the combined cycle, the trip computer, last I looked, was reporting 48.5... more than 25% off... Now, she is not the most economical driver but I would have expected better...
The point here is that the test is not representative of the driving she does... the extra-urban test only briefly reaches a peak speed of 75mph and has an average speed of 40 iirc - she, on the other-hand, has a commute of about an hour, often in congestion but when it is clear she will settle into a cruise higher than the peak speed of the test...
With my likely driving in my GTD when it arrives and is run-in, I would expect to see high-forties to low-fifties as mpg... Anyone expecting to see close to the combined figure for the GTD (67.3) would need to drive as per the tests... and even then I reckon they would only be within 5% because there are so many other factors at play that the test doesn't really address...
The previous tests were not seen as representative (urban/56/75) because they did not represent normal driving but neither do the current tests and having read what is proposed I doubt the upcoming ones will either...
-
Vw were recently given a slap on the wrist for the figures they quote and the manner in which they advertise it they have been told to state as per Mazda. That being said you would be silly hoping for the quoted figure but 30% discrepancy. That's taking it too far.

From the article I posted yesterday:
A recent study by The International Council on Clean Transportation (ICCT) showed that, on average, ‘real world’ fuel consumption for new cars was 21% worse than the figure quoted by the vehicle manufacturer.
No one standard test can accurately reflect the diversity of driving style, road, traffic and weather conditions, and drivers have probably always expected some variation compared to official figures, but in some cases the gap is now so wide that drivers are accusing manufacturers of misleading claims and even suggesting legal action.
and more
Research by TNO and Travel Card in the Netherlands ... showed that cars use over 35% more fuel than manufacturers claim.
And the AA's opinion (not mine)
If you assume that the car will be capable of a fuel economy 25% less (worse) than the official combined figure quoted by the manufacturer you shouldn’t be disappointed, and may be pleasantly surprised.
As I said earlier, I'm not saying it should be like this but it is. In the end the official tests are to blame, the manufacturers optimise their cars for those (when they feel it is important to do so)... make the tests more representative and the discrepancy will be less...

I've been averaging around 45mpg, but got 55mpg on an half hour run tonight. It is really cold and car hasn't been driven for a few days, so it took forever for the oil temperature to get to a decent level. I'm sure if the car was warm, I would have got close to 60mpg.
Not sure if it is in my head but the car felt a lot looser tonight and that bit faster. Just went past 750 miles.
Be delighted if i get anywhere near 50mpg.
-
I;ve been getting between 45-60mpg on my runs. This is on the a182 (40/50/60mph) road and the a19 (70/80mph) road. Weirdly I seem to get better MPG in Sport mode, which I can only put down to needing to press less hard on the throttle?
Disappointed to not get into the 50s more with the MPG but it is no worse than my last car (1.4 Ibiza) with a lot more power on tap too.

Are most of your journeys long and at constant speeds. Wish I had your mpg, i'd settle for 50mpg indicated right now if it meant 47mpg actual.

Yeah mate, I'm doing about 35 miles each way. Durham - > Redcar

First 100 or so miles yesterday averaged 57mpg on the computer (having reset after collection though). Mainly steady cross country driving with 10 miles or so at 70 on the motorway. Not an onerous test but looks promising.
Using my Garmin GPS the trip counter was bang on for accuracy; the speedo only read 2 mph fast at 70.
Brimmed the tank last night for a "real" test... :smiley:
My first refil calculated at 53 actual vs 55 indicated. Mix of local commuting and longer distance including maybe 20% at 70 on the motorway. Working through the next tank; 750 on the clock now.
-
Skinnee D: Sounds a lot better than most are getting. I'm getting 45-46mpg indicated average per tank, which equates to 42.5mpg actual. Car feels a little looser since it had 10 days with the TDI-tuning.co.uk box on. Not that it feels looser with the box on, but the car with the box off again feels looser than before I got the box (with an extra 250 miles on the clock).
-
My GTD MPG seems to be improving even more. After a good steady drive to work this morning I managed 50.5mpg

Interesting MH, though I'm probably drive like a bit of an old git at present in fairness :grin: Will be interesting to see where the numbers go once it gets opened up a bit more, will avoid the temptation until past 1000 or so. I took your advice and only used Sport mode from the outset plus Eco for the A/C - thanks for that :smiley: Also using Eco for the ACC (rightly or wrongly).
What mileage have you got to on yours now?

Up to about 1100 now, which isn't a lot for seeing loosening gains on a MK7 it seems. Ive never known a VW TDI take this long to start to loosen up, in my previous 6 cars 500 - 100 miles and you were done. Hopefully there's more to come!

One of the VW sales guys had his own Scirocco 177 tdi and reckoned it took 3000 miles to eventually loosen up and really get going. Maybe the low friction bearings in the latest VAG engines take more time to bed in...?
Could the different makes of "bluemotion technology" tyres being supplied have differing rolling resistances? Mine happen to be Continental (which I have no previous experience of...) Just another variable :undecided:
I filled up at Sainsburys the first time. It sounds like the sourcing of supermarket fuel can be unpredictable so maybe I won't make a habit of that.
One surprising thing to me is that the auto stop is already working a couple of minutes after heading out with a completely cold engine - I thought it was blocked until the engine had warmed up. Maybe this will change when the weather gets colder.
My last Golf was a GT PD - you had to cane that to get it under 50mpg indicated.
-
My last 2 VW diesels took a good 10,000 miles before their economy and performance achieved what I hoped. My 170 Scirocco struggled to get past mid 40mpg until after it's 1st service and it's performance was still improving at 15,000. I really don't think its realistic to expect good mpg straight out of the box, mind you if my GTD ever arrives I'll be able to contribute then.
-
My Polo Bluemotion took around 20k miles to start returning a consistant mpg following a steady increase from 5000 miles onwards.
Now sits at 75mpg on a regular basis. 70mph for a 45 miles trip, about 65-70% of this is motorways. :smiley:
-
Maybe VW have changed the point at which the MK7 is run in by either being exceptionally tight, or clever ECU limitations gradually lessened over a long period? With my Scirocco 170TDI, I was initially disappointed, it felt like it had the performance of the 140TDICR Scirocco that came before it, but after 320 miles/500Km, as if a switch had been flicked, it opened right up (and others had the same experience). mpg was always good - very hard to get under 50mpg indicated/45 actual except in the worst of winter.
I had the chance to test my performance benchmark by which I have judged my last 4 cars, now i've passed 1000 miles. Getting onto the coast road and accelerating hard (about 3/4 throttle) to the point at which I pass a certain sign: 140 PD MK5 = 70mph, 170 PD MK5 = 80mph, 140TDI CR Roc = 78mph, 170TDI CR Roc = 83mph.......MK7 GTD, throttle down to click point = 79mph. :angry:
Not sure whether there is a lot of improvement to gain still or whether in the past TDI output was less tightly controlled. A well run in one would go a fair way over book output, maybe now they can be accurately limited to book output with a more sophisticated ECU? Did I have a 170TDI putting out about 190PS, or do I have a GTD putting out less than 184PS? Roads were dry, so seemingly no grip issues. Scirocco had 235/18 tyres vs GTD 225/18 tyres, could that be significant if the traction control didn't intervene?
One other factor to consider - i'm on V-power right now, will have to see what standard Shell does to me with higher Cetane.

Driving to St Andrews yesterday from Stirling in my three year old a3 i got 67.1mpg...turned out to be so addictive trying to constantly improve. I have evidence if know one believes me. Surely the gtd will manage 60 if you kbow how to drive it

The GTD could do this fully run in and doing a constant 55mph on a clutter-free motorway, but what's the point of sitting at 55mph on the motorway? It should be capable of doing this at a constant 70mph. My last car could exceed it's published combined mpg doing a constant 80mph on a clutter-free motorway. How fast were you going to achieve those figures and is that a 1.6/105, 2.0/140 or 2.0/170 TDI?

I was going the back roads, well anything non motorway (A977 and the A91). I had to join the motorway for a few miles or so sitting at 75mph but pretty much sat at 60mph all the way there. Not much traffic on the roads surprisingly so just sat at a steady pace. Its a 2.0 140ps A3 with the best part of 60k miles on the clock (3 years from new). Great car, just hoping the GTD is as good as I hope it is.

In every aspect but mpg and output (which may be attributable to my choice of fuel as much as needing running in), the GTD is a big jump over the previous gen VAGs - ride/handling/comfort/standard equipment are all excellent.

Assuming you are going through the gears... there are only three factors at play here: power, weight and , as speed increases air resistance (frontal area is the major factor here)... And the weight and frontal area are known or could be calculated... power is the unknown. There is one other unknown... whether your throttle openings amount to the same thing... The only real way to rule that out would have been to run the cars at full throttle...
A well run in one would go a fair way over book output, maybe now they can be accurately limited to book output with a more sophisticated ECU? Did I have a 170TDI putting out about 190PS, or do I have a GTD putting out less than 184PS? Roads were dry, so seemingly no grip issues. Scirocco had 235/18 tyres vs GTD 225/18 tyres, could that be significant if the traction control didn't intervene?
It could be any of the above scenarios (and you'll probably never know unless you could run both cars back to back on a rolling road). The tyres will not make a significant difference assuming their rolling resistance is similar - and increase in section from 225->235 is ~4.5%... another factor could be the mass of the wheel/tyre combo but I suspect there's not a lot in it...
In the end there are too many unknowns to make a judgement on whether (a) there is a significant difference between your Scirocco and your Golf (b) if there is whether it is because your Golf is down on power or not
-
Corgi:
I suspect the use of V-power (which the Scircco was never fed) might be a significant factor. Less potent fuel (V-power ave Cetane = 52, Shell standard ave Cetane = 56) could explain poor performance and poor mpg. I won’t know for a few weeks – probably got about 10 days-worth of V-power left in the tank at the rate I use it. The relative limpness of my GTD in 5th and 6th gear acceleration compared to my Scirocco makes me hopeful that it is the fuel. Another regen today – the car’s fan was deafening when I parked up. 2 people chased me from the works car park to tell me I’d left my car on! Despite the regen, my mpg was not bad for the journey compared to what I have been getting on my commute – an indicated 46.9mpg.
Also, the Scirocco is more Aerodynamic than the Golf, I suspect not massively so, but might make a 1 or 2 mph difference on my roadsign marker test, as might a strong headwind as opposed to no wind or a strong tail wind.

MH - do you reckon that V-Power diesel might be detrimental to efficiency? For gasoline I recall Shell and others promoting improved efficiency for their higher octane "V-power" type products. :undecided:
-
For the diesel version at least, V-power's likely gains are from your car running cleaner because it is a purer fuel. It used to be pure GTL content (apart from the additives, and now it is a blend of oil derived diesel and GTL derived diesel. V-power is less dense than normal diesel, because the GTL derived part has shorter average hydrocarbon chains than the oil derived part. Basically it has less hydrocarbon content and therefore less chemical energy than standard diesel. If it can burn more completely than standard diesel then there could be no disadvantage, but as people running normal aren't being inundated with regens then i'd say standard is combusting just fine in the GTD. Lower Cetane rating with V-power (52) than Shell's standard (56), should mean that standard has a head start in combustion.
I wish i'd used my Chemistry degree and thought it through before I filled up with V-power.
Assuming I do get better performance with standard diesel, I'd say V-power shell is better for cleaning out an older car than keeping a new one running perfectly.
V-power petrol to improve a car optimised to run the higher RON fuels is different, plenty of petrol users will swear by V-power.
-

It might well be more aerodynamic with a smaller frontal area but will that offset the apparent power:weight advantage of the Golf?
I purposely hadn't factored in wind direction and strength, because, again they are unknowns
As I said, I suspect you'll never know whether your Scirocco was a good one and your Golf average...
-
Corgi: my Golf is 10kg heavier than my Scirocco, those 2 extra doors negate the weight savings, not that 10kg is going to do a lot either way. Too many variables - hoping V-power has been the achilles heel to date.

Norbreck21: I put in a lot of thought about some things - that very expensive lump of metal parked outside my house is getting most of my thoughts right now! :grin:

-
I was out on Sunday for a couple of hours with a mix of motorway and a roads and believe it or not the car decided to regen just as I pulled up outside the house and that's using normal shell. I didn't see more than 1regen when I used the vpower diesel but have had three already using normal stuff.

How’s your mpg though on the normal stuff? Better than with V-power I hope.
I do wonder whether V-power has a cleaner burn because there is less combustible product per litre to burn (because it has a lower density), and because of that it doesn’t need a high Cetane number to completely (or nearly completely) combust.
Although saying that, I have had 2 regen attempts recently on 100% V-power, maybe it’s the colder mornings making the car take longer to warm up and work at its most efficient.
Sometimes regens seem to start at the end of a journey for me – quite inconvenient when you pull up and the car is making a racket because the fans are going full tilt to cool the car.
-
I emailed VW to ask what kind of fuel performance I should be expecting for the type of driving I do...
Also speaking to one of the guys at work who said his daughter has a Mk6 GTD and can easy get high 50s on a motorway run.
Given the Mk7 car is boasting economy figures about 10mpg higher then I would expect it to mean the mk7 should be capable of this or it means the figures are absolutely pointless ion every way.
-
I notice on the TV adverts for the new Audi A3 E-tron Sportback (due out Autumn 2014), they have prominent messaging to say that the quoted economy figures are for comparison purposes with other car manufacturers only and standard EU tests may not represent actual driving conditions.
Seems pretty clear to me from a VAG company that we shouldn’t be expecting anywhere near published figures….ever. Anything better than the last gen is to be taken as a bonus it seems.
-
I hoofed it to work today, and despite it being a chilly 6C, I think there might be something in driving the car a little harder to get it warmed up (and more efficient) quicker. Got an indicated 47.2mpg, which is probably still only around 42.5 – 44mpg actual, considering I have the box back on at setting 4. I have recently averaged 42.5mpg actual when I have not been putting my foot down.
-
One of the VW sales guys had his own Scirocco 177 tdi and reckoned it took 3000 miles to eventually loosen up and really get going. Maybe the low friction bearings in the latest VAG engines take more time to bed in...?
That's interesting, my GTD has just reached 3000 miles and it feels much more urgent. I'd previously commented on how it felt a bit flat in 5th and 6th... it's got hugely better recently and now pulls like I'd expect it to.
From new the engine has always been smooth and willing to rev but now it's got the grunt to go with it :smiley:
I had been running BP Ultimate for a few tanks but can't say I noticed an improvement in performance or economy. My previous cars have always run noticeably better on BP Ultimate (albeit with no measurable improvement in economy). I'll probably give it a go again to see if I can notice a difference now.
Economy wise it's been consistent since new (I generally do the same journeys each week) -
449m 47.9mpg (47.9)
462m 48.8mpg (50.4)
502m 49.7mpg (50.6)
433m 47.3mpg (52.6)
423m 47.9mpg (48.7)
509m 48.6mpg (50.9)
The number in () is the indicated MPG whilst the other is actual measured brim-to-brim. Most of my journeys are on the motorway sitting at 75-80mph and some slow city centre traffic.

My Scirocco’s mpg didn’t improve appreciably with time/miles, but it’s output did (a single huge step at 320 miles/500Km and small gradual gains after that). Perhaps I took advantage of the extra go as it developed and negated any mpg gains. My actual mpg has been solidly consistent with my fill ups also - 42.3 to 42.5mpg actual, using Shell V-power. Hoping to see a noticeable improvement when the last of the V-power has run out and I switch to normal Shell. If I see a 10% improvement in my actual mpg then mine will be on a par with yours and just about surpassing my Scirocco (51mpg indicated/46mpg actual – on average).
The TDI-tuning.co.uk box I have fitted at setting 4 of 7 seems to have the GTD at my stock expectations in terms of performance, just about surpassing the Scirocco. Hopefully with regular Shell and a (fingers crossed) 5-10% gain in mpg should come with a corresponding performance increase too.
-
Cheers MH... your Scirocco sounds a bit like my previous Octavia vRS CR... that always had consistent economy from new as well.
I'm still interested in getting the TDI-Tuning box for the increased power rather than any claimed economy improvements. Although as I discovered last night the Bridgestones are rubbish at putting the stock power down in the damp!

They are really bad in the wet. They’re not amazing in the dry either. My dad cannot get GTD his to tramp at all (Dunlops, DSG), but I can get mine to tramp just about in the dry in 1st and in the damp with 1st and 2nd quite easily – traction issues when hoofing it in the damp in 3rd at 65mph. I’m sure 4th /5th /6th won’t be an issue, but that box is going to do nowt for you screaming away from lights if you have Bridgestones on.

I was out on Sunday for a couple of hours with a mix of motorway and a roads and believe it or not the car decided to regen just as I pulled up outside the house and that's using normal shell. I didn't see more than 1regen when I used the vpower diesel but have had three already using normal stuff.
How’s your mpg though on the normal stuff? Better than with V-power I hope.
I do wonder whether V-power has a cleaner burn because there is less combustible product per litre to burn (because it has a lower density), and because of that it doesn’t need a high Cetane number to completely (or nearly completely) combust.
Although saying that, I have had 2 regen attempts recently on 100% V-power, maybe it’s the colder mornings making the car take longer to warm up and work at its most efficient.
Sometimes regens seem to start at the end of a journey for me – quite inconvenient when you pull up and the car is making a racket because the fans are going full tilt to cool the car.
Mind just did its first active regen (that I've noticed) when I got home. Ran for maybe 10 mins and smelt very hot - thought I'd better keep an eye on it to make sure it didn't catch fire :grin:. I'm wondering whether this is something specific to the design of modern VAG diesel PF's, or do other current makes do a similar thing?
-
Speaking of the regens, I know there are 2 types, active and passive. I guess the active one is where the car deliberately raises the temperature of the exhaust gasses, hence probably why the fan runs on after shut off to cool everything down.
In the 1½ months and 1200 miles I've had the car, I've had experience of maybe 3 times of the stop / start deactivating itself and the revs ticking over at around 1000rpm (rather than the usual 800 rpm), and this has always been coming to a stop off a motorway junction after a 70-75mph run ?.
I assume then the car was doing an active regen ? It's just that when ever I have stopped the car, I've never once had the fan running on or any unusual smells (other than when the car was literally brand new and I had that paint burning smell you get with all new cars). On switch off the car is always deathly quiet and smell free. So the question is, are these active regens (or passive), and is it just that by the time I switch the car off the regen has finished (that's why I don't have the fan running on) ?
Is there any other way to tell ?
-
Yesterday's active regen was the first (done 900 miles so far). This week has been all short journeys which might explain it.
I also noticed driving home before it happened that the gear shift indicator was encouraging a lower gear than normal. I think I read somewhere in the manual that is all part of getting the regen cycle to complete quicker. It also mentioned that for auto cars (presumably meaning DSG in auto mode) the car may run at an increased rpm/lower gear ratio to aid the regen cycle. Whether this is all specific to an active regen cycle I'm not sure.
Norbreck - if you've been doing plenty of motorway-type driving that most probably explains why you've yet to experience the joys of an active regen after switch-off.

MH - with all that hoofing I'm not surprised your economy is worse than mine :grin: :grin:
I'm still taking it easy but will start to open it up now with a few miles on.
Mine came with Continentals - never had them before so will be interesting to see how they perform in anger...

Just thought I'd add my experiences. I've been getting high 40s low 50s on a regular basis with supermarket fuel. Decided to give shell a try (non v power) and ever since I've not seen over 43. Going to give it another tank full of shell but not impressed so far.
-
which supermarket fuel were you using kyle? I'm not overly impressed with shell but then again if they've changed to winter diesel then that could be a factor.

Really surprised by standard Shell giving you poor mpg - Esso, Morissons (which I won't touch) and Sainsburys are all cheap near me. My previous TDIs have always preferred Shell to anything else. If I don't get any appreciable power gains on standard diesel then i'll be keeping my TDI-tuning.co.uk box because right now (still running out the Shell V-power), setting 4 of 7 just about outdoes the Scirocco (traction permitting on the sh!tty Bridgestones) - exactly what I was expecting for the GTD before the big miles roll on.

If you've just started a regen and the car hasn't got that hot when you finish your journey then you'll get no fan. If it's maxed out on temp then the fan will need to kick in. You've probably had a few regens that have happened passively and finished before you finished your journey then cooled down enough for the fan not to kick in. You'll notice them by higher idling rpm (1000 instead of 800) if you're stopped at lights/roundabout etc and your gear change prompts encouraging a lower than normal gear e.g. holding onto 3rd to 30mph, holding onto 4th to 38mph.

Thanks MH - that fits. Also the auto stop has been blocked a few times, presumably for the same reason. Annoying that the manual is completely silent on all this :angry:
-
SkineeD: Yep, auto stop disabled by the car definitely means a regen is happening that the car doesn't want to disrupt.

It was actually Morrisons and ASDA that are giving me the better figures. As I said I'll give Shell another tank or so and see if it improves.

A wee light on the dash when the regen is on would be advantageous for me.
My commute is mostly b roads and dual carriageway to work and my first stop is 100 yards from work.
So on the way back home I rarely get to stop at all apart from when I pull up on my drive and a few times its been doing a regen. If it had a light on the dash I would have drove another couple of miles until the regen was finished rather than have the fans go hell for leather for a full 15 minutes while parked on my drive and then have to do the whole thing over again the next time I get into the car!!
-
This is currently being discussed over at the Motor Talk.de forums, to see if a warning can be shown on the MFD vis VCDS.
I'll keep an eye on it and if possible I'll let you all know (not sure currently though if it is even possible) ?

Sorry to appear thick - but what's a Regen ?

Sorry to appear thick - but what's a Regen ?
The car's way of burning off the soot that the DPF collects, before the DPF fills up and clogs. Active and passive regens. Passive if your driving style and journey allows the exhaust system to get up to temp on it's own, active if the car needs to artificially create the high exhaust temp by sending some fuel in there to combust (makes the car a bit thirsty on an active regen).
-
Great - thanks. Looks like it'll be well into next year before i get to experience them for myself.
-
On the topic of 'regens', I had no idea about them either.
This technical explanation is very thorough - it might be a little out of date now though:
http://uk-mkivs.net/forums/t/343695.aspx
In particular, the bit on that link about what happens if you keep interrupting these regens is a little worrying! They also recommend people don't use a diesel on small islands!
We use the car mainly for out-of-town journeys of an hour or more, so we probably would be good candidates for a diesel car, but still...

Thanks, that's interesting. As the active regen is evidently helping to avoid the risk of damage to the DPF I'll be less annoyed now when it's sat doing one for 15 mins on the driveway :smiley:

I have high hopes for my mpg having just ditched the Shell V-power and filled up on Esso. The 4 mile drive home from the petrol station (on the way home) after fill-up saw the car being noticeably more spritely.
-
First commute with Esso today and the car is noticeably perkier than with V-power. Less throttle needed to do anything. Indicated 47.2mpg at 4C ambient temp (likely actual 44.5 - 45mpg), which was the best I achieved if I drove like a nun with V-power at 12C ambient temp a few weeks ago. Much better. If I can achieve 45mpg actual on my commute in winter then I will have bettered my Scirocco (just).

Good news MH. Who'd have thought that a "premium" fuel would actually work out worse mpg - shocking...
-
Quick update from me, MPG seems to of improved in the second half of the Shell tank. Still not getting any better MPG than the supermarket fuel but I'm willing to give it another tank or so.
Think the length of journey really does affect MPG. On my 35 mile trip it's easy to get around 48-50 with good acceleration and cursing between 70/80 but anything lower mileage wise and I struggle to see over 45.
-
Still slightly concerned about my town commute mpg. I have altered my route so there is limited stop start (I'd say 3). But still struggling to get above 40mpg. Motorway wise I easily get 48/52.
-
The biggest difference I have seen with this and my other VWs is that even though the water temp gets up to normal quicker than in previous VW TDIs that I have had, the oil temp is a little slower to get to temp, which will have big mpg (and soot build up for regen) consequences on shorter journeys.
On the drive home from Newcastle last night (8 mile journey at 8:30pm, very clear roads, a few miles of 30/40mph driving, 5 miles of 70/80mph driving and then another mile of 30/40mph driving), the car managed 48mpg despite a regen going on which left the fans blaring for a good 5 mins after I got home. This morning the car only managed 43mpg getting into work. It was a smidge colder than yesterday (2C), but mpg seemed to climb quite quickly to 41mpg and then it crept up to 43. I’m wondering whether a lot of power generated by the engine in coming to work was used in charging the battery after the fan cooling following regen had probably used quite a bit of the battery’s capacity, hammering my mpg.
First stall ever on my car today, handy that the car restarts itself as soon as you dip your clutch.
-
I have put in a request/complaint to Volkswagen and asked them what range of MPG should be achievable in real world driving scenarios..
Not sure how they would answer - the woman kept asking me to take the car to a retailer so that it could get checked... I don't think there is any fault with it - just would like VW to provide an expected range of what can be achieved in real driving..
Would be very disappointing if the engineers could not provide some basic info on a basic operational parameter of something they have designed and extensively tested.
My conclusion is on this car you are going to be hitting max 45-50 mpg on motor way runs/mixed driving and between 35-45 round the town and in traffic...
Considerably less than the advertised....
-
Advertised..?
VW are required to quote the official figures... It is widely known that the official figures are most likely I obtainable in real life... I've posted the AA report on this where they said to expect significantly worse MPG than the official tests would indicate - work on 30% less any you're likely to be pleasantly surprised... The same goes for most other (especially) diesel hatches... My g/f's BMW 120d averages about 48-49 overall...
It's the test that's unrepresentative... Because of the conditions and the number of stops etc...
I would expect an average of between 45 and 55 in general driving depending on driving style and mix of driving...
-
The issue is that they've recently moved the goalposts. They're still misadvertising when they say the MK7 Golf is 20% more efficient that it's predecessor. That is a boast they have made in the brochure and in adverts. That's complete bullsh!t. If they applied the current tests to the MK6 GTD or 170TDI Scirocco/Passat, I very much doubt there'd be more than 5% in it between them and the MK7 GTD, or between the 210PS 2.0TSI MK6 GTI/Scirocco and the 220PS 2.0TSI MK7 GTI.
I'm now expecting a true 40mpg on my commute in the winter and 45mpg in the summer. For longer journeys maybe 48mpg in the winter and 55mpg in the Summer. These figs are worse than my Scirocco by about 5%.
According to brochure information (i''d consider that advertisement), they sold these 20% savings on low friction bearings, faster engine warm up times, standard start-stop and brake energy recuperation tech as well as weight savings of up to 100kg(the weight savings have proved pretty insignificant on any model that retained the multilink rear suspension). Most of those savings have been "achieved" with a different testing regime. We have been sold a lie as far as fuel economy is concerned. Those technical advances appear to have had little impact to improved fuel economy in real world situations.
-
Whilst I 100% agree with you MH, that VW's advertising was at best "creative" and at worst a damn right lie, TBH, I came into the GTD with my eyes wide open. Despite the lofty claims made for over 60mpg combined and nearly 70mpg extra urban (DSG Model), I never for one second ever thought I would get anywhere near that.
My yardstick so to speak was my previous 140 CR Scirocco (like you using your 170 CR Scirocco). Whilst it seems it wasn't as frugal as yours (but that could just be down to my journeys as my trip to work is only 10 miles ish), it averaged about 46mpg over it's 20k lifetime. I always said if the GTD could get that (or very near it), I would be pleased, especially as it's much more powerful than the older car. Well, over the first 1300 miles, the MFD is showing 46.2 for the lifetime (which equates to a real average of 45.3 working it out brim to brim), which is pretty close. Bearing in mind the car is still running in and feels tight, and my Scirocco did improve by 3-4 mpg once it went over about 5-6k miles.
The way I look at is that for a car with 184ps, capable of over 140mph and 0-60 in around 7 seconds, to get that and get mid forties MPG (though obviously not at the same time) is still doing pretty well. The GTI boys were promised mid forties and most of them are struggling to crack 30-35mpg, and in the real world (and I'm going to be shot for saying this), if you are not doing traffic light standing 0-60 drags, the performance difference between a GTI and GTD isn't that huge.
We could analyse this all day - is it tyres, drag coefficient, engine map, the fuel type etc, but my guess is that the 170 CR in the Rocco and the Passat probably over specified in HP, whereas the 184 CR in the GTD, probably only just meets those figures (of course I could be totally wrong :grin:), and is probably more to do with new Euro Emission Laws and the newer cars needing to be greener and emit less CO2 etc. I'd probably bet that if you had a stock 170CR Scirocco and a Stock 184ps GTD on an identical rolling road, they would produce very similar power figures ?
-
If you look at this: http://www.honestjohn.co.uk/realmpg/volkswagen (http://www.honestjohn.co.uk/realmpg/volkswagen) it would suggest that VW are better than the industry average, BMW, for example, according to this are significantly worse... Is it a coincidence that in sectors of the market where fuel consumption would be a significant factor in the buying decision that the results of normal driving offers fuel consumption farthest away from the official figures?
As I said previously, the issue is with the validity of the tests. The manufacturers use them in advertisements because that is the only official comparison available.
Make the official test more relevant and the issue goes away. At the moment manufacturers are, at least, designing and building cars to maximise their performance in tests for emissions and fuel consumption (in certain sectors of the market)...

Norbreck 21a:
Power – there’s another way they may have moved the goalposts. Now I’m on regular Diesel, my GTD has picked up on power and responsiveness. I’m no better off on mpg right now for my commute to work (but I am on my commute home) – I suspect that’s because ambient temp at 7am locally (when I am on my way to work) has dropped from 9 - 10C to 2 - 4C in the space of a week. I’d now say my GTD is around the same power as my Scirocco (but with crap grip due to a poor choice of OEM tyres affecting my lower end performance potential) and a smidge thirstier. For 15PS more (on paper) and slightly worse fuel economy right now, my biggest benefit in the car change is a nicer interior, the feeling that the GTD is a little better put together (smaller panels gaps, nicer interior materials etc) and some significant extra equipment. Oh, and a £20 tax disc in future – at least they’re robbing the treasury as well as us.
I honestly thought I would see half of the 20% gains boasted in the real world, I didn’t expect to get none of them. It meets or exceeds all my other expectations, especially ride quality improvement.
-
Well I would think more of us bought a GTD for mpg considerations than bought a GTI, yet the reality to official disparity figures are pretty much the same for both – around 30%. I think the disparity is pretty big across the board. Every car manufacturer is trying to outdo the next one – on paper at least. That’s usually where the buying decision is made on a new car, poring over the specs. Yes have a test drive, the car drives great, gave it a bit of welly, but you don’t really get any gauge of mpg on a test drive.
The current tests are a joke, they don’t represent normal driving at all. I’m surprised the government and/or the EU haven’t jumped all over this mass deception.
-
38.90 mpg on first fill and 230 miles - although I'm not sure that the dealer tank full was right to the brim and with the new filler its not so easy to ensure that if you stop when the pump clicks off initially. Plus my longest journeys have only been 20 miles and the weather is colder. Hopefully I will improve upon this at the next fill!

So we agree, violently :smiley:
In reality, when I was researching cars I look not at the official figures but look for what is likely to be achievable as, for me at least, it is well know that the official figures are not-representative... it a bigger issue if you compare your current car's real world fuel consumption with the official figures of a new one...
In the end the official figures are only useful for comparison... and even then only in general terms and need to be correlated with some other data. I expect my Golf (when it arrives) will be a little more economical than my g/f's 120d... Official (67.3 v 65.7)... I would correlate that with the emissions (109 v 118 iirc). With the same driving profile I would expect to see the mpg on my Golf at very high 40's to low 50's as the g/f's 1er is averaging about 48 (indicated)...

I had my car in for a knocking sound to the rear and I had em look at the economy as it was on average 13 mpg less than the quoted. The 'master technician' looked at it and said the from start mpg reading shouldn't be hitting the higher end of the quoted range but no technical explanation. I thought f*ck this I will leave it till 5k miles and see.
-
Interestingly today, I had to nip somewhere at lunch (see my other thread for the scratch that occurred as a result). 18 miles each way of motorway plus a few miles of A roads etc, and because I was in a hurry, decided to not cosset the car so 80-85mph all the way and some heavy acceleration to boot - not in the least bit concerned over economy.
Only checked the MPG on my return (expecting to see 35 or something) and was very surprised to see 53.1mpg for the 36 miles trap at an average of 58mph. Not too shabby, maybe I need to drive it harder more often ?
-
On a motorway stretch after shorter journeys, I would definitely say drive it a bit harder because you're more likely to clear your DPF out, and the car is warmer for a larger proportion of the journey on a longer run.

If you place 50mpg as an acceptable level then drive it however you wish

Just under 45mpg (indicated) on a return trip to the Metrocentre (31 miles) on uncluttered roads and felt a little low on power, back down to the levels experienced with V-power. It has been poor for a few days now with a regen going on for my last few commutes, but not today. Absolutely sh!te - an easy 53mpg journey in my Scirocco. My tyre pressures are spot on and i've checked the air filter to make sure it hasn't been put in backwards or something daft like that. I have done about 1500 miles now.
Going to book an appointment with the dealership to get them to look at my low mpg and power, sort the dash rattle/buzz @1500rpm and sort my squeaky front drivers side shock out. I'm sure there's something else minor to sort out too, but can't think what it is. When I had my 170TDI PD MK5 Golf, that was plagued with DPF regens and low mpg until they gave it an official service remap that sorted everything, Maybe more of the same is required.
If i'd have known I would be looking at the realms of 40-43mpg (actual) for a GTD, I'd have got a GTI and aimed at a realistic 35mpg. If the situation doesn't improve, this will be the last TDI I buy.

Going to book an appointment with the dealership to get them to look at my low mpg and power, sort the dash rattle/buzz @1500rpm and sort my squeaky front drivers side shock out. I'm sure there's something else minor to sort out too, but can't think what it is. When I had my 170TDI PD MK5 Golf, that was plagued with DPF regens and low mpg until they gave it an official service remap that sorted everything, Maybe more of the same is required.
If i'd have known I would be looking at the realms of 40-43mpg (actual) for a GTD, I'd have got a GTI and aimed at a realistic 35mpg. If the situation doesn't improve, this will be the last TDI I buy.
How many miles has the car done?
-
2013GTI: 1500 miles. Some might say "give it to 5000", which is probably what the dealership will say, but i've never had appreciable mpg gains on my previous 6 TDIs bought from new, certainly not 10% more than where i'm at now, to put me where I realistically thought I would be.
I wonder whether the car's ECU is set up for a cold start protection routine, where it limits output for the first few minutes of operation, and perhaps mine is staying on. I really feel that something isn't right with the car when low mpg is going hand-in-hand with slightly lower than expected output.
Will be getting it booked in. The other thing that needs sorting is recalibration of the sensors involved with the handbrake system after I had a failure that the MFD flagged. The autohold has switched itself off a few times after that.

MPG is such a unpredictable aspect of a car but I would say it will improve and that 1500 miles is way too early.
My Polo Bluemotion is now retuning me 10mpg more than when it had delivery mileage on it. It was around 20k miles before it really opened up.
Get the dealer to give it the once over just in case there is something amiss.
-
Will it average 50mpg? Because I would be happy with that.
-
I've only done 300 miles so far, averaging 38mpg since the beginning. I was tinkering with some settings and I noticed that the air con profile was set to run at medium, changed that to light and mpg has improved doing the same runs the last few days. I do wonder if the mk7 is like the mk1 focus in that the air con is assisting demisting etc even though the indicator light isn't lit.

I thought you might be onto something there. I have (so far) not really used the aircon. It is in Eco on my driver profile (individual - everything on Sport except aircon. The aircon itself is switched off and I have experienced a few bits of mist on the inside of the windscreen which suggests to me that my aircon isn't on when I think it isn't.
My GTD is massively thirsty above 60mph compared to my Scirocco. There seems to be a much bigger fuel penalty for choosing a 70 - 80mph cruising speed than the last gen, or maybe my Scirocco was so much more aerodynamic than the MK7 Golf.
-
I know its virtually the same car, but I've just driven 313 miles (INCLUDING 55 miles static), and our vRS produced a calculated 39.2MPG..

That's very poor - especially if 55 miles of it was done on a Dyno/rolling road with no air resistance to consider (I think that's what you meant by static?). Is that the first 313 miles or just a 313 miles on a stint?
*update* I suppose that mpg is relative to what you were doing. If I were doing mixed driving including motorway cruising at 80mph, i'd be hoping for about 45mpg on the longer journeys even with my poor mpg.

My last 500 miles gave 54.1 mpg indicated and 53.1 actual. Nearly 1500 miles total now. Mix of cross country, a bit of motorway at 70 and numerous short journies <10 miles. Only occasional hoofing though to be fair. At 70 I reckon I'm averaging 50 or so mpg but will check on a longer motorway trip this week. Aircon profile is always on econ; climate is on auto but with A/C off. Have used the demister a few times.
-
Skinee D: That's what I thought i'd be getting! I must admit that given the opportunity (traffic density), i'd rather be cruising at 80mph for maybe 50mpg average.
My aircon is set to eco, but not being used. So far my MK7 is less prone to misting up than the Scirocco was, so i've not had to rely on the aircon at all.

I'll pay closer attention to the motorway mpg this week and feed back. Hope you get a result from the dealer when you get yours checked out.

Might be without my car for a few days - i've got a list with 5 points of interest.
When my 170TDI PD Golf GT Sport (57 plate) had DPF and mpg issues, they had the injectors out, found no leaks, and replaced the cylinder head because there was a tiny burr seen. They cleared out the DPF and sent me on my way. A week later the same issues occurred. They consulted Germany and applied a service remap - problem solved, although that car seemed to take an extra 2 seconds to turn over before firing up after they'd replaced the cylinder head.

I was pleased with 40mpg, that was using aircon and using my right foot in both directions, as well as the 55 miles of static use.
I normally don't look at the mpg, but thought I'd check it on this occasion and as I've said I was pleased with the results

Can you define use of the right foot or don't want to incriminate yourself? :whistle: My dad's mpg is quite impressive considering he likes to maintain 90mph on the motorway.

Andrew - thanks for all the feedback on your tuning developments - very interesting. If you do get chance some time, it would be very interesting to see how the Skoda's mpg readout compares to actual. My mileometer is right on vs GPS; so far indicated mpg has been 2 mpg optimistic on average.
-
I reset the trip after refilling on Saturday evening, since then I've commuted to and from work,mwhich is 4 miles, and took the kids to school which is another 8 miles.
We've also been road testing the car again today, so I'm probably the worst person to ask about fuel..
-
Those short journeys aren’t going to help the mpg – how are you finding DPF regens? Those kill mpg and I seem to be getting more than my fair share (which I think is part of my problem) compared to the Scirocco. I’m not finding the 184PS Diesel engine any quicker to warm up than the 170TDI CR unit, despite VW’s claims that it warms up quicker and therefore helps fuel economy. My water gets up to temp quicker, but the oil takes longer (compared to my Scirocco).
My mpg and general liveliness of the engine were uncharacteristically good this morning. 47.5mpg (indicated) for my commute, maybe down to the abnormally warm weather this morning at 7am (8.5C) or maybe the car has finished its recent regens. Bad timing for my warranty inspection – they may not find anything wrong with it!

And it is water temperature that counts. I don't believe that the ECU takes a feed from oil temperature so once the water reaches a certain temperature the ECU can move to normal running from cold start.
In reality it doesn't take much of a rise in oil temperature to reduce its viscosity from cold - that being said I still keep the revs low and am gentle with the throttle until I see the engine oil pressure settle own on my 911, for example. Oil temperature takes much longer than the water temperature to reach normal running temperature; however, it doesn't need to reach that temperature to be providing protection...

Just a bit of an update on my MPG. Sacked Shell off as their MPG was atrocious. Filled up with Tesco diesel and I've not seen better! Comfortably getting 48-50 and on the past couple of trips to work been getting 54mpg with an average speed (according to the trip) of 58.
Just tricked over to 3000 miles

Fear not... it will get better.... :wink:

I have put in a query to VW about my car - struggling to get 50mpg on a run despite driving like a nun... I dont think there is a fault but wanted them to admit this..
I have asked if this is normal and they say it is impossible to tell. If I have any concerns to take it to the dealers for examination.
Very poor response, I can understand why they don't want to commit to other MPG figures but surely they should be able to give a range of figures which would be considered normal..
Such an important function of a vehicle isnt just guess work and change but carefully engineered.

Struggling to get 50? Most here aren’t getting that. I’ve had my car in for other warranty issues and it is going back tomorrow. Initially the technician took one look at the long term mpg and said “it’s over 40mpg, nothing obviously wrong” That’s all they looked at. Had a 10 min conversation about how my previous car did much better than this, how it feels down on power and DPF regens are more frequent etc and he said he’d have a dig around for any potential issues beyond what the computer would potentially flag up as possible faults/outstanding recalls etc when my VIN number is inputted. It is back in tomorrow for finishing off (awaiting parts). If he’s come up with anything in the meantime I’ll let you know.
Sometimes, driving like a nun with a DPF equipped car isn’t the thing to do. Do you have a decent run on your normal commute to keep it relatively clear? Do you experience any active regens (car idles at 1000rpm instead of 800, gear change indicator prompts you to change down to a lower gear at a given speed than would be normal, stop start won’t work etc)? If you’re sitting at 70mph on the motorway for 2/3 of your journeys then 50mpg isn’t too bad. What fuel are you using? V-power was crap for my mpg and the VW technician suggested BP isn’t doing much for some people (either he’s just making conversation or he’s had others come in for poor mpg). He also told me that VW work on a review basis for an issue they’re not aware of. If enough people complain officially through the dealerships they will look into the issue and devise a fix if they find fault themselves.

I, obviously, can't comment on the GTD fuel consumption as mine won't arrive for another 3 weeks or so but the experience we have with my g/fs new 120d M-Sport.
I've done a few runs in the 120d now and on the motorway at about 75 it averages 50mpg plus or minus 1 or 2 the official figures are 65.7 (combined) so about 23% worse than the official and it is on about 2500 miles now.
If I can get my GTD to average around 50mpg, I'll be happy... I never put much store in the official figures... to be honest the big driver for me to pick the GTD was its low emissions (109g/km) which makes it quite tax efficient relative to the GTI, the 120d etc.
I did find that my previous 123d improved fuel consumption with mileage... I bought an ex-demonstrator with about 3K miles on it and could barely average 40mpg... by the time I sold it I was averaging close to 45mpg. I suspect that was a combination of the car and me adapting my driving style...
As for the power side. I know you have sign speed test, Monkeyhanger, but is it really appreciably slower than your Scirocco? The significantly improved refinement may make it feel slower but is it really? As you've stated before they are about the same weight so the Golf should be slightly quicker...

It’s not the most scientific test I know, but have done it a fair few times (all in the dry) but what my GTD can achieve falls in the middle of my old 140TDI CR Scirocco and the 170TDI CR Scirocco. Traction (due to the Bridgestones) doesn’t seem to be a factor, I’m doing 20mph in 2nd when I bear left onto the coast road and put my foot down. Sometimes what the dials are doing does surprise you (due to the extra refinement), but in 5th and 6th pull between 60 and 80mph, my GTD seems to have noticeably less clout than my 170TDI Scirocco. That is where the most noticeable difference is for me.
-
Is the GTD longer geared?
-
Is the GTD longer geared?
The gear change prompts when driving economically seem to occur around the same point as on my Scirocco e.g 3rd from 20-25mph, 4th from 25-30mph, 5th from 30-40mph and 40+ for 6th. 80mph is 2200rpm, same as on the Scirocco. If there are any gearing differences, they are tiny.
I actually had my best run ever today - 49.7mpg on a 37 mile run on moderately busy roads with ave speed of 27mph. It just refused to crack 50mpg. The last few days have been good on the juice (apart from the 8 miles Benfield ran with the car).
My dad is up for a visit next weekend - i'll have a go in his car and see if his is quicker than mine. With the GTD it seems far more important to be hitting the torque band just right to get anything out of 5th and 6th.
Hoping the VW tech will have uncovered something to try tomorrow when I get my suspension mount bearing sorted out.
-
MH you should give Tesco fuel a try mate. I'm loving my MPG on it with a big difference to normal shell fuel. This morning it was a little colder but still managed to hit 48mpg. On mg way home tonight with a lot of traffic and 8 degrees temp, hit 50mpg.

Is Tesco fuel Esso fuel? There are a lot of Tesco Express/Esso garages around me, but nearest proper Tesco garage is Kingston Park (not too far from work, but usually 3p/L dearer than my local Esso).
How long is your commute?

Commute is 35 miles each way mate. A182 (30/40/60) and then A19 (65-75). I'd say I'm fairly aggressive in acceleration too. Addicted to the torque haha.
Not sure if Tesco does use Esso or not but I'm very impressed.
-
Got my best MPG so far yesterday. Heading back from Glasgow to Edin. About 59 miles. Trip computer showed 53.3 mpg. On the way home from work today which is an 11 mile trip I also hit 52mpg. Think the warmer weather maybe helping. Yesterday car reported it as 7 degrees and today was 10.5. Just using bog standard Tesco fuel at the moment but happy with these results. Coming up to 700 miles in total so far so hopefully things will just get better.
-
Right it's time to dust off the Clubcard then :wink:.
My long term is 54 (indicated) at 1800m having used Sainsbury, Shell then Esso. The Shell tank dropped a couple or so mpg that I put down (maybe wrongly) to more short journies. Last refil on Esso gave 52.5 actual.
I anticipate a drop now with the colder weather as my regular commute is only 6m each way - currently it indicates around 48 in the early morning and 50 going home pm (a bit less if any crawling traffic though). Also starting to get some VFM (remember Patrick Mower? :grin:) out of the torque now which must come at a price.
Will definitely give Tesco a go though - hopefully their variety down south isn't inferior...
(Sorry, couldn't resist...quality in perspective :wink:)

Well my hopes for something getting changed while my car was in for other warranty work were dashed this morning. Drove my wife to work as she's doing some overtime. 8am, 9C ambient temp, empty roads. It's 9 miles each way, with miles 2 to 7 having the opportunity to cruise at 80mph. 40mph the rest of it. 42mpg there and I did 70 on the way back. 18 mile overall journey, 45.5mpg indicated. An easy 52mpg in the Scirocco. Doing 60+mpg seems to kill mpg in my GTD.
Will try my next tank on Tesco.
-
All my journeys have been done with cruise set at 75mph. At 60mph you would expect better. The odd thing is I am not driving like daisy and am putting the foot down on occasion. This is when I would expect a poor MPG but get a pleasant surprise when I check at end of trip. Maybe we are looking into this in too much detail at the moment as the cars have hardly been broken in yet.

Sorry to the hear that MH (but good to see you got your susp noise fixed at least :smiley:).
Just wondering - when you're on a steady stretch of 40 mph are you generally using 6th where possible? I usually do and the specific mpg readout easily runs into high numbers (60+). I'm now thinking maybe this is no longer such a good idea on modern diesels in case it gives rise to more frequent regens, which I'm guessing it might.
I should have added that the max speed usually reached on my commute is only 60, to put it in perspective.

I should have added that the max speed usually reached on my commute is only 60, to put it in perspective.
Yes, a maintained 40mph is in 6th, and a maintained 32mph is usually in 5th. About 60% of my 12 mile commute is between 30 and 40 mph, with the other 40% being at between 60 and 80mph (depending on traffic volume). I spend 90% of my journey in 5th or 6th. My mpg on the journey takes far longer to creep up at any given stage than it did in the Scirocco. It just consistently seems 10% worse at every stage. In my journey I used to get up to 40mpg within 3 miles of my journey start and creep up to 50. Now it's quickly up to 35mpg and creeping up to 45mpg (sometimes 47).
The regen regime definitely seems to have changed on the current MK7 engines - little and often, which probably means that regens are hindering your economy more of the time unless you are on a long motorway journey.
-
Have 656 Miles on clock now and just starting to feel a little looser - Perfect motorway cruiser with the DCC and heightened refinement over my previous Audi A3 and with an instant high gear kick when need it.
2 long runs this week in comfort.
1. 191 miles - average 48 mph - 52.3 mpg (40 miles of mixed A/B rest motorway with some delays)
2. 180 miles - average 56mpg - 48.3 mpg (About same as above in road types but no delays and was able to stretch it out some more)
Given not run in yet and mixing driving still I am very happy with these figures as was getting 50 mpg on a steady run with Audi A3 and that had to have a few miles under belt to get that, so expect them GTD figures to get better and even on a local 30 mile run today got to 43mpg.
Also note that for these back to back journeys I did not have to refuel :smiley:
Used Supermarket Diesel on first tank and just put V Power in and with only reason to put in some good quality cleaning products through early, though imagine for most part will place normal diesel in from nearest garage as always done.
It is fast, refined and economical :smiley:
-
2nd fill up @ 537 miles = 40.98 for the last 250 miles, which is not brilliant considering I had 2 x 80 mile runs, although given not on motorways. My Mk6 GTD was in the 43's at first, so the Mk7 is definately lagging behind in mpg. As some have said seems that the regens are more prevalent!
-
Just done over 700 miles in three weeks, first tank was averaging 38mpg, this was mostly commuting, 35 miles round trip with a couple of longer runs as well. Went on a 260 mile round trip and the mpg improved to 43mpg on the way down, decided to hit the eco button and it went up to 49mpg after that.
I have changed the tyres though, same width but smaller wheel so I reckon the only advantage I'm getting from that is a lower rolling resistance from the Vredestein Wintracs over the Continentals that came with the car.
-
I had to make trip back through to Glasgow again this morning (approx 60 miles). Only hit 44mpg. The trip back later in the evening got me 52mpg. I thought outside temp may be having an impact but it was 5.5 degs this morning and 3.5 degs on the way back this evening.
Looks like there is as much logic to this as there is to the VW ordering process :laugh:
-
Don't forget that the wind direction has a huge effect.
If the wind is 15mph, then the difference between heading into it and driving with the wind is a full 30mph.
Wind resistance is one of the most important factors in fuel consumption once you get up to cruising speeds, so if you're looking at fuel consumption, it always pays to count the accumulated consumption over days or weeks rather than looking at the difference between individual journeys.
In my gti mk5 edition 30 (which ordinarily manages about 32-35mpg on long journeys), I managed 44mpg the other day, but that was with the help of a rather large storm wafting me along!
-
MPG is truly awful in this car!!!!! 60...lol absolute sh!te. I have been ragging mine a bit too be fair as well as the conservative approach. But I have been as low as 18mpg (of which I either thought A) I have a hole in the fuel tank and B) I should have got a bloody GTI at this rate. I am generally around the low 30s...and for a diesel that's a joke. around 350-375 miles for a tank by the looks of it
-
are all the figures being posted here the read-out value or from the maths done at fill up? just saying this as is there a chance that the read-out is iffy? (Chances are low that they are so far out, but you never know) - also... i'm sure you can tell by the amount of fill-ups? ;)

18??? Were you driving with the handbrake on? I would have to try pretty hard to get as low as that in my 911 on the road... I have averaged almost 26mpg in that and only once seen less than 20 on a tank full of petrol and that was caning it around the Alps...

That does not sound a healthy car mate. I'd need to be towing a caravan up a perpetual hill to get those numbers... Seriously, have you formally complained and had the car properly investigated yet?

MPG is truly awful in this car!!!!! 60...lol absolute sh!te. I have been ragging mine a bit too be fair as well as the conservative approach.

Its now at 32...still pretty sh!t. I drove my a3 like i stole it pretty much and still managed mid 40s.
18 was round the town and still giving it a fair bit of acceleration. it was stuck at that for a day. and no...handbrake wasnt on lol. Car performs great but i just cant see how 60, let alone 50 is possible
-
Well got I 56mpg on the way home from work tonight, but I wasn't driving it like I stole it, but then wasn't driving like miss daisy either. So it can be done.

Seriously, I get better than 18mpg around town in my 911 (more like 20-22)... 18 mpg on the road... I was trying quite hard driving over Petit Saint Bernard...
If your gag old mpg is really as bad as you say then I would go and get it checked out...
-
Abysmal 39mpg on a 40 mile round trip, mainly motorway (80mph) speeds with 4 adults and a bit of shopping in the car. First half of the journey I was aware of a DPF regen going on with start/stop auto-disabled and idling at 1000rpm. Was in Normal mode, been using Sport prior to the other day. Normal seems thirstier. Sport seems livelier in the lower end and normal seems to have more clout in the overtaking range.
-
Wow...weird MPGs for sure. I've now covered just shy of 5000 miles...long term is 47.9 but I have noticed a decrease since 2 recent 150 mile trips up and down the M5/M6
-
Having lurked on here for months, finally thought I'd add my experiences of a GTD for what they're worth.
I've done 1600 miles in my 5dr GTD manual including motorway,around town and I live in a very hilly area. Tried all the modes, eco is fine on motorways but awfully "flat" elsewhere and sport is a bit noisy. Overall since start the computer says 51mpg and it works out about 50mpg fill to fill. Managed an indicated 67MPG on a 30 mile trip on the M6 last weekend in eco mode. I compete in motorsport events so am not a Sunday Driver.
My last car was a Touran 2.0TDI and that averaged 48mpg over 84,000 miles also on Asda diesel as V Power or BP Ultimate killed the economy.
Only get occasional regens with the GTD and never had the fan running after turning off the engine.
Very happy with the performance, it's as quick as I need it to be and can't see why anyone driving this on the road would need a remap/tuning box etc. If it's too slow go and buy an Evo 6 and use the money you'd saved to pay for the fuel :smiley:
I'm really pleased with the GTD, bought it as a demo with 200 miles on the clock, no faults, no rattles, no swirls, in the colour I wanted, with options I didn't pay for and much cheaper than a new one, but still had to wait 3 months for the dealer to release it :grin:
Oh, my car has the dreaded Bridgestones, but with all the electronic assitance and sensitive use of the throttle I can't say anything negativeabout them, did 200 miles last night on slippy salted roads with no issues.
The only criticism I have is that the genuine rubber mat in the front drivers side doesn't cover enough of the carpet.
If you're thinking about getting a GTD, have an extended test drive and make a decision based on that. All round the best car I've ever driven.
-
There is something that would be really interesting to do, to see if there is any correlation between fuel used and what gearbox you have. If we could get a table knocked up that said the fuel you were using (Tescos, Esso, Shell etc), your long-term mpg figure (MFD value – let’s assume it is consistently 5% optimistic), maybe add in approximate miles done (to the nearest 100 miles), so we can see if higher mileage examples are giving better mpg and whether you are manual or DSG (as some DSGers, if not most, seem to be getting cracking mpg).
This morning my commute bounced back to 45mpg (in “Normal”, which seems to be thirstier than Sport for me). So it would seem that my car does and indicated 45-47mpg when it’s not regenning the DPF and 40-42 when it is.
-
MH you seem to have an awfull lot more regens than I seem to have. Don't think I've had one on a journey that has been over 25 miles. My MPG keeps getting better and better too. Last tank on Asda fuel saw me hit 53MPG according to the MFD for the tank.
-
Something I noticed this morning whilst driving to work that may (or may not) be related. As it was bloody freezing this morning (-3 deg C), I set the climate temperature on 29 deg (normally it sits at 23 deg).
About 2 miles into my journey I noticed was I thought was a regen (idling at 1000 rpm and start / stop deactivated). As it was greeting warm air inside, whilst i was stationary at the lights I turned my temperature down to 24 deg and instantly the revs dropped to about 750rpm then the engine cut and start stop reactivated. A little unsure what had happened, I turn the temperature back up, and immediately the car re-started - turned it down and a few seconds later it stopped.
I'm now wondering if some of the "regens" I've been seeing on the way to work were not in fact regens but just the 1KW PET electric heater switched on at higher temperature settings to warm the coolant up faster. This must have a big load on the electrical system hence the system raises the revs and cuts the start / stop function ?
As it's going to be freezing again tomorrow, I'll try it again just to see if it was a fluke ?
-
I haven't been whacking up the heat. Coldest i've seen since owning the car was +2C (as it was this morning). I'm pretty resilient to the cold, being from the north sea coast (typical of the Geordies you see out in short sleeve shirts drinking in December! :whistle:). I don't put the heating on, it's set to "low" (and even when I put the heating on, 16C is enough for me) until the car is well on it's way to warming up (water at 90C and oil at 70C).
Don't think my "regens" are down to the auxillary heater doing its stuff because I don't have the blower pushing out warm heat until the car's engine is almost warm.
I will have to give Asda diesel a go next time I fill up, as per Kyle's recommendations - I would love to just crack 50mpg on my commute. Car is going back into Benfield tomorrow ( I would go to Pulman but it is just too far for convenience from mine - the "we'll collect your car" service has not been available the last 2 times of asking) for another look at the handbrake. After those Benfield monkeys just cleared the fault codes and didn't actually fix it, the fault happened again last week. Since then my auto hold and handbrake have switched off a few times mid journey (usually one or the otherr, not both at once, and no further notifications that they have switched off.
Further experimentation with "normal" has me convinced it is thirstier than "Sport". It seems to be the better all around driving experience - less power at the low end (giving any more just contributes to tramping) and more potent in the overtaking (40-80mph) range.
For the regens i'm getting, i'm convinced my car is not running at it's best - I never had a single active regen on my last Scirocco, everything was happening passively and my car usage hasn't changed since getting the GTD.
-
Getting involved in the MPG debate again. I'm with virginvwman. I don't drive it like I stole it but around round is p!sspoor. In sport i seem to get better MPG. I just can't understand why it's so poor. I'm going to get it in to vw and get it looked at as I'm not happy with the mpg otherwise I love the motor but the poor economy is killings 50quid admittedly around town is returning 34mpg that's worse then my 2004 a3 tdi 140bhp. It's frustrating.
-
Well I managed to crack 50.3mpg on my journey to Benfield this morning (hoping they actually fix my dodgy electronic handbrake rather than just clearing the fault codes), loosely following my normal commute and then peeling onto the A1 for an extra 5 miles (17 miles total). Ambient temp was +2C. The way the journey went to the point I dropped the missus off (45mpg at that point), I’d have probably managed 47 if I had headed to my work normally, as the last few miles of the A1 leg is downhill and I saw my mpg go from about 45mpg to 51mpg before the last bit of journey on Scotswood Road brought it back down again. It was in Sport for most of it, while in Sport the mpg was creeping up nicely, switch over to Normal and the rate of increase slowed right up, so I switched back to Sport after around a mile. My mpg does seem to be bouncing between 45-47mpg without regens and 40-42mpg with active regens on my commute to give 44mpg ave.
MisterP: How short is your commute? Mine is about 12 miles and I am rarely stuck in traffic. My local dealership claim to take mpg concerns seriously if your long term mpg is less than 40. Do you fall into this category, or just have a few really bad (low mpg) journeys when you go through town?
-
MH my commute is approx 7 miles admittedly there is a small section that it stop start but it's at a traffic light. All moving at an average 40mph. My long term mpg has today read 40 mpg which is p!ss poor. There is no two ways about it. Even if I reset the mpg during my commute I still won't get more than 36. Otherwise I'm loving the motor but it's a shame it's not living up to what vw suggested.
-
I must say I am getting fairly alarmed at some of the mpg claims some people are experiencing, whilst others seem to be ok. Part of the reason I'm changing to a GTD, is to get away from my current 26mpg in the 2.5T mondeo. I have a 30 mile round trip to work, 95% motorway, so i am expecting to get well into the 40's mpg, but from what i'm reading this is by no means assured. It sounds to me that it could be to do with the nature of a brand new model, where the gremlins are quite worked out yet, but the level of inconsistency in reports on this site alone are certainly major cause for concern.
-
Broom you should be fine on the mway tbh. It's the city commute that is causing me concern.
Anyone else experiencing regens galore. In the first 1000 miles I think I had one. Since it's too many.
-
MisterP: I must admit, on a 7 mile commute, I’d be lucky to hit 40mpg for the journey in my car (my car is showing between 38 and 40mpg 7 miles in to my commute) and I’d expect to have an even more active DPF than my car already has, which would hammer the mpg even further. Do you do a few longer journeys in the week to clear the DPF (20+ miles)?
Broomthundle. On a 15mile each way commute on the motorway I would say you stand a decent chance of getting 50mpg every day if you stick to 70mph, or 45mpg if you stick to 80mph, assuming the roads aren’t clogged, and you should be driving with a pretty clear DPF too. It does seem to me that this generation of high output 2.0TDI engine does crucify mpg on the shorter journeys and I was expecting it to be a little better than my last car because this one is supposed to heat up quicker. DPF regens are far more prevalent on this car than my last one.
With the GTD engine it seems that there is a tighter band of conditions you must meet on your journey that will allow you decent mpg than was the case with previous gens and putting your foot down has far more repercussions for hitting your mpg than it did on the older engines. Any journey less than 15 miles seems to be killing mpg on the new engine.
-
Bloody hell MisterP, must be something wrong with yours (or you feet are made of pure lead :laugh:). I nipped out at lunchtime to the shops. Car was stone cold (having arrived at work at 7.15am this morning). Ambient was only 4°C, and the shop was ¾ mile away only. Just dove the car normally there and back (total 1.5 miles), the temperature gauge had only started to move off stone cold and my MPG was already 36.3 !
I really have to stand motionless for a good while (or worse still crawling at 5 mph for an extended time), or ragging the arse off it to see less than 40 mpg, which I have once only, when I had a real play with it and still got 37.8 !
Must really be something wrong with yours. Whilst it comes no where near to the advertised claims, mine at least, still isn't too bad.
-
MH if be happy with a reading of 38-40. I'm not getting more than 34 ATM. P!ss take.
Norbreck no lead foot I'm on good behaviour with my licence :tongue: so I'm a cruiser ATM. I have emailed the dealership today as I am still awaiting my mats that they cocked up when i took delivery. I'm really torn at the moment whether to see out the next month and see how I get on after or alternatively raise a grievance with both the dealership and vw central. I can be stood still for a small while and the mpg would decrease like a stop watch.
-
Ha ha, I believe you....honest.
Deffo sounds like there's something wrong there. Obviously it's normal to see the MPG drop when stood still (although to be fair the start / stop should mitigate a lot of the losses providing you are not in the middle of a regen). When stood still mine obviously drops, but not like a stop watch like you say.
I can crack 50mpg pretty much every night on the way home, even with the cold temperatures. Also, it's important to understand that where I work is 100 yards from a roundabout, and that roundabout leads into another 200 yards further on. The whole of the business park and surrounding area where I work funnels through these 2 roundabouts as they are the only access to the nearby M62 motorway, and it's gridlock every night. What this means is that no matter if I leave work at 4.30 or 6.30 pm, that first quarter mile takes me anywhere from 10 mins to 30 mins to complete, and I can still crack 50mpg on my 15 mile journey home cruising at no more than 70-72 mph (can't really go any faster anyway). If I cruise at 80 (if conditions permit), this will drop to about 45-47 mpg (pretty much the same as MH said).
You may have seen the thread recently with I took 4 large adults down to Cardiff (with a fully laden boot) for a weekend, and still managed a respectable 56mpg for the whole weekend. With just the wife and I and no luggage, I think I might even have cracked 60mpg !
-
Thanks for the input norbreck. It's annoying really that I'm getting petrol mpg around town. On a mway run I'll get the 50+ however it's the driving in and around town that's really shocked me as I said I was averaging just under 40mpg in my a3 tdi
I'll wait for the reply from the dealership and see what I get from them

I'd definitely get it in for investigation ASAP. I'd tell them about all these forum users who are getting "much... :whistle:" better mpg. My dealer did listen to me when I made it clear that numerous forum users were getting their front mounts replaced - despite a VW TSB that said do nothing... Hope you get it sorted soon:smiley:
-
Thanks mate. Appreciate it I have contacted the dealership and await their response.
-
Back to Benfield and waiting for them to open so they can fit the parts ordered yesterday, 51mpg on the 15 mile trip down, again looking like 47 mpg had I been going to work, not too bad. Just hope the twits don't take it out on their lunchbreak again. It apparently only went on diagnosis, yet went 8 miles and had every conceivable option changed and button pressed on the dash and in the MFD. It wasn't available until after lunch, despite me wanting it back for lunch because it was only ever going to be a diagnosis job. Some fecker is treating this as their runaround. Won't be coming back there. They had to find the car again, despite telling me that they'd parked it out front and giving me back the keys. It was locked in the back of the compound and blocked in.
-
MisterP. just to prove I wasn't puling your leg, here's the readout from the journey home last night.

Notice that average speed only 29mph, because I was sat in traffic outside work again for 15 minutes.
-
Norbreck: Given your 15min wait, and the fact DSG is supposed to be 10% thirstier, does your car run on fairy dust or witchcraft? :whistle:
-
Nah....pure skill as a driver :whistle: :whistle:
Serious, don't know MH. I know the computer is about 0.5-1.5mpg optimistic from my checks, but that still equates to about 51.5 ish ? I think maybe part of my "success", is that my 10 miles on the Motorway each night (M62), whilst pretty much always moving steadily with few real hold ups, only travels between 55-65mph most nights due to the sheer volume of traffic, I guess that's the sweet spot for fuel efficiency.
As an aside, I had a stark reminder this morning of how much the colder weather affects it. All this week leaving for work (about 6.30am ish) it's been below freezing, so with the heaters on full (yes I'm a softie and like my comfort), which obviously means the PET heater is switched on as well, heated seats and heated rear window, I've only been getting about 41-42mpg going to work (which is though a major city - don't use the motorway in the morning). However today, exact same journey, but the ambient was now 10°C, I got 48.7 mpg !
-
Norbreck:
Set off at 7am and it’s 9.5C here today and I got 51mpg on the long Benfield run. Yesterday it was 2C at same time and I managed 50mpg. I would say it is the use of the heaters, heated seats and the rear heated window that has killed your mpg rather than the ambient temp itself. Must be quite a load on the battery/alternator. I don’t usually put the heaters on unless it is so cold that despite defrosting the windscreen, it is cold enough to start freezing back up and I have noticed very little difference between mpg in the cold (2-4C) and the not so cold (9-12C).
Can I assume that with today’s ambient temp you used much less heat assistance than yesterday? If so then your increase might be more for much less electrical load than the car having an 8-10C head start in warming up the engine quicker.
10 miles on the motorway at an average of 60mph is probably a huge help for you. For almost half of my journey I am between 70 and 80mph (usually nearer 70mph due to volume), but the rest of the time it is 30-50mph on the minor roads with almost no stoppages, but a few roundabouts to slow me down.
-
Norbreck thanks for making me feel that much better. :wink:
Not as cold in Brum this morning 11c got it up to 37mpg on my commute in. Shockingly driving around Brum yesterday I managed to get it up to 48mpg and that's not driving like miss daisy.
-
I just caned it back to work from Benfield and got 45mpg on the 6 mile trip. ½ a mile of flat 40mph road, then a mile of a wickedly steep sliproad up to the A1 (the road below is about 350 yards below the A1) and doing 80mph for the 4.5 mile along the A1 and a mile of 40mph.
Funnily enough, as I got my car back from the dealers before everyone’s lunch break, my car had been driven less than a mile – presumably they found some other mug’s car to do take out for a lunchtime jolly.
-
What fuel you currently using MH? You switches to Asda a yet or still on Shell?

Currently running Esso. Will try Tesco or Sainsburys next unless my car has tuned over a new leaf.
My car is possessed today. Been to Newcastle centre from work for my evening NEBOSH course. Caned it most of the way there (11 miles as I had to pick up the missus and drop her in town too) and got 49mpg. Drove home at 8:30pm, caned it for 2 miles and got stuck doing 60mph the rest of the way home - 52.3mpg (peaked at 53.6mpg) for the trip. This is kind of what I was hoping my GTD would be like....wonder how long it will last.
-
keep 'caning' it!!! :P - sounds like it just gets better!!
-
I am very close to ordering a GTD and mpg is a consideration.
Am currently driving a 1.6TD Focus (new model), if it is any consolation, I check my MPG brim to brim because of how my company re-reimburse me. I get anything between 46 and 52 mpg measured. I have tried driving it hard, gentle and stupidly slow, the mpg remains similar. I think this is due to my Focus having the 18inch wheels which ruins the mpg on this car compared to the standard 17's.
What I am saying is, if you can get similar mpg out of a GTD, especially with a DSG gearbox and considering the extra performance the GTD has over a 115bhp Diesel Focus. Then it isnt all bad really :)
Just a little perspective really.
-
karlak: Love what my car has been doing over the last few days, but when you're getting 42mpg and driving sensibly compared to caning your last car of similar output and getting 50mpg every day, it's a bit of a letdown. Expect to average 45mpg and you won't go far wrong. Unless my recently recently acquired good mpg is a blip, i'd say driving it a bit harder is good for the mpg. I think it may be a blip, the weather has been unseasonably warm and my commute over the last few days has been longer than normal with driving to my "local" VW dealer for warranty work - may have kept the DPF clear.
-
46mpg on my commute to work, it was being driven quite hard on a few stretches, probably could have gotten 47-48 i'f i'd been careful. Car seems so much livelier, not sure why, maybe it has crossed a programmed running in threshold at 3000km/1870 miles. It has just done about 2030 miles and the last 130 miles seem to have been very good. Maybe it's the sorting out of the handbrake and maybe some associated drag or car performing at less than its best with a logged fault - autohold release is much smoother now in use.
-
I've just crossed 4000 miles now and it seems to get up to 45mpg with ease. Consistently getting low 50s now on my commute to work in Sport mode.
Love it.
-
1800 miles on the clock and mpg is getting better all the time. 120 miles in last two days and 55mpg on the computer and very accurate when checked against fill up.Asda fuel :)
-
Reading this thread with interest...I've put the car in individual, everything sport except acc and driving the car harder...mpg much better, plus 50...and much more fun!
-
Got 48mpg on the way home yesterday and 47 on the way to work today - hope it lasts, I've probably averaged 49mpg indicated over the last 150 or so miles, the preceding 150 miles were diabolical though!
-
Another refill and best mpg to date of 44.52 on my GTD with only 900 miles on it - mind you I have used cruise a few times in that period, so no doubt that may have contributed to the better mpg!
-

Could the milder weather we have been having the last few days be helping?

We say milder weather, but it hasn’t really got milder in the North East, it just hasn’t dipped as far as expected for this time of the year – I’ve had the tiniest bit of frost on one day since owning the car and most days it has been 4C to 10C. I don’t expect my mpg to dip 15% when the ambient temp has dropped from 8C to 3C and I haven’t been making use of any heating devices.
The milder weather would help, if colder spells had you hammering your battery with lots of fan heat, heated seats, heated rear window etc because the alternator will be working overtime and causing your mpg to dip on shorter journeys. I haven’t been using all that at all, so the only advantage is maybe that slightly warmer ambient temp meaning that my car has taken maybe a mile less to warm up. With synthetic oil that is thin even at colder temps, the biggest cause of low mpg in the moderate cold will be the extra load on the battery. If I can go a full tank with decent mpg then I think I might have turned a corner.
-
Got 40mpg on the way into the office today. Things are looking better
-
Well, I broke my record today. Drove home from Glasgow to Edin, approx 60 miles. Got 55.2mpg. That's me sitting on the motorway with adaptive cruise set to 75mph. I seem to be getting my best mpg making this journey. Going from Edin to Glasgow I only seem to get 45-ish
-
There has been some gusty westerly winds this week - could it make that difference heading into a 25mph headwind?
-
First full tank of fuel gave an indicated 50.3mpg, actual mpg was 48.3. Mixed driving reasonably gently to speed limits with mixture of motorways and regular 12 mile commute cross country with 3 mile through town. Aircon left in auto at all times. Slightly annoying but having taken it down to 40 mile range only managed to get 43 litres in to the tank.
Generally impressed and 3 mpg better than my Scirocco 170 over same roads, expect that it will improve by a good 10% once run in
-
My mpg has dipped again on shorter journeys. Below 12 miles journey length, the car seems to settle for 44mpg right now, and 15+ miles gives me 48-49 mpg. I have seen my oil temp vary a lot between 90 and 97C depending on whether i've been driving it moderately hard and it (seemingly) is going into regen, and low load where it has an oil temp of 90C. Seems like my car is running a little cool when it is not being driven hard - i'd expect an average "warm" oil temp of 93-95C - maybe the cooling system is working a bit harder than it should, making the oil take a bit longer to get to temp and keeping the temp a little lower than it should be. The effort taken to overcool and running the car a liitle cooler anyway might be affecting my mpg negatively. Anyone else seen this on theirs? My car is pretty much 4C cooler than the Scirocco was, at every load scenario.
As per Happyhippo's comments, the "empty" or near empty indication on the MK7 is very cautious - the car is probably good for another 50 miles on "empty".
-
what fuel you using now Matthew?

what fuel you using now Matthew?
Still on the last of my Esso, will be filling up today or tomorrow. Will try either Sainsburys or Tescos, although Tescos is a few miles detour from work to the nearest one (Kingston Park), and Sainsburys is right on my commute.
What kind of results are you getting now, and what fuel are you using?
I'm really surprised to see my GTD running on average 4C cooler than my Scirocco for every load scenario. Not sure whether it's intentional design or my thermostat operation is a little off (but within tolerable limits).
-
using esso at the minute and even though my work commute is only 4 miles, longer journeys still give high 40s low 50s in the cold. sainsburys have got that spend 60 quid and get 10p off a litre offer on again. I think maybe the winter diesel is dragging the mpgs down slightly.

If I had a 4 mile commute, i'd be lucky to see 40 mpg in mine, unless it was all on clear 40mph roads, sat in 6th gear. Maybe on my longer commute I have the opportunity to drive mine a little harder (which won't help the mpg) Not sure I could spent £60 in Sainsburys right now unless I built up the Christmas booze cache.
-
Sainsburys fill up last night - 48mpg to work this morning (7C ambient temp) - I think that's as good as I have gotten when only going to work and not beyond. It was a pretty sedate commute - I was doing 60mph for half of it where I would normally do 75 (volume of traffic permitting).
-
Today - 60 miles through towns, hilly countryside and road works. 53.4MPG on the computer, took a photo but no idea how to upload. Over 2100 miles its averaging 49MPG which is good enough for me :smiley:
-
Ahhhhh jealous of you lot (Although my MPG is due to low and short trips moving home, under 1 mile each way about 30 times). Averaging 34.4 so far overall. Manage to push 48 on a trip to the Amex today (about 15 miles, but mainly sat there at 70 on ACC).
I'm sure as i do more trips it will puish up, not too worried though
-
Dipped a little today - 43.4mpg on the way to work, ambient temp was 3C today as opposed to 7C yesterday. With the gear change prompts putting out some odd suggestions, I got the impression that I was undergoing a passive regen.
-
about 350 miles on the clock at moment;
currently averaging 45mpg ish
I drive hard - so cannot complain, and I'm sure it will get better as the miles clock up.
Another thought was - the gearing is completely different to my old MK6 GT - and perhaps it takes some getting used to.
-
Not too shabby on my way home from work last night - 6.5°C ambient. That's only about 5% off the official combined cycle for a DSG.

It is very easy to find yourself in the wrong gear in the GTD when you want to put your foot down and see an instant response - it needs to be pushed harder than any other TDI I have owned to get the best out of it.
Mpg dipped again to 42mpg on my commute this morning, after being a healthy 49mpg last night, although we have gale force winds here right now that weren't here last night.
-
My city commute mpg has regressed was getting a good 40-42 in and around town on a cold morning start. Then the last two days back to mid 30s whether it's cold or engine has been running a while. Time for me to contact VW methinks.
Booked in for Friday 13 :sad: they will keep the car for a few days so that they can monitor the mpg on it and also look at the squeaking from the front suspension. top mounts prob.
-
Had a few days/50 miles of poor mpg, around the 40mpg mark. My car seems to bounce from 47-49 mpg at it's best to 40-42mpg at it's worst (regenning) on my commute, averaging 44-45mpg for the tank. The car is a lot looser, so I might find myself putting my foot down a little more when conditions allow. Still poor that my car is noticeably regenning for around 40 miles every 250 miles or so and the oil temp variance between regenning (car touched 101C yesterday) and not (90C at low load, 92 at high load) seems larger than it was in the Scirocco. Maybe regens would be less frequent if the car's normal running temp was a little higher. Seems a daily commute of 12 miles is not quite enough to keep the regens at bay, but 15 miles each way is (when I was going to Benfield for warranty work).
-
let me know if you get any more regens using the sainsburys diesel. my tiguan hated sainsburys fuel and would kangaroo hop down the road when it was playing up. didn't do it much once I switched to shell.

my 200 miles in on my Sainsburys tank and I'm averaging 45mpg, a mix of the best and worst commute mpg. Can't say whether the regen period experienced was down to the Sainsburys fuel or the previous Esso. Just added some Miller's and the car feels a lot livelier, but not enhancing the mpg noticably. A 35 mile trip on varied roads up to 80mph today yielded 47mpg. Sainsburys doesn't seem any better or worse than Esso for me so far.
-
I'm quite surprised by the real life MPGs in this thread, though has anyone managed to put 10K miles on one yet?
I haven't taken delivery of my GTD yet, but the guy at work with a GTD Mk6 was telling me he could get 60 out of it on a run - I sincerely hope mine does even if it takes some time to loosen up as I shall be a bit miffed if it can't beat my 270k 306 HDi which it stands to replace - I can still get 53 out of that on the work commute.
-
lol 280 miles done and so far 34.8mpg in total :P - newer runs are starting to edge 45 if driven nicely :P - trying out eco mode this week :)
-
C2K: My dad has done 7k miles in his now (GTD DSG) and regularly does Southampton to Newcastle. He gets about 48mpg on that trip, setting the ADC to maintain 80mph on motorway stretches. No way I'll ever see 60mpg on mine, found it hard to do less than 50mpg in my Scirocco, only racked 50mpg once in the GTD (2500 miles on it now).
Mine seems to regen noticeably every 200 miles for about 50 miles, was never aware of regenning in the Scirocco, always happening very subtly. The GTD seems to run a consistent 5C lower in all situations eg low load 90C, high load 94C, Regen temp up to 101C. GTD seems to take almost twice as long for oil to get to temp - I'm sure it's killing my shorter journey mpg.
-
I'm surprised at the frequency of regeneration. Looks like I'll have to map that out longer term and hollow it out haha.

if your talking about a dpf delete I wouldn't bother as it's soon to be an mot failure if it's not on the car.
-
Has anyone tested how many miles you get on a full tank (DSG vs Manual)?
-
Another fill and I'm now up to 46.99 mpg, but I am using adaptive cruise, something I never thought I'd do, but at times you can and it obviously pays in the mpg stakes.
-
Managed to average 63.1mpg on way to work this morning. mostly congested motorway, but just shows what it can do. Manual gearbox, 300 total miles on clock.
-
Think it would help focus these posts a little if people specified transmission, total mileage and then MPG. :)
64 is good stuff. :)
-
It seems that from February 2014 any car that was originally fitted with a DPF will now fail the MOT if it is removed.

I got 58mpg this morning on my 40 mile commute of unclassified and B roads. Thought that is pretty good considering I have DSG, overtook everything that got in my way so anything doing less than 60 and I only passed the 1000 mile mark today.

But of course. Ask yourself though, how a hollowed out, mapped out DPF looks any different. ;)
Most tuning groups do it this way, common on Renaultsport DCi Meganes for instance.
-
Had no real opportunity to put my foot down on the way to work today and managed 48.3mpg (5C ambient temp). Great, but if I drove that way every day, the exhaust wouldn't get hot enough to passively regen, so that figure would soon take a large dive.
-
well driving like miss daisy last night to Chichester and back, i managed an average of 41.0mpg there and 45.1 back. (Going 60-70 on ACC a lot of the time) about 17-20miles each way.
Really not getting great figures despite being in eco or normal..... hmmmmmmmmm
-
I leave it in Individual with everything set to Sport, apart from Eco for AC and ACC. Also I only use the AC for occasional defrost etc. Long term average 52mpg actual. Manual transmission; 2600m clocked up so far - mix of long distance and local commuting. High 50's on some steady longer runs. Computer only seems about 1mpg optimistic based on recent refils. Happy with that considering the performance.
-
I've now just crossed 2500 miles and my long term average is 47.1 mpg. Now when you consider that about 2000 miles of this is just my commuting to work and back (circa 10-12 miles depending on traffic), I'm pretty pleased with that.
Going home from work last night was a particularly good run (without the major hold ups I normally get for the first mile), and I averaged over the 15 miles journey home 57.6 mpg (at an ambient of 6.5°C).
I've tried pretty much all of the driving styles, (Comfort, Normal, ECO, Sport and Individual), and have settled on Comfort for the best overall compromise. Unlike some others, I haven't found driving in ECO, has a negative impact on fuel economy, just no better than Normal or Comfort on my car, and with the added loss that in ECO you loose the nice cornering light function of the headlights for some strange reason ?
It does seem that the more miles the car gets, the better it feels, and I can't wait for the warmer weather in the Spring / Summer when I think 60mpg + should be achievable for the same journeys. To be honest, as it currently stands, if I take the Urban published figure (49.6) then I'm achieving about 95% of that figure or if I take the Combined figure (60.1) I'm getting about 79% of that figure, but that's probably not too comparable as most of my journeys are urban from cold starts each time.
-
From my experience (also recently crossed 2500 miles), Normal is the thirstiest mode (for my style of driving at least), but it seems to have more clout through the upper gears than Sport, which has more lower end clout. Ideally I’d like to stay in Sport 90% of the time and for those times I put my foot down in 4th/5th/6th, I wish the car would chuck it in normal for the brief spell of acceleration.
Unless you have a DSG to take advantage of the freewheeling option, I’d forget Eco mode, does nothing for my economy at all.
I think VW missed a trick with the accuracy of the MFD mpg display. They always used to be 9% optimistic, now they’re 2-4% optimistic. If my 46mpg (indicated) was reading 49mpg for an actual 45mpg, as it would have done in the Scirocco, then I probably wouldn’t have thought I was doing so bad for this time of the year. Just wondering why VW tightened up their MFD mpg accuracy so much when the car would have seemed closer to published figures by leaving it alone – tighter laws brought in maybe?
For those that don’t have ACC/DCC fitted to have a “cComfort” setting – I’m assuming Comfort (apart from the softer damping of the active suspension) has all of the engine settings of “Normal”.
As per Skinnee D, I also set everything within individual to Sport except the aircon which is set to Eco. I don’t routinely use the active cruise control, no real point on my commute – moost benefit to the motorway milers/longer journeys.
-

Probably because they can through more accurate metering of fuel required to meet the emissions regs... Previously, the metering, certainly on diesels, was less accurate so they had to give themselves a margin for error... I suspect that it is a side-effect of that...

I'm in the "everything set to sport except...." Crew. The car delivered late August has just tipped 6000 miles and the average on the mfd since start is 47.1. So, yesterday I had on of those "how did I get here" journeys which means I was taking no notice of gear change suggestions or trying to change gear at 2000 revs, I did though drive it like a petrol as has been previously suggested. So when I went for the average for the journey (with one eye shut as I thought it would be horrible)...53.6 mpg, my best ever! My conclusion is just drive it, don't hang around and all is good.
-
Sounds great! :)
Have to admit, if i just drive it i get nearer 25-30mpg.... if i'm ms Daisy, i get 35-40... and just pushing the 45mpg on some longer trips. However my daily commute is pittance (2-4miles) - so kind amy own fault :P - do have some much longer trips coming up soon though :)

Yep, better get them longer trips in or regen will take over...you might have well kicked the **** out of it rather then have a regen...at least you get to enjoy IMO :smiley:
Btw...really glad you are enjoying.
-
hehe :) - still very much enjoying it :0 - wishing payday came round sooner, so i could get some more fuel in it hehe :P
It might bet the type of fuel to be fair, as only done 1.5 top ups, both with crappy texaco/esso fuel.... will try BP or similar next week.
Also... yes the regens :P - well... it might be me, only heard a regen once.... assuming non-audible once driving, only visible on mpg?
-
I've not had a regen since starting to drive it properly. The regen was always in Yeovil after driving already for 25 miles....sat at the traffic lights, stop start not working and revs sitting at 1k...result yuk mpg. I'm also now on sainsbury's and that seems better. Cheeky little trip to Solihull tomorrow a.m. Then a drop down to Taunton and then home...mpg will be interesting me thinks.

Those commutes will kill mpg through the engine not getting up to temp or anywhere near it (you'll be lucky if your water gets to 90C at that point, your oil temp will still be at the bottom of the scale (<50C). 2 mile into my commute, the car will probably be at around 32mpg, at 4 miles it will maybe be at around 38mpg. Constant cold running should clog up the DPF pretty quickly with forced regens needed to clear it - they will also kill mpg.
The GTD does like to be driven harder for no mpg penalty over what I am usually getting - 46mpg today for 12 mile commute at 6C ambient temp with plenty of hard acceleration when there is a significant change in speed e.g. 30 road to 50/60/70 road.
Sainsburys is as good as anything else i've had in the tank, at least as good as Esso and far better than Shell V-power. My Scirocco used to drive best on standard Shell compared to anything else, but that's not the case with this GTD.
-
Ohhh.....so close.......... on my way ome from work last night - another good run (albeit this time, I was driving very sensibly) :grin:

It was reading 61.7mpg at one point, but I then hit 5 sets of traffic lights in a row :sad:
-
Now that is impressive!!!
I managed 12.2mpg on way way to work this morning! Hell yeah!! :) :evil:
I have noticed, not having the stop start active (on small trips) really does damage any mpg :P
I'm still thinking mine will improve as i do some higher trips, and surely enough on the longer trips it does improve quite significantly. If i was deperate for high MPG i would have gone for a lower sized engine blue motion. The GTD's kick and speed is perfect for me, and i'm more than happy to take a dip in MPG for the smile on my face :) - aware that others may not see it the same way, and whilst getting less than a GTi equivalent MPG, there could be questions as to why i got a diesel :P (Well the answer was simple, 29 days from order to delivery, as it was in stock, and looked so dang sexy!) :)
Loving all the feedback, and especially the type of fuel feedbacks, ie brands v other brands, and premium v standard diesel.
Got to have some fun last night round a few roundabouts in the middle of no-where, whilst the mpg wasn't great, the excitement levels were awesome! :) - It sticks like glue! :)
-
Something will have to be very wrong with your GTD to be outdone in the mpg stakes with a GTI for equivalent driving style, journey length etc. Someone will have far more fun in a GTD trying to maintain 40-45mpg than someone will in a GTI trying to achieve the same mpg.
Being in a manual is handy for deciding when you want the start-stop to work. If you pull up at lights that you know will change in your favour within 20 seconds, or stop briefly at a roundabout then it’s handy just to keep the clutch dipped to keep the engine running. Let the engine switch off via stop-start for the longer waits.
Now that 46mpg indicated actually means 45mpg, thanks to the more accurate MFD, I’m not feeling too bad – especially now I can hoof it and get as good a fuel economy as I would overall by driving like a nun. If you do shorter journeys (less than 15 miles) typically, you might have to drive it a little hard on occasion to get your exhaust temp up for a longer proportion of the journey.
-
TBH noobmonkey, if your journeys are typically that short that you only get 12-15mpg, then I'm surprised the VW dealer was still willing to supply the car (unless you didn't tell them) :evil:. Due to lots of problems with DPF's over the years, it's my understanding that the dealers are supposed to get some information from the customer prior to advising if a diesel is suitable or not. I know on my last two VW diesel's I was asked exactly these questions - total yearly mileage, typical journey length etc.
As I understand it (and stand to be corrected here), if the DPF reaches saturation point and the journeys are not longer enough for a regen to clear it, the light will come on within the dash. If you need to take it too the dealer, this is classed as non warranty work and they will charge you. It the saturation reaches critical level (90-95%), then the DPF can well be beyond saving - and a new one runs at over a grand (plus fitting) !
Maybe the petrol GTI would have been a better bet for you in this instance ?
-
Correct, the dealers should have asked you to see if a Diesel was the best option :lipsrsealed:
And yes, its a costly thing to repair :embarrassed:
-
hehe, its only because i'm office based in the past few and coming few weeks, will be out and about much much more in the new year :) (I cover an area from new forest to dover and up to london, so i should get enough long trips soon enough )
- And was via a work lease, so they pretty much ask nothing ;) - other then do you have a pulse and can you pay...
Anyway... tis all about the smile, screw the regens :P
-
Fair enough then :smiley:
-
Tbh I wasn't asked and I get a regen every two/three weeks.
-
320 miles today....up and down the M4..M5...M42 and A34 with some "I'm bored" moments if you know what I mean :wink: 48.1 I'll take that!
-
I had an experiment today. My normal working commute I can get 52mpg with crushing at 70/75. Today I took it down to 60 and achieved 58.9mpg with a fair bit of stop start traffic.
Seems to me to crack the big numbers it needs to be done at 60mph.
-
silly assumption, but assuming cruise control? or just normal drive in 6th?
-
Tbh I wasn't asked and I get a regen every two/three weeks.
I seem to get one every week/250 miles and I would say that about 1/3 of those are active where the stop/start stops working and the idling is at about 1000rpm. Had one coming in this morning and the car did 43mpg, with the fan blaring and the hot/burnt smell coming from the exhaust when I parked the car up.
Never had a single active regen in the whole time I had my Scirocco. Doing a 75 mile round trip tomorrow - will be interested to see what my GTD does.

MH mate I get one every 250 miles too and it bloody stinks when you park up. :sick: car is with VW today for the economy test. they initially suggested that they will do a brim to brim test to see how 'economical' the car is. I told them that I am not paying for a full tank of texaco fuel (closest petrol station to the dealership) and not get to use the fuel. your test you pay. I am awaiting a call as to what they intend to do as the guy in the servicing dept seemed to suggest that I wold have the car back tonight and one of the other guys suggested that they would keep it for 3-5 days.
-
So they were proposing to fill up at your expense and run the car for a good few days and then determine how much it used by filling again (at your expense) – sounds like a great deal…..for them.
They should be able to act off the MFD indicated mpg and assume it is 3 – 5% optimistic. At that point they should be able to decide whether your mpg is reasonable or not. Presumably they can look at the engine oil temp profile over a period of time (hoping the MFD logs that since last fill at least etc).
I do think the key to reasonable mpg is a clean DPF and getting up to normal running temp as quickly as possible. I don’t think the MK7’s DPF clearing regime is conducive to decent mpg on mine.
My car’s engine oil takes almost twice as long to get to temp as the Scirocco’s did. The oil temp is about 40C behind the water temp on the warm up cycle, whereas on the Scirocco the oil was about 20C behind the water and it easily held 94-95C for the rest of the journey. Mine seems to be maintaining a temp of 90C unless it is in a medium/high load situation where it will creep up (but also seems quick to drop back off to 90C when it isn’t under much load).
For those with better mpg, are you seeing fewer regens? Does your resting warm oil temp generally exceed 90C when not under significant load (not significant meaning maintaining a speed of 50mph or less). What about those with poor mpg/high frequency of regens – seeing the same engine temp profile as me.
If my car’s management system is keeping it atypically cold then I think there might be something in it.
-
Hmmm well 17.4 miles with almost no traffic, sat at 60-65mph with ACC and then a loada stop start for 2 miles in Brighton going up and down hills.... and i get an awesome 43.1mpg! (Awesome in comparison to my usual).
Return trip in 20 minutes, almost rush hour, eeeek!
I understand people say get it warm etc... but if i do, the mpg drops much lower. I still think it is my short trips doing this, rather than the car being at fault, and i will give it a fair test over the next month or so.
My total average since new is now at 36.7mpg (380 miles - so not many miles to be honest)
-

MH - I reckon that my oil temp is 30-40degC behind the water when warming up. Resting warm oil temp is at least 90degC. Active regens have been pretty infrequent so far (can all that heat and fans really be helpful for emissions??? :huh:) - maybe 3 or 4 so far in 2700 miles. Persistent communting days without a decent run eventually seems to trigger one. I'm finding it difficult to gauge when the passive regens are happening, unless I'm on a trip with traffic/lights where I can see the auto stop is being blocked.

They called me at 4.30 to say checked the car there is a noise from the suspension but we don't know what it is requires further investigation so they will keep the car until they can find the problem. I told them what other ppl are experiencing and the guy said he would make sure that these things are checked off.
They said they ran some tests and the car readings are within the requirements so no issue with mpg. He will show me a reading when I go to pick it up.

I made a trip down to Manchester and back today. 225 miles down, ACC set to 75mph and I averaged 46mpg. This is with the boot fully loaded. The trip back up (with an empty boot) got me 50.4mpg... Which is slightly disappointing. I was expecting to be closer to 55mpg. I seem to be able to routinely hit between 52-55mpg on 60 mile trips between Glasgow and Edinburgh.
My first drive in the car was pickup from Warrington then back home to Edinburgh. I hit 51mpg on that journey. I'm now approx 2200 miles in and nothing has changed... Yet.

No change in mpg, but any change in performance? My car seemed to get a noticeable boost at 1900 miles/3000km, this did also coincide with Sootchucker providing power/torque graphs and I started accelerating to 4000rpm.
Having undergone the latest bout of forced regen (averaged 42mpg for the last 40 miles), i've done 2 trips at 48mpg. Going on a longer journey today, hoping to see mpg well into the 50s.
-
My total average since new is now at 36.7mpg (380 miles - so not many miles to be honest)
I have covered 351 miles in my GTi, total average since new is 33.1mpg :whistle:
Meh and worst of all - i misread :| - i'm actually on 33.1 as well :| hmmmmmmmmmm!

Can't understand why anyone would choose this option, it will still sound like a tractor! Buy a gti if you care about exhaust note!
If your only interest is red calipers, you can buy a tin of smooth hammerite for a tenner and a decent can of lacquer which would last years!!

Ahem... Wrong thread?
MH - Can't say ive noticed any changes in performance. You had a fairly similarly specced Roc to compare to where as my previous motor was a sh!t box!

Don't know how it managed to do that as I could see the post I was replying to! Stupid phone!

Ive had good and bad mpg today.
It was sh!te going into Newcastle to drop the missus off for the match and head down to Hartlepool to see a cousin. About 45 miles all in. Some hefty stoppages for traffic for the first 12 miles, then the other 33 miles pretty much maintaining 80mph down the A19 (dual carriageway). First 12 miles was down to 41mpg (more regenning) and recovered slightly to 42mpg at the end of the trip. Almost no wind.
Came directly home from Newcastle to North Shields via the Tyne Tunnel (32 miles), maintained 80mph back up the A19 and the car recorded 53.3mpg for the trip. The wind had really picked up for the return leg, blowing southerly and was quite blustery. So strong headwind all the way back and still did 53.3mpg.
For almost the whole homebound trip the oil temp was 98 - 101C once warm. The whole day's driving has averaged 46.5mpg.
I presume the DPF is spotlessly clean right now.

MH after reading your posts I checked my oil temp on my recent long trip and mine sticks at 90c. I'm using the acceleration of sport mode to get up up to speed quite rapidly and this seems to help my mpg.
-
My findings so far are that no matter what journey I make - I always seems to get much better mpg on the return leg. Even counts for going to work in the morning and heading back home in the evening. I would have put this down to external temps but it has been really mild lately. 13 degrees - that's almost a summers day for us here :laugh:
-
Just took a short trip for a takeaway, and the engine was still warm frmo my best ever mpg trip, but the stop-start was deactivated - surely not regenning after 65 miles of dual carriageway cruising?
-

Yep, used to happen to me before i started using the acceleration.

I've had the car just over a week and managed to clock up over 1100 miles :grin: so would consider that the engine has had time to bed in. MFD showing long term average of 41.7 at the moment, although for a run up to Stockport, saw 46. I've enjoyed the performance a bit, but generally it's been driven pretty well - even though it's a company car.
Couple of mornings this week I've been up to Stamford, around 30 mile round trip, 20 of which are on the A1 at a reasonably constant 70/75. At best I've seen 43.5 and driving like Miss Daisy! Today had a few of things to do around town, about 25 miles total, mostly dual carriageway with a couple of miles of 30mph areas. Drove a little harder to get up to speed and sat at 75. According to MFD, managed to hit a staggering 32 mpg!! :shocked:
My last car was a 320d (184ps one) and I'd drive that pretty hard (75/80 on mway, but use the acceleration to it's fullest) and get around 44/45, could get 55 if drove carefully. Not expecting to see 67 with the Golf, but was expecting 47-53.
Maybe it needs more time to loosen up rather than just the mileage? I'll do around 600 miles next week so will be interesting to see if this improves, but so far, not impressed

I'm finding that bouts of persistent junctions/traffic lights etc on a trip are really pulling the average mpg down - even with the stop/start in use. Basic physics I know, but all that braking and reacceleration is making quite a difference when I'm comparing mpg between otherwise similar trips.

Good question...10k on fixed servicing, but I'm guessing maybe up to somewhere approaching 20k on long life/variable servicing for some long distance drivers?

When long life servicing was first rolled out on my 1st MK5 Golf (2005), mine was set up for it and it did 18k miles to the first service,that was doing 12k a year mixed driving. Assuming the regime parameters haven't changed, the motorway milers should see almost 20k miles between oil changes.

Much the same for our old 2003 A4 TDI - consistently 17-18k for the variable service to flag up, same for all the three services while we had it. Likewise 12k per year mixed use.

MH you're seeing a lot more regens than Mr mate. I probably get one every 3-4 weeks. Mpg drops and stop start errr...stops. My long term MPG from the MFD is 50.3 and that's with 760 miles. I regularly see over that on my commute to work.
Might be worth asking VW to look at how many regens you're having?
Quick unrelated question. With the long term servicing (every 20k) still cover you for three services in the service plan or not?

They won't cover 3 x long life service plans, just 3 x fixed interval ones, otherwise you could get 5 years worth of servicing out of them. Yep the number of regens I have is a little disturbing.

There is no point in asking they will carry out all these tests and give you a print out saying if it's below this mpg wise it's worrying if it's above then it's fine. In respect of the regen they said it all depends on the type of driving you do. That's how they fobbed me off lol. What more can I do other than wait for the first oil change as suggested above and take it from there. Useless some of these technicians.
My car went in on Friday and they said they can hear a sound rattle from my front driver side suspension but they can't trace what it is. But cos I took it on on a Friday it listed their ability to investigate further so they kept the car over the weekend to run some tests. My response was cough cough bo!!ocks... More like your too busy to look today so you will wait till Monday. I said when I collect I want to speak to the dealer principal. Not happy with the way I've been handled. They got the car at 8am and they telling me this at 5pm. They just haven't bothered.

Did you make note of your mileage when you dropped it off? There may have been someone off out in it as their personal runaround over the weekend. When my car went in for one day, it was supposed to be back to me by lunchtime (8am drop off). They told me at 11am it was ready, but I never got my lift back to the dealership until 2pm, even though I was expecting a 12pm pick-up. Someone had it out for their lunchtime and did 28 miles in it.

Never seen this with any previous TDI (6 bought new before this one), a small incremental increase from 0 – 2000 miles in output, but not really in mpg, and certainly no long term gains like that.
My Scirocco 170TDI was extremely tight from 0 – 320 miles/500Km then opened right up and didn’t incrementally improve after that to any great degree, it was as if a switch had been flicked.
If it is the case to expect noticeable improvement with large mileages going on, then it would suggest to me that the increases seen as the miles go on are as a result of engine management programming – intentional retardation of efficiency/output by VW until the 1st service – perhaps to protect the engine with the oil filter probably collecting the most debris the engine will ever give out between services.

Yep I made a note. Won't be impressed if the clock up mileage they did say they have to take it out to see if the can hear the rattle. Not expecting anything more than 3-5 miles really

2,500 miles in 6 weeks in my manual 5 door GTD and averaging 48.8mpg, not too bad as mainly short journeys of 14 miles of up and down roads from cold starts, that's all been with Asda fuel and includes 200 miles of use as a demonstrator where it averaged 29mpg :grin: Only had one regen with the fan running when I parked the car and yes the smell and noise would be worrying if I hadn't known what was going on.

First full tank of fuel gave an indicated 50.3mpg, actual mpg was 48.3. Mixed driving reasonably gently to speed limits with mixture of motorways and regular 12 mile commute cross country with 3 mile through town. Aircon left in auto at all times. Slightly annoying but having taken it down to 40 mile range only managed to get 43 litres in to the tank.
Generally impressed and 3 mpg better than my Scirocco 170 over same roads, expect that it will improve by a good 10% once run in
Second full tank of fuel gave an indicated 51.8mpg and an actual 50.2 driving very similarly to the first tank of fuel. This means its already 10% more efficient than my Scirocco over the same roads and conditions. Only noticed 1 active regen so far so hoping that I might see 55mpg by the spring, using BP standard diesel. Car is fitted with winter tyres which are normally less fuel efficient but I have noticed that the Bridgestones have the worst possible rating for fuel economy as well as wet grip so maybe that will offset some of the improvements.
-
Happyhippo - are you driving it any differently to the Scirocco e.g. gentler because you're running in?
On my 12 mile commute I generally get 41mpg during a regen, 46mpg if not. If I take a trip 15+ miles then i've got a good chance of coming close to 50mpg, and on my longest single trip so far, I did 53mpg maintaining 80mph doing 33 miles up the A19 (dual carriageway).
Regens are a nightmare with this GTD - was not aware of a single active regen during my ownership of the Scirocco 140 or 170, passives were obviously occurring very much in the background.
I would guess that the speed at which the oil gets up to temp heavily influences soot build-up (because the car is not burning fuel optimally) and hence more regens for the shorter journeys.
My Sciroccos were fine with a 12 mile trip twice a day for my commute, and the oil was generally up to temp (94C) 6 miles into my journey. The car therefore had 6 miles each way to aim towards a passive regen.
The GTD takes around 8 miles to get to 90C and if it decides it wants to passively regen, getting up to 94C takes another mile – leaving 3 miles each way to aim towards a passive regen.
I had almost a week of 15 miles each way commuting and saw the best commuting mpg I’d ever seen. For me at least, it does seem that my 12 mile commute is no longer enough for DPF-happy driving.
Without the active regens giving me sh!tty mpg for 40 miles every 250 miles done, I’m sure I’d be pushing a 47/48mpg average instead of 44.

My commute doesn't have a lot of opportunities to put my foot down so I doubt there is much difference in driving styles or speed with the Scirocco. There are a few sets of lights on my route so the stop/start probably helps a bit and at the moment there are a few sets of roadworks that slow me down but also mean more stopping. I also avoid supermarket fuel at all costs as I've always found it less economical previously, I also suspect that the Bridgestones with their poor rolling resistance lose 1-2 mpg.

OK, here goes. :grin:
As part of the ever more stringent Euro emission laws that have been tightened up over the last number of years, the amount of soot debris that a diesel car is allowed to emit from it's exhaust has been drastically reduced. As you may recall, Diesel motors from a number of years ago were smoky smelly things, that used to bellow big plumes of black smoke under load or when accelerating - this is no longer allowed.
To achieve this, manufacturers have improved the efficiency of diesel engines markedly over the last few years, with better fuel regulation, much higher pressure fuel rail systems and using Diesel Particulate Filters (DPF) amongst many improvements.
The DPF's job is to catch the sooty deposits present in the exhaust gasses which are a by-product of the combustion process. It achieves this by having a canister mounted right on the exhaust manifold (as near to the engine as possible). The amount of soot collected in grams is carefully monitored by engines ECU, as it can only hold a relatively small volume.
During normal driving of the car over longer distances, the DPF can self regulate itself by gradually increasing it's temperature and burning off the soot, thus keeping the canister empty (or nearly empty). However, to achieve this temperature the car must be thoroughly warmed and the exhaust / DPF system up to temperature. On a long journey it's not a problem, but on smaller stop start or inner city journeys, the system never quite reaches that threshold temperature for the DPF to operate efficiently, or even if it does, the journeys might be too short to burn the soot off.
In these events, the ECU can instigate an active or passive regeneration or regen. With a passive regen, the DPF will during the normal course of driving slowly burn the soot off - you the driver rarely notice much when a passive regen happens.
With an active regen, the ECU significantly raises the exhaust temperature to over 900°C to get the DPF to temperature ASAP. During this cycle, auto stop / start will be cancelled and the engine revs will rise to approx 1000rpm, in an attempt to keep the DPF at this high temperature. Once regen has completed, the stop / start is re-activated and the revs fall back to about 800rpm. If the regen ends near the very end of a journey or if it's still in progress when the car is switched off, due to the very high under bonnet temperatures, the cooling fan will run on after the ignition has been switched off to cool the engine bay down.
If you consistently do journeys that are too small to allow even an active regen to complete, then you run the risk of the DPF filling to dangerous levels. Once saturation levels exceed an upper tolerance level (think it's about 80-85% full), the ECU will turn on the DPF warning light on the dash, and the car will need to be taken to a dealership to have the active regen completed in their workshops (this is not warranty and is chargeable). If you ignore the dash warning and continue to fill the DPF beyond 95% full, you risk permanently damaging the DPF and not even the dealers systems can recover it. In that rare event, the DPF would need to be replaced at well over a thousand pounds !
I've surmised some parts, but the above is basically how and what the DPF is for.
-
Cheers for that Nobreck, superb explanation, I now fully understand it now.
So basically if you permanently do 3 mile journeys back and from work mon-fri, you need to fly it up the motorway once in a while for a 15-20 mile journey? Only reason I ask is that my mrs drives it to and from work during the week and is a shirt distance.
A couple of years ago I had an Ibiza cupra diesel and if I put my foot down it used to kick a hell of a lot of spot out the exhaust, I'm presuming this was because it had no DPF as you explained?
-
Kind of defeats the point of buying a Diesel a bit, doesn't it?
-
Yes, modern diesels are not really suited to a life of short journeys only, and do need a good run now and then to clear the DPF out.
Dealers are supposed to ask what sort of journeys and mileage you will be doing before selling you one, but a lot don't. TBH, if short journeys are all you ever do, these days, you are probably better off with a petrol - economy wise there won't t that much in it, and the petrol doesn't have the DPF to worry about.
-
Well I was also referring to having to take the car out to clear the system.
If you were in the middle of regen would you carry on until it finished?
Most people see the Combined MPG figure and think '56 mpg vs 44 mpg,that's the best for me'
-
Do you know when your in the middle of a regen, can you tell? Am I right in presuming you don't loose performance during this process?
Well in my case I wouldn't say it was an issue as at the weekends I am always doing high mileage so it will get a good run...
-
Bring in a GTI with ACT and 55mpg published combined figure and the GTD will be history for all but the 30k miles per year reps. My workmate who lives 1/2 a mile from me (we don't carshare as he gets to work for 9am and I start at 7:30 for a 3:30pm finish) has an almost identical commute to me. He just got himself an Audi A1 S-line 1.4 ACT (140PS) and with just 700 miles on the clock he is clearing 50mpg on almost every journey he does over 10 miles, including the commute to work. The interior on it is beautiful also.

Very interesting topic indeed. My question in though, once your DPF 'Canister' reaches the 80-85% full limit and the dash light comes on, must we head to the dealer? If they're only going to do an active regen, can we not just have a good 30 minute blast on some backroads and initiate the passive regen ourselves? Would this clear it?
The GTD takes around 8 miles to get to 90C and if it decides it wants to passively regen, getting up to 94C takes another mile – leaving 3 miles each way to aim towards a passive regen.
Is it just oil temperature that indicates when the engine is able to perform a regen? Can we say that if we're seeing oil temps of 94 then a passive regen is likely to occur if required?
Fascinating stuff. :rolleyes:
-
Just give it a thorough Italian tune up now and again and you won't have to worry.
-
Once saturation levels exceed an upper tolerance level (think it's about 80-85% full), the ECU will turn on the DPF warning light on the dash, and the car will need to be taken to a dealership to have the active regen completed in their workshops (this is not warranty and is chargeable).
Very interesting topic indeed. My question in though, once your DPF 'Canister' reaches the 80-85% full limit and the dash light comes on, must we head to the dealer? If they're only going to do an active regen, can we not just have a good 30 minute blast on some backroads and initiate the passive regen ourselves? Would this clear it?

At that % of blocking, with the right software (Such as VCDS) you or a garage could start a manual regen.
If the filter is nearly blocked a forced regen could melt the filter from all back pressure and heat so it's probably a filter out and clean job at a competent specialist.

47.8 according to the bord computer on my first full tank... Mixed driving, plenty of motorway, A- road and town driving...
Impressed, so far...

Hmmm... my long term is now up to 43...... Managed 49 the other day on a run over to Lowestoft and back (200ish miles) almost driving like Ms Daisy, but getting past stuff on the A143 of needed. Considering they way I was driving (75 tops on A14/A1 & 65 on A143), would have expected 50's.
1800 miles in, most of that at motorway speeds (70/80) it seems to take an age to get mpg anywhere near respectable 45mpg. Not great really
-
The trip computer was reading 50.8 when I got off the motorway yesterday... I could have stayed on the motorway and tried to maintain that but I fancied a drive through the Cotswolds :grin:
-
Went back down to Manchester today. Trip down yieylded 46mpg. Trip back up 50.5mpg. On the way back I noticed that the MPG stayed a solid 48/49 on the motorway. The last 40 miles is a windy varied speed road with a mix of city driving. If anything I would have the thought the MPG would go down when driving through these parts rather than up. Didn't hit 50+ till after I got off the motorway (was cruising at 75mph)
-
has anyone noticed that if you reset your mpgs a few miles into your journey the indicated remains high 50s. from cold the mpgs are really bad but once slightly warm if you reset it stays quite stable.
-
That's sort of cheating :grin:.
You're resetting the reading when the engine has warmed up and if you do it while traveling at a steady speed then the fuel consumption will be small.
You can see this when you switch to instant mpg read out.
-
I know it's sort of cheating but a lot of people are saying the gtd isn't as economic as it should. if you break your journey into 2 bits ie cold start and then reset once warm then average the two figures I bet it's higher than just leaving the mpgs to go by themselves. it's just interesting to see what you can get when the car is properly warm and looks good for the warm summer months (if we have any) :grin:
-
But it is not representative of your fuel consumption which is high(er) in the warm-up phase...
So you're kidding yourself...
-
All cars suffer from poor economy until up to temp, the trouble with the MK7 is that it takes longer than ever to get to optimum running temp.12 mile journey used to be enough to have a decent proportion of the journey with the heating hot enough to see decent mpg and keep soot at bay with passive regens. Now I find it's more like 15/16 miles needed. I get active regens for about 20% of my driving. Sorry, but that isn't progress. The way the car is set up makes it increasingly less suitable for more users than ever before. I should not be having issues like that with average mileage (10/11k miles).
The effects of cold start will be lessened in the summer weather, as the ambient temp is 15 - 20C higher than it is now, and more humid air makes for a greater expansion under combustion as well as less dependence of lights and heating. Same could be said for any car. My dad is getting his first oil change next week, some say the car will run more efficiently after its first oil change. I guess we'll see soon enough.

Duplicate post deleted. :rolleyes:

no I'm not kidding myself I just said it was interesting to see and yes I know fuel consumption is higher in the warm up phase.

On my 12 mile commute, my first 4 miles are at a 35mpg average , which increases to maybe 42mpg at 8 miles, and by the end, 46mpg right now if there's no regen going on. When I was extending my commute to 16 miles, I was cracking 50mpg. This is when my car isn't actively regenning
For my commute journey then, my first 4 miles uses 0.11 gallons or 0.51L, the next 4 uses 0.079 gallons or 0.36L, the last 4 uses 0.071 gallons or 0.32L. On those terms, the commute extension's further 4 miles uses 0.059 gallons or 0.27L.
If we consider the car at it's top efficiency in the 13-16 mile stint (there will be room for a little improvement, but not much) then at that point then for those 4 miles the car is doing 67.8mpg.
Those first 4miles (33% of the journey) use 58% of the fuel on a whole 8 mile journey, or 42% of the fuel used on my whole 12 mile commute. Those first 4 miles have the water temp up to 90C and the oil temp possibly just touching 50C.
The first 8 miles (67% of the journey) use 73% of the fuel on my whole 12 mile commute. At 8 miles, my oil temp is at or near 90C. At 12 miles my oil temp is at whatever temp it wants for passive regenning - anywhere from 90C to 98C.
Seems to me then that if you're doing 15+ miles on your average journey then you're laughing, and any less than that will see you shaking your head in disbelief at the pumps to a varying extent. That's before the active regens kick in that I see for 40-50 miles every 250 miles which turn a 46mpg commute into a 41mpg commute.
Does anyone else's car warm up any quicker than mine, or do you see similar temps at similar phases into your journey?
-
I'm seeing similar time/distance for the engine oil to warm up. If I've been working from home, I'll take my lad to school, 30 mile round trip. About 1 mile of 30mph, then straight onto dual carriageway for 12 miles, 2 miles of 40 to 30 mph. After the first 15 miles MFD typically showing 42 at the moment. On the way back I've been reaching 44.
Also seen similar economy profile out in longer journeys, only starting to creep up to 47/48 after 50/60 miles. I've only had the car since the 5th dec, but done just over 2000 miles. It did appear to have improved a bit, but I just can't crack 50 mpg yet. Most of my journeys have been motorway or dual carriageway at 70/75/80 and consisting the distances I would have thought 50 mpg should be easily achievable.
Just to add, short journeys around town/ring road really do kill my mpg, down to 34 today with a mixture of stop start, 30mph & 70mph stretches about 20 miles total
-
Ahhhhhh my figures are starting to creep up!
Finally filled up with BP Ultimate, (There's literally no petrol stations near me that seel the premium diesel! bahhh - apart from this one)...
So gave it a go, and then did a quick 22 mile return trip to Brighton. My average for the trip was 48.9 mpg! (Considering my long term is 33.9 now... that's pretty darn impressive!) - and i wasn't driving like a saint either...
SO.... either a premium fuel works a hell of a lot better or.... the car at 600 miles gone has decided it is awake now :)

There's premium fuel and there's premium fuel. BP ultimate is a full fat diesel with better than average additives. Shell V-power is a blend of proper diesel and GTL synthesised diesel as well as the additives. Shell V-power is about 12% less calorific than standard Shell diesel due to the GTL content which has significantly shorter average carbon chain length than the regular diesel component.
You're a lot more likely to get better mpg out of BP ultimate than V-power.
-
Wow... i have no idea what you just said... but it sounds amazing! :) :) :grin:
So, Bp = ok... well at least better than the normal stuff.
-

Think of it like this:-
Normal Diesel is Stella Artois, got some kick but might give you a severe hangover.
BP Ultimate is San Miguel, got same kick, but you won't get so much of a hangover.
Shell V-power is Fosters, it may not even get you drunk!
-
Now i understood that! :P - and i blimmin hate stella!
Wouldn't want to fuel anything with that piddle :) hehe
-
My GTD is a proper wife beater. Can't get enough of ASDAs finest (read cheapest) fuel and still hammers out 50mpg.
Reckon I've got a Belgian built one ;)
-
As the ambient temp has taken a bit of a kicking these last few weeks, so has my fuel economy. Down to 43.5mpg indicated for this tankful. Going to be driving past the cheapest BP garage I know (Byker) later today so will fill up there (it's not usually on my way, except when I go the back way to town for the match). Will see how the BP does.
My dad had his first service a week ago and saw no change in his mpg or output in the next 600 miles.
There have been people on another forum who have suggested that when they've had their GT TDI 150s serviced (because on average they've had theirs a fair bit longer than we've had our GTI/GTDs) that their mpg has improved noticeably. I did wonder whether VW had programmed in a reduction in detune after the first oil service (which you'd assume would remove more material (associated with running in) than any other oil change you'll have. Seems from my dad's findings that this isn't the case.
-
Have you spoken to a dealer about your regens mate? I wouldn't class you as doing short journeys but you seem to have a lot of regens. Also how did your trial with supermarket fuel go?
-
Sainsburys vs Esso there was almost nowt in it. Haven't done Asda yet because my most frequented Asda (Gosforth) doesn't have a fuel station so i'd be going out of my way to fill up at the Benton one.
I'll see if the regens get worse over the winter before I go back. I'm assuming they will do because over the last week, my car is taking an extra 2 miles to get to temp (90C).
-
How many miles are you taking to get to 90 degrees?
Temps around here have been between 5 and 6 degrees the last few days. Takes my GTD 4.5 miles to get oil temp to about 60 degrees. By about 7.5 miles I seem to hit 90 degrees. My journey to work is sbout 11 miles each way.

Seems I have a similar commute length to you - 12 miles. About 8 miles in is getting me to 90C, unless I drive like a nun. First 1.5 miles is on 30/40 roads, no congestion, next 6 miles is on dual carriageway - straight up to 80mph if traffic volume allows, if not then 60mph when the road is a bit busier (difference between holding 60 and 80 can add up to 2 miles onto the distance taken to reach 90C). Last 4.5 miles is on mixed roads, 30 - 60mph, no congestion, but a few roundabouts etc - this is where the temp varies between 90 and 95C for some passive regen if i'm lucky. Had around 4C average when I go to work (7am) over the last week up to Christmas eve. This morning has seen quite a thick frost, will be heading off for the match soon (Newcastle vs Stoke), and everything is defrosted.
About 5 miles for the oil temp to be registering in the MFD (>50C).
My GTD takes a good deal longer to get to temp than my Scirocco. Water gets to temp a mile quicker on the GTD, but oil takes about 2 miles longer to get to 90C. The GTD's oil is about 40C behind the water on the warm up, on the Scirocco the oil was about 20C behind the water on warm-up. The GTD also seems to cool down a lot quicker between trips 30 mins to 2 hours apart.
-
BP fill-up looks promising. A very leisurely 15 mile journey across a hilly route home yielded 52mpg at 2C ambient temp, and the engine was stone cold at start journey.
-
Well, just did a return trip of 185miles, and it was 49.2mpg on the way up and 50.4mpg on the way back :) - much much better, still not amazing, considering it was easy driving, on a mix of eco and normal to test it out. I did notice, one blip in sport, and that shot down about 5mpg almost instantly! :P - but it was fun!! :)
Bp working much much better, but i assume the longer miles aint doing it any harm! :)
-
Did 210 miles from my parents back to the North East yesterday. On the way down to see them I used ACC and stuck it at 65mph all the way and got 53mpg.
Coming home yesterday I was caning it between 80-100mph and got 47.7mpg. Pretty happy with that to be fair, I know it's a way off the advertised mpg but compared to my last car (1.4 Ibiza) its a lot better. Cars jut done 5500 miles too.
Seeing similar warm up times to you guys, although yesterday I'd say took about 8 miles to get to 90 due to the cold ambient temp.

Pretty much what I am getting having run the car for 4500 miles. Haven't noticed any increase or running in gains worth mentioning.
If I keep it below 70 I can get just above 50 mpg on a run with adaptive on.
If I push it to 75 I get about 48mpg...
I have my car in the garage today to have a look at it after I complained to VW about it during their follow up call. They have already phoned me to say there are no faults logged with it (not that I expected any).
Some interesting reading here if you compare the Mk7 to the mk6 GTD.
http://www.golfgtiforum.co.uk/index.php?topic=176242.200
Seems despite boasting a large increase in economy between the MK7 and MK6 the reverse is true - it is completely less efficient.
Overall I am disappointed given that I waited for the MK7 for 6 months based on the stated fuel consumption figures.
Given that I came from an Audi S3 which was about 30mpg - the new generation doing high 30s on a run, considering that petrol is cheaper than diesel and the new S3 is a 300 bhp motor then I don't see how VW have missed the point with the GTD....
-
Interesting thread, after 2.5k and only running premium diesel (mostly BP) since new my GTD is returning 42MPG on average, luckily this is a company vehicle and I pay per mile as I'd be sadly disappointed if this was my private motor. This is 42MPG with sensible driving too, no hammering it around.
-
I've said this before and I will say it again, don't expect anything near the manufacturers figures until your engine has cover between 10-20k miles. :wink:
-

You can keep saying it, but with my previous 6 TDIs I have never seen appreciable gains with 10 or 20k miles on them. I have also never found it difficult to exceed published combined mpg figures on a 50 mile run doing 90mph on the motorway, from 500 miles into ownership, yet now I find it extremely difficult to get towards urban cycle figures.
The biggest reason for economy improvements is bedding in of components, which is done in the main in less than 2k miles. Ever tighter manufacturing tolerances make engine bedding in far less relevant than ever towards seen improvements.
The average driver with average annual mileage will find it very difficult to get near combined mpg on a regular basis with the MK7.
Actual mpg attained vs last gen 170TDI are about 10% worse. What that says to me is that tech has not moved forward appreciably. 10% more power and 10% worse fuel economy. The new tests are not comparable to the old tests. The goalposts have been moved. Test a MK6 under the same criteria as the MK7 and I have no doubt you'd see official combined mpg 25% higher than published figures. No improvement in real economy IMO and eco tech additions to mask some of that.
My dad now has10k miles on his and he had an average 47mpg indicated over that period. Mpg has not incrementally improved and there has been no noticeable step up in economy since his service.
We will all see mpg improvements when the warmer weather is back and some will attribute this to long term running in rather than the warmer weather. Higher ambient temp leading to shorter warm up times and higher humidity that comes with warmer weather will all help boost your mpg by 10 - 15% over what you are seeing right now for the average miler.
Interestingly, on the MK6 GTD threads, someone does state that since their Bridgestones wore out and the replaced them, their fuel economy improved by 10%. That does seem incredible - 10% economy gains from a change in tyres - can rolling resistance differences between tyres make such a significant difference? I was expecting 3% gains at best from better tyres. Perhaps if VW spent an extra £20 per car they might've had most of us here scraping at least 50mpg on most journeys if there are 10% gains to be had.
-
Gulp... I guess my Polo Bluemotion is a different engine, it took at least 20k miles in that before I saw good mpg figures. Was easily getting 65-75mpg without much effort.
I am really surprised at my GTi mpg considering its not even reach 2000 miles yet, wasnt expectng to see 40mpg + at such a early stage of the engines life. Thats not that much worse than your dads GTD figures :sad:
Maybe these new GTD engines are like me Polo where it needs a good 20k miles before mpg improves?
I do a relative long but smooth trip into the office, its 44 miles with 65-75% M1 motorway and the rest normal urban roads. :cool:
-
Do you think car manufacturers are perhaps optimising their vehicles to cruise through EC testing and emission testing rather for better marketing than building cars which are genuinely most economical for the 95% of us who drive the way we do.
Perhaps rather cynical but would appear that way to me..

44 miles (is that each way?) commute with 65-75% on the motorway isn't typical for most. If I drove 44 miles every day with most on the motorway, I wouldn't expect to ever get an active regen (which pushes my tank average down by 2mpg), and i'd expect to get 53mpg from the GTD (and 40mpg from the GTI doesn't seem beyond the realms of possibility in those circumstances), as I have seen 51mpg on a slightly longer commute (16 miles as opposed to 12 miles). Same circumstances would have yielded 56mpg min in my 170TDI Scirocco.
Different people on different routes/different commuting lengths/different driving styles are going to get different results, although patterns do emerge - people on longer commutes see bigger mpg results, with optimum for GTD being >15 mile trips. Side by side though, for my driving circumstances (which haven't changed for my last 4 cars), the GTD is 10% worse than my Scirocco, takes up a far bigger proportion of my commute to warm up and suffers far more regens as a result - both of which affect mpg negatively.
The fact that pretty much all the MK7 Golf engines from the 1.2 and upwards) have "seen" 20% alleged increase in combined mpg seems to lend credence that the biggest change for the MK7 is moving of the testing goalposts for mpg. Far more of the current testing method has the car sitting idle than the old method, meaning that the inclusion of stop-start tech reduces fuel consumption significantly on the new test, hence the "improvement".
-

That is exactly what they are doing, all of the manufacturers are doing it - is it coincidence that all the manufacturers just got 20% better in fuel economy or have the goalposts changed?
Last gen VWs had a combined mpg result easily achievable on all but the shortest journeys and you didn't have to drive like a nun to get there.
Is it any wonder that only in the last year the car companies have arse covering messages in their adverts - "67mpg combined....figures quoted are for comparison between car brands only and may not reflect real driving experiences". They never had to do that before to save getting sued wholesale.
All this does for the consumer is give them false mpg hopes and cheaper car tax - surprised the DVLA haven't jumped all over the car companies false claims for lost revenue. I'm sure all car emissions bands will be re-categorised before long so that only the bottom 10% of all cars get free car tax, and the next 10% get £20/30 tax discs.
-
I agree with the comments regarding the way mpg figures are calculated but I dont think the EU standard has changed for a while. Which means you should see the improvments between the previous generation and the new. :angry:
Manufacturers use technology like stop-start, DSG coasting and Brake regen to boost their mpg figures but exploiting the EU test weaknesses.
All the EU test cycle is done on a rolling road too :huh:
The EU mpg testing is changing in 2015 I believe to give a more real-world reperesentation for consumers, you have to remember all the manufacturers are using the same EU testing cycle, so comparing car mpg A vs B is still true.
I do 44 miles one way to the office, it takes 1hr 5minutes on a good day and so far I have only done a weeks worth of travel in my GTi, Monday so 37.5mpg, every other day was 40mpg +
I am expecting between 5-10mpg increase once the engine has opened up, this is based on how my Polo opened up at 20k miles... I saw a minimum of 10mpg extra since new on the Polo. :smiley:
Even if my GTi only ever peaks at just over 40mpg thats good going, I'm not doing anything silly like 60-65mph etc.
Based on my commute to work and drive style, compring it to the GTi, a GTD should return 60mpg if I had bought one. :cool:

[/quote]
Absolutely... when Kwik Fit threw some own brand junk on my company car the economy dropped from an average 48-50mpg to sub 40mpg overnight. I stuck with it for a week before phoning the lease company and insisting they put GoodYear Efficientgrips back on. Funnily enough the economy returned to 48-50mpg straight away... Driving 30,000 miles a year it would have cost a fortune!
-
Yes tyres can make a massive difference, even incorrectly inflated ones... I used see mpg improve upto 3mpg when my tyres were correctly inflated.
So perhaps this is why many are seeing poor mpg figures, every single car does not go through a EU mpg test, the EU mpg certification would have been done early on in the cars release and once approved tyre suppliers could have changed etc. :smiley:

http://en.wikipedia.org/wiki/New_European_Driving_Cycle (http://en.wikipedia.org/wiki/New_European_Driving_Cycle)
On the current testing cycle, 31% of the urban testing cycle is at a standstill, 10% of extra-urban is at a standstill, combined calculation puts 24% of the car's journey time at a standstill. Pre-fitment of stop-start tech, that meant 24% of the testing cycle performed with the car at idle compared to 24% with the engine off on stop-start tech fitted.
Cycle beating optimisations that do not help consumers real world driving can also take advantage:-
The fixed speeds, gear shift points and accelerations of the NEDC offer possibilities for manufacturers to engage in what was called 'cycle beating' to optimise engine emission performance to the corresponding operating points of the test cycle, while emissions from typical driving conditions would be much higher than expected, undermining the standards and public health. In one particular instance, research from two German technology institutes found that for diesel cars no 'real' NOx reductions have been achieved after 13 years of stricter standards.
I think most of the "20%" efficiency gains can be seen from the above info.
I would be amazed if a run in MK7 GTI/GTD is 20% more efficient at 20k miles than 0 miles due to running in - you would also expect incremental power gains to similar values (a 264PS stock GTI after running in?).
20% is a massive incremental mpg gain (unless you compare worst winter figs with best summer figs). I would be amazed to see that for any engine, Far more likely to see a modest gain within first 500 miles as things loosen from manufacture/assembly, tyres scrub in etc. Swapping out old tyres with crap rolling resistance for better ones at 15-20k miles when the fronts wear out can give 5% efficiency overnight, nowt to do with the mechanicals.

My tyre pressures are checked weekly and are at the approved pressures as per the fuel flap sticker.

you have to remember all the manufacturers are using the same EU testing cycle, so comparing car mpg A vs B is still true.
Not so - I made a decision in March of this year to not buy a Mk6 but hold of for the Mk7 based on the comparative 10% improvement in fuel economy..
In fact it has proven to be 10% worse so the EC figures are absolutely meaningless...
I wouldn't even support VWs caveat that they are for comparison only as there is no direct relationship between the MPG figures between the MK6 and Mk7 and the actual real world results most people are getting..

A point well made. Even more misleading when you compare data for two current VW production models - say Scirocco TDI 177 and Golf GTD 184 - which implies a comparative improvement of around 12 mpg for the Golf on the combined cycle...
-
I'm going to see how far my complaint can get with VW..
Probably not very far as I imagine they will resist any admission of fault as the wider implications could be huge across all model ranges...

Reality is that apart from the inclusion of stop-start tech, the MK7 GTD has little or no mpg advantage over the 170TDI CR unit. That stop-start tech and the fact that 24% of the EU testing cycle is at a standstill is the reason for the 20% quoted gains. Stop-start makes a huge difference to the EU testing cycle but very little to most real driving situations outside a snarled-up city commute. Stick stop-start on a MK6 GTD and there'd be nowt between the MK6 and the MK7.
10% fuel gains seen between 10k and 20k miles that some quote are more likely to be seen as a result of replacing worn OEM tyres with poor rolling resistance for some decent ones than running in gains. At the tolerances modern drive-trains are manufactured to. Biggest gains I have ever seen attributed to running in/loosening up have been from 500 - 1000 miles.

Well, i'm not entirely sure what has happenned, but since my trip to Bucks last week, i'm regularly getting 40-48mpg, even on small trips.
I'm up to lincolnshire tomorrow morning, so might see a few of you northerners :) - and then coming back sat/sun via the peak district and bucks again. - really interested to see how it handles a nice 600+ mile round trip :)
It just seems to warm up quicker and sit happier. It takes 2.2 miles for the water to hit 90, and a further 1-2 miles for the oil temp to get up to 94+.
Not expecting to see 55+, but hoping to get a nice 52/53mpg on the way up / back :)
Car definitley feels a bit looser now as well. In a good way.

What mileage are you at? 90c oil temp at 4 miles seems odd. My car takes twice as long to get there, and I'm sure my mpg would shoot up if that was happening for my car on the warm up cycle.
-
I think he's pre-heating his oil in a chip pan.
-
haha, only at 700 miles, but was 10c today/yesterday... warmer then the last month :P
just took it out, and yup, 4.4 miles into the trip... small roads and then a 60 mph 1mile'ish bit. (Was at 89... but i'll let the 1 degree go :) )

In terms of financials yes but I always buy new cars since there has been no perceived disadvantage of going for the next generation..
Did the EC testing change between the Mk6 and Mk7 GTDs?
Surely all things equal, the addition of a stop start on the GTD would have made the MK6 even better...
-

If the MK6 GTD had stop-start then it would be throwing up 60+ mpg official figures on the combined cycle - still wouldn't have been any better in the real world for most users.
Still puzzled by noobmonkey's warm-up times. 10C ambient temp shouldn't cause the time/distance taken to get to full operational temp to halve. Even at 8.5C ambient temp i've seen no appreciable difference in warm-up time. There have probably only been 5 mornings since I bought the car that ambient temp has dipped below 5C.
In the height of summer (20C+) I would expect my car to take 6 miles to get to full operational temp if it takes 8 miles from 5C. 85C temp (to 90C) rise takes 8 miles, 70C temp rise should take about 6.5 miles.
I do wonder how much passive water cooling is going on in my car on the warm-up cycle e.g. due to cold air passing over the radiator even without the coolant at full flow at lower temperatures. Whilst on the warm-up, I can see my oil temp dip a good 2 or 3C when I engage in a little hard acceleration - surely the opposite should be true. It seems as though the extra rush of cold air passing over it causes the radiator to cool the engine, at a time when the coolant shouldn't be circulating much, if at all. Are our cooling systems overactive during the warm-up cycle (except noobmonkey's), causing poor mpg on shorter (<15 miles) trips?
-
Can confirm that I took my car out today and it was only at 90 after about 7 miles. Ambient temp was at 6.5. Interestingly as I was crawling along at 30/40 the MPG was indicating 47 which is lot higher than other times I've driven it at slow speeds.
-
Got me intrigued too so I checked mine going into work yesterday morning (6 miles). Had a straight run with no queues and at 6 miles the oil temp was just starting to register 50deg. Air temp was about 5deg. Av consumption on arrival showed 47.
-
That's kind if in line with what I'm getting. 12 mile trip to work. At about 4.5 miles oil registers 50 degrees. By about 7.5 miles I'm usually up to 90 degrees. For me ambient temp doesn't seem to make a difference (have tested with 5 - 10 degrees).
I've made a few more trips to Manchester and economy is just the same - trip down us usually 45mpg. Trip backup is usually 50mpg. I Did a test without using ACC and got my worst mpg ever. Also my long term fuel consumption details seem to have reset themselves. Coming up for 4000 miles but it only shows 800. I'm starting to ignore the consumption now!
-
Well, just got in from my 600 mile round trip. And not quite the mpg i was hoping, but not diabolical!
The route up was a24, m25, a1, then a load of funky back roads to Louth/Fotherby.
Then saturday was Louth across to Buxton, and then down to Nottingham in the eve. And today was the traul home down the m1, m25 and a24.
it read 46.9mpg going up and 47.1 coming home.
I saw a grand total of TWO! other GTD's and no GTI's on my trip. Both the GTD's within 200metres of each other leaving chesterfield towards Buxton. Both Pearl black / or at least a nice black :) - waved at both with no response :P
Twas a great trip. Seem to get a sore left bum cheek after about 150/200 miles, but the second i jump onto the small roads, no pain at all, hehe :)
The car performed admirably, and the standard sound system is great! :)
the drive was obviously mainly on ACC at 70-75... so was hoping for greater mpg, but i noticed, when down to 50-60mph, it did seem to record 50-55mpg in 6th.
Tried with and without ACC, and well, not much difference on the mway.... and no need for it when having fun on the smaller roads :)
Great trip, and now to de-christmassy-fy the house :P hehe
-
Well, my two cents: I'm up to 126 miles now and had my first journey to work this morning in the GTD: 3 miles of 30mph, 6 miles of dual carriageway, a mile of 60, and a mile of 30s.
42mpg for that journey, and I was certainly driving positively..the torque is addictive.
For the transformed driving experience from my last Golf, I'm more than happy with these figures. So much so, that I've taken the avg. MPG out of the MFD menu altogether. I'm going to drive for the pleasure of driving :grin:
I will still keep a track of MPG via my Road Trip iPhone app (I'm a geek after all..), so that I can keep an eye out for crazy low figures..
Happy driving.
-
Down to Manchester again today. Normally get lower mpg on the way down but hit a pretty good 48mpg. The journey backup saw me get 51.3Mpg which is my best on a long trip so far. Ambient temp was between 4 - 6 degrees. Used ACC at a steady 75mph for most of the journey. No idea why the MPG was so good as I have driven it exactly the same as my other trips to Manchester which have often had higher ambient temps but poorer MPG!
-
Full tank first half tank getting great mpg around town and motorway runs. Second half tank very poor. I just give up no I just fill up and go
-
The mpg makes no sense. Filled up at Tesco's and 3 x +100 miles trips all at +50 mpg....last week all 45
-

That quite often happens with me too, first 100 miles or so maybe 47mpg, the rest is between 41 and 45mpg, depending upon whether the DPF is trying to clear itself.
-
Well, today was cold, around 2 degrees celsius, and with 75 on the dual carriageway my commute came out at 38 - and I had my first regen interruption today too, ignition off, lock, and the fan going mental.
Hopefully this isn't my first regen (230 miles on the clock) and others have been happening during the drive?

First regen at 250 miles - sounds about right - most likely it'll be smellier than subsequent regens as that heat peels away some traces of protective oils etc from the exhaust system.
I drove a bit harder today than I have been for a week and got up to 45mpg for my 12 mile commute at 4C, compared to 42/43 for the rest of the week. Driving it a little harder early on does have its advantages of a quicker warm-up (not by much) and better mpg for a longer part of the journey.
-
I often wonder what effect relative humidity has on fuel consumption. Is a dry, low humidity day better than a damp, humid day?
-
I am putting full load on my engine at least once every trip...thinking it will stop the regen....result is better MPH, no regen and big smile :grin:
-
5.5 degrees ambient temp. 52.3mpg on my 11 mile trip home from office. Bizarre I tell you!
-
I often wonder what effect relative humidity has on fuel consumption. Is a dry, low humidity day better than a damp, humid day?
Humid and warm are better conditions for optimum mpg (more so warm). Humid air is less dense than dry air, and warm air is less dense than cold air at any given pressure. As air warms up, it expands, making it less dense in an open system (the atmosphere), or a higher pressure in a closed system (like the engine's cylinders). Moist air is less dense than dry air at any given temperature or pressure because water has a lower molecular weight than either Oxygen or Nitrogen. At 25C, 100% saturated air is about 1% less dense than dry air.
Overall, 100% saturated air at 25C is approx 9% less dense than 100% saturated air at 0C (not that 0C air can hold much water), but the moisture rather than the temp only contributes about 1/10 of that 9%.
So in the summer, with 9% less dense air, that's a hell of a lot less drag on the car as it pushes through the air. Also, being maybe 25C warmer in the summer than in the worst of winter, warm-up time from a cold start could be reduced by as much as 3 miles - on a 12 mile journey like my commute, that's the difference between 4 miles of the journey running optimally and 7 miles of the journey running optimally.
Humidity has a positive effect, but only just - maybe 1%
The air being less dense has no effect on the engine's oxygen requirements for efficient combustion, air is drawn into the engine greatly in excess.
-
I am putting full load on my engine at least once every trip...thinking it will stop the regen....result is better MPH, no regen and big smile :grin:
I find it best to put that load on quite early in the trip and get the engine up to temp quicker.
Just going to work - if traffic permits me to get up to 80mph on the dual carriageway, I'll hit 46/47mpg for my trip and reach 90C by 7.5/8 miles.
Do the same journey and traffic only allows me to maintain 60/65mph on the dual carriageway and i'm looking at 43mpg for my trip and reach 90C by 9 miles.
The longer the commute, the less relevant the warm up phase is to your mpg.

You're loading before the engine is up to temperature MH?
-
You're loading before the engine is up to temperature MH?
When the water is up to temp I do (well 3/4 throttle max, until oil is to temp). I'd be more concerned about getting the oil temp right up if we weren't using fully synthetic oil that doesn't have a drastic change in properties such as viscosity over it's operational temperature range.
Don't forget also that diesel fuel itself is lubricative, so you can push a diesel car harder early on than I would do with a petrol engine without risking excessive engine wear.
-
2400 miles past 1st service and my dad's mpg has not gone up in the slightest, compared to pre-service. He's still getting a consistent 47mpg (better than me, but his commute is quite a bit longer and he does far more miles in the line of duty at work).
-
Maybe we are going to have to admit that we are stuck with poor and random mpg?
-
Who wants to smash out their DPF guts first and map it out??? :p
-
Maybe we are going to have to admit that we are stuck with poor and random mpg?
It will go up in the summer and some will proclaim running in did it, then it'll dip again in the winter. My best chance of increased mpg is ditching these sh!tty Bridgestones.
You'd think that now the VW emphasis on economy and safety (as always) would obligate them to be more selective about what tyres they put on e.g. lower rolling resistance tyres that have decent levels of grip - not much to ask on a £26k car, is it?
If a full set of 4 Michelin PS3s increased my mpg by 10% and lasted 20k miles, they'd contribute £270 towards their £400 costs (Costco costs taking into account the promotional fuel card). Would a pair on the fronts give most of the improvement of 4, seeing as the back 2 are being dragged?

Back on Esso and my mpg is about 7% down on standard BP (getting about 41mpg for my commute vs 44 with the BP at about 2C ambient temp on the way to work, without regens going on. It has been a cold 2 weeks around the North East (and everywhere else), colder than it’s been for a while, and yet the BP managed to maintain the 44mpg average I was seeing with everything else used when the weather was a bit warmer. Standard BP definitely seems to be the winner for me right now.
-
4th tank of fuel is a big drop down to a real mpg of 45.4 and indicated mpg of 48.9. But it did involve quite a lot of motorway cruising at 85ish and I was forced to use a standard shell diesel as apparently there was no stock of their usual fuelsave version. Since filling up with BP Ultimate and the warmer weather I've seen a regular indicated 52mpg so am optimistic that the spring could bring regular mpg in the mid 50s.
-
Eeep..just had my second ever fill up which has allowed me to calculate the MPG, 35.6 actual and 38 indicated. Not a good start for me. Have filled up with BP standard to see whether I see anything better. Would have been better off with GTI! :angry:

My MPG has been down too these past weeks. Struggling to break 50mpg. Think a longer commute helps but my car still seems to love ASDA diesel.

I had been struggling to crack 45, but the last few trips, mpg has been pretty good. Had a run back from Heathrow last week, around 100 miles, and managed to get just over 50, sat with cruise on around 75 for the majority of the way and was really pleasantly surprised. Yesterday reached the heady heights of 58mpg on a 50 mile journey M11/A14/A1. Mostly sat at 65mph because of traffic, 70 on the A1.
I know it's stating the bleeding obvious, but as I've been much more gentle with the acceleration, it makes a massive difference, give it the beans and the mpg falls off a cliff. I have been as low as 31mpg on short journeys and giving it plenty :evil: it's trying to find that happy balance between enjoying the performance and not having to fill up more than once during the week.
Car is 6 weeks old now and just on 3300 miles
-
I was forced to use a standard shell diesel as apparently there was no stock of their usual fuelsave version.
Are there 3 Shell diesel variants? I thought fuelsave was the standard Shell, I have only ever been able to get fuelsave or V-Power for the last few years.
-
I was working in Manchester earlier this week. My trip back to Edin netted me a record 53.1mpg. My 11 mile drive home from the office today got me a 51.2mpg. My drive in this morning got me 39mpg. Don't know what it is but the journey home always seems to give me good mpg.
-
Back up to 45mpg today. It's no warmer than yesterday, but it's not raining and oil temp monitoring didn't indicate a hint of regenning.

I've been trialling the adaptive cruise all this week to see if it much worse or better than me driving manually. Usual trip home from work i.e.
Distance 16.3 miles - Cold start. Car set to Comfort mode in the driving profile (i.e have DCC dampers) and of course the car is DSG.
10-15 minutes from start of crawling at <5mph for the first ½ mile
Onto motorway for 10 miles (cruise set to 70mph) - normally the Motorway is really busy and typically average speeds are around the 55-65mph range, so the ACC manages this speed differential perfectly..
5 miles of 50mph single carriageway followed by the last 0.8 miles of urban 30mph (roundabouts - traffic lights etc).
In the current weather (circa <7°C) I typically get (driving manually) about 50-52mpg.
This week with the cruise set, I've been achieving exactly the same. So whilst it's no better on economy, it doesn't seem to penalise as much as the manual cruise used to on the Scirocco, and with the speeds on the motorways up and down every 500 yards it seems, it does make the journey home much more relaxed and safer.
The only thing I would change is the minimum distance to the car in front, which even set to minimum, leaves a huge gap and invites other cars to keep cutting in meaning the ACC keeps having to slow down and speed up. I appreciate the distance is probably set to a distance that the car is able to brake from without hitting the car in front should an emergency situation arise, but if driving manually, I would normally be at least a third closer and still well behind the car in front and not tailgating (which is a pet hate of mine), but I do feel is a tad on the "safe" side.
-
I've said the same about the acc Andrew and was shot down in flames by the know alls who know best. I've used it quite a lot on journeys and mpg is really good with it.
-
TBH Chris, I wasn't sure myself until I tried it. Must admit, when I first got the car, it did take a leap of faith to trust that the car would brake when approaching a slower moving car (and my foot did hover over the brake pedal on more than one occasion), but I've now learned to trust it completely.
One thing I should have added to the above, is that last night, I change the "individual" driving profile setting to "Comfort" on all settings except, ACC which I set to sport. This meant that when a car slowed me down, when it moved (or I moved out of the way), it resumed it's set speed much quicker than before and felt more natural and didn't impact MPG at all.

There was a warning note on the pump stating that fuelsave was currently unavailable so standard diesel was being supplied. This was on the A14 in deepest Suffolk near Ipswich.

I did this test as well on one of my runs down to Manchester. Got some of my worst mpg's! I find that ACC is just too useful not to use when on long runs.

Back up to 45mpg today. It's no warmer than yesterday, but it's not raining and oil temp monitoring didn't indicate a hint of regenning.
MH - what change do you notice in oil temp during a regen? Would appreciate knowing as I've failed to figure this out. Thanks. :smiley:

When the car has decided it wants a regen before it is up to temp (because it really needs to), you will find that the oil gets up to 80C as quickly as normal (6.5/7 miles), but 80 to 90C takes a lot longer - I assume the DPF is pulling heat away from the engine to forcibly start the process. This is the forced/active regen.
When the car is well up to temp and running above 94C (and I have seen up to 101C), it is definitely regenning. If you are on a journey long enough to satisfy the full DPF regen process, then the temp drops back down to 93C, even down to 90C. This is the passive regen.
-
I drove from the Midlands up to Northumberland yesterday. First 12 miles on twisting B road, the remainder on M1, M18 and A1. Total distance around 225 miles. Decided to set Eco mode for the entire trip, with ACC at 70mph (real world probably 67mph). My average from start was 55mpg, so pretty happy with that.
Interestingly, the return journey in the evening with the same settings and same route only managed 49.5mpg.
-
Is anyone else submitting theirs to Honest John's real life fuel economy register? I try and do this as much as possible:
http://www.honestjohn.co.uk/realmpg/volkswagen/golf-vii-2013
Current averages are 44.5mpg for manual and 43.6mpg for DSG
-
Is that register based on long term, on a single tank or what? Doesn't seem particularly scientific.
-

I submit a tank at a time, the figures on average are pretty close to what I see in the GTD and my Octavia VRS petrol. Agree it's not the most scientific but it seems a good yardstick.
-
OK, might give it a try.
-
Well, it was -2 when setting out today and fully iced over. Sat on my driveway for 5 minutes de-icing before moving off - traffic horrendous and accident on my main route added 10 minutes to my journey.
The figures speak for themselves..

Winter winter go away!
-
Jivemonkey: 5 mins sat on the driveway won't have helped. I deice the windows with lukewarm water and set off. 1C at mine today, usual 12 mile commute on mixed roads and got 44.7mpg (indicated) - not bad.
-
Completely agree, I usually bring a bottle out with me to do the windows, but this was my first frosting with the GTD and wanted to see how the Climatronic handled the weather; good, but not good enough to stop the aforementioned warm water treatment!
To be honest though, I've been struggling to get over 40 since I had the car. One exception being the 45 minute cruise each way at the weekend, at a steady 73mph, where I still only managed 45mpg. Just broke the 1000km milestone so we'll see what's on the other side..

Am finding this thread very interesting.
I have been driving a 1.6tdi Focus for the the last 18 months, but have been brim to brim checking the mpg for almost a year now. I think it would be acknowledged that the Focus with the 1.6Tdi engine is seen as an eco model, but I am finding that your figures in the GTD's are pretty much matching what I am getting.
I did have a remap on the Focus around November, which has neither improved or really worsened the MPG, albeit I now how some more ponies. It does have 18 inch wheels which perhaps saps the MPG slightly, but again is a good comparison to the GTD
Will be interesting to see how the GTD compares when I get it. My work involves me driving as a service engineer, on varied roads, traffic and distances. However, the average style of my driving would be a good test for a comparison.
My point ? Well, given the GTD is a performance model and the Focus is "supposedly" an "eco" choice. The Focus is getting nowhere near the advertised figures and believe me I have driven some tank fulls as economically as is possible in the real world. So, given the MPG between the two, which would you prefer? A wheezy 1.6tdi 115bhp , or a Performance diesel ?
Just posting for a sense of perspective really.

For anyone interested in a technical training document on all things DPF, I came across this document whilst doing some research. Looks to be from a Freelander 2 forum but the same will apply DPF wise.
Thought it to be very useful.

Well over 3300 miles of mixed driving (mainly city commuting to work), the GTD DSG is averaging 46.1mpg (brim to brim), against a car calculated of 46.8mpg (the car average is an "average" of my initial figure - which reset itself after 100 hours driving, and the current value).
Interestingly enough, I played with the individual settings in the car at the end of last week, and changed the Engine from Eco to sport.
Bascially, It's set up thus
DCC - Comfort
Steering - Normal
Engine - Sport
ACC - Sport
Curve Lighting - Normal
Climate control - ECO
On my first trip to work (when I usual average a pretty constant 42-43mpg, I got 46.4mpg ! On my way home from work (using ACC as usual), I usually average 51-55 mpg (depending if a regen is in operation or not). Well my first test got me 61.2 (my best ever) and Friday's run 58.9mpg. It's a massive improvement and a more enjoyable ride to boot.
I'm going to keep these setting here for a while an monitor them, but if it can achieve that at ambient temperatures of typically less then 6°C, I can't wait for the spring / Summer when temps get back up to 15-20°C to see what she will do then !
-
Sootchucker: Have you tinkered much with “Normal” engine setting yet? Didn’t know whether you are one of us that see a 10% dip in fuel economy but a faster pick-up in the mid range (not going into the clicky zone) on Normal vs Sport - it's like they got my 2 icons the wrong way round for those 2 settings. I definitely find Sport no worse than Eco for fuel economy on mine.

Back up to 45mpg today. It's no warmer than yesterday, but it's not raining and oil temp monitoring didn't indicate a hint of regenning.
MH - what change do you notice in oil temp during a regen? Would appreciate knowing as I've failed to figure this out. Thanks. :smiley:
When the car has decided it wants a regen before it is up to temp (because it really needs to), you will find that the oil gets up to 80C as quickly as normal (6.5/7 miles), but 80 to 90C takes a lot longer - I assume the DPF is pulling heat away from the engine to forcibly start the process. This is the forced/active regen.
When the car is well up to temp and running above 94C (and I have seen up to 101C), it is definitely regenning. If you are on a journey long enough to satisfy the full DPF regen process, then the temp drops back down to 93C, even down to 90C. This is the passive regen.
Thanks MH :smiley: Will have a good look now and see what mine's doing.

Managed 49mpg tonight on a 35 mile round trip consisting of 4 shorter journeys, mainly at 70mph. 2 sets of regens were going on - the second leg of 9 miles on a fully warm engine, and the third leg, around 11 miles, also on a warm engine. Temps up to 98C on the second leg, settled down to 95C when I reached the mother-in-law's house and the fans were blaring. Third leg was happy to sit at 95/96C, the odd stoppage at lights with 1000rpm idling and non-availability of stop-start on the third leg confirmed regen was still happening. I was in the early 50s on the second leg, the third dropped it to 49 and it stayed there for the rest of the journey.
The biggest difference between this car and the Scirocco seems to be it's reluctance to run warm generally and be passively regenning all the time. The GTD seems to want to regen in batches, presumably to keep official CO2 and NOx emissions lower on the tests e.g. rather than doing 120g CO2/Km all the time, it would rather have 80% running on something like 109g and 20% (when regenning) running on something like 130g CO2/Km - ensuring that regens don't occur during cycle testing. Running a little cooler reduces NOx emissions, and the limits of NOx emissions for diesel cars have reduced a lot from Euro 5 to Euro 6 standards.
It all seems a bit of a "pull the wool over your eyes" exercise as far as CO2 emissions testing goes. The car isn't combusting diesel any more efficiently to reduce soot compared to the previous gen, VW just ensure that they perform their emissions tests on an empty DPF.

I left work tonight with a cold engine, and after waiting for a minute or two for the heaters to clear the condensation, drove the usual 2 miles to the M1. At that point Since Start was registering 29mpg average. As soon as I got on to the motorway, I reset Since Start and the average leaped to 50mpg. Those cold starts have a major impact on average mpg, more so than on my previous Mk6 GTD.

Yep, the first miles of warm up are by far the thirstiest. If I could just have my car at operatig temp for the whole of my 12 mile commute, i'd be achieving 67mpg. We went through this a while back (on this thread I think) and I broke down the mpg for the first 4, 8 and 12 miles of my commute. Basically the first 33% of my commute uses 41% of the total fuel used in my commute.
-
Interesting. My car is garaged overnight, so there's probably some residual heat left in the engine the following morning, which may help it reach operating temperature a little sooner.

Overnight it'll be as warm as the garage - 8 to 10 hours it will have cooled, you might be talking a 5C advantage at most over someone who leaves theirs outside.
-
Mine has started to regen again, which I haven't noticed for a while. I wonder if it's because I am having to drive it slower due to road conditions? Also, pumped up the tyres yesterday and today's fuel consumption is shocking :angry:
-
I'm shocked how low some of your mpg figures are, I can only concluded that the GTD engine is taking longer to open up. Anybody done over 10k miles yet?

My dad is on 12k miles, had his 1st service at 9.5k miles and his is the same as it has ever been - a solid 47mpg average.

Just after work very short commute back home, I never seem to break 50 mpg barrier for the longest time. My commute mainly consists of some mixture of A and B roads, average speed of 17 mph pretty much tells the whole story.
Don't know what I could be doing wrong but I would love to see 55+ at least once.
-
Find a motorway!
-
Had my first noticeable regen today. Popped into my folks who are about 8 miles into my 11 miles trip home and noticed the fan was still running loud after switching off the ignition. It was off by the time I got back (about 30 mins later). Mpg when I got home was 47.5 - so not as bad as I thought it was going to be.

49mpg on am 8 mile run where the car won't even get warm, in a fair bit of traffic judging by the ave speed, looks impressive from where I'm standing. Get it on a proper run and see what return you get.

I'm with mon2s, mine is a similar commute I'm lucky if I get more than 42-43.

Sounds pretty healthy to me - try a motorway trip and you should easily see low 50's.
-
Well, it was -2 when setting out today and fully iced over. Sat on my driveway for 5 minutes de-icing before moving off - traffic horrendous and accident on my main route added 10 minutes to my journey.
The figures speak for themselves..

Today was slightly "warmer", and the traffic not quite as bad as usual so only creeping along for around 5 minutes. Quite happy with the direction it's going, should do quite well in the summer.
-
After work tonight, took some detour travelled along M3, M25, M4, then couple of A roads. Not terribly cold outside around 6 degrees. Travelled extremely carefully without using ACC as much as I could, just remembering to do constant throttling and here is the result.

Now that's promising, how many do you have on the clock at the moment? There's definitely a sweet spot for MPG lower down the speedo, I see your average was around 30mph but how fast were you cruising? I'm guessing 50-60?
-

About 60mph is the sweet spot for best mpg most driving conditions – fast enough for the engine to be comfortable in 6th gear in all conditions without having to rely on putting a disproportionate amount of fuel in to maintain high torque in any situation to keep you in 6th e.g. going up a hill etc, the engine will be doing about 1650 revs. The air resistance is still pretty linear with speed up to 60mph, after that the car starts to require disproportionately more effort to overcome it as the speed increases. Traditionally 56mph was the optimum speed for fuel economy, but for a high geared TDI, it’s a bit higher than that as I’m sure you wouldn’t take a really steep hill in 6th at 55mph, doing only 1500rpm, you’d end up knocking it down to 5th, but on the flat, 55mph/6th will be great for mpg.
There are times when knocking down a gear will yield better mpg. I find that even though my GTD is happy to sit in 6th to do a constant 40mph, 5th gear is more economical for me than 6th up to about 43mpg on the flat and maybe up to 50mph up a moderate hill. The gear change prompt doesn’t seem intelligent enough to always give you the right answer – it seems to take only gear and speed into account, rather than engine effort in certain situations, although it does seem to tweak the speeds for gear change up when the car is undergoing an active regen.
-
82mph used to be the sweet spot on my old Leon 1.9 fr. used to average high 50's low 60's on a run!
-
^ The old PD engines seem to have constant economy for me - no difference whether you clogged it or drove like a nun.

I left Suffolk Thursday morning with around 70 miles on the odo and drove to Gloucestershire in Eco Mode and ED on the gearbox and it averaged 48.3mpg which I was quite happy with.
Came back today and now showing around 550 miles and drove in Comfort mode with the gearbox mainly sat in 6 manual and it averaged 49mpg.
Considering the engine is still working up and the driving was quite swift there and back - well impressed!
I guess however some shorter trips in Sport Programme could see a significant drop :rolleyes:
-
I'm telling myself to stop worrying about the mpg....or chop the GTD for a blue motion. I got exactly 50 mpg on the way home tonight but bored with the drive. No happy medium maybe?

Keep telling myself the same thing - but the mpg reading on the MFD is hard to ignore. Sometimes I wish it wasn't there - ignorance is bliss!

Hi Monkeyhanger - you have mentioned regen in a couple of your posts. Can you help me and advise what that is please? Sorry only got the car this week and fairly new to the forum. Thanks.

Regeneration of the DPF. There is a multilayered ceramic block (think of it like a honeycomb, but it's structure is more uniform than that) just after the engine manifold, at the start of the exhaust system through which the exhaust gases flow. It collects all the soot generated by the engine and stores it so you don't get that sooty black cloud pouring from your exhaust that can be seen in older diesels.
At intervals the DPF needs to be cleared so the exhaust back pressure doesn't build up.
If you do regular moderately long journeys, the engine generates enough heat for the DPF to heat up and burn off the soot. This is passive regeneration, if you do more than 15 miles per journey then this should suffice to keep the DPF clear, this can't happen until the engine is up to full operating temperature.
Then there is active regeneration. Basically the DPF is loaded with soot to the point where the car tries to force a regen because you persistently haven't met the conditions for a passive regen. It takes steps to force the DPF up to temperature required for regen by introducing fuel into it to burn and generate heat independently of the engine.
During active regen the car is running (in my experience) about 15% thirstier than normal. When the DPF is clean, post regen, the car will be running at its most economical, and it starts to dip towards the point at which regen is required. On my 12 mile commute, I can see 47mpg for the journey when the DPF is clean, dipping down to about 45mpg when a regen is imminent, and 41mpg when undergoing an active regen.
-
Thanks Monkeyhanger - blimey these cars are hi tec - had no idea that was fitted, I guess you have no idea when it happens other than the fuel consumption dip.
I am still getting over using the cruise control today and letting the car have the speed and brakes with me just steering - nearly a week on I must say very impressed.
I'll probably find something else to ask you in a few days - please just humour me !! :shocked:
-
Just filled up today. Took a small risk on range getting the missus to work at 6am, I went 5 miles beyond "0 miles" on the MFD because there were no fuel stations open around me (they all seem to open at 7am on a Sunday). I was literally the needle's width off the white empty line in the fuel gauge.
MFD mpg ave for the tank was 44.1mpg, and actual fill was 46.7L on 450 miles - 44.1mpg. That was on Esso.
For the first time since owning my Scirocco, I have given Shell fuelsave a go. It used to be a solid 4p a litre more than the Morissons 1/2 a mile away, now it's dropped to 1p over (now at 135.9p/L).
On top of that they've got 5p a litre off when you buy 2 certain products. Opted for 2 x 100g bags of mini eggs which ended up adding only 30p to the cost of the fuel on its own.
-
That sounds like a great deal....keep us updated on the fuel save will you?
Alternatively I'm turning the central display unit off and using tippex to show a constant 54.3 :laugh:
-
Set the central display at MPH and enjoy driving the car, if you had ordered the GTI you would end you up averaging around 30mpg whereas the GTD will average well over 40mpg :smiley:
-
Only got my car Friday and in the first 60 miles its reading 46mpg. As its so new there isn't a lot of spirited driving in that but quite a bit of round town stuff so I'm pretty impressed so far.
-
When I got to my car tonight, someone had left me a note saying they had a GTD, what was my MPG like because theirs was really disappointing. So I called them, they said their long term average was 45, it had been into VW who said there was nothing wrong with the car, but they also said that their lease company had arranged for an independent assessment of the car to be conducted over a 2 day period this week. They said they would let me know the outcome... I'll keep you informed.

What an odd experience..but interested to know outcome. Surprised they were going to investigate a long term 45mpg..I'd kill for that.

Could be interesting, would really like to know the outcome of that independent assessment.
I think there are 2 reasons we're disappointed with the GTD mpg.
1. The 20% gains over the previous generation are bollocks, all tied in to the inclusion of the stop-start and it's effect on the EU cycle test results.
2. The MFD is so much more accurate than previous gen. Rather than being 10% optimistic, it seems almost bang on.
Add the 2 together and you get a car that is 30% less than advertised, pretty much what I (and plenty of others) have. If you had a Scirocco 170TDI or a MK6 GTD, with your actual brim fill mpg then you'll probably find you're no better or worse than you were before. For those that never had one, they might be expecting far more out of their MK7 GTD.
It's the people who drive these for work and get fuel reimbursement based on the book combined mpg who are really getting short changed - every mile they do for work is costing them 4.5p in fuel reimbursement shortfall if they get paid on 67mpg and the car is doing 45mpg (a mate of mine was in this exact situation until he bought an old Peugeot 306 to lay on the company miles).

I get my GTD 14 April. I do about 30,000 miles a year and have had 2 A3 140 TDI PDs and currently have a Cmax 1.6 diesel (pram lugger for a few years following new arrival). Both A3s struggled at first to get 45mpg up to the 20,000 mile mark on my 140 mile round trip commute, then loosened up and hit on average just short of 50mpg. The Cmax is averaging about 48mpg on same journey now (at 80,000 miles it is now finally getting some consistency!).
I'm working on the basis that if the GTD hits 50mpg on my commute (90% motorway) then I'll be very happy. About 70bhp more than the Cmax, lower emissions, lower tax, low company car lease rate... oh and infinitely better. What's not to love?
Will find out in April of course but in the 300 mile on the clock demonstrator I had for 3 days it was approaching 48mpg on a part of my regular commute. Anything above 45 though I'll be fine with. The stop start part of the official measurements really does mislead though - I never expect any car with stop start to get near the published figures. My wife's 1 series is miles off the official figures.

Well, my long term average is now at 35.1! Wohooooo creeping up (Nearing 2k miles)

But 1k of my 2k miles have been 3 mile return trips. hoping to improve that soon!

Starting to see where Noobmonkey is coming from........
700 miles on the clock now, 43.7mpg since the beginning (and the beginning was very gentle), 39.9mpg since the last refuel and the first spirited but below 3500rpm drive home tonight (12 miles of mainly A/B roads) and it did an amazing 35.8mpg!! :shocked:
Looking forward now to seeing what some kickdown action and sport mode will achieve at the weekend :rolleyes:
-
As I had to pop home today during my lunch, I thought I'd have myself a little experiment.
I drove home normally and returned a fairly normal 42 mpg; which isn't too far from what I'm getting on myeveryday journey home. For the return leg back, I reset the 'from start' data after I set off, the aim being to see whether the mpg would end up being much different with the engine fully up to temperature right from the offset. You'd think so, right? I'm sure I read someone post that 40% of their journey's fuel was used in the first 10% of driving, or something like that.
Now. I was expected to see something in the 50s personally..but once I parked up, I was only up to 45mpg. A bit confusing if anything, but also a little disappointing. Even with a fully warmed engine, I can't get anywhere near 50, but a cold start run in the morning I'm getting 42/43?! Madness. Give up.
Going to have a nice long run over to Stanstead on Friday so will maybe see how that does, or I'll just stick it into sport and enjoy the ride! :evil:

Over the last couple of days my commute to and from work is around 41mpg over 19 miles.

Hello Everyone,
I just joined the forum. I've been reading about the MK7 and the GTD for while.
I live in the USA and envious of you guys, Getting all the good stuff from VW. I'm on my 2nd TDI Golf this one is a MK6 with the 140hp TDI 6 speed Manual. Big improvement over the 2001 90hp TDI I had. I just wanted to inform you of my MPG I was getting today 18,000 miles on the odometer. On the first leg of my trip I was getting 44 mpg, 2nd leg 49 mpg. That is in us gallons. I believe you are referring to your GTD MPG's in Imperial gallons. So if i'm right about that and if my conversion is correct then in your units I was getting 53-59 MPG. Does this sound about right?
I keep drooling over the photos and lists of specs that are posted. If all goes well I may have a chance to join in on the fun in 2015 when VW is supposed to bring us the GTD. I tried to get my dealer to order a MK6 exactly the way I want it, Every option but without the sunroof. He said that he could not do it. We have 3 options 1st no sunroof, no backup sensors, no GPS. Still nice, 2nd GPS must have sunroof , 3rd add some more tech.
Back to my question, Imperial Gallons?
The conversion I'm using is 1 us gallon is .83 of an Imperial gallon.
I think I would like the DCC, Damper computer Controlled?
We most likely not be offered that, but if we do, Yes/No?
Well enough rambling for now, looking forward to more GTD post
Mark

-

Given that there was a thread on here a while ago where a significant proportion of those who specified DCC could not tell the difference between settings then £810 ($1250 ish) might seem a steep premium over the standard setup which offers a fine balance of ride/handling...
In the end, only you can decide whether it is worth it...
-
Wiz: Your mpg conversion figures are correct.
As someone who has had DCC on their last car (albeit the first generation, on my Scirocco), I do not miss not having it on my MK7 GTD. Ride composure on the MK7 is a big improvement over MK5/6.
No idea whether some or all of the options we get here will be available in the US, that may well depend on whether US market GTDs are built in Mexico (and whether other models built at the same plant have the same options available) or whether they'll come from Wolfsburg.
-
No news from the strange note leaver ... I'll give them a call tomorrow if I get 2 minutes. I've the car set on individual mode the same as MH's (I think from memory it was you MH) my strategy over the last 2 days was, in traffic change at 2000 revs, on the open road drive it properly, result is 48 to 51 mpg.
-
I managed to give the GTD a good work out yesterday on mixed A and B roads and had Sport mode activated.
Very impressed with the performance and it sounds amazing in that mode. The fuel consumption was also amazing returning 32.6mpg :shocked:
Think I will turn off the mpg display in future and just enjoy the car and put some fuel in when the light comes on.
Btw I have DCC and do notice quite a difference on each setting, comfort is smooth and Mercedes like, Normal is firm and Sport is bloody firm! :smiley:
-
So, passive regen yesterday morning so I decided that I might as well take the power. Floored the car a couple of times when travelling up step hills, and I mean past the point of the "manual" kick down and hey presto, 54 mpg today! #confused.
-
That is very impressive Gordor !! I have not dare look again since the weekend :sad:

Can't complain with that!
I filled up again today and my last tank worked out at 38.8mpg (Indicated 39.5mpg)
-
For the last 3 days I've been doing another little test with my normal trip to work and getting on average around 45mpg, the only change I did was set the climatronic 'auxiliary heater' to disabled in the setup menu.
I can honestly say I didn't notice too much of a difference with the time it took to heat the cabin, and the heated seats really help it feel more warm than it is anyway. To see whether there would be any significant difference I thought i'd enable it again this morning. Got to work and MPG down to 41.
I didn't go as far as checking ambient temperatures each day but it's been fairly consistent around 5 degrees the last few days. Can only attribute the loss of MPG to the heater...anyone else tried this? I believe it draws around 80A when active and doesn't turn off until the oil temp reaches 70 degrees.
-
Hmmm. Will have to try this!

So 80A on a 12v system is about 960watts - the total output of the engine is 135kW... of which in normal driving you might use on average say 40kW. 960w is 2.4% of the average power you use... Even assuming that the auxiliary heater is on all the time (i.e. your journey is short enough for engine temp not to reach 70C) then you should expect to see no more than 1mpg difference.
That's a fairly rough and ready calculation but I suspect the cause of the change lies somewhere else... passive regen, possibly
-
Made no difference on the way home! But it was with a different tank of fuel.
Anyone compared jet to shell?
-
Out of interest (probably me being completely stupid) how do you disable the heater?
-
Not used Jet yet, but i'm almost at the end of my Shell fuelsave tank and it looks like it's going to be around 43mpg actual. The response of the car seems a little laggier than normal when you first put your foot down from lowish revs but after that initial lag the car responds very well. The car's mpg has been generally ok, except when the regens have happened. On Shell, the regens have hammered my mpg, giving me around 36mpg for the regen affected commute, when Esso or BP would have dipped to around 40mpg.
For my experiences I would have to recommend BP standard diesel highest for overall mpg and response/performance, followed by BP, Sainsburys, Shell fuelsave and Shell V-power. Apart from the V-power (41mpg), there hasn't been a massive difference in overall tank mpg between them (43 - 45mpg), and I have yet to do a really long journey (>100 miles) in my GTD.
Anyone else have a "favourite" fuel?

For the last 3 days I've been doing another little test with my normal trip to work and getting on average around 45mpg, the only change I did was set the climatronic 'auxiliary heater' to disabled in the setup menu.
I can honestly say I didn't notice too much of a difference with the time it took to heat the cabin, and the heated seats really help it feel more warm than it is anyway. To see whether there would be any significant difference I thought i'd enable it again this morning. Got to work and MPG down to 41.
I didn't go as far as checking ambient temperatures each day but it's been fairly consistent around 5 degrees the last few days. Can only attribute the loss of MPG to the heater...anyone else tried this? I believe it draws around 80A when active and doesn't turn off until the oil temp reaches 70 degrees.
So 80A on a 12v system is about 960watts - the total output of the engine is 135kW... of which in normal driving you might use on average say 40kW. 960w is 2.4% of the average power you use... Even assuming that the auxiliary heater is on all the time (i.e. your journey is short enough for engine temp not to reach 70C) then you should expect to see no more than 1mpg difference.
That's a fairly rough and ready calculation but I suspect the cause of the change lies somewhere else... passive regen, possibly
Something else to remember is that unless you've got temp and fan speed maxed out, you're unlikely to be drawing anywhere close to the 960W. I mainly have my cabin temp set to "LO" when it is above freezing, so i'm rarely drawing on the auxillary heater. I wonder what the current draw of the heated seats system is when you've set them to "toasty".
Maybe when the car is up to temp, not using the heaters actually has a negative effect on mpg, because the cooling system is working hard to shed excess heat rather than using it to heat the cabin ventilation air.

As I've said before, for me, best results have been from Asdas finest*
*read cheapest.

It has been mentioned on here before but early into your journey, you can make the stop start operate when at standstill by turning the heat temperature down. I'm on Sainsbury's, with MH's settings (also mentioned before) operationally, flooring it properly when I can but then changing at 2000 revs when driving normally (which is a lot at the moment as I work in Somerset if you have seen the news) last few days plus 50mpg, best ever. Mileage is 9500
-
Up to 3.8k now, filling up with nothing but BP Ultimate, from a mix of motorway and rural roads/traffic last tank managed 42 mpg :undecided:
-
Back on the Esso - never realised how laggy the car was on Shell until I pulled away from the Esso station after filling up. Getting tempted by the tuning boxes again.
-
Another trip up to the North-East yesterday - a little over 200 miles via M1, M18 and A1(M). Left it on Eco for the whole trip and ACC set at 68 (65 real world). Arrived at destination with Since Start at 60.1mpg. Temperature was around 7.5C. This is closer to what I could achieve on my Mk6 GTD.
-
Just over 2,500 miles on my GTD. Out on Saturday for 110 mile round trip and the average MPG was 56.4. Very happy with this after coming from a car which averaged 26MPG! :laugh:
-
well i've just hit 2222 miles :)
Overall average is 37.7 (so creeping up from my disastrous start!)
The best i've met on a normal trip is 56.8 (250 mile trip), generally i get 37-41 now on my trips. A 38 mil round trip on saturday managed 42.1 -.
I've tried BP Ultimate, Esso, Tesco and Sainsburys. BP seems the better from that poor selection! :P
-
For some reason, my Long Term figures reset themselves last week. Anyone else had this? Would an inadvertent press on the "OK" button have caused it?
-
I reset my accidentally the other week too. For one reason or another I had the MFD display on 'long term' for all the average readings (speed, MPG, journey time etc) and forgot about it. After refuelling, I went in to the MFD and reset the figures, thinking it was the 'since start' figures, with a prolonged press of the "OK" button - and they were gone! Damn! My since start weren't far of the long term so wasn't immediately obvious..
Oh well. I track the MPGs on Fuelly as well as a cracking little app called Road Trip (I've done this for every car I've owned, including my XJ6) so not a complete failure..annoying more than anything!
-
Annoying, yes! I suspect that it would have reset anyway when it reached 9,999 miles or similar. And one more question on Since Refuel. It cleverly resets on filling the tank - sensor in the tank or opening and closing the filler cap??
-

I assume that there is just a threshold that the fuel level sensor has to increase by to then count as a refuel..

I think it resets automatically after 100 hours or a certain number of miles (can't remember exactly - maybe 3000?)

Sorry if you've already seen this article, but I thought it was interesting to see the range of differences between "official" and "real world" mpg reported across some other models/manufacturers.

OK, back to the MPG...
Manchester and back yesterday 125 miles each way...
On the way there (all motorway except for the first 7 miles and the last 7): 52.7, cruise set at 78 (real 75) normal mode - traffic mostly quiet except for about 4-5 miles on the approach to Mcr.
Return, 55.5 (in ECO mode), cruise set to 78 again, traffic heavier (average speed approx 10mph lower)...
-
Sounds good to me. I'd be happy with that.
How did you find the comfort? I can't seem to get the right seat position and always getting the odd twinge in either my left leg or lower back..
-
I've said it before, in another thread on here, but it bears repeating.
The one major way in which I found the current 120d M-Sport to be better than the Golf GTD was in the driving position and seating. The M-Sport seats are excellent and the amount of adjustment means that the perfect position can be found with a little effort.
In the golf I have found that the seats, whilst acceptable in terms of comfort, are not adjustable enough for me to find my ideal driving position - the seat bases are too high even with the seat set at its lowest. So I can be comfortable but still feel like I'm perched in front of the steering wheel...
Having said all that, the Manchester trip caused me no twinges...
-
Tested the reverse of this discussion. Managed 6.9mpg over a 2 mile trip! ... (Private roads... hehehe) :)
-
Interesting views on seat comfort, which obviously does have a bearing on mpg. Possibly. With my previous Mk6 GTD, I found the perfect driving position, and hated it when a technician moved the seat during a service. On this car, I can't seem to find the perfect position. Close, but not perfect.
-
34 mile trip last night, DPF spotlessly clean (car's oil temp unwilling to go higher than 91C for the 2nd half of the journey), and this morning's 12 mile commute with unremarkable circumstances at 5C was 48.2mpg instead of the usual 44mpg. Having a clean DPF does seem to be key to getting good mpg (and longer journeys a few times a week help keep it that way)
-
Completely agree. At least my latest figures would support your theory.
Two 90 mile trips at the weekend (the first having a large amount of full throttle accelerations) and I can only assume the DPF is spotless. Today and yesterday saw my MPG for usual daily commute raise from low 41/42 to 47 today and 46.5 yesterday.
I noticed also that for the first half of my slightly more tamed return journey at the weekend, on level 50/60 roads, I was seeing over 51mpg and higher. This of course dropped as soon as I got a bit restless but still ended up with 49mpg for the entire journey.
Coming up to the 2000 mile mark and engine definitely feels to be loosening up. Perhaps this is attributed to my latest figures.
-
I've seen a marked improvement in my daily commute over the last couple of days - into the low 50's after the motorway section compared to high 40's last week.
-
Like jivemonkey, a slight dip was experienced vs yesterday - 46.9mpg. The car still feels more sprightly than is the norm. Maybe it'll dip gradually over a few days until either I go on another long journey, or a regen occurs. Again, for the whole way to work the oil temp stayed out of the regen zone.
-
Ok guys.....my nervous wait to see what mileage I will get is over.
- Delivery yesterday - 8 miles on the clock.
- first real journey today Erskine to Edinburgh - my daily commute (53 miles). 49.9 mpg, driving fairly mixed but mainly motorway but 3 lots of extended stop start. Sport mode selected. Didn't push performance beyond about 75. Suspension pretty rigid.
- return journey - 52.7 mpg this time in normal mode. Average speed tho well down on the morning journey. Lots of stop start. Suspension definitely more pliant.
Overall, pretty chuffed. Previous car was BMW 520d, with average around 52/53 over the same journey.
I will keep an eye and post again soon.
;-)

8 mile trip home tonight from the city centre, 75-80mph on the coast road - 49.2mpg. The warmer weather is probably helping, it was 8.5C.
Now I can't help thinking about spoiling it all with a box.

Boxes are tempting me too. Think I need the extra power...

9.5C today, stuck behind a procession of cars doing 22mph on a 40 road for a good few miles of the journey and still managed 45.5mpg. Had to fill up and the penny has finally dropped for the local JET station (usually 3p more than everywhere else, now as cheap as anyone).

A bit of a twist on the mpg banter with the DTUK box addition. I filled the car up this morning so I can see how the box really affects mpg:-
168.7 miles covered, 18.78L used = 41.1mpg, 44.3mpg indicated. Overall 168.7 miles, MFD is 7.8% optimistic.
Prior to box fitment, car was reading 41mpg indicated at 105 miles. Probable 40mpg actual (assuming MFD is 2.5% optimistic, as is usually the case) = 2.625 gallons/12.02L used.
6.76L (1.48 gallons) used to travel 63 miles since the box was put on = 42.6mpg actual.
A 3.3mpg indicated improvement (44.3 vs 41) since fill up on 63.8 miles since box addition = extra 8.7mpg weighted for the 63.7 miles only.
42.6mpg actual + 8.7mpg (indicated improvement) = 51.3mpg probable indicated had the car been full from the box addition. Car is 20% optimistic on the MFD display vs actual.
That's fine, as long as I look at the MFD and know that if the computer is reading 52.8mpg, I got 44mpg. The box isn't for me to get improved economy. The extra torque might help economy (a little) for motorway cruising, but around the doors I don't think it will.
The above calculations are all a load of extrapolation on mixed circumstances.
I filled the car up this morning so I can get a proper MFD vs actual when I use a tank full of fuel.
Early indications prior to adding the box and after are that Jet fuel is sh!te for mpg. I will be sticking to Esso and BP in future.
-
Yup,
I have noticed that on my current car, the MFD readout was pretty close to the real world MPG. I have had a superchip remap though and it has made a larger margin of error.
52 mpg pre-remap would be around 49mpg real
52 mpg post-map is around 44 mpg real.
Something to bear in mind when reading reviews of peoples mapped cars. Unless you are doing brim to brim checks, the MFD readout cannot always be consistent between mapped and non-mapped. Perhaps explains some reports of mapped cars having improved MPG with better performance...
Not sure why this is though.
-
Karlak: The MFD is calculating fuel economy based on what it thinks it is consuming. Actual usage when then the box is taking the fuelling signals and amplifying them (over what is essentially a 2D map, if I understand it right) is higher. To main 70 mph with the box on takes less press on the throttle pedal than without. The MFD interprets this as needing less fuel and so you get a higher mpg reading. Actual mpg will be the same (unless some marginal torque gains come into play).

Ahh,, I see.
When I mentioned this to Superchips, they said they could alter or do something the map to account for the change in MFD reading. Mine was the first car they had done, so they were on a bit of a learning curve with my model.
I never went back to them as I had pretty much decided to order the Golf anyway.
Just for information, they were very interested to "get hold" of a Mk7 to try and get a map sorted. They did this on my current car, so you basically get a remap for free. I already had the Bluefin, so they just adapted for that my current car.
-
Right I have had the mk5 GT Sport and and the mk6 GTD. Waiting for my mk7 gtd
I have driven the mk6 with and without the DTUK tuning box. I can say that I found an increase in mpg especially when I drove from Cornwall back to London. Yup I was a dummy fitting the box to the mk6 in Cornwall when we started having all the bad weather lol.
Once installed Jesus you can feel the difference in the car straight away. The mk6 went to 65mpg that was driving at a constant speed for a long period of time. It does work if your frugal. But when around town I actually used a different map on the box so the power delivery was smoother and had less of a bang right at the start. This was better around town. I still think I will take Andrews offer and get the box changed and setup for the mk7 without fail. My mk7 has just over 8000 on the clock so am hoping it's already sorted its mpg side of things out. But seriously can't wait for the box to be added.
I'll definitely give the normal side of the car a try first without then with the box. But on the test drives that I did I did notice the 5th and 6th gear were a little flat compared to both the mk5&6. But hopefully the box will cure this issue.
Has anyone tried the Pedal box? Instead of having the extra grunt from the tuning box. Why not just try the pedal box instead as it doesn't increase power on the car.

Drove back up from Manchester to Edinburgh today. Got a respectable 52.7MPG. Two turns away from home the car started a regen. Revs at 1000 and stop start not functioning. Got home and switched the car off and the fans were still running. I'm amazed that during a 225 miles / 4 hour journey the best time it could find to regen is when your back on a normal city road and about to end your journey!
-
3623 miles in and long-term is 47.1 mpg
-
Getting a lot of drag from those mudflaps. :wink:

Me too. Been on an 80 mile round trip, with oil temps generally up in the 98 to 102C for the vast majority of the journey. I would imagine that the DPF got hot enough for plenty of passive regenning which could have emptied the system, yet the fans were blaring when I got home, despite the oil temp settling back down to 92C.
The question is then....does the fan continuation always signal the static continuation of an interrupted DPF regen, or perhaps after an extended motorway run, could the DPF be clear and the fan is kicking in purely to cool down the DPF to protect it from overheating after the car has stopped? I'd like to think that this is the case, otherwise it would seem that by design, despite perfect passive regen conditions, VW has set the car not to take advantage of the situation, but makes the car regen at set intervals or set loading thresholds. This could also explain stop-start being disabled - if the fans need to be blaring to cool the DPF when the car is static, there is probably no economy advantage in allowing the engine to switch off and have the fans blaring instead, therefore stop-start is disabled.
I can't at this point tell what my DTUK boxed mpg is until I fill up, but current gauge readings would seem to indicate that actual mpg isn't a million miles away from MFD indicated mpg. The gauge was reading exactly half a tank (from full) when I hit 245 miles done. From experience, 1/2 a tank indicated is a little more than 1/2 a tank consumed. I normally do about 225 miles on an indicated 1/2 tank to get an actual 43mpg. My educated guess on current actual mpg to 245 miles in, is around 46.8mpg, although that has been bolstered by my mid range run, so it will drop again as I do a week of commuting to finish the tank. The indicated mpg for the 2 x 40 mile legs was 51.3 outbound and 53.8 on the way back.
-
Similar experience a couple of weeks ago. 200+ mile run up to Northumberland without stops, pulled into the drive and the fan kicked in and ran for around 5 minutes.

I really do think that on a run like that, there's no chance the DPF isn't clean as a whistle, but the car needs to cool down the DPF system - it probably retains heat a lot longer than the rest of the engine system without a cooling intervention.
-
Finally, on my 25 mile commute home yesterday of 25 miles - a mixture of a roads, town and a smudge of dual carriage ways - I saw 54mpg. 2000 miles on the clock, so
It's seems it's finally getting better.
-
My GTD DSG has now done 5,500 miles, the fuel consumption is terrible, far worst than the BMW 120D Msport auto it replaces; I haven't seen over 50 mpg on any journey, typically it runs at 40 -42, long term is approx 40mpg, not what the car was sold on. Car has been checked over by VW, nothing out of ordinary.
How can all car manufacturer's get away with this false advertising?

They're all at it. Since the inclusion of stop start, it is a huge part of the skew from real life results to EU testing cycles (how many of us here spend 24% of our commute waiting at lights/roundabouts?).
Compared to previous gens, the length of time taken to warm the car up to the point that the DPF is actually able to burn captured soot is longer. If you're not doing 15 miles each way on your commute then you'll see the active regens influencing your mpg negatively. 40mpg overall average isn't suspiciously low to indicate fault. For me on a 12 mile commute, I generally see a 43/44mpg average, not driving like a nun. It can get as high as 47mpg for the same journey if I have just seen a regen recently, or if the weather is a little warmer. Longer (40 miles) journeys maintaining 80mph, I can see about 53mpg indicated.

Im not convinced - I think the cars doing regens at weird times. The last 40 miles of my journey backup are off the motorway on the A702. There are roadworks on this at present. When I stopped here the stop/start worked as normal!
-
Damian - how do you know its re-generating?
-
I've only done 200 miles and also have had a DPF regen for sure, it came very early on in the first instance.
Stop start can stop working for other reasons though.

Finally managed to crack a plus 50mpg journey yesterday and in parts I wasn't hanging around either. Lockerbie to Sunderland via m74 > a69> a1 etc average speed 55mph end average mpg 52.4. I got 48mpg going up early yesterday morning at 2°c but temp was a positively balmy 10°c coming home. I also think that without the short bursts of overtaking it would have been nearer 60mpg but once you put your foot down you can't help leaving it down for just a bit longer :grin:

That's about what I did on a North Shields to Hartlepool round trip on Saturday (indicated) - that temp difference really seems to make a lot of difference to the mpg on the MK7. Who knows what the car might've done without that 110mph spurt. :whistle: Doing more than 15 miles on a single journey does make all the difference. My car will need filling in the next few days, so i'll know what effect the DTUK box has had on my actual mpg. Right now its at a single graduation below 1/4 full, with 370 miles done and the range reading 90 miles left.
-
Getting a good mpg is addictive but watching the speedo climb effortlessly is even more addictive. Love the torque in the GTD. God knows how good it is with a box on like you've got Matt. Think the warmer weather is helping the mpg, although it seems a bit random too.
Mine has been down the last couple of days to 49mpg then today on same commute it's up to 51. To be fair I'm happy with my mpg in comparison to the performance of the car. Massively under what is advertised but I love my car too much to be too annoyed.
-
I agree kyle not many cars can sit at 90 and still return 50 plus mpg's. It's just trying to stop the little devil on your shoulder egging you on instead of easy driving haha :evil:
-
The last few days have been really good with the warmer weather. Today I managed 51mpg (indicated) on my commute driving sensibly (no opportunity to do more than 70mph).
Last night though, on my way back from Newcastle me and an old shape Focus ST (221Hp/320Nm) were having a bit of fun for a couple of miles (the road was empty) on the coast road – definitely noticeably (but not hugely) quicker than one of those without even getting into the clicky zone of the pedal. Despite the spirited driving, I still returned an indicated 49mpg.
I will be filling up tomorrow. The range is saying 60 miles left, the gauge is just into the last white increment on the gauge, and I’ve done 398 miles on the tank. Indicated mpg for the tank is 47.8. I’d take a guess that the DTUK box has made my indicated mpg somewhere around 5-7% optimistic, from around 3% optimistic. I’ll know for sure tomorrow. This by far the most fun tank of fuel I’ve had with this car so far. Been watching the fuel gauge closely and I’m surprised how linera it seems to be in the white zone. Excusing the fact that the needle doesn’t move from full for the first 50ish miles, it seems to move a consistent single increment every 10 miles, or a consistent 1/8 of a tank every 50 miles.
Kyle, the car is phenomenal with the box on – it’s like the throttle is on a hair trigger, and the car responds accordingly, in every gear. I find the Devil on my shoulder a lot right now!
-
So I have had my GTD since Tuesday, I now have 200miles on the clock and I am getting at least 50mpg permanently. Seems a lot more than what other people was getting from new?
I haven't noticed it regen yet, but not 100% sure how I will tell, just been judging it whether the star/stop works or not. Any more obvious indications?
As you said Kyle the torque is superb, all the time you can just feel the power underneath your foot, but it is so hard no to just put my foot hard down and see what it can really do as I am only still in my running in period... :sad:

Dan:
Your 50mpg might be one of a few things – the weather has warmed up a bit and everyone is seeing better mpg as a result. For the last week or so, when the temps have gotten up to 9 or 10C, I have seen my car get 5% higher mpg than when the day has started at 1 or 2C.
Your commute plays a big factor – the shorter the average journey, the lower your mpg is likely to be. Around 0-2C, my car is taking about 4 miles for the water temp to get to 90C, and about 8 miles for the oil temp to get to 90C. Doing less than 8 miles a day, your car won’t be fully warm by the time you reach your destination, the car is running much less efficient when cold and soot generation is higher, which will fill your DPF and force regens. I have a 12 mile commute, and I have noticed a huge improvement in mpg and regen frequency when I up my miles a bit. If you do 15+ miles for most of your journeys then you should be seeing 50mpg indicated, even in the winter, and most of your regenning will be getting done passively.
Your first regen will stink, it’ll smell like your car is on fire! Most people get their very first one at about 200-250 miles, and then it seems to be anywhere between 200 and 500 miles thereafter, depending on how short your journeys are (and therefore how quickly you’ll fill your DPF) – your car will idle at 1000rpm and not the usual 800. There are other things that will prevent stop-start working, related to battery load. If you’re at a standstill and you’re using your heater or aircon more than a smidge (or heated sets etc) whilst the dipped beam is on, you will usually find your stop-start not kicking in unless the battery is at a very high state of charge (90%).

There are other things that will prevent stop-start working, related to battery load. If you’re at a standstill and you’re using your heater or aircon more than a smidge (or heated sets etc) whilst the dipped beam is on, you will usually find your stop-start not kicking in unless the battery is at a very high state of charge (90%).
Cheers for that. Currently doing 3mile journey each way to work with morning temp being between 4C-8C and evening 10C average and back and mixed driving around at night for a good drive. Not been looking at the oil temp yet, will have to keep an eye on that. I will expect for the first regen to happen when my Mrs is driving then and I get a phone call to say it is on fire :grin:!
I also noticed in the 40 thousand page manual that the new engine run in cycle is up to 1000km and to gradually hard run it in between 1000km-1500km. I though that was quite low as it only equates to 621miles. Thought it would be at least 1000miles...

Dan:
3 miles to work each way and you’ve not had a regen yet? I’m amazed, unless your other driving is long enough to keep the DPF clean. Running in really isn’t much of an issue any more with tighter manufacturing tolerances etc. Just drive it normally, babying the engine is as bad for it as hammering it while it is running in and after 1000 miles you can do what you like to it. I ran a TDI in badly once (picked it up from a broker and drove it on a 700 miles round trip all at motorway 6th gear cruising. That car had a thirst for oil, the mpg was crap and the power seemed on the low end of expectations for the car (Golf MK5 140TDI PD). The first 300 miles are most important from a safety point of view because it takes that long for the brakes and the tyres to be scrubbed in properly and working to their potential.
If you haven’t read much of the other threads, you might not be aware to avoid Shell V-power like the plague. It’s expensive but makes the car around 10% thirstier and less powerful because it’s got a lower density than regular diesel. The only thing it has going for it is that it’s clean (as fuels go) and might see you regenning a little less often. I’ve seen best mpg results on standard Esso and BP.

Some really interesting reading in this thread. My GTD is due in around 8 weeks. I've ordered a Tornado Red 5dr with manual 'box and am changing from a 2006 MK5 GTI which I have owned from new. Sadly I've had just about enough of the 22mpg average that the GTI returns and chose the GTD hoping that I can achieve a better balance of performance and economy. It's certainly encouraging to hear that the GTD can put a smile on your face but still do the economy thing well too.
-
Scored a record 56mpg on 12 mile trip home from work this evening. Has to be the milder temp.
-
Last night though, on my way back from Newcastle me and an old shape Focus ST (221Hp/320Nm) were having a bit of fun for a couple of miles (the road was empty) on the coast road – definitely noticeably (but not hugely) quicker than one of those without even getting into the clicky zone of the pedal. Despite the spirited driving, I still returned an indicated 49mpg.
Funny you had a go with an old ST. On mg way to Hartlepool the other day I had a go with one and it rinsed me good and proper. Think a box is necessary, once I get my 10k out the way think it'll be going on.

How soon will your 10k be coming? My box went on at 5k. It was a friendly little challenge with the ST. We each had a blast from 70 to 90 in turn (4th gear for me, I assume he did the same), twice to see how quickly we could put distance between each other, then did one together. I was a few car lengths ahead of it. I'm sure he knew it wasn't a regular GTD after the first time. Blinked his hazards once before turning off for the A19 after our maneuvres.
The box is absolutely great, the extra go feels absolutely natural, like it was always meant to be there.

I reckon it'll be at start or middle of next month. Save a few pennies then put it on and get it lowered. That's the plan, it'd be nice to work out like that haha. My "play" was straight off a roundabout and then a 50-90 burst. Both of which he was easily out pacing me I'd say.
-
No doubt you know this from the know-it-all forum (overclockers) that not only are his statistics more favourable in standard trim, but the Volvo lump sitting beneath the bonnet of that Focus ST responds well to tuning and offers silly statistics for relatively little money. A tuned one would play with you like a kitten with a ball of wool.
I'd say pick your battles personally! I can't pick any as still running in. Desperately wanted to rinse a BMW last night.

I can well imagine if it'd of been tuned the result would of been even worse. If I'm honest I didn't really know the power of the STs. Thought they were in the 200BHP ball park. I'll be more careful in future! :laugh:

Yep, the Volvo T5 lump has great potential, and my GTD is realising its own potential right now with the box. VW seem determined not to try harder with the TDI. They could seriously maim the GTD or GTI sales by going one of 2 ways:-
Bring out a twin turbo GTD with 220-230PS - GTI performance (if they can overcome stand-still traction issues) with TDI economy or
Up the GTI fuel economy by utilising ACT on the GTI lump - GTD economy (or close to it) in a GTI
My mate has a 1.4TSI ACT A1 and finds it very hard to do under 45mpg in most circumstances.
-
I think Volkswagen should drop the GTD in favour of a GTI with ACT :drool:
And for the next Golf R, add VAQ to both the front and rear axels. :cool:
-
Yeah, yeah...
As for the twin turbo - I'm sure you mean bi-turbo - idea there is litle that can be done about the traction issue whilst remaining front wheel drive... four-motion? But I doubt it will happen... VW have been able to build a EEC VI compliant diesel with > 180bhp... would it be possible with a bi-turbo diesel with an output of ~ 230bhp... if not I doubt that they'll do it.
Back to economy... just clicked over 4K miles on the last fill (based on data in Road Trip app):
From new: 4191 miles
Overall Average: 46.10
Worst between fills: 40.63
Best between fills: 50.24
Vast improvement over the last month (last 2000 miles) from an average of 43 in the first 2000 miles - last five fills worst... 48.58.
No obvious change in driving style that I'm aware of, perhaps average journey slightly longer...
-
Corgi: Yep, meant a twin scroll set up. VAG seems to be avoiding it in all but the 3.0 lump, but they are squeezing more out of the single turbo 2.0 unit. The A6 now has access to a Euro 6 compliant 190PS/400Nm variant (the A6 seems to get access to all the best stuff first).
Are your mpg figures indicated (MFD) or actual? We might be seeing small gains due to the weather. The last week or so has seen plenty of 9-12C ambient temp around the country which might see 3-5% gains as we normally expect to see 10% better mpg when the ambient temp is up in the 20s rather than around freezing.
-
Actuals, I use the Road Trip on my iPhone

As a former ST owner, I had mine mapped to 276bhp with just a dreamscience box. The car was blindingly quick and not much passed me when I had it. Maybe when I get some more miles on the clock, I'll consider the tuning box, seems like the GTD was meant to be like this from the factory.
-
Currently at around 35000 miles and just updated my fuelly with fuel receipts.
Averaging 39.1mpg, it does look like each fill is increasing slightly.
Hopefully things will improve when it gets warmer, still sub 5 degress on the way to work and sub 10 degress on the way home.

The extra power feels completely natural with the DTUK box. Lots of power smoothly delivered, and with no appreciable fuel penalty if you're not driving like a maniac all the time (although it is tempting to do so).
I’m convinced that my car is operating a little hotter than stock, more like the Scirocco did (preferring the oil temp to be around 95C more often), and so far the car seems to have a better relationship with the DPF as a result. No active regen for 500 miles so far – that’s a record for me, and it certainly helps the mpg.

whats the difference with your insurance. Pm me Matt

A spirited drive home tonight from work which is about 12 miles in 7.5C, in Normal mode and gearbox in Drive resulted in 34.6mpg.
I went to Heathrow two weeks ago and drove fairly steady in Eco Mode and only got 46mpg. My last car - a BMW 325d Auto (3.0 litre 6 pot engine) bettered this.
Great car - just not impressed with the fuel consumption.
-
Right here's my latest - just covered 700 miles in 2 days, 1st tank netted 500miles and the mpg was being reported at mid to high 50's - I think this is as good as it guys lots of motorway miles sitting at 70 mph.
-
Picked up my GTD today - first longish drive in normal mode along A roads and dual carriageways, a little city driving (not driven hard as still running in but not trying to hyper mile or anything).
76 miles, ave 41 mph, 56.4 mpg. Well happy with that!
:laugh: :smiley:
-
Picked up mine on March 1st. Love the car, its a big step up from the mk6. But my long term fuel consumption is 39MPG and ive not been driving it any differently to my mk6 and that did around 48MPG. Not very happy with that to be honest, i was hoping it would do at least 45MPG. But it is brand new so hopefully it will improve once its done more miles.
-
MPG has taken a real hammering for me coming into work. Has been an easy 47mpg (indicated) over most of the last week (7-12C), today was -2C and I managed 41.7, driving like a saint.
This GTD seems very sensitive to temp changes on the fuel economy front.
-
Seems to be quite a variation lately, and it's almost certainly due to ambients (Edit: Monkeyhanger got in there before me). I use mine a lot in town in the mornings to drop off the mrs so my long term isn't great, but did 55 miles of b road and some a road driving last night for the hell of it and achieved 49.2 which seems ok, although the car has only done 450 miles so i'm yet to drive it enthusiastically - it seems thirsty when you go for the throttle.
As soon as there is talk of a DPF delete I shall be partaking in that. I am intrigued by the long term tuning box findings tbh, as the subsequent hotter engine temps seem to defer the DPF regens well enough which is ultimately what's raping us all of MPG.
I'll see what figures she throws up on the drive back to Peterborough tomorrow as my 270K 306 happily achieved 50 on that run with past their use-by date injectors. My colleague at work is achieving 57 on his 36mile round trip work run with his Mk6 GTD (30k on the clock) with a mix of roads and spirited/cruise/overtakes so i'm feeling a little cheated atm. Hopefully it will settle in as the miles increase a bit.
-
It's now an mot fail if you remove the dpf so beware. If it's meant to be on the car it has to remain on the car.
-
Yes it is, but it is also not within the remit of the tester to remove any undertrays to gain access to perform the visual inspection!
I've never taken my Cat off all my petrol cars, honest...
-
MPG is definitely getting hammered due to the cold weather. Morning commute this morning at 2 degrees 41mpg.
Last tank averaged at 41.4mpg which is bang on with the computer!
-
Visual inspection is probably just the beginning. It won't be hard to look up at the rear of the engine on a ramp.

My first GTD drive (10 mins after taking delivery)
South Wales to Manchester 54.9 mpg
Manchester to South Wales 60.1 mpg
Car in Normal mode
Driver in Running in mode (cruise set to 70 - 75)
-
My long term averages hovers around 48mpg. Today was nice and sunny with temps between 12/13 degrees. A trip from Edin to Glasgow got me a 58.9mpg which is record for me.
-
Mot testers have to visually inspect where the dpf should be. If it isn't on or looks like it's been tampered with then it's a straight fail. That's what I've been told by an mot test guy but I'm sure people will always take the risk.
-
It's so up and down with the temps at the moment, and my mpg is up and down like a yo-yo too:-
Yesterday morning commute to work (light traffic), -2C, 13 miles commute, 41.7mpg
Yesterday afternoon drive into Newcastle (moderate traffic), +14C, 8 miles, 45.7mpg
Yesterday night, drive home from Newcastle (very light traffic), +9C, 8 miles, 49.2mpg
This morning commute to work (light traffic), +3C, 13 miles commute, 41.9mpg
Last night's drive home was probably the least saintly, an Alfa Mito was hitching a lift (or so it seemed), until we passed the cameras on the Coast Road and it ate my dust as I left it far behind.
-

And for that saintly deed you were rewarded with the best mpg - could that be a lesson to us all... :smiley:

Having driven about 200 miles so far, and read all the contributions on this thread, I suspect that distance travelled and temperature are the biggest contributors to GTD mpg. My daily commute is about a 60 mile round trip, bit of town driving, mostly A roads and dual carriageways which seems to be helping push the average to decent levels.
I'm averaging about 53mpg so far which I'm more than happy with. My MK5 GTI returned around 31.5 mpg on the same roads. I find it incredible that such a superficially similar car performance wise can give such an economy increase. Although this may dip into the 40s once I've run it in properly :laugh:
-
Had a run back to Peterborough to do today. Driving quite regularly really, given I've a heavy right foot ordinarily.
(https://dl.dropboxusercontent.com/u/4147571/gtd/IMAG1825.jpg)
It seems about all she was willing to give today, driven like a saint at times, though I was experimenting with cruise also. I have literally just crossed the 600 mile marker.
My Peugeot would deliver 50 on this run driven like a hooligan.I do a lot of town miles these days so it probably did a regen straight off, but still, finding it difficult to sustain over 50 - you go for the throttle and it plummets.
Cant see much of an oil temperature pattern on mine, it wanders all over the place even on consant speed runs. Cross the 100 marker briefly on a few occasions.
-
Mine's now got 6200miles on the clock. Averaging 48 over the last 3000 miles. Last two weeks it's been above 54mpg on ASDA fuel all the time. Today did a 60 mile journey, mixed roads through town, on ECO setting and averaged 37mph and 61mpg on the MFD. Finishing the journey with the fans on full blast mid regen :laugh:
Mine will also do a regen at the end of a fast 200 mile journey, which doesn't make sense.
On the subject of stone chips, my paint is holding up well, but the windscreen looks like it's done 100k.....
-
I think sometimes we think it's mid regen and the fans are blaring but I think it's just the fans trying to cool the dpf.
-
I think sometimes we think it's mid regen and the fans are blaring but I think it's just the fans trying to cool the dpf.
I think that's exactly what it is. With the DPF now being strapped to the back of the engine and potentially being 600C internally, you probably can't just let that thing cool down on it's own.
If i've been on a long/sustained dual carriageway drive, I quite often come back to the fan blaring, even if it has been driven very economically (like sat at 75/80 for 30+ miles).
-
Impressed by others recent MPG figures but I did a gentle run Friday, it was thick fog so had no choice and got 49.6MPG over a 14 mile trip to Ipswich in Suffolk.
At last a decent figure! Strangely I switched the air con on last week and will now keep it on until winter returns, I wonder if that has helped the MPG (you would think it would make it worse)??
250 mile sprint to Devon coming up Monday - will report on how that turns out.
-
Things are just getting crazy now. 57.4mpg on 11 mile trip home from work!
-
My long term mpg has just topped 50 mpg...I'm happy with that one.
-
Had a regen most of the way home (stop/start wouldn't work, idling at 1000rpm) and still making an indicated 48mpg for the journey. That would've been a likely 41mpg a few weeks ago. The 12C ambient temp is making a big difference. That's my first proper forced regen in about 800 miles.
Seeing as my mpg hasn't dropped off at all in the last few days leading up to the regen (you usually start to see it deteriorate as the DPF fills and the back pressure increases), I think it might be the one the car initiates regardless of DPF loading every 800 miles just to ensure everything gets clean. Seems the box has improved my DPF operation, the car seems to run that little bit hotter than it used to.
Coming up to the end of my 2nd tank with the DTUK box on and this one is looking a little better than the first. Seems like i'm going to get about 20 miles further on this tank than the last.
-
I agree with the temperature variance, i've now been averaging 46.5 for the last 2500 miles, which is much better. I did manage 63mpg for a 35 miles, filled up at Bedford on the way home and then sat at around 60-65 for the rest of the journey. Not very exciting though.
I find the first stretch in the morning is crap. Once the car is warmed up I'll start to get around 47mpg once I get 50 plus miles done.
Will then get 50+mpg for journeys later in the day, particularly with the higher ambient temperatures.
-
2nd fill up with the DTUK box on:-
442.3 miles done, 46.13L/10.07 Gal = 43.9mpg actual, 47.1mpg indicated = 7.3% optimistic MFD (half of which I attribute to the DTUK box). 44mpg, but a lot of fun getting from A to B!
I'm going to stick the box on 3+1 after seeing Andrew's latest Dynos of 3+1 vs 4+1. Maybe it'll yield a little more power or use a little less fuel to do achieve the same end result.

Back with the 4+1, and giving the missus a lift to work up the A19 at 6:30am, the first mile is up a sustained moderately steep hill. A Kia ProCeed GT (201 bhp/265 Nm) decided to have a go and did fine in 2nd, but fell back in 3rd and 4th to 80mph and I easily passed it from 50mph and put plenty of distance between us to 80. When he did catch up, I put my foot down in 6th and went straight up to 100, and it took him the best part of 1/3 a mile to catch up. As I started to slow down to take my turn-off to Killingworth, he eventually got past with the engine absolutely screaming - must have been 4th gear acceleration outdone by my 6th gear acceleration.
So a bit of a mad 4 miles of a 16 mile round trip, although we were the only 2 cars on the road. I drove normally for the latter 8 miles and still returned an indicated 47.6mpg, with an ambient temp of 2C (no ice around). If i'd been moderately saintly both ways, I might've been pushing 49/50mpg. Doesn't seem much of a penalty for having some fun.
Amazed how quiet and composed the GTD was sat at 100 in 6th, doing 2750rpm.

She did, but even she commented about how quiet and smooth the car was. She doesn't know i've got the box though, she'd have wanted that £359 to go in the holiday fund! :grin: :evil: She must think that a stock GTD is awesome, and that a stock GTI is even more awesome. :whistle:
If you're at a loose end tomorrow morning, you could have a go with the box.

In-Laws are visiting tomorrow mate sadly. Fortunately my missus has came round to the idea of the box so when I've got the cash I'll be investing I think. Definitely be keen to have a trial run though - even if you just show me how it's fitted!

Matt, i must admit that the tone of your posts since fitting the CRD-T have changed so much :) Im glad youre enjoying the kit.

Aye I must admit that the box has brought out the boy racer in me at times, and greater enjoyment every time I use the car. I haven't enjoyed a car so much since I had use of my boss's Ford Granada Scorpio Cosworth for 2 weeks as a 19 year old when he went on holiday!
When the car has this much go, you forget about chasing the mpg so much (not that I am any worse off with the box on) and just learn to enjoy the extra performance with very little fuel penalty. GTD mpg and GTI exceeding performance - the best of both worlds.
The right box has made such a difference. Not only loads more power and torque, but usable torque and power, with a natural feeling of progressive delivery.
I've got to get my car booked in to the dealership for a door realignment (the rubbers between the front and back passenger doors slightly rub when the front door is opened) - going back to stock for a day or 2 is going to be hard!

Hi everyone
This question is off topic but I'm not sure if the VW (city gate) in High Wycombe are being dumb ***** as I have just got my GTD 8000 miles on the clock. But the steering is a little off centre to the right.
So when driving in a straight line I have to hold the steering wheel slightly to the right. Although slightly it's still noticeable. I explained this and the put it on the tracking machine but it's still not centre. They said its because the car is set up like a go kart and it's meant to be like that. I think this is tosh.
Can anyone confirm or deny this? Or if there steering wheel is completely perfect?
Your help would be great.
Forgot to mention I had the DTUK box from Andrew in my mk6 GTD and am going to get it changed for this one. Can't wait to have the extra grunt again.

Mine is dead straight, as is my dad's. If it's far enough out, they might have to have a mess around with the steering rack to get it straight.
If you get no satisfaction from your usual dealership for a clear warranty issue, try another.

Hi everyone
This question is off topic but I'm not sure if the VW (city gate) in High Wycombe are being dumb ***** as I have just got my GTD 8000 miles on the clock. But the steering is a little off centre to the right.
So when driving in a straight line I have to hold the steering wheel slightly to the right. Although slightly it's still noticeable. I explained this and the put it on the tracking machine but it's still not centre. They said its because the car is set up like a go kart and it's meant to be like that. I think this is tosh.
Can anyone confirm or deny this? Or if there steering wheel is completely perfect?
Your help would be great.
Forgot to mention I had the DTUK box from Andrew in my mk6 GTD and am going to get it changed for this one. Can't wait to have the extra grunt again.
Mine is dead straight, as is my dad's. If it's far enough out, they might have to have a mess around with the steering rack to get it straight.
If you get no satisfaction from your usual dealership for a clear warranty issue, try another.
Thanks monkeyhanger I have them looking at it next week so will mention it to them.

Thanks. Now I have a bit more ammunition to throw at them.

125 miles to Salisbury on Friday night yielded 44.4, with motorway pretty much all the way, did 80 the first half and 70 the second half. 5 degrees ambient.
Coming home just now was mainly 7 degrees, 46.9mpg having averaged 63mph doing 70 all the way, very poor imo. Coming north on the motorway it was constantly doing around 42 instantaneous and was actually lowering the average.
1100 on the clock now. Oil temp heading home never went lower than 98.

Wow, that is poor. I can do a 37 mile journey from North Shields to Hartlepool, 80mph all the way down dual carriageway and see an indicated 53mpg/actual 49mpg around 5C ambient. On a 125 mile journey doing 80mph all the way, i'd be expecting high 50s. Mind you, I see much better (an extra 3 or 4 mpg) mpg with Millers additive, and using either Esso ro BP - what fuel are you using? 98C oil temp indicates a well warmed DPF for optimum passive regen.
-
Supermarket stuff, Tesco. Used it in my Peugeot for 9 years almost exclusively,might try a tank of bp or shell but going on holiday anyway. My oil temps are routinely that high, rarely below 98 really, on both legs. That was largely on acc too.
Mrs had the heated seat on all the way there :shocked: which didn't help but still. Will see how it goes. Trouble is it does a lot of town miles, so the first leg of a long journey will instantaneously deliver a dpf regen. It did better than that before when I went to Peterborough. Wouldn't mind but that's driving it like a saint mostly, caned it once briefly on the way home.
We'll see, if this sh!t continues I can't see me bonding with it well, May as well have bought a 6 R if this continues. It's failing to better that which it replaced so far.
-
C2K: I'm not seeing any fuel penalty for getting a DTUK box and having a hell of a lot more fun with the car at the same time. My regens have stopped since I put the box on because the car seems more eager to have the oil a little warmer than stock. The regens really used to cane my mpg.
-
I've been following your posts tbh, and will invest when she is run in for the same reason. I'd rather enjoy it and get sh!t economy than drive like a saint and get it! As soon as someone can map the dpf out it might get hollowed out! ;p
Still, I want an evo so I better keep it...Lol

Had trouble with that dealership in the past myself.....full of sh!t and cost-cut like no other
-

How much of a difference do you think this makes to the fuel consumption?
-

Depends how hot they get. If his Mrs has grill lines on her arse cheeks from the car then quite a lot!
They probably use 250W (max) on each seat, and average output on a journey is probably around 50kW/68PS maintaining 70mph. 250W / 50kW = 0.5% of your car's ouput.
-
I've never noticed an appreciable difference in performance for any car I've driven when I have the heated rear window on... or the heated seat (when I had them)... or the headlights...
What you're saying is that it is likely to make 0.5% of a difference to the fuel consumption... about 0.25mpg, I reckon that's so small that you could not attribute the difference to having had the heated seats on...
I notice that there is a big difference in fuel consumption on the motorway if I put the engine into ECO mode, as opposed to NORMAL or SPORT, perhaps 5mpg between NORMAL and ECO, for example. If I don't make the switch to ECO, I struggle to see 50mpg on the motorway...
-
Interesting that, as most of the way there it was on Eco, and all the way back it was on comfort as Salisbury's roads were utter utter sh!te!
I don't think the heated seat made a significant difference tbh, but funny that a woman needs a seat warmer for 2.5 hours. I only use it to take the chill out the leather!
-
Sport seems to be my most frugal mode. Eco is not much worse (but a little worse, the lack of response just frustrates me, so I end up pushing the accelerator more to get the same effect), but my mpg takes a caning when it is in normal mode (10% down) - I really can't fathom why. A few others here say the same about normal mode, but by no means everyone.
I doubt you could see the differences seen with heated seats on or off and conclusively attribute it to the seats rather than a change in driving style/wind direction or ambient temp.
-
I've crossed the 10k barrier in the past few days and, although the temperatures will of helped, it seems to find it easier to break into the 50+MPG ranges now.
Just to add my 2cents into the mix regarding ECO mode; I found it was worse on MPG than the other mode. I've just got it stuck on Sport now for the sake of it. I've never had a proper go with Normal but I figure I bought a GTD to be sporty (well slightly) so it can stay in Sport.

KyleB:
It's definitely the temperatures, have a few cold days and see your mpg dive right back down. The last 4 mornings have been as cold as most of our Winter and as a result the car is 10% thirstier going to work (0-2C) than coming home (10-14C). I think i'll be hard pushed to do less than an actual 50mpg when the ambient temp is 20C+ on all but the shortest of journeys.
You care less about the mpg with a box on. I still keep an eye on what the car is doing, but if I have a bit of fun putting my foot down and the mpg drops, i'm not really bothered.

This morning though it was 1.5c and my car broke 54mpg easily. Couldn't believe it, DPF must of been squeeky clean (although haven't had a regen for a while). I can only imagine how much better the car is when you're not monitoring the MPG and just enjoying the box.
-
Im on 17k now and MPG has massively improved recently to be able to hit 50+ easily.
Had 64.7 last week on a 60 mile journey, the forever roadworks on the M6 helps :smiley:
Oil change soon...

That 303 really canes my mpg... Up and down hills like an up and down thing that goes up and down a lot! Totally agree about sport mode....or individual mode to be more exact... Also agree with the "just drive it" argument. I am generally nicely surprised when I don't chase the mpg.
-
Averaged 57.5 over Surrey to Manchester and back.
510 miles since last full up and have over a quarter of a tank left
that's excellent stuff. Wish mine would behave like that.
What miles you got on the clock now, what BW were you?
-

That's cracking going that.
I take it you're not using ACC and doing about 60-70mph?
-
Yep, no cruise used and sitting at 70 with the occasional overtake at 80. I also did some B roads, sat in roadworks for 40 minutes stop starting and before that I was at 58.4mpg
That's fantastic MPG mate - I thought mine was good at 54!
-
Finally seen the better side of 50mpg, drove home from Gloucestershire to Suffolk with car in Eco mode, gearbox in Drive and Radar cruise on and she managed 50.3mpg and doing 80mph most of the way home.
But then yesterday did a short 20 run to a local town and did get stuck in some traffic and it returned the lowest ever seen of 33.3mpg
I remain highly impressed with drive all round, 2700 miles on the clock now, 700 miles done this week and feel fresh and ache free when I parked up.
I am still slightly confused by the DPF regen - how can I tell when one is taking place?
-

I found my speedo to be about 3mph optimistic at 70, but even allowing for similar that's a decent result.
Avoiding the cruise control does seem to help. If I do use it I usually keep the cruise setting it in Eco, which some people find a bit too pedestrian on acceleration but I find it's okay if you're not in a hurry - and a bit more efficient I reckon.
-
Finally got my car on April 1st. Straight from the off mpg has been impressive. Daily commute is 140 mile round trip, about 80% motorway, remainder mix of A and B roads. Average over yesterday and today is approaching 52mpg, and I saw nearly 57mpg on way home tonight. Quite pleased with that. :smiley:

I think just as an important factor with the 57mpg result Pob got is that he does a 140 mile a day commute. If I did 70 miles on dual carriageway in one trip, doing 80mph all the way, i'd easily scrape 50mpg at 0-2C, and be pushing high 50s at around 8-10C. I regularly do a 75 mile round trip to see relatives, and was getting around 49mpg in freezing temps, and around 53mpg at an ambient temp of 8C.

Yep, I think it's the commute which is the reason. Last couple of days has been about 8 degrees in Lancashire dropping to about 4 degrees in Yorkshire. That was between 75 and 80 most of the way with some stop / start on the motorway. The non motorway bits are hilly so economy tends to dip then as you'd expect.

I managed to get 51.7mpg today on a 180 mile trip down south to visit family. That was sat at 80ish all the way. MPG was woeful until it warmed up though after about 70miles it really started to improve and then hung around high 40s to early 50s

That seems a bit low considering the length of the journey, if that's indicated rather than actual. I took the missus to work at 6:30 this morning, 16 mile round trip back home, 6C ambient temp, 80mph most of the way, indicated 52mpg, which will most likely be an actual 47mpg (considering the DTUK box takes the indicated/actual discrepancy from about 3% to 9%). If it's better than you're used to then I suppose it's a bonus.

That was indicated mate. My MPG seems very random. To work it will vary wildly from 49-57 and I can't even explain it. Can even get high 50s when the temp is low.
-
With a healthy 18C ambient temp today, I did a round trip of 29 miles to the Metrocentre, not sparing the horses on the A1, and did 52mpg indicated, which is a probable actual 47mpg given that the DTUK box makes the MFD overestimate by approx 9%. If i'd have taken it easy, i'm sure i'd have seen 55mpg indicated (50/51 actual). A TR GTD 5DR pulled up beside me on the A1 gave me a wave and went to speed off hard. Dropped to 4th and left him behind by quite a margin which demonstrated the difference the box has made. Then the missus was moaning about my speed. :whistle:
-
16.5°degrees today in Sunderland and couldn't crack much over 40mpg. Only about 8 miles but still not good.
-
Quite happy with this today. 142 miles from Bicester in Oxfordshire to Cheshire on what was quite a busy and slow going at times journey. Had ACC set on the whole journey at 75mph, but a lot of the journey was sub 70 due to conjestion (and sometimes below 50mph). Ambient temps about 14 deg C.
Also, don't forget, mine is a DSG which is worse on fuel.

-
A very decent result. I would doubt DSG has any penalty on a long run, unless its downshifting for harder acceleration with ACC on a more spirited setting. I've touched 60 mpg on long motorway runs a couple of times which also included a fair number of roadworks sections (or just mile after mile of cones...) restricted to 50.
-
What settings have you got on individual mode Andrew? Did you have the climate on during your journey? Chris
-
Chris,
My "individual settings" are:
DCC: Comfort
Steering: Normal
Engine: Normal
ACC: Sport
Dynamic Bend Lighting: Sport
Air Conditioning: Normal
Yes climate was on for the whole journey @ approx 22°C (AC on). On the trip down to Bicester, is was less busy and so I managed to cruise pretty much at 75mph the whole way (no hold ups at all), and still got 56.7mpg.
For info, the car currently has 5,600 miles on it.
-
Had a good 100 mile round trip yesterday, returned 57.5mpg from setting off and parking up back home. Had climate control on (no AC), car set to Normal, ACC set at 80 on the journey there (with quite a bit of variation of speed due to cars coming in front) and no ACC on the return journey.
Only got approx. 300 miles on it yet, but I am extremely happy with that.
Also, on the way to work which is 18 miles from my home, I returned exactly 50 mpg from setting off to parking up. Although traffic was quite bad, it is 90% motorway. Can't complain at all.
-
100 mile round trip to Aberdeen on Saturday morning. Only achieved 49mpg, pretty poor considering it was 95% dual carriage way sitting at 70mph-80mph. On the way home I set the ACC to 75mpg and the mpg just dropped, so turned that off pretty quick.
Checked my tyre pressure this morning, they were all sitting at 26psi... Topped up to 32psi, so hopefully things should improve.
-
I'm still no where near 50 even on a run! Got it booked in for a puncture repair tomorrow and an ecu update apparently.
-
I did a solid 150 miles today on a mix of A roads and B roads and motorway. Ambient temps approx 12 degrees. Got relatively poor 48 mpg!
mcmaddy - would they say what the ecu update is for? Is this something that would be done as standard on a service or something you would need to specifically request?
-
ECU update was for abs system apparently. It'll be done when your car is next in as a matter of course although the lady on the phone when I booked in kept saying it was a recall and then quickly changed her mind to a factory update.
-
Checked my tyre pressure this morning, they were all sitting at 26psi... Topped up to 32psi, so hopefully things should improve.
The min tyre pressure listed on the fuel flap for my GTD is 36psi (light load, set with cold tyres of course). I run mine slightly above that.

Might have to knock that up a little then!
-
I had a saintly 8 mile drive home today at 12.5C and achieved an indicated 58.5mpg, probably an actual 53mpg considering the 9% optimistic MFD reading I have with the DTUK box.
-
First full tank now nearly empty. First half of the tank was pretty much all motorway, second half mostly local short-ish journeys with a bit of putting foot down mixed in. Average for tank 50.2 which I'm happy with.
-
Like most cars the way you drive has a big effect on mpg. I got 56 mpg on a trip from Sussex to Cambridgeshire at the weekend and then 44 mpg on the way back. Needless to say I was keener to get home.
-
Trip to Pickering over the weekend and got 52mpg on Friday going down which was A19 and then Sutton bank route through Helmsley. On the way home today got 44mpg coming back the Whitby road over the Yorkshire moors. Can't seem to get a consistent mpg on any trip no matter what settings I use on the driver profile or what style of diving I use. Very frustrating!!
-
Maybe you were keen to get home, or the wind had got up?
I took a little trip out last night and was in a strong headwind to my destination, which became a strong tailwind on the way back. A normal 45mpg short trip became a 36mpg trip down, and righted itself to 43mpg back.
-
It was very windy coming back but with the amount of traffic and my yet again knackered back I was sticking to 50-60. I may as well have bought a gti at this rate or stuck with the 4wd tiguan that gave mid 40s all the time even with ruined tyres on.
-

I must admit that my mpg without Millers is sh!te, worse than the Scirocco. Forget fuel economy and get a DTUK box to have more fun with the car. My actual mpg is the same with and without it, and I have a lot more fun with it on. I'm happy to get a solid 44mpg (actual) around the doors when I have 240PS at my disposal.
-
So your actual mpgs haven't suffered at all with the box? I know the indicated on the mfd will be slightly out but it's good news if your actual is virtually the same.
-
Ive gone from an indicated 46mpg/actual 44mpg without the box to an indicated 48/actual 43 or 44mpg and active regens are a once in 800 mile event now (I think the ECU forces one every 800 miles, whether it thinks you need one or not). In fact when I took the box off for warranty work, my mpg suffered a bit because I was pushing the car harder to get the same result.
-
Yeah talking of regens mine decided to go into full regen mode a half mile from home after the journey at the weekend!!!
-

Sure it wasn't just the DPF getting cooled once you're almost home and going a little slower (therefore the radiator is less efficient when the car is hot)?
-
No this was definitely a full regen.
-
Drive from birmingham m6 j6 to East London via a very busy m6 m1 m25 and then the a406 up to walthamstow totalling 135 ish miles my mpg was reading 59-60.9 mpg mixture of 60-80mph. Best I've had since I purchased. But it was a full tank Brimmed. I will see what I get on the way back.
Back in Brum managed 56.6 in Eco mode both mway runs were.
-
I had my car in the dealers today to get an issue looked at. Got a loan of 2014 Tdi bluemotion golf. It's about 7 miles to the dealers. On going to pick my car back up the Loan car effortlessly did a whopping 64mpg. My GTD on the drive back home just about managed 49.9mpg!
I wouldn't swap my GTD for anything but I think the official MPG figures have raised expectations too much.
-
Pleased to say my economy has improved with mileage.
I've now covered 10,500 miles since an early January delivery and am now seeing a regular 60mpg on the motorway at 70mph dropping to mid/high 50's on A roads.
This is in Eco mode and changing gears when the car advises on the mfd.
When I completely ring it's neck mpg can drop to early 30's so quite variable, id say my old Mk5 GT 170 would get near enough 500miles to a tank give or take a few miles no matter how hard or easy I drove it.
-
I did Heathrow and back on Saturday, 200 miles prettymuch on the dot in Eco mode, almost all on ACC. On the way there, it was usually around the 48 mpg mark in instantaneous, as if it was a constant hillclimb. Achieved 48.2 on the way there with some low speed action at the end to be fair as I was very early.
Coming back, having booted it at least 4 or 5 times to join/change speed during lane changes, it was sitting at 50.2 when I got home despite arriving home with a forced regen at 1600 miles (as per other peoples findings, computer seems to force a regen at 800 mile intervals). Most significantly though, the instantaneous figures under the same conditions were a good 10mpg different coming back, without much change in ambient temp. It climbed steadily all the way home despite the aforementioned hoofing of it.
It delivers 45MPG round town with ease, but struggles to build much on that on the motorway as in my case lots of town miles usually bring a requirement for a soot burn as soon as a whiff of a long journey comes about.
-
Boll*cks to the MPG, that Night blue GTD of yours with the Santiago's looks the nuts :drool: :drool:
-
Haha thank you very much! I love her regardless of the mpg! :D
-
Easily hitting 52-54 MPG recently regardless of temperature. Had a short run out, which was about 8 miles round trip though and didn't get over 41. Think this car really struggles with short distances.
-
KyleB: Nail on the head - on my daily work run of approx. 40 mile round trip, 52mpg to even 60mpg is achievable. However, on short journeys I have even seen a poxy 30mpg average. Totally understandable but still correct that this car is not meant for short town journeys.
-
Mpg depends on a combination of driving style, journey length and temp. Assuming the driver is a constant, with my driving style in my GTD (80mph on the dual carriageway/motorway):
Doing a 5 mile journey at 0/10/20C ambient temp, I’d expect 35/40/43mpg.
Doing a 10 mile journey at 0/10/20C ambient temp, I’d expect 42/47/50mpg.
Doing a 15 mile journey at 0/10/20C ambient temp, I’d expect 48/52/54mpg.
Doing a 50 mile journey at 0/10/20C ambient temp, I’d expect 51/54/55mpg.
Doing a 150+ mile journey at 0/10/20C ambient temp, I’d expect 52/56/58mpg.
All those mpg figs are indicated (MFD).
0C ambient temp is a mpg killer – very hard to get much over 50mpg no matter the journey length, difference is less pronounced between 10 and 20C than it is at 0 and 10C, the temp gains pretty much level out at 25C.
Doing less than 8 miles in winter and 6 miles in the summer is a mpg killer – until the car is fully up to temp, it’s going to be very inefficient. The influence of the first part of your journey on the whole journey’s mpg diminishes with distance. If your preference is to sit at 70mph rather than 80, you can add 10% to the above mpgs.
That’s pretty much the way it is with real life fuel consumption, wondering why you only get 40mpg and someone else is getting 55, chances are that you hoof it a bit and have a very short commute, and they do 50 miles to work each day, sticking to the speed limits because half of their 50 mile journey is plagued with average speed cameras.

Almost 4 months in , 6,900 miles. Mainly shorter distance, clear road runs, some long journeys inc. m'way. Long term average showing 44.9 mpg. Bizarre thing is (vs 2 other cars I've got) is huge inconsistency on same routes/similar conditions. It can vary between 39 and 50... Never see that on other cars, current or past!
Like last post, weather has negative effect, DPF burn off also seems to have a negative impact.
Doesn't affect me personally, but feel sorry for those that may be choosing cars partly based on manufacturers claims. I know some senior car industry wonks and have learnt about what companies do to arrive at the figures... Should be rectified. Run some BM 3's on a company fleet and they easily do 60+ fairly regularly.
-
60 mile round trip today in the GTD. Drove there, 30 miles, in Eco, always inside the speed limit. Was a bit shocked to find the mpg at only 45, must have doing a regen but would that have such a effect over that distance?
Drove home in normal mode, bit faster in places with some decent acceleration moments and averaged 54 on that trip which was more like what I expected.
Only 1400 miles on the car by the way.
-
Just over 5000 miles on the clock and managed to get 62mpg on the way home from north Yorkshire using acc set at 65mph with occasional increases to 70 for safer overtaking.
-
I've given up chasing mpg to save £3 on a tank of fuel.
Today, on a trip down to Hartlepool (37 miles each way) I got 57mpg indicated (probably 52.5mpg actual) going down and 59mpg (54.5 actual) back. On a 100 mile trip (we were thinking about going down to York today, but didn't), i'd have probably cracked 56/57mpg actual. On that basis, sitting at 65mph would probably have netted me about 60mpg actual (equivalent of 62mpg indicated on a stock car). Pretty much the same as the Scirocco The 17C ambient temp helps.

I have found the real time mpg data screen a revelation. I had disabled this from the mfd settings but recently re-enabled. Really surprised how light a touch you need on the accelerator. I can easily get into the 50's now when using this screen. The drive itself is really boring though!

200 miles in and my car is averaging 41.9mpg and hasn't been near a motorway. Average speed so far is 19mph :embarrassed:
Will be tackling a 120 mile motorway trip at the weekend so very interested to see what it can achieve there.
-
Managed to crack 70 mpg average for a while today. Settled at early 60's toward end of the journey (around 12 miles). Normal mode 17 degrees. Took a pic lol.

And car has done around 850 miles! I'm happy!

47.8mpg driving "normally" (70-75mph) to work this morning, 61.7mpg driving like a nun (ACC set at 60mph) returning home this afternoon.
2-3 miles of 30-40mph local roads and through town, 22 miles of dual carriageway and motorway.
45-48mpg is typical, getting the higher numbers to show on the computer is possible but involves driving in an unrealistic manner (felt like I was on the Top Gear episode where they had to drive from Switzerland to Blackpool on a single tank of juice).
-
Crazyhorse: Are those indicated mpgs or brim determination actuals? You'll find the MK7's MFD to be pretty accurate (around 3% optimistic), compared to previous generations and most other cars i've been in that haven't had a new model in the last year or so (8-10% optimistic).
For your 25 mile commute, those figures are pretty poor. I don't spare the horses and regularly hit 45mpg actual (50mpg indicated) on my 12 mile commute to work with a dual channel tuning box (which bumps up the MFD discrepancy to 9%), with 2/3 of that maintaining 80mph on dual carriageway.
I find it very hard to do less than 43mpg no matter how hard I drive the car. On a longer journey (40 miles) with the same driving style, I can get a 50mpg actual (55mpg indicated) in the current weather with 8-15C ambient temp.
I've gotten over the initial mpg disappointment and am happy with a 45mpg commute and 243ps on tap with the box.
-
Thanks. Those are indicated numbers as shown on the mfd.
Yeah my indicated numbers are typically 45-48. Starting to think I have a hole in my fuel tank based on your numbers. Is fine, just thought it would be better that's all.
-
This afternoon on the way back down the M1 from Leeds I nearly hit 64mpg :laugh: there is a lot of 50mph road works and it was busy, most of the way at a leisurely 65-70mph cruise and have done 2700 miles since 14th April and getting better every tank...

In case anyone is as interested as i am!? Here is a screen shot, literally, of my fuel log to track performance, starting to build a picture through loosening up that tight engine (http://i1184.photobucket.com/albums/z334/davethecat2/20140513_22284_edit_1400182437355.jpg)

That's a neat record Dave. Wish I could get diesel for 123.9p :sad: I know that perpetual 50 stretch of the M1 only too well - frustrating, but great for us fuel misers :grin:
-
Demonstrated pretty well today that temp has a huge effect on mpg. Picked the missus up from work, went to the Metrocentre, then her mams and then home, 37 mile round trip, was caning the car up 2 long sliproads (one onto the A1, one onto the A19), each pretty steep and about 3/4 of a mile long each and maintaining 80-85 on the dual carriageway sections, with the aircon on all the way. Result was an indicated 55mpg for the trip on what has been the hottest day of the year so far (21C). A few weeks ago, doing the same on a miserable 12C day with no aircon would have just brushed 50mpg. That's not down to running in. Up to about 7700 miles.
-

Thanks, yes probably the only up side of average speed zones...the £123.9 per litre was due to the Tesco clubcard kickback they had going a few weeks ago, I get all my fuel from Tesco as saving up the points for another trip to Lego land, and may even take the kids!!!
-
Yeah - I agree regarding cruise but I regularly do a stretch of road that I can sit at 70mph on and not have to slow down for much. Hopefully the adaptive part of the cruise can be turned off and just used at constant speed.
If I can get 50mpg on the motorway out the GTD I'd be satisfied, 60mpg I'd be over the moon - anything less than that I'll be pretty annoyed..
Will be interesting to see.
I got 50mpg on a GTD DSG (extended test drive of demo) doing a 62 mile round trip with about 12 miles around the doors and 50 miles of it sitting at 80mph on dual carriageway. The car had less than 900 miles on the clock (so some running in gains yet to be realised) and the DSG will hit you for 10% on your mpg vs manual so expect at least 55mpg with the manual. I had ADC switched off and no aircon on that trip, ambient temp about 20C. About 8 times on the trip cars overtaking lorries slowed progress down to 60mph, but as soon as they were out of the way I buried the accelerator until I hit 80mph again and stayed there. I think it will meet your expectations. I didn't have cruise on - not sure how much fuel penalty you will incur for that - maybe a fair bit if you try to drive closer to the car in front than ADC would like and it is braking for you regularly.
I keep an eye on the 'instant' MPG display when the ACC is slowing me down and it actually jumps (increasing MPG) considerably I've found. Could be that regeneration is factored into the parameters to cause this?!
-
I'm on 1,500 miles now - long term mpg is reading 49.9. Hoping to break 50 mark with warmer weather!
-
4 months and just had my first decent run out, 180miles and mix of motorway A and B roads averaged 51mpg which is not bad, car is loosening up and has just turned 2800 miles, 42 the trip is showing from new, oh and I do use my right foot..
-
My long term is 39.8 after 4000 miles but I do a lot of short journeys which probably don't benefit, I did get the GTD over the GTI thinking it would have a bigger tank and therefore less petrol station stops, I was wrong.
-

????
That information was available pre-purchase... you didn't have to use guess work.
It would be quite unusual for the size of the fuel tank to differ between models unless there was a very good reason (e.g. the 4WD version of the 996 Carrera has a different design and size of fuel tank to the 2WD because the 4WD gubbins get in the way)...
-
yep, like I said, I was wrong
-

Regardless of the fuel tank size, lots of short journeys in a GTI will see it doing MPG in the 20s, so I wouldn't say you made a massive mistake.
-
So largely mine has been doing well as of late. 140 miles to Wigan followed by wedding duties in Liverpool City centre saw 53 for the 300 miles of the weekend with ambient around 15, oddly it regenned as soon as I got to Wigan, but it must have been spotless as it had just done one last use. Long journeys seem to incite one.
I went to the peak District on Friday in rush hour m1, 20 odd ambient. 75 miles with lots of stop start traffic did 54 mpg, return leg with no traffic but lots of slow driving/passing cyclists/sightseeing saw 55.5, best yet, and it was in the twenties at one point such were the nuisance cyclists. Just passed 2500 miles here. That was large amounts of acc too.
Car went back to Peterborough vw today to sort out some delivery damage, which resulted in 54mpg at 18 ambient, and I played with a mk6 gtd mid way. I'm easily attaining 500 miles to a tank if I use motorways, and have managed over 50 litres on fill up with 35 indicated to go. Depressingly though, courtesy car is a 150 blue motion that had 6 miles on the clock, did a pretty effortless 60 coming home with a dpf regen at the end! Started at operating temp though but still..
-
So my first tank full has turned up a 45.7mpg average without even trying. This included a long trip down to Wembley and back from Derby (c.240 miles) and commuting to and from work (20 mile round trip). Have to say I'm happy with that, I have been trying to vary the revs as the engine is new, also I know it has done at least one regen.
-
This included a long trip down to Wembley and back from Derby
I bet that was a long trip home :cry:

Had some of my best MPG yesterday. Went for a day hiking in Snowdonia and on the way home, left Ogwen Cottage on the A5, and checked my MPG just after Betws y Coed (a total of 14 miles) and was astounded at what I saw. Now I know it's pretty flat from those two points with a few downwards gradients and it was.............wait for it ...........96.8 mpg :shocked: Blinking heck, nearly 100 mpg, and that's after 14 miles (not just a quick 1 mile run).
Anyway, did the rest of the journey home, and followed the Navigation which took me over the tops on a fabulous 18 mile twisting mountain road across the fells. Full of steep upwards paths, hairpins (just right for gunning out of), and long undulating straights (I'll have to get the map out and see the name of the road).
Anyway, checked the MPG again when I got home (over 80 miles and 2 hours later), and despite some horrendous hold ups, I got this:

Got to be pleased with that especially as mine is a DSG :grin: Car was in normal mode for the whole journey, with the gearbox in "Drive" (not sport), and ACC off. It keeps getting better and better !

Firstly sounds an amazing drive out. Think people forget what a beautiful country we live in as get complacent and simply do not go out and experience it.
Recent trips to Manchester have gone up to my personal best of 57 MPG (180 miles each way)
Think would struggle to break that now for this particular journey but good to see someone genuinely break 60 MPG
Both my Audi improved over time so was not panicking at early reports of not great MPG returns.

Epic pics and mpg chap. :)

Cracking pics sootchucker, if you had managed to hide your GTD in the distance in one of them you could have been a contender for best GTD pic. :)
I've done just over 1400 miles in mine now, the long term is looking pretty good (it was reset after the first 60 or so miles):
(http://i.imgur.com/gvxAH6L.jpg)
Had my longest trip last week, 200+ miles on the M4 and into central london for, ahem, Katy Perry :laugh: Traffic was terrible in London (took over 2 hours for about 15 miles) but still did a 54mpg for the trip.
Was my first go with the ACC too, very cool indeed, I was certainly covering the brake with my foot the first time we went from a 70 into a 50 zone though! One funny thing with ACC, it's nice following someone in a 50 motorway zone, but I was forgetting the car still wanted to go 70+, so as soon as someone pulls over... vroom, opps :)
Need to read in the manual, but I couldn't see a way to 'resume' ACC, I got only turn it off and then set it again with a new speed.
-
Well after first tank managed 33mpg with 200 miles around town very short trips and 130 motorway miles. Hope it will get better with time.

Drove from Sunderland to Arran yesterday and managed to get 57mpg. Would have been way more but the overtaking at Greenhead bank killed the mpg and it took a good while for it to recover. Plus the last 20 miles was foot down all the way as time was catching up with us for the ferry crossing. (Can't remember how to add pics into posts either)
-

Ah, as easy as that? Not sure what I did as I ended up thinking RES stood for reset, will try again - thanks!

Res = Resume in cruise control speak.

Seeing a good improvement now car is up to 7k, previously averaging mid 40s I'm now getting 52-55mpg and not hanging around either. Sticking to BP ultimate

Is there much of a difference between the premium brands of diesel as opposed to ASDA, Tesco etc?
-
If there is a benefit, I believe that it is small much smaller than the benefit you see with premium petrol in a car tuned for 98-RON.
For me I've seen no measurable benefit from using premium fuels so I just stick with ordinary Shell.
Today averaged 59mpg according to trip computer on a return trip to Manchester, adaptive cruise set at 75 on the M6...
-
Been using esso diesel with a shot of millers each fill up. Used shell normal diesel before that but I always stay away from Morrison's and asda as my previous tiguan ran like s4it on it.
-
I'm planning on only using standard Esso when possible. I've always used tesco etc in the past, but wanted to be kinder to the GTD. Plus you get tesco points at Esso now, and it's actually slightly cheaper for me locally!
From the limited research I did (and it's amazing how little info there is out there), the diesel's are from the same source at the depot but Esso/Shell etc, do add additives that are not added to the supermarket lorries.
Anyone know for sure?
-
I'm getting the same as some of the posters running on "premium" fuel and I'm running on Asda/Morrisons or Tescos whichever is the cheapest. Think the ambient temperature is more to do with the ease of getting 55+ all the time now.
-
Tootled around Arran yesterday and got 58mpg. Was trying my best to crack 60 but the steep uphill climbs in some parts were killing the attempt :grin: Ferry to Mull today so will see what happens.

For those achieving high 50s, are you driving really conservatively or just driving "normal" without gunning it?

-
For those achieving high 50s, are you driving really conservatively or just driving "normal" without gunning it?
I'd say a bit of both. I normally cruise at 75-80mph. I like to use the full length of the gears (read: boot it) when joining roads/carriageways. Certainly not nursing it.
-
For those achieving high 50s, are you driving really conservatively or just driving "normal" without gunning it?
For me to achieve high 50s - It's normally motorway acc set at 75mph.
High 40s low 50s are achieved hacking around rural Warwickshire and elsewhere. Most who know me would say that I don't hang around - not much passes me - but I don't drive a like a lunatic on public roads...
-
58mpg from Arran to tobermory. Not gunning it but not driving miss daisy either. Also managed to gently scuff under the front bumper diving off a ferry from Lochranza :angry:

The average MPH indicates a lot of town driving or commuting which will keep the MPG lower and around late 30s to early 40s.
The 55MPG + figures being demonstrated on here will all have involved some stretches of cruising on Motorways or A roads with most photos displaying MPH in late 30s to 40s and beyond. (Sootchucker 62mpg was at an average 39 mph)
Things to remember is that out of the box MPG is average but most on here who have had performance diesels all say same that MPG increases markedly as miles are placed on car and engine settles in.
I would say yours is not too far off being right for that MPH and that if went on an extended 100 mile trip on some decent A roads or motorway it would readily jump into mid 50s and beyond.
-
A friend with a 63reg Audi A6 2.0TDI (177PS engine) was commenting the other day on noticeably improved response and mpg since passing 6000ish miles. Will be interested to see whether mine does something similar when I eventually get past that point, as it doesn't seem to be a common finding with other GTD drivers so far.
-
I'm on 8200 miles on mine and my dad is on around 18k miles with his - the cars aren't noticeably looser than they were after 1000 miles. Power and economy gains we've seen recently are down to the warmer weather, we had that one cold week after we'd got used to the warmer temps and the mpg dipped right back down. Some people will hail their recently improved mpg as running in gains rather than seasonal gains, but will see that dip again in the winter. 52mpg on my 13 mile commute to work and I was really putting my foot down once the car had warmed up. Oil temp seems to get to 60C very quickly right now, but 60-90 takes a very long time, like that heat is being passed on to the DPF as soon as it is generated.
If I were to religiously stick to 70 on a 100+ mile motorway run i'd be confident of cracking 60mpg quite easily. The best I did in my 170TDI Scirocco was getting a recorded 59mpg for a maintained 80mph 350 mile journey with the aircon on all the way.
I've never seen the noticeable long term running-in gains that some report to have seen, with 6 new TDIs before this one. I have always seen a noticeable seasonal change though (summer mpg/output 10-15% higher than winter). I haven't seen any noticeable real-world improvements with the GTD on the economy front, it's all in how the stop-start affects the test outcomes.
With the DTUK box i've definitely cared less about chasing an extra 15 miles to the tank and loving the extra power. My next car may well be an S3, and to hell with the mpg - i'll be averaging 28 in one of those if i'm lucky.

Yeah absolutely, it's exactly what I expected and I'm not unhappy with it. I got up to around 50mpg on a 120 mile motorway trip, but at that point the car had less than 200 miles on it and it was pretty cold.
-
A trip I make across Edinburgh at least twice a week is 7.8 miles in length and I have to pass through 13 sets of lights, mid-morning so the rush hour is over. I regularly achieve sub 50s MPG and on a few occasions when I got the breaks with traffic lights, I got 53/54 MPG. Only one small section of road is a 40 limit and I'm in ECO mode except for Climate, with Stop/Start active. Long Term is currently 52.5 MPG, so City driving is not having such a big hit on economy as I at first thought it would.
My first ever TDI was a '98 Passat 110 and this performance and economy from the GTD is something astonishing in comparison. Also the lower insurance over my previous Scirocco 140 TDI.

Well at 8400 miles on the clock, my "1000 miles to service" message has just appeared in the dash. Won't be long before I find out for myself whether the first oil change brings any noticeable improvements in mpg or whether there are a few warranty ECU tweaks to be performed while it's in.

Were the servicing intervals shortened due to the 184 engine needing more regular inspection or is it to generate more revenue for dealers? Call me cynical!
-
Asking for a service at 9400 miles is about the norm for a 10k interval service these days as it is 15,000km and the car is running in km (in the background) and converting everything to miles for our convenience in the UK. They’re usually happy for you to hang on until up to 11k miles without affecting your warranty, but with 3 services paid up in the pack and no way I will be keeping this to the point of the car asking for a 4th service, I don’t see the harm in doing it as soon as it wants it rather than holding out for 10/10.5k miles.

I'd put it down to MH's commute (I think it's fairly short). I got to 10,000 miles without a service reminder coming on. I only booked it in because it was on a service plan.

Well at 8400 miles on the clock, my "1000 miles to service" message has just appeared in the dash. Won't be long before I find out for myself whether the first oil change brings any noticeable improvements in mpg or whether there are a few warranty ECU tweaks to be performed while it's in.
Were the servicing intervals shortened due to the 184 engine needing more regular inspection or is it to generate more revenue for dealers? Call me cynical!

I thought that only happened when you go variable/longlife. My commute is 13 miles long - not drastically short. I'm on a fixed plan, my last Scirocco asked for 1st service at the same time (9400 miles). The Scirocco before that was on long life and asked for one at 18k miles. I've been in the same job 12 years and my commute hasn't changed in the time of ownership of the 3 cars.
-
Should be getting the reminder at 9k if you're on a yearly or 10k service schedule. Anything else and the service reminder has been incorrectly set.
-
9400 miles is a common time for VAG cars to want a 10,000 mile service (with 1000 miles grace), purely because it is 15,000km, the service interval on the continent. If you google "9400 mile service" you'll see all sorts of VAG owners saying theirs is due then, be it Audi, Seat or Skoda. At 600 miles earlier than expectation for it to be officially due, i'll not sweat it. If there is a fine tune to set exactly 10,000 miles rather than the mile equivalent of 15,000km at PDI then it hasn't been done on mine for the past few cars at least. My dad had the same on his, so I would guess mcmaddy is due the same, being from the same dealership.
-
I bought the 3 year service plan a few weeks following delivery. At the time I remember looking at the unique vehicle codes and deducing that the car had definitely been configured for the default variable servicing in the factory (i.e. using the "long life" map for predicting service intervals). So if some other people on fixed servicing intervals are set up the same way that might explain differences in servicing messages approaching 10000 miles.
-
I've never seen the noticeable long term running-in gains that some report to have seen, with 6 new TDIs before this one.
I must say that's been my own experience too with the two previous ones I had.
Assuming there must be some tolerences in production that affect how relatively tight one engine end ups compared with another when they leave the factory, then that could go some way to explain variations in how much loosening up and apparent running-in gains are experienced by the first owners.
-
All cars are set to long life from the factory. To be honest even if the car is on time/distance or variable servicing you can get your serviced whenever you like. They use the same oil in diesels for both servicing regimes so it's just a case of the supplying dealer being capable of doing a proper pdi and changing the service indicator. As people are finding out most dealers are useless at this :whistle:
-
It's in the dealership's interest to get you on fixed interval servicing by taking you off the factory set long life regime - they want to get frequent servicing revenues from you. If you've bought (or been given) the service pack you will certainly be on the time/distance regime because the service pack doesn't cover the cost of long life services. With my car being due on 9400 miles (nearest rounded up imperial equivalent milestone to 15,000km - the continental service standard for distance), it is certainly on time/distance as i'd be expecting a long life service to be kicking in around 17-18k miles based on the last time I had a car set to long life.

With modern manufacturing tolerences being so so tight these days, i'd imagine that the vast majority of your "loosening up" happens in the first 1000 miles and even then there's not much of that. The old legend of VW engines not being run in until they've done 30k miles is long gone. If the engines had significant running in to do these days, we'd still have a first oil change at 1000 miles to get rid of all the metal generated from running in like we did 20 years ago. For those who bought their car last year and are now seeing those "running in" (summer) gains, let us know what mpg you're getting in 6 months time and see how it compares with last Nov/Dec's figures.
-
Apologies MH, thought you had a short commute. My car is indeed set up for the variable servicing but I'm not arsed, I'll chuck it in every 10k as per the service plan then I'll get it serviced yearly by my friends dad who I know will do a better job (if I even keep the car that long)
-
Kyle yours shouldn't be on variable servicing if you have the service plan. It should have been changed at pdi.

I'll raise that with them next time I pop in. Not a massive worry though as I know when it needs a service.

Yeah agreed mate. Just stops the annoying service bong. Where did you get your gtd from?

Picked the car up yesterday from Kent and drove to Warrington, then drove the rest of the journey today back to Glasgow. Just over 500 miles so far on the one tank with the display showing 56mpg.
Not bad for its maiden journey although I was driving reasonably slow to avoid the stone chips on the way up the road :rolleyes:
-
Is this some kind of record for a GTD
(http://i1184.photobucket.com/albums/z334/davethecat2/Mobile%20Uploads/20140619_150009_1.jpg)
PS: I was Driving with a space saver on
-
That's ridiculous!!!!!!!!!!! The best I have had from the car is 58mpg. I literally cant sit on the motorway at 70mph, get waaaaaay to bored the wheel. Impressive bordering 72mpg
-
I've found coasting whilst in ECO mode with everything switched off and using anticipation instead of ACC, can have dramatic results in MPG figures but you'll be late, all the time.
-
Cheers, so how did i do it......I will start by saying my long term average is 47.9 after 4500miles, screen shot below from my Android milage app
(http://i1184.photobucket.com/albums/z334/davethecat2/Screenshot_2014-06-19-18-57-04.png)
The 71.7mpg today was done in Normal with AC on light, outside it was 19-20 degrees, I'm running on Tesco fuel and started from Basingstoke up the M3 to just passed Staines on the M25 where i hit traffic. I was driving with the ACC set at 52mph (50mph on satnav).
Now i have a full sized wheel back (bye bye space saver, hope i never see you again) normal service will resume, this sort of MPG is achievable on the right roads, if you have the time and patience etc...
-
Achieved 566 miles on current tank when re-fuel warning light came on. Mainly motorway miles in warm weather. I believe 600 miles is achievable!

Why did we buy a GTD if we are overly concerned with mpg? I get 46 mpg no matter how i drive the car. I thought that i was going to get almost GTI like performance with better mpg and that's what i feel i have. Now that my rear suspension and wiper issues are sorted out i'm happy. I'm wondering now why do people buy a GTD? Is it down to purely economy reasons or driving experience? I would like to hear your views.

Before I ordered my GTD, I priced up a 150PS TDI GT Bluemotion to the same spec as a GTD and it was only around £300 less, xenons and LEDs being the main pricy options.
Even with the pump price of diesel, I still think it's a win-win. I agree it's very difficult to return less than 45 ish MPG, even when 'sending it on'.
My preference for TDI is that rush of power you get from fairly low revs, the long range/economy and strong residuals...not forgetting the much lower insurance premiums.

For me it has been about the running costs vs performance when comparing a GTI to a GTD. With the only differences being under the bonnet, and small ones at that (discounting better initial traction on the GTI helping 0-62 times greatly), having nigh-on the same car for £110 a month less (between fuel savings and residuals) did it for me. I do like the way the high output TDIs develop their power as i'm more of an overtaker than a traffic light dueller, but hardly notice the supposed extra 30Nm and 14PS vs my old Scirocco - the DTUK box makes you notice the difference though. I was initially expecting far better fuel economy as I was hoping that there’d been some actual technological advances in the way the TDI uses its fuel rather than just the addition of stop-start which does very little for my uncluttered commute. I’m happier to get 45mpg with a heavy right foot than maybe 15% more by driving like a nun, especially with the DTUK box added. Next time though I might decide to sod the fuel economy and get an S3.

Had the advantage of having back to back Audi Quattro 170BHP TDi so knew could mix decent performance with excellent fuel economy
This balance is what imagine most people buy their GTD for as you not sacrificing one aspect over the other.
Colleague has a vanilla GTI and there are only a few occassions where I truly notice the difference when he pushes on or accellerates in certain situations. Most of the time the drive is comparable even from a sporting aspect except in mpg.
There are other considerations such as C02 for company drivers which makes the GTD more financially attractive but think fact you are getting GTI performance from not so long ago with Bluemotion economy from not too long ago has the GTD as the perfect combination.

My financial savings were hard to overcome this time around when packaged them all up and its a nice feeling to be sitting in the GTD and not being punished for the pleasure financially.
However my circumstances and mileage may be changing in next couple of years so could also be looking at petrol options too though do not like the S3 styling of Sportsback so likely a GTI or even an R in 5 door would be my options.
-
Thanks for the replies all. I take a car allowance from my company and they specify either diesel or hybrid with CO2 emissions no more than 160g/km. The GTI came in below this figure but as it's petrol they would not allow me to purchase. My previous car was a Skoda Superb 170 DSG elegance with 157 g/km and this was fine. I am sure the GTI comes in under 140 g/km and tried to argue the case to no avail. I'm glad it seems i am not missing out too much and i do enjoy the car.

A woman where I work has ordered a gti with pp for her lease car (it's actually a salary sacrifice scheme) and the only stipulation on our scheme is that all cars ordered must be below 150 g/co2s. Quite why she's ordering the pp for something she won't be keeping and never track driving is beyond me but it's her money.

You can keep cars when leasing through salary sacrifice on the scheme I am on with tusker. I am at the end of a 3 year lease and had the option to purchase the car if I wanted. I chose to give the fiesta back and upgrade to a GTD instead.

You can keep cars on any scheme not just salary sacrifice scheme (local authority so not sure if all schemes are like this)

i am reading this with interest, my white GTD is on oder.
Currently I drive a VW California Beach, basically a VW Transporter with a 115bhp Bluemotion TDi engine and some start stop stuff, which makes absolutely no difference.
Turning air con off makes a big difference, also sitting at 60 makes a vast difference compared to 70. My experience has always been that cars have a sweet spot for MPG, but who wants to drive t 60 all day?
I had a Volvo C30 before the California and I loved that car, but the 2.0 Diesel, powerful as it was for its time never really returned much more than 44 - 47 on a run and around 36 - 38 around town.
With my Beach i tend set my MFD to number 2 and record an average over the month or the week and that works out about 36 mpg - or more painfully - I spend about £70 a week on diesel.
Any improvement with the GTD would be welcome.
I am not a quick driver, so expecting some gains. Very interesting point raised about ACT, I do suspect that is where the future lies and I was very interested in the Polo Blue GT.

At 9000 miles (14400 km) total mileage best tank is 624 miles on 10 gallons (1005 km on 45.63 L).
Trip computer shows slightly over calculated mpg, 64 mpg (4.4 L/100km) vs calculated 62 mpg (4.54 L/100km).
Best trip on got me a calculated 76 mpg (3.7 L/100km) over a distance of 53 miles (85 km).
Now that I have tested driving in eco mode I can revert to my more normal driving which gets me more like 50 mpg (5.6 L/100km)
Car in eco mode, AC and everything else on as usual but no using the cruise control.
-
Does eco get you more MPG? I've never tried it as others on here claim it gave them less.

1. ECO cuts engine responsiveness and 2. As soon as you take your foot off the throttle, still in gear, the revs drop to minimum, even at speed giving a 'coasting' effect. If the 'instant' MPG is selected you can see this effect as the figure will jump instantly. Contrast this with D and S where the engine revs will still be commensurate with road speed. 3. Cornering lights are cancelled in ECO as well. 4. If is in ACC Cruise Control, it takes a lot longer for the engine to regain the previous speed after an interruption whereas in S the regain is almost instant. This does help slightly with MPG but is it worth it strangling a high performance Golf to save pennies?
HTH but it's all in the manual...
-
Eco can give you more mpg if you are prepared to drive like a nun, but more often than not it just frustrates and you end up putting your foot down harder.
-
Just collected my GTD yesterday, so will be chipping in with my calculations as the mileage goes up. During the week (on company time!) I'm hoping for above 50mpg - this will allow me to have more fun at the weekend!
-
First tank out of the way. Brim to brim calculated mpg of 48. Mixture of driving, ACC used temporarily, Air con used constantly.
Fairly happy with the result, I'm just hoping it improves slightly as the engine mileage increases and the initial new car feeling goes away!

It will improve. On Thursday last week made a trip to Aberdeen, prevailing temperature of mid 20s C, very hot and sticky. Climate Control on constantly, set at 17ºC after being at LOW for initial 15 miles to get comfortable inside, ACC on constantly.
Round trip of 278 miles averaging 58.7 MPG, in Sport constantly...DSG and engine. Not bad.
Last October I toiled to get above 48 MPG!
-
That's because it was October. With modern tolerances you'll not see many running in gains beyond 1000 miles, the gains being seen right now are down to heat and humidity giving more expansion for less fuel under combustion. Motorway speeds mean very efficient aircon - so much air hitting the aircon radiator to remove compressor generated heat and the system has to work much less than trying to get the same effect at 40mph.
-
First long run today, Chesterfield to Lockerbie, just under 200 miles ACC 99.9% of the journey, 49.9mpg by the computer.
Only had 675 miles on it when I set off and previous to today only been running around locally.
Peaked at 52mpg (probably due to the 50 zone on the M1) had it in Individual with all set at Normal except for ACC which was set to Sport.
Long term, after 788 miles, is 42.8mpg and it hasn't been out of Sport until today, bit of a drop from mid-high 50's in the Passat I've just got rid of.. good job I don't pay for it :whistle:
I'm hoping for above 50mpg - this will allow me to have more fun at the weekend!
Stop hoping, unless you drive very carefully (and slow).. and the fun never stops, even when you are on company time :laugh:
-
Business or pleasure in Lockerbie. I've got relatives in Lockerbie so visit quite often.

Business.. back next week too.
Had it in full Sport mode (inc DSG) all the way back and got 46.8mpg indicated don't know why I bothered changing it, might try Eco next week just to satisfy myself that it should stay in Sport :cool:
-
Mine is behaving well as of late, in the luscious weather.
New record for me on Tuesday coming home from Loughborough.
(https://dl.dropboxusercontent.com/u/4147571/gtd/IMAG2392.jpg)
Had the journey been longer it would have been much better as i came off the motorway with a solid instantaneous 71mpg, and having average 64mpg. A few traffic lights and some slower roads gave me the above average by home. Was v happy with that. All on ACC but no aircon needed as car was nice and cool.
Previous trip had been down to Worthing and back (150ish each leg). Disastrous trip down with tons of stop/start on the M25 after a vehicle fire and 90 mins of queuing saw 46.5mpg. Worthing to Rugby with some sticky traffic on the M25, aircon on the whole way home (3 hours) and ACC all the way on the motorway gave 55mpg. Oil temps over 100 for the entire of both journeys (anyone else find this in the warm weather?)
-
I think in this weather air con has quite an effect. Been out today up to Wallington Hall and just managed to crack 52mpg's on the way up. I wasn't caning it at all as had family in. On the way back the car was hot so had the windows down and air con off for about 5 miles and got an easy 60mpg. On another note for some unknown reason my long term figures have reset themselves. They had been going since day 1 of ownership and now they've gone. Not very happy.
-
.......On another note for some unknown reason my long term figures have reset themselves. They had been going since day 1 of ownership and now they've gone. Not very happy.
I've read on the forum this happening to other folk. They seem to reset after a set period / mileage.
-
The reset happens after so many hours of driving - it's in the manual somewhere. It usually happens to me around 2000 miles.
-
Well all I can say is my long term mpg's must be a near constant figure as I've never even noticed it re setting before.

Yes!

I can get it into the mid 60's on my commute to work driving in Eco. Whereas the same route and driving style sees me get 52mpg if on Normal.
-
Maybe eco gives the best gains when driving very conservatively, whereas hoofing it in normal will be more economical than hoofing it in eco? I'm usually hoofing it. :grin:
-
Yeah that could be a valid point. The odd occasion I've had it in Eco I have driven extremely
carefully boring but it was really just to see what it could give me.
-
I found Eco a complete waste of time. Made the acceleration feel as sluggish as my old 1.4 Ibiza and no gains to MPG on my 35 mile commute.
-

Majority of my travels are motorway bound anD trying to keep up with traffic in ECO does seem to have a negative effect compared with NORMAL.

-
Just broke the 500 mile tank range mark. I managed 517 miles with an indicated 56.7mpg on the computer. Mostly driving 80mph down to Essex and a faster drive back. Had climate on and set to 19c the whole tank. This car/engine really does seem to like the long runs at higher speeds.
On a side note I had it in Eco going down and sport coming back up and the mpg didn't seem to vary at all, pretty much the same :/ only noticeable difference was the sluggishness in Eco mode.
-
Wow! Forgot how sh!te my mpg is without my DTUK box on and no Millers in the tank. On the way to Pulman for my first service after dropping the missus off at work, 23 mile trip, pretty restrained driving, 16C ambient temp.....46mpg indicated.

Is that mpg calculated by yourself? Or relying on the trip computer. Its just I've found the computer seems to inflate the mpg by around 5%

Another tank bites the dust - 47.5mpg; giving an average of 48.6 over 2300miles. (Not bad going for 3 weeks!).

3500 miles in and I managed an all time best of 63mpg on a 140 mile motorway shlep yesterday.
Seeing my normal daily MPG fall though. Guess it's down to the temperature getting lower.

In 16,018 miles I have averaged 47.26mpg with a best tank full of 54.13 and a worst of 31.41...

Worst tank - was that a lot of fun or stuck in horrendous traffic?
My best has also been about 54, going from Newcastle to Leeds and back taking care of about 40% of a tank of fuel doing an average of 57mpg for the 210 mile round trip. Don't think i've got less than 39mpg on a tank though, even when hammering it. I bet I never see 39mpg with the R on the best tank.

God knows what mpg I would get in an R. If your ever in merseyside and you see a black gtd creating a sonic boom as it hurtles down the road, that's me. :evil:
Average speed of 19mph would suggest otherwise... That suggests sitting in traffic an awful lot or just sitting on tick over...
-
I've only been on the motorway 3 times in my car as I have a works van plus we put the miles on the wife's 2005 golf. I just use the gtd for goin for a quick blast around the town. Maybe the sonic boom thing was slightly over enthusiastic but I certainly don't sit round for three hours a day with my engine running. :rolleyes:

Hi,
After about 15k miles and a lot of care I could finally get 50-55 on a motorway run with a bit town driving at either end. Cruise on at 75 with little traffic. Not a patch on what some of you are getting but the manual box seems less efficient from what I can tell.
Anyway, my car went in for it's first service a few weeks back and since then I honestly can't get 45mpg on a 100 mile motorway run with clear roads.
Checked tyre pressures, outside temp seems reasonable 10-12 degrees and I'm the only person in the car (with a bag).
I have asked VW but they say nothing could cause this... Annoyed as I feel I'm back to square 1 with this now....
Any ideas??
Wrong oil perhaps??
Thanks
Mike

Probably the software update. A few folk have mentioned their MPG going down after a service.

I'm pretty certain I've read it on this and other forums before, but I think at around end of October / beginning of November, the formulation of diesel being sold is switched to winter diesel, which includes additives to stop it 'waxing' in cold weather.
Winter diesel is less efficient than summer diesel. In previous years, I've noticed an increase of between 5% - 10% in fuel consumption when the fuel companies make the switch.

The 10% extra thirst is as much down to the weather as the formulation, if not more so. Colder air is drier air, it has a lower moisture saturation point. You'd be amazed how much humidity contributes to fuel economy. Warmer air saturated with moisture (as we see in the summer) expands more when combusted - giving a bigger expansion per combustion and better mpg as a result. With the colder weather you will also find your car takes longer to warm up - it may only be an extra mile for warm-up, but on a 10 mile journey it'll be noticed. You'll likely be using your lights, heating and ventilation more, all of which put an extra drain on your battery, so your alternator will be working harder.
-
Yeah I agree to an extent and appreciate that the economy in the winter is worse but I have had my car for about 13 months and 16k miles. The economy I got last October when I first got it was about 46-48..
Now I cant even get that and it's the worst it's ever been so I'd have to suspect that something is wrong. It isn't even that cold - about 12 degrees.
I'm driving it as carefully as I can and still struggling to break 45 mpg on an 130 mile motor way run.
It is honestly like a different car since being serviced..
reading a lot of the sales patter about low friction lubricants etc being developed helping improve fuel economy I wonder if they have used a diff oil?
Love the car, hate the performance!!
Surely you can get nearly 40mpg out a Golf R!!
-
Mike f: Yes my car is a thirsty beast post-servicing, getting 43mpg ave right now. Can't wait for the R now, at least when my mpg dips below 40mpg when it gets really cold, the mpg shock of the R won't be as big as it was.
This GTD has by far the worst fuel.economy of a VW TDI I have ever owned, I'd be getting a solid 50mpg in my Scirocco right now for these weather conditions.
-
Mine is a manual GTD, just sitting on 6500 miles at the moment as it sits around quite a lot lately.
Took it 140 miles to Preston at the weekend, it managed 57.7 on the run, which is good given that it's about 30 by the time i reach the motorway (all uphill). That was at cruise on 73 all the way.
Coming back it was quite a bit faster, 75-80 on cruise with a few moment of foot down action, stopped once briefly ahead of M6 toll. Managed 54.5 coming back.
Seems a bit more effortless than when i first got it, but have still only cracked 60 on a couple of occasions. The DPF is a nuisance though, no rhyme or reason to its cycle. Only significant pattern is it always seems to initiate one after a long motorway cruise, meaning i arrive at destination with fans on.
My biggest irritation is VW diesels were always famed for meeting their combined MPG figures with ease - then i buy one and mine is a mile from the book figures really. Only once has it come close!

I would be delighted with that consumption. I cant even hit 45mpg cruise on at 75mpg on a 130 mile motorway run with flat-ish roads...

Just got my car on Thursday, and covered 320 miles so far. Noticed that comfort mode and using radar cruise control to assist I did a return journey with 50.9 mpg actual return mpg on 162.7 miles journey from home to Newtonmore and back. Saw a best of 55.7 average for a time, then Cairngorms put paid to that.
Impressed with the technology so far and betters the 36.3mpg I got doing same route in my Mk5 GTI by a useful margin if I can see this type of return regularly! :smiley:
No doubt will drop off if listen to rock or dance music and select sport mode, but find it gets annoying after a while with pseudo V8 sound track and Sat Nav directions getting piped through louder as well for some reason. Also why does it think I want to go to Wolfsburg when I change to 3D view and then lose my current destination? Weird? Bit off topic but in my mind to mention it! :huh:
-
Wolfsburg is its maternal home so probably just missing it!!
Seriously though this was a gremlin in some of the old RNS510's sat navs.
I've never experienced it on my Nav. Maybe worth mentioning to the dealer?
-
I've had my GTD for nearly 2 months now (2200 miles on the clock), mpg wise it is showing 49 long term - mix motorway and town. Long motorway trips returning 53 ish, confirmed by brim to brim test.
Overall i'm quite pleased, not as efficient as my last car but ok and a lot more fun to drive.

Just wait until it gets serviced, you might see your mpg drop a bit.
-
Hmm, mine had it's first service about a month ago and also had a software update done (recall ?), and on the 2 fill ups since, according to my fuelly account, the MPG is pretty much identical (to within an mpg) before and after the service @ 46-47mpg average.
-
Ive had 3 days in a row of abysmal mpg (42mpg indicated, which is like 38mpg in reality with the DTUK box overstating). The car seems to be regenning towards the end of every journey. I filled up with Shell, my GTD really doesn't seem to like it.
-
Also why does it think I want to go to Wolfsburg when I change to 3D view and then lose my current destination? Weird? Bit off topic but in my mind to mention it! :huh:
Mine does exactly the same, I reported this when in for its first service last week and dealer says there's a software update which they've ordered. Its due to be installed in a couple of weeks although I can't believe they want my car for half a day to do it :rolleyes:
-
Coming up to a year and just about clocked 9000 miles which was less than expecting but work demands have changed and less miles needed.
One of advantage of a fuel card is that can see exactly how much fuel put in over that year.
Imagine I am the typical driver, mainly local and medium journeys with the monthly long distance (usually get 50-55 MPG)
So after doing all the sums my average MPG for the year was 39 MPG which think is pretty good given journeys make and occassional driving style.
-
My GTD is definitely struggling at the moment. MPG seems to have dropped quite a bit, I'm guessing largely due to the oil taking ages to get up to a decent temperature. I'm beginning to wonder whether driving it a little harder from start up would help.
Mind you, if I was feeling a little downbeat, I was talking to a workmate who is pretty much doing the same journey as me each day and he is currently getting around 20mpg from his R, compared to 38mpg from my GTD. Ouch!
-
I have a 3 mile stretch of 70mph road before I hit a 60mph dual carriageway for most of the remaining 9 miles to work.
I've found if I push the car on the first road it has warmed up considerably more and returns more MPG by the time I come off the dual carriageway than if I take it easy on the 3 miles stretch.
-
If I drive it like a saint (lots of lift and coast) I can, or have once achieved 69.9 mpg over a 60 mile drive. Usually get around 55mpg which is a little better than our 1.6 tdi Fabia so quite happy given the fact the GTD has twice the BHP!

Right, just to give some real life figures, I've been plotting all my fuel usage in the Fuelly website since day one. Here are my figures after 13 months of ownership. These are calculated from fuel receipts and brim to brim filling, although to be fair my fuel computer is rarely more then 1mpg out (massively more accurate than any previous VW I've ever owned).
Bear in mind, I've only had one long motorway trip in the car, and 80% of my mileage is city commuting with the inevitable crawl and traffic jams. This is not a high mileage motorway muncher car. Mine is also a DSG (thirstier than a manual).
Total Mileage tracked 9,591
Overall MPG - 45.5 mpg
Overall (last 10 fill ups) - 46.8mpg
Best MPG - 55.6mpg
Worst MPG - 45.1mpg
Last fill up (25/10/14) - 47.8mpg
-
^^ A worst of 45.1mpg from a tank isn't bad IMO. I don't track it as religiously as you (or at all in fact), but I'm sure I've got around 38mpg from a tank on a few occasions.

With the colder weather I have noticed my MPG taking a dive. In summer my long term average was a steady 52 - 53. Hit 60 on a couple of trips. Now its hovering between 45 - 47. Maybe the winter additive in the fuel and the lower temps. No changes in driving style or journeys etc.

Strange, I've not noticed any significant difference... but then the weather hasn't been that cold (15-17C generally)...

Mine seems to be consistent at circa 50. As said the weather hasn't really turned cold yet. Although lights and heater etc are now on for longer

Pretty similar here according to fuelly

Those will not make a measurable difference...
Do you notice that your car is significantly slower when you have your headlights on, or if you turn the heater up a degree or two or if you put the heated rear window on? :laugh:
No?
Then you won't be able to measure the effect that having them on has on the fuel consumption... it makes a bigger difference if you have a passenger in the car or not... :tongue:

Of course lights/heater will effect the mpg achieved. They are putting a load on the alternator. Depends on your definition of "significant".
-

:rolleyes:
By any definition of significant.
You could not measure the difference in mpg between having your lights on or off and attribute it to that, the wind direction would have a greater impact than having your lights on. I don't notice a sudden change in performance and fuel consumption when I turn my lights on... and a change back when I turn them off.
The heater has no impact as this is driven by the cooling system.
-
I think most people would consider significance in change by how measurable that change is . Some people might notice a 2%/1mpg change on a GTD, others a 5%/3mpg change. There are so many variables in the mix with a car:-
Wind direction, ambient temp, having an extra passenger or cargo. I personally wouldn’t consider the lights significant, you have about 140W of external lighting in total (not using fogs), and around the doors your engine will be typically outputting around 60kW to achieve 45mpg. Your lights are eating away about 0.25% of your total output, you couldn’t confidently measure the change in mpg with all the other things going on, like a change of direction into a headwind etc.
Start adding aircon (up to 3kW/5% max) or heating (wing mirrors, rear screen, blowers on the auxillary heater) on a car with a cold engine and you might be talking 2kW/ 3%. Once the car is up to temp you should only be relying on the engine’s heat output that is normally wasted to the atmosphere via your cooling system. On a cold engine you’ll definitely see the heating/aircon effect (to keep windscreen from fogging) on your mpg. On a cold day though, you’ll also have to ask yourself how much of that 5mpg winter dip is down to the ambient temp and the engine working harder with slightly denser fuel to get up to temp from a lower temp and combusting with the use of drier air (less expansion – humid air has a positive effect on mpg), and how much is down to the ancillary load being placed on the car either directly (aircon driven by a belt off the engine) or indirectly (higher electrical load taken from the battery that the alternator is going to have to work harder to put back at some point, not necessarily immediately). You’ll notice the aircon’s effect on your output immediately if its working hard, the electrical systems perhaps not.
-

That's the correct answer...
-
Can hardly believe how a little bit of cold and not having the DTUK on have hammered the indicated mpg. I struggled to reach 41mpg coming home today, most likely a real world 39mpg, as opposed to yesterday when the box managed an indicated 51mpg (likely real 47mpg) driving the car much harder. No heating on at all and 9C (yesterday it was 12C). Missing the box already (my dad has a lend of it).
-
Does the DTUK actually increase MPG? I would guess it will mess with the MFD figure, have you checked the MPG manually (ie mileage vs number of litres you sling in)?
Genuine question there, not a dig :D

It definitely increases the optimism of the MFD reading, from around 3% stock to around 9% with the box on (as per my numbers above), but my car definitely seems more economical with it on (taking the optimism into account), which I suspect is mainly down to far fewer DPF regens which give the MPG a real kicking. I have really looked into it in the early days with and without the box to come up with those 3%/9% figures from brim fills.

Out of interest Matt do you still use the derv additive, Millers Oils?
I've stopped using it and I don't know if its my imagination but my car feels rather sluggish now in the low rev range!

Yes, still use Millers, i'm 1/2 way through a big 5L can. I can tell when there's none in the tank.
-
I think I'll get some more.
My problem was the smell of it and the smell on your hands after putting it in regardless of how careful you are.
Any recommendations for the 5L can?
-
There was a case recently in the states about Hyundia / Kia claiming real life mpg for new cars that turned out to be incorrect, this resulted in a large fine, the difference was 1 or 2 miles. Maybe it's time UK customers took a court case against VW for their diesels.
-

There was a place online I got the 5L can from that was cheaper than everywhere else....Watsons? I really can't remember. It ended up £60 delivered for the 5L can as opposed to about £75 elsewhere.
It is an evil smell. I can smell the residuals of the last lot when I run the tank down to 20 miles left and fill up again.

All the UK car advertising now has arse covering messages like "67 mpg combined*" "* test conditions only, may not reflect actual mpg achieved on the road". It would be very difficult to sue them for misrepresentation now.

Sounds like rumour dressed as fact... 1 or 2 mpg difference could easily be down to driving style, weather conditions or whatever... You could try taking them to court here but you would fail.
This is the UK (or more correctly, in this case, EU) not the US and the manufacturers have to use the official test figures in advertising. And because they have to use those figures they make the cars very efficient in for those tests which are run on a rolling road, at a set ambient temperature... etc. hence why more and more cars are fitted with stop/start systems... The cynic in me thinks that cars may even recognise the test conditions and behave even more economically...
I'm sure that I read somewhere that there is a new more representative test coming...

We just picked up a 2014 GTD DSG. Before we owned a VW CC and official figure was 53mpg combined, on the clock we got about 49-50. So looking at the GTD thought we'd get a bit more and have the power if required.
However, we've had it for a week and in economy mode, with as much coasting as possible and driving on long motorway drives at 60mph with air con off, I cannot for the life of me get it above 43mpg?!
Scanning over some pages of this mammoth thread and most are seeing much more than this with normal driving never mind my attempts to try and hit high mpgs.
I have reset the long distance clock since we got it and done every economy driving method I know in economy mode, so not being able to get over 43mpg (AT BEST!) seems wrong. Anyone know what might be up?
The car has done 4000 miles and was an ex demo at the VW stealers.

It's the con of start-stop having a huge effect on the test cycle. Before start-stop (like with your CC), you could easily get within 5% of combined figures without driving like a nun. Now you should be realistically aiming to achieve 70% of published figures around the doors and 85% on a long motorway run without driving like a nun (figure 75% and 100% if you are driving like a nun). Look on the bright side, you might not be saving 20% on your fuel bill as you thought you would, but you'll be saving around £115 a year in road tax. Happy about that? No, me neither! :grin:

The CC had start-stop too...
-
Maybe the results obtained for the CC were done on a testing regime not optimised for start-stop? Not sure when the current testing cycle came in, but it has 24% of it's 11 min time with the car at a standstill. The only way to achieve 67mpg in the GTD seems to be driving at a constant 60mph on a long motorway run. Your "low" mpg aves reported here aren't atypical.
-
There seems to be tons of factors that effect the fuel economy on the GTD.
Temperature seems to be a major factor as does winter derv mix (mine has gone from typically getting about 49mpg to 43mpg in the last few weeks), another seems to be that motorway speeds aren't what its best at (I get far better economy from A roads, which should you'd like to think give you worse!) and lastly the dreaded oil temp thing that means that probably up to a 15 mile commuter trip from cold will be super crap.
I drove my GTD to the Netherlands earlier this year. 25 degrees air temp, 600 mile trip, 80mph on ACC down the super flat motorway, no traffic jams - 63 mpg.
It is possible to drive it like that, its just that your usage may vary.
Back to the UK, my drive home from the ferry port was only 48mpg...

I'm not sure what you mean? The CC is supposed to get 53mpg combined. I got 49-51. It had start-stop, it was a 2012 model. The GTD also has start-stop its supposed to get 62.8mpg combined, i'm getting 42.
I'm getting 42mpg driving at 60mph on an hour long motorway run with air con off in eco mode, coasting as often as possible down hill.
Doesn't seem right? People here are suggesting they are touching 70 in ideal conditions. I literally can't get it past 43!?
-
Also - don't use eco mode. Eco mode does nothing positive to MPG.
Eco mode I am convinced is an MQB mode for the electric/hybrid vehicles concerned with reducing electrical consumption, not derv!

I'm not sure about that, the eco mode controls multiple things, engine map, steering, suspension (I think), light bend and air con, plus you can customise all these. There is the biggest difference i've ever experience in any car between the three engine modes of Eco, Normal and Sport. Massive differences, in most cares even normal to sport is fairly subtle.

I don't believe engine modes alter the engine map... I think they only alter the "throttle" map... So for a given press of the peddle you have less "throttle".
The other things, apart from aircon and suspension, you mention all change the electrical load - which in the case of these items make no measurable difference to fuel consumption... Aircon has the greatest impact on fuel consumption and I don't really see what effect changing the damping to soft has on fuel consumption...
-
The modes on the golf definitely do not change the engine map as corgi had said it only changes the throttle response. I never use eco mode as it gives the worst mpg figures no matter how you drive it. I'm sure the coasting function only works on dsg models too and with the drop in outside temperatures that'll knock about 5mpg at least off your combined figures.

I'm with mcmaddy here. Eco gives me poor MPG compared to sport.
Why don't you try it for a week driving the same way as you drive in Eco and give us your findings.
Is it possible it hasn't been run in right if it wasn't bought from new?!

Very possible, it was a showroom demo car - it'll have been ragged to hell and back.
I have turned off eco mode for now - seems a bit bizarre to have an eco mode if it doesn't actually get you anymore economy. At the moment i've put it onto individual, everything sport but with normal engine. I find the sport engine to be a lot more roary and noisy - I can't match the same sound in normal mode even with the same revs.

It will be more roary in sport because the sound actuator is active when sport engine mode is selected.
-
I find I improve my mpg by using Eco mode. Not because the car is more economical (never measured it, so will take you guys word on that), but because I change the way I drive the car.
Knocking it into Eco I switch to an eco driving mentality, and avoid heavy acceleration/keep revs low. So works for me anyway!
It's hard not to give it some welly in Sport mode :)

That makes sense. So sport mode activate the full throttle response and the sound actuator, anything else? Obviously higher RPM gear changes on the DSG as well.

Haha same. At the moment i've gone for an individual everyday map with everything in sport except engine, which is in normal and air con in eco. Will see how I go on. It makes for a nice daily driver anyway, but have only done a few short journeys and now down to 39mpg. Must admit, really not impressed at the moment, seemingly feels like I might as well have got the GTI!
-
My long term MPG is 38.5 but I do keep it in Sport mode 99.9% of the time

Well this weekend the car had only it's second decent run. Went from home (in Cheshire) to Cardiff, saw our nephew for a few hours then on to some friends in Swansea for the rest of the weekend.
I had the ACC set to 70-73mph for pretty much the whole journey (M6, M5, M50, A40, A449, M4). Had about 40 minutes of standing traffic in Cardiff city centre (due to the big rugby match on Saturday - Wales vs S. Africa), then onto Swansea and about 50 miles of various tootling around over the weekend. Then on the way back had a fairly good run until we got to within 5 miles of the M6 whilst on the M5, where it crawled for the 5 miles then for the next 15 miles due to the roadworks - 50mph average speed camera section (is this road ever not busy - even at 9.00pm on a Sunday ?).
So, what did I get for my 497 mile round trip. Well the computer said 58.4mpg since fill up, and on going a brim to brim fill, I calculated it at 57.9mpg (so the computer is pretty accurate).
Car had 10,500 miles on it (now at 11,000), and for a DSG, I don't think that's too bad ?
-
Excellent results Andrew
-
I'm quite surprised that those what with the ambient temp right down this weekend and you've also got the winter mix derv now too...
I've gone from easy 48-50 mpg over the summer down to 40-42 mpg in recent weeks.
Pretty much the same journey every day too..
-
In the last 2 days i've gone from 42mpg to 48mpg on my commute - driving like a nun (not quite, but holding back) right now as my neck is pretty achy from Sunday's accident with the GTD, despite the ambient temp dropping from 10C to 5C on my way to work.
-
I've not noticed any change in fuel consumption in recent weeks... It is resolutely the same...
I suspect the winter difference may be because on shorter journeys a greater percentage of them are spent warming up..?
-
I've noticed a slight drop in MPG on my usual commute to work as the temperatures have dropped below 10°C (some mornings it's been only 2°C). To be fair though I've just put this down to a) Having the heated seat on (love it), b) Having lights, heated rear windows / mirrors etc on, and c) with the climate control temperatures set at around 27-28°C to heat the car up quickly, the 1kw ancillary PET heater is probably activating for the first part of my journey.
For my trip down to South Wales, my fuel was BP's regular Diesel (not premium), as it' the cheapest around here, and ambient temperatures were actually not too bad at around 11-12°C for both days.
-
I still think that unless you are traveling a reasonable distance (say 50 miles) the biggest thing thats going to hurt is the warm up from cold, which when the ambient is less obviously takes longer.
One thing is for sure, the sub-optimal consumption on "from cold" trips combined with DPF regens certainly means that this car is not for people with short urban commutes!
-
I do 3 miles to work and 3 miles home and don't have any problems at all. Mpg during the summer 40ish, mpgs now during the cold 35.
-
Wow! A new low for my GTD - the roads are empty this morning - zero congestion, reasonable ambient temp for the time of the year (7C), wind blowing from behind be 90% of the way and the car does an indicated 37.2mpg, a likely actual 35.5-36mpg. What do they put into winter diesel to "water it down" so much? It would not surprise me in the least to find that winter diesel has only 85-90% of the stored chemical energy that regular has.
-
What a surprise. Driving to the Metrocentre after work and a spirited drive back (someone in an Audi A4 170TDI trying very hard to undertake me) and I realise i'm approaching 50mpg for the trip, what is going on? 14C ambient temp, I could hardly believe it for early January. Just goes to show what a difference ambient temp can make.
-
This cold weather is destroying my MPG at the moment - struggling to get above 30mpg in mixed driving!
Would some Millers potentially improve it?

It's no miracle brew - it won't suddenly up your mpg by 20%, but you should see a 5% gain and smoother cold running - if your mpg is being hammeerd by more DPF regens then you should find the Millers helps on that score too.
Your 30mpg is going to depend a lot on how far you drive the car and how you drive the car. If your commute is under 8 miles in this weather, if you drive it hard then you'll be generating a lot of soot to store in the DPF.
-
My MPG has improved since the cold weather started but that probably has rather more to do with me swapping the Bridgestones to winter tyres (Ultragrip 8 Performance).
-
I got an indicated 56mpg average after a 30 mile trip yesterday. I was very surprised - although the car had been idle for three hours having been warmed up earlier so that helped...
-
My new GTD arrived 10 days ago and after 1000 miles since delivery 2 things that have surprised me are that I have never averaged over 40 mpg on any journey and the range has never been above 400 miles after filling it up 3 times. Admittedly I have had the heated seat on an awful lot due to the cold weather but these figures are still quite disappointing.
Despite these niggles I am absolutely delighted with the GTD and the company fuel card means that I can't really complain but I would be slightly disappointed if it wasn't a company car.

This will not make a significant difference...

Since delivery, in all driving ~24K miles I have averaged ~48mpg...
-
Just checked my stats. I'm averaging 45mpg at the moment. Been pretty much the same all through winter. Wish there was a manual method of forcing a regen. Nothing worse than ending a 100 mile journey then hearing the fans still running.
-
Yeah, it would be very useful. On several occasions recently I've pulled up at home and the car has been mid-regen. I'd normally take it for a spirited drive but the weather hasn't allowed it.
-
My runs to Heathrow and Wycombe and back in recent weeks have easily attained 55mpg with a mixture of 60 roads and motorway. I always use Eco for the long trips, as i prefer the way the cruise control reacts as opposed to anything else. I might leave it in sport to go on the 120 mile round trip on friday and see what i get. I find that any long run of any sort seems to do a DPF regen, it just likes the opportunity i guess.
She is approaching 10k miles now though, whereas sub 3-4k the economy on long trips was poor. I do notice though, that i've changed my driving a lot since getting the golf. I read the road a lot better in anticipation, coast up to junctions where before i was off the loud pedal and onto the brakes etc. I'm not afraid to hoof it though. :p I'm at the point now where she is attaining good economy, and can get somewhere near book on a long or summer journey, as opposed to the howling 40-44mpg i was getting on early runs.
-
Hello fellow-GTD-NB'er C2K - only 3 of us on the forum that I know so I have to say hi when one pops up :)
I try and use Eco on longer trips too, happy with 50 on most. Although recently have been doing mostly A roads with quite a bit of hoofing, and averaging 45 (the cold doesn't help too.)
How can you tell when it is doing a DPF on the motorway? Other than hearing my fans running on stopping the car (only happened once to me) I'm non the wiser to my car doing a DPF!
-
only have my gtd a month with 1500kms on the clock so far.
car was only averageing 41.5 mpg in the first two weeks on mostly short trips during the week with some longer 50/70 km weekend trips.
last week or so its steadily rising to 47mpg though , mostly in eco mode atm due to freezing weather conditions here. if i can get to 50mpg or so ill be happy. the vw quoted figures seem to be fantasy though :rolleyes:
-
Hi Corgi,
Most journeys are motorway driving at least 30 miles with a couple of 100+ mile trips, always in normal mode. I thought it was my driving until I got in straight after the wife had been out with her 80 year old mum on a 40 mile round trip and was amazed to see she had averaged just 31.8mpg!!!
On my previous Golfs you could toggle between "trip" and "since reset" figures on the trip computer using a button under the wiper stalk. I can only see the "trip" info at the moment which might be a false reading as I only check it when I suspect it will be low!!
How did you view an average over 24k miles? Is there a way of checking long term averages on the mk7?
-
Hi tobydon, you can go to the car menu on the media screen and select view car data (something like that.)
You can then scroll left and right to see since refuelling/long term/trip.
Your wife and her mum - obviously were doing doughnuts in tesco carpark!
-
On my previous Golfs you could toggle between "trip" and "since reset" figures on the trip computer using a button under the wiper stalk.
With the MFD showing Avg. mpg you can scroll through 'since start', 'since re-fuel ' and 'long term' simply by pressing the 'OK' button on the right of the steering wheel.
'Since start' in this instance means start of the current journey.
You can also get the info on the central infotainment screen as described above - although its not available there once the low fuel warning light comes on
-
Had my DSG GTD now for about a month. Long term average is 49.5 and I've got 53.2 out of my last tank.
My daily commute is 50 miles one way (Stoke to Derby on the A50) and I always have it in Eco and don't usually go above 60mph. Some may laugh at that but I'm never in a rush to get to work so just take my time. The benefit of that is I can average 59.8mpg over the two journeys! Still not managed to crack 60 yet though :angry:.
The fuel that I save driving in this way I then use up on the B roads once I get off the dual carriageway :evil: which then brings my average down to about 50ish. I think if I drove at 70-80 on the commute to work I would get about 45 maybe 50 if it was clear.
The car has done 9k now so can still probably loosen up a tad more which may see me crack the 60mpg barrier on my journey to work, but still not hit the official figures. Initially I was a bit disappointed, I thought I would have been able to get 60-65 on the long journeys but now I'm not really bothered. Love the car and the performance (I don't drive like a Nunn all the time) so happy with what I'm getting.
-
At my last fill, I was in 24,458 miles with a combined average in all driving of 47.33 (calculated using Road Trip)...
The best tank's fuel consumption was 54.13 and a worst of :embarrassed: 31.41 (some b-road fun and then a long time sat in traffic). It has stayed fairly constant over the winter. The only difference I notice is if I let my lead-footed girlfriend use it... she averages about 42-43 on her commute (motorway and then queuing to get into Nottingham).
-
Still not managed to crack 60 yet though :angry:.
You will in summer - warmer temps should up your figures by about 5mpg!

I've got a Mk6 2.0 TDI 140 at the moment and am thinking of changing it for a Mk7 GTD at some point, both DSG.
The Mk6 is listed as about 53.3mpg combined and I always achieve at least that given most my driving is all motorway.
I see the Mk7 is listed as 60mpg combined which I think is unrealistic. However, is it a safe enough bet that I'd achieve at least the same mpg as I get from the Mk6?
Afraid I haven't read all 100 pages of this thread but would be interested to hear any opinions on the above :smiley:

I had a MK6 GT TDI 140 (mapped to 195bhp) and it regularly showed (MFD) 60 + mpg, real world fuel used calculations put this at more like 53-56mpg. The MK7 GTD (boxed, so 240bhp) I'm seeing nowhere near this ! More like 50-53 (MFD indicated) real world about 47-49mpg. At the end of the day this car has more bhp & torque so all things considered not that bad ! I suppose it's all relative really to expectations, but the claimed VW mpg figures are impossible to get anywhere near in the MK7 (as they were pre-box). Most of my miles are too motorway and I do not have a lead right foot (cruise on about 80 most of the time). hope this helps ! If you decide to jump to a GTD you won't be disappointed ! The Mk6 was a great car btw.
-
Thanks! I had a Mk5 GTI before and I miss its performance and sporty looks, so hoping if I get the Mk7 GTD it will be the best of both worlds

Hi J400, I think the mk7 GTD really is the best of both worlds.
I didn't have a mk6 (but always loved the look of them) so can't compare directly, but the mk7 is an all round excellent package.
You have the option of a DTUK too if you ever fancied it and it makes the car so smooth and powerful it is a delight to drive. I loved the car stock but it's just improved all round now :)
I did a 70 mile round trip today, mostly motorway and 1.5 degrees temp for the first leg (140 mile total trip). I cruised at 70-74ish, hit some spots of traffic, had a few bursts of power, and averaged 55mpg (probably 50 actual due to the box). Seems in keeping with your higher cruise Stuart and slightly lower mpg, good to know the cost if I want to get home for dinner early :D
My new tyres have higher rolling resistance too.
Long term average (11,000 miles) is just under 45 (pre box so not far off actual).
So yes, low 50's motorway is easy if you cruise at a reasonable speed :) keep us posted if you go for it!
-
After 2200 miles, I can only say I am very disappointed with the MPG I have experienced with my GTD. My LTA is sitting at 36.7 mpg with mixed driving of dual-carriageways (100 mile round trips) and town-driving, someway short of the book combined figure. I know this figure or anywhere near is unrealistic, however I feel that something around 45-50 mpg should be achievable. The most I have soon on a journey was just under 47 mpg, driving with extreme care.
The cat has been into the local delership and details sent through to VW HQ in MK and to Germany and they have told me there is nothing wrong with it. I've also had a long conversation with VW UK Customer Services just thus morning about it, upshot is the car is going to another dealer for another "check-up" when I get back from offshore and have also be offered a like for like extended-loan car to see what MPG I achieve driving it......
I rounded the conversation off by stating "are you telling me that my upgraded 1995 MK3 Golf TDi is more fuel-efficient than my 6 month old MK7 Golf GTD and engine-technology has not advanced in 20 years?", a car than until it was recently sold, could achieve 55-60 mpg combined every single tank of fuel with exactly the same type of roads and driving style....they didn't and clearly couldn't offer a reply.
I have found the MPG to be no different, poss. even slightly worse than in Eco mode than when in Sport. Having rear all the comments from other owners on the figures they have experienced, virtually all seem to be achieving higher MPG's than I am.
One of the main reasons I bought the car was the great MPG figures, and this was also quoted by the salesman as being one of the attractive features. However, after 2200 miles, I would be inclined to disagree. It's a real shame, but the bottom line is that if I thought I was going to get such low combined figures, I would have bought a GTI or R.
-

Welcome to the club! GTD owner going R very soon.
38-45 mpg in the Winter and 48-58mpg in the Summer. My 13 mile commute is the lower of the ranges, motorway driving is at the upper end. I freely admit I put my foot down, but once up to speed i'm pretty good at conserving my momentum, not racing towards roundabouts to jam the anchors on, good anticipation of the road (and cars) ahead. my Scirocco 170TDI was 10% more frugal around the doors, about the same on the longer journey. Thanks to EU6 emissions, the MK7 TDIs take an age to warm up and are thirsty whilst warming up.

How many people have 19" wheels with poor mpg? The dealer did warn me right away that this would really affect fuel consumption so I have went for the standard 18" wheels.

I had better fuel consumption with my 19" wheels fitted than I currently get with 18" wheels and winter-tyres fitted. There was only about 1-1.5 mpg in it initially (mpg went up with 18" wheels and winter tyres fitted initially but then went down but possibly more weather-related). In the grand scheme of things I don't think it would make too much of a difference unless your doing serious miles on a daily basis (which I'm not).

Interesting to know. The car I had on a 24 hour test drive had the 19's and I thought the fuel consumption was terrible only got 200 miles out of a couple of bars lower than half a tank. I was caning it sometimes though and was in Eco mode most of the day. Sport was getting better mpg.
-
My wheels are 18" and my mpg is still sh!te! :rolleyes: That extra 4.4% width on a 19" wheel can't make such a huge contribution surely?
-

Maybe the real reason is that it's too easy to enjoy the power of the car then. I have been testing my 3 series for the last week and altough I though i was getting 44mpg since I last reset I only get about 40mpg if I am lucky from a cold start and it's advertised as 62.8mpg
It also has a 61 litre tank compared to the golf's 50 litre.
-
I have 19" wheels and seem to get better MPG than a lot of people on here indicate.
-
I cracked 62mpg today on a 70 mile trip, 60mile motorway and the rest A road.
Obviously VW did their testing with a tuning box on, and the mpg over reading! :)
On a serious note, mighty impressed with my mpg and the DTUK, end of this week I will get a full tank actual read to compare.
-
Did my first actual MPG with the DTUK today.
Indicated: 57
Actual: 50.8
So 12% over-read, which rings a bell - I think Monkeyhanger quoted the same percentage at some point.
That was over 413 miles mostly motorway cruising at 75 with some traffic and a few "sporty moments".

Depends on your setting. For me stock is 3% optimistic, 3+1 was 9% optimistic and 3+2 was about 12% optimistic.
-

Ah OK, well I'm on 3+1 so over reading a bit higher than you. Any idea what the power output is at 3+2 btw?

Nope,
I think Andrew did most of his Dynos on the +1 setting. If I remember rightly, +2 didn't really up the power appreciably, but the profile of power development changed.

Can't complain at 50mpg from a 240bhp car can you?
-
Definitely this ^. I so badly want to get a tuning box lol. Something is holding me back but I don't know what ha.
-
I didn't like the way mine drove with a box on but I seem to be the only one :whistle: maybe I had a dodgy box or something.
-

Ha, indeed mate!
Definitely this ^. I so badly want to get a tuning box lol. Something is holding me back but I don't know what ha.
I was in the same boat, never got round to it (and had other things I could use the money for too), but it's an awesome upgrade. I introduced a friend to it last night, a few 2nd gear antics on some roundabouts (empty roads), it was probably the most fun I've had in the car to date.
I didn't like the way mine drove with a box on but I seem to be the only one :whistle: maybe I had a dodgy box or something.
What was it you didn't like mate? It's been very smooth for me, drives the same but just smoother and more ompf, only really used 3+1 so far (your box was probably pre-Trevor?).
Sorry for the off topic stuff, can reply to me on the DTUK thread if you like ;)
-
Mine was the pre Trevor box. It was fine apart from juddering in low gears but once it was up to speed it was fine. I'm in two minds if i should get another one as i still find the stock output enough and it's still plenty quick. Good thing with the box was the car seemed to have less regens.
-
Pretty chuffed with my MPG this month, particularly seeing as the majority of miles were urban.
(http://andrew-parker.com/golf-mpg.jpg)
-
Pretty chuffed with mine too. Not too shabby for a DSG equipped GTD. Coming back from Preston along the M6 at rush hour so speeds anywhere between 60-70mph. Driver profile "Individual" with engine set to normal. That range of 520 miles is with me already covering 126 miles so a theoretical range of 646 miles.

Mine's still crap, and has been since it went in for its first service last August when changes were made (which saw me get twice as many regens) - it has never been the same since. Had a very leisurely drive to Durham (24 miles each way) on uncluttered roads, about 1/4 of it on a 50mph average speed camera monitored stretch of the A194(M). 46mpg each way, and it was quite warm out.
Bring on the R with 28-30mpg. :grin:
-
Mine's very good at the moment on a couple of runs to the outskirts Manchester (120 miles each way, 95% motorway), according to the computer 59.6mpg... we'll see what it really was when I fill up but experience shows it'll be close to 58mpg with that reading. Average speed was > 60mph...

What changes were done during your service mate that made it less fuel efficient and cause more Regens?
My cars getting it's first service next month, hope mine doesn't suffer the same fate :rolleyes:

Wish I knew, but at least the driving mode amnesia sorted itself out. I do wonder whether the official fuel and MAF output readings logged by the ECU seemed unusually low because of what the car thought it needed (pre-tuning box signal modifications) and VW "corrected" the car.
-
Whats the maximum range these do from a tank? I've seen a few people have cracked the 500 mark but could you achieve say 550?
-
I got 66.7mpg yesterday from Sunderland to teesside park on the a19 in eco mode with the acc set to 58 and climate control set at 22. Set it to normal mode on the way back and just got 57mpg, must be all up hill from teesside haha
-
Whats the maximum range these do from a tank? I've seen a few people have cracked the 500 mark but could you achieve say 550?
It entirely depends on your fuel consumption :rolleyes: Effective range is about 11 (as 50 litres is about 11 gallons) times your fuel consumption, so at 60mpg... close to 660 miles would be achievable
-
Indeed, my best is 550 miles after a week of mostly motorway cruising and I get 500 more often than not.
With more town driving I will get closer to 450.
I might try and hit 600 now it's getting warmer!

Personal best is 572. Still aiming for 600.

Unless you're pressing into the "reserve" (that unknown amount below an indicated 0 miles), you're rarely going to get more than 10x your mpg rating e.g. 55mpg average = 550 miles. Te car will do a little more, but there's always that worry about running out.
572 miles is pretty impressive if you're not sitting at 60mph on a long motorway run. The best i've done on a constant 80mph in the middle of Summer and with the aircon on all the way is 57mpg between Newcastle and Leeds (105 miles), generally it;s 42mpg around the doors in Winter and 48mpg around the doors in Summer.
-
572 was with the fuel warning light on, and only a couple of miles to filling up again. I had a run up to Rowlands Gill and back on Saturday. ACC set around 68/70 going up and indicated mpg for the northbound journey was 57. Coming back, low 50's with ACC set somewhat higher.
-
Had a real good run in the GTD yesterday (first time in a long while), down to Lichfield. Took it stead on the M6 (65-70ish) and then 50mph through the road works (average speed cameras), then 60ish down the A50 and other A roads to Lichfield, and was pretty chuffed to see these figures on my return. This was from a cold start, on quite a busy M6.
Car set to individual mode on the driver profile select - which for me is Engine - Normal, DCC - Comfort, ACC - Sport
So 161mile round trip at an average speed of 48mph and it returned an indicated 64.5mpg (which knowing my computers accuracy) should work out at about 61-62mpg. Pretty chuffed with that on a DSG box. It had my theoretical indicated range as 659 miles which I've never had before (415 range plus 244 miles travelled).
Still not quite the 68.9mpg Extra Urban that VW quote (based upon a real 62mpg it's still 10% out), but pretty much in line with the advertised Combined figure of 60.1mpg for my model.

I've got a rental 1.6 TDI at the moment. On a 60-mile cross country run yesterday with 4 people and luggage achieved 64mpg. Not bad I thought but then I had a look at the official figures and saw that officially it should do 74mpg combined! So I think the rated Mk7 figures are totally unrealistic really :laugh:

It is because the consumption tests have a lot of standstill time in them and cars with stop start can easily manipulate their MPG figures.
I've noticed a big increase with the improvement in temps. I'm getting 55MPG regularly now (calculated, not indicated)
-
Agreed. I'm not complaining at the Mk7 economy as it's more than acceptable, but it's a shame the official figures are now meaningless. My Mk6 is rated at 53 and it always averages at least that.
-
The MPG is great TBH. I had a Leon FR PD170 with bluefin and daily got 45mpg from it and on a long run got 60MPG easily. Now had the MK7 GTD since May last year. Just back from a 5 thousand round mile trip to France (230 hours or driving!!) and reset everything before i went.
Average 52mpg, best 61mpg, and believe me i wasn't driving fast as nobody wants to attract Foreign police on their tail. Maximum per tank was around 490.
-
Okay so just hit my personal best to my normal trip to work this morning. The journey wasn't particularly different to any other Friday...
(http://i176.photobucket.com/albums/w198/Mohsin_Iqbal/Mobile%20Uploads/20150626_080501_zpslmuchjsl.jpg) (http://s176.photobucket.com/user/Mohsin_Iqbal/media/Mobile%20Uploads/20150626_080501_zpslmuchjsl.jpg.html)
Quite impressive and feels like the engine has really opened up compared to when I first got the car last April. Normally on this exact same journey I can get anywhere between approx. 50-60 mpg with 60 mpg on a good day. Never seen it this high before. Oh and this was the figure door to door.
-
Top effort that Mohsin. The 16.5 Celsius temp will of helped too.
-
Yep for sure when comparing to winter results. Comparing to similar temps from last year, this is a lot better.
If only this was a long term average! Haha.
Got my service due in a couple of weeks so I'm hoping oil change will improve the consumption a little.
-
55.9mpg on the first run into work this morning (47 miles mostly motorway). For a brand new car I'm happy with that and only a couple of mpg of my Mk6 indicated (140 TDI DSG), I suspect the Mk7 is more accurate :)
-
49.9mpg on 5 mile commute to work this morning 17c outside, would have been higher if there wasn't a van going around 30mph in a 40 for a couple of miles.
very impressed with this from a cold start.
-
Doing 30 in a 40 shouldnt effect your MPG really, quite the reverse really.
The only thing that badly effects it is stop start traffic.... rolling along at 30mph you should easily get 50mpg on a not cold day.

It depends what gear you are in as well. I was in 3rd but if i hit 32mph it tells me to go into 4th and at 41mph it says shift up to 5th. If you are in the suggested gear your rev counter will be sitting at approx 1200rpm and if you are in a lower gear it will be sitting around 1700rpm.
-
1200 miles in and averaging 46.7mpg. Thats 4mpg better than my 3 series which didn't have near as much power.
So far i am very happy with that

That's only about 16mpg more than my 3.0 straight six 315bhp!. :sad:

What did you expect?
I had a Golf Bluemotion 1.6 TDI as a loaner a little while back. In the several days I had the thing it reported 50mpg - whilst breathlessly trying to get up hills and generally being a gutless POS.
I'd say it was quite remarkable that something as powerful as 184PS was capable of easily cracking 50mpg whilst never being short on torque....and you 30mpg 3.0l six costs 1500 quid a year more to fuel for 20k and presumably about 400 quid in road tax.
If you are made of money fine I guess!
-
Drove up to Arran yesterday with 4 people and luggage (tight squeeze for the luggage) and just got 50mpg. Just had 4 new tyres replaced last Saturday and they are either losing pressure or aren't balanced properly as I was getting a vibration from under my seat. Even with car fully fully loaded it's still got loads of torque when needed. 50mpg isn't bad but thought I may have got more as wasn't hoofing it up. Pull up at ardrossan ferry terminal to find its doing a regen! 14°c yesterday when I checked the tyres and they were perfect. 10c this morning and they've lost an exact 1psi.

I drove down to Alton Towers and back when the car had only 150 miles on the clock, total of 550 miles. Boot was full because of all the stuff a 2 year old needs and got 51mpg. Last year I drove to York and back in my 3 series and got 60mpg but the car had 33000 on the clock.
-
Still finding mine pretty variable. 3000 miles in and I get anything between 47 - 56 mpg on the same daily journey! Its not bad as the reported figure seems pretty accurate unlike my old Mk6, but the annoyance is the limited tank range.
-
48-50 mpg for my daily commute of 14 miles each. 55-57 on a run kept within the speed limits. Over 80 and your mpg (46 -48) will suffer like all diesels :whistle:
Very happy great drive didn't expect to reach advertised mpg & if you did then you need to do proper research in future :rolleyes:
I drive in Normal mode
-
First tank down and 44mpg. Mainly using ACC motorway driving between 70-80
My commute of 2 miles each way doesnt help though but unfortunately i am not allowed a petrol car as my company vehicle...not that i really need a company car anymore :whistle:
Was a little shocked/suprised that the tank is only 50lts....my Seat Leon 2.0 CR was 55ltr so range seems limited. Just had to fill up after getting 420miles from a tank
-
Just past the 30,000 mile mark (30,314 at the last fill)...
Average across all driving 47.5 (using RoadTrip) but 48.08 in the last 12 months with a best tank of 54.13 and a worst tank of 31.41 ( :embarrassed:)...
I'm reasonably impressed...
-
I'm on 500 miles from my full tank. I usually only get 440 but I've been driving it very carefully.
-
Another 500 mile plus tank for me this month and ticked over 10000 miles. Had a little drive up the A697 towards Wooler, cruising at around 60mph and had the MPG up to well over 60mpg.
I'm also positive that the new Goodyear tyres I've had fitted have made a difference. Just seems like less effort is needed to improve the economy.

Got this this morning on the way to work

that is brilliant. I have only been doing my my 5 mile commute and back this month due to so clown being in charge but i am getting around 49mpg on the commutes.
-
I find the GTD so inconsistent with MPG.
I have a 3 mile stretch of dual carriageway road about a mile after leaving the house. Its usually really quiet in rush hour.
So sometimes I'll put my foot down if running late. The other times I'll drive very refrained yet there is no link to how my MPG is by the time I do the second leg (8 miles of slowish traffic) and by the time I get to work.
Sometimes its in the 40's others its in the 60's
-
I find it a little sad these cars are to be driven and enjoyed not poodled along to try & get unbelievable mpg :rolleyes:
Driven with fun in mind they still achieve mid 40's anyway :laugh: If people are so hooked up on mpg then perhaps a hybrid or electric car is the way forward :whistle:
-
Its called diversity. I've never before tried to see how much I could squeeze out a tank of fuel or indeed my best MPG. That style of driving isn't me at all. But I must admit it was a lot more relaxing than i thought it would be.
Over the last few months I've found the GTD drawing a lot of unwanted attention which I was just about to post on the Mk7 board.
-
Long time lurker here sorry, first time on a forum so this may be in the wrong section but... I noticed you said about the GTD getting unwanted attention, in what way? Only I have one due to me in a couple of weeks so I was curious to know.
-
I think I know what p3asa is referring too. Coming from a very plain looking 2.0 TDI Match to this, the way people perceive the car is a lot different...
Today was a good day for economy anyway, 55mpg on the way in and 53mpg coming back. Definitely seems to be improved as the mileage is getting higher (3700 in 7 weeks) and that's just driving it normally without consciously trying.
-
@j400uk thanks for clearing that up, I kind of thought he meant unwanted attention from the wrong sort of people, as im already a little weary because of some of the horror stories Ive read on other forums. Looking forward to it nevertheless and been on this forum just makes me realise ive made a great decision. Thanks again
-

I'm pretty sure everyone here is driving a GTD because they need a car that offers the right compromise between performance and economy, otherwise we'd all be driving GTIs or Rs. The major attraction of the GTD for me, and indeed why I bought one, is that it can sit on the motorway at 60mpg+, or provide decent thrills when driven enthusiastically. Not many cars can do that.

Average speed? Over what distance?
I'm sure it is possible... just not driving normally? :wink:
-
No not driving normally :grin:
Over 12 miles 60mph then down to 50mph due to traffic then 30mph for the last mile or so.
Always changing about 2k.
I certainly don't drive like that normally but wanted to see what I could get out a full tank of fuel as i usually only get around 440 miles. I managed just over 500 miles driving.

Agreed. I'm driving this because I do 25,000 miles a year meaning diesel is a necessity to keep fuel costs under control. When I was doing 5000 miles a year I had a GTI. If circumstances change again I'll get an R! Nothing in it between them price wise but big difference in running costs.
-
I'm coming up for 40k on the clock now. Average 50 - 53mpg without any effort in these 'summer' months. Have had the occasional 60+ but don't know how or why as driving style has never been different.
-
Almost managed 63mpg today! This was my first time actually trying for economy as I left work with only 35 miles showing remaining and a 43 mile journey to make. So AC off, Eco mode and staying in the slow lane resulted in this:
(http://i187.photobucket.com/albums/x267/J400uk/Capture_zpsy2kyt0tp.jpg)
Filled up and only got 48.5 litres in before it clicked off so could have kept going even further...
-
Do people have any preference for type of fuel? I never use supermarket stuff but I'm finding that Shell Regular diesel gets notably higher MPG than Esso diesel.
-
Only ever used shell or esso and find shell slightly better than esso. We have esso premium diesel in Sunderland but never used any.
-
I am going to give premium a shot next as prices are low just now. Regular is 106.9 & premium is 117.9
-
Slightly offtopic, but related to VAG TDI mpg.
As you might've seen in another thread, we've taken delivery of a new Audi A1 1.6TDI Sport. The missus is taking her driving test (at 38 years old) in a month's time after a 12 year break from trying.
So i've decided to give the 7R a rest and run in her new A1. I've done about 90 miles in it over 3 trips, getting a consistent 56mpg. I second guess the car's gear change suggestions - we seem to be on the same wavelength.
Took the missus out on the L plates today, she was driving up the north Sea coast from Tynemouth to Blyth and back.
The missus was almost always 1 gear lower than I would've been in (sitting at 20mph in 2nd, 30mph in 3rd, not hitting 4th unless doing 45mph), and on that 18 mile round trip I was astounded to see the car had given 65mpg indicated. Driving the car in a way that would seem to be uneconomical has given the best result. :undecided:
Diehammer- unless you want your injection system cleaning, I would avoid Shell V-power diesel - it is less calorific than regular diesel, so will give you fewer mpg.
My GTD ran best on BP and Esso. A string of pre EU6 TDIs owned always had a preference for Shell, not the 7GTD in my experience.
-
I don't think I'd be babying the car like that in its first few miles by changing up when the car was telling me to as I always think it tells you to change far too early and almost labouring the car.
-

I was giving it a bit of welly when getting up to my desired speed, but once there i'm quite economical. Maybe i'll have it hang on to the gears a little longer when going around the 20/30/40 roads. Most of my driving was 50-80mph, so makes sense to be sat in 5th at 80.
-
There is only 1 shell garage in a radius of 10 miles so that won't be an issue monkeyhanger. I would most likely use esso as BP is really expensive at the 2 garages here and one is right across from Grangemouth Refinery.
-
First ever tankful brim to brim today.Horrified to see my GTD had done only 44.3 mpg.Computer was saying 47mpg so i knew it was going to be low.
-
Do you mean the car said 47mpg but your actual fuel usage calculation based on delivered volume was 44.3?
Doesn't surprise me to be honest, especially if you have had a few cold morning commutes. Starting from sub ten degrees and you will see fuel usage increase.
Equally, my trip home last night gave me 57.6mpg - a new home commute record for me :) It was 13.5 Celsius and the journey was about 40 miles.
Enjoy it while we can though, the super nasty winter sludge is coming... 6 months of poor economy.
-
My trip is stating 46mpg long term so 2400 miles from brand new....most journeys are sub 5miles at the moment 2 miles to and 2 miles from etc so im quite happy with it
Longer runs im seeing 50mpg+
-
This week I've got above 50mpg every day, even saw 56 today. I haven't been driving it differently and still using Shell fuel so not sure what's changed from last week when it was sub 50! Just over 8000 miles on the clock now so well run in, 4 months old.

Yes the car said 47.I zeroed the speedo when i filled up first time.Then after 435 miles i filled up (took about 45 ltrs).I've been running it in gently as per the handbook so i can only imagine how lower it will go once i start going faster.The 44 was with a mix of heavy traffic,A and B roads,dual carraigeways.Daily round trip of about 34 miles.
I presume the fuel economy might get a bit better once it's got a few miles under it's belt.
I know that manufacturers are economical with the truth about real world mpg.But 44mpg is really just criminal.
I'm going to run a fuel log for at least a year.See how the weather/seasons and mileage changes the mpg.Might even use the eco button if i get really desperate. :grin:
-
fuelly.com is good for recording the fuel used.
-
The mpg does increase when its loosened up a bit, maybe as much as 25%.
Remember whilst temperature, speed and all sorts make up your fuel usage, the variable we all can't describe when talking about this is the terrain over which we drive.
Any Dutch drivers will be creaming us all :)
-

If you're expecting that to happen, you'll be disappointed. You get appreciable gains in output around 640 miles (approximately 1000km), there must be some kind of "running in" mode limiting output - i've experienced it in my 2011 Scirocco 170TDI, my 2013 MK7 GTD, my 2015 Golf R and my wife's 2015 Audi A1 1.6TDI. Had 7 VW TDIs from new and never seen appreciable gains in mpg, not 5%, let alone 25%.
I'm sure some confuse the summer gains (can be as much as 10% when we get some warm and moist air in the TDI's lungs) for "running in" gains and then see their gain disappear again when winter comes around next time. Or they're trying harder to get that mpg by driving like a nun and proclaiming they have found those extra mpg from running in.
-
My overall MPG in my GTD is only 41.4mpg!
I can get over 50mpg on the motorway, but that's usually only about once a week, most of the time I'm just commuting to work which is only 2 miles lol
-
fuelly.com is good for recording the fuel used.
I had a look at that site.But it was a bit too American for me.I had a look at the Honest John site 'real mpg' for GTD's.Seems 47mpg (average) is the norm.He also recommends BP Ultimate for diesels.Might give that a try sometime.
I love the car though.You can tell there's a lot of thought been put into the engineering,gadgets and build quality.So i'm not going to become fixated on the mpg.It is my tartan trimmed tank!.
-
Filled up with Esso Super Diesel today, been using standard diesel from Tesco previously. It might be in my head but the car seems to be far smoother already. Costs 115.9 per litre v standard diesel at 106.9 but I want to see if it has an effect on mpg. I was am sitting at 46mpg after 2700 miles.
-
Filled up again this morning, 0 miles left in the tank according to the computer. couldnt get anymore than 49 litres in the tank.
Managed to get 420 miles with the Super Diesel but temperatures have been down quite a bit.

The 0 miles to go indicator must come on with over a litre of fuel left. You need to drive it more if you want to get 50 litres in.
The most I've had in mine so far is 51.531 litres according to fuelly

Bloody hell P3asa, you must be "enjoying" your GTD to only average 35mpg :-)

EDIT: Just had another look and yeah it says 35.3mpg which is bizarre as the vast majority of fuel-ups are at least 40mpg with the lowest being 37mpg. Strange.

Not seen this thread updated for a while, and thought I'd join in.
Got my GTD at end of January (pre-reg), and have done about 3K since then, which is a lot more than I normally do in that amount of time. Was initially a bit disappointed with MPG, but as the miles have gone on it and the temps are up a bit now it seems to have improved by quite a bit. Had a new record high on the way to work today...
(https://farm2.staticflickr.com/1719/25938792342_57347076d2_b.jpg) (https://flic.kr/p/Fw86gC)
Having said that I didn't get to press the throttle that much today! My journey is about 80% motorway, with most of that limited to 50mph with the cameras on the M74 at the moment.
Long term average is sitting about 44mpg. Since refuelling it's 48 so am having a good week at the moment!
However, so long as I can get above 45 on average I will be happy, as I do like to "enjoy" the performance at most opportunities I get, especially going down the on ramp to the motorway :laugh:
-
Diesels are very sensitive to ambient temp and humidity. In the depths of Winter, on a 10 mile journey, you'll be lucky to crack 40mph unless you drive like a nun.
In the height of Summer, you can cruise on the motorway at 80mph with the aircon on and see 58mpg (i'd expect 63mpg if you're willing to religiously stick to 70mph).
-
Hi.
I have a 2013 GTD 5dr and I can't get my average MPG above 40mpg!!! And that is driving it very sensibly.
I once got 50mpg on a 100mile trip sticking to 65mph.
Does anyone have any recommendations on what could be wrong with the car?
A lot of people on here are getting high 50s or 60s on a run. I'd be happy with mid to late 40's average.
My car has 30k on the clock.

What is your commute like? Distance etc? The GTD takes 8-10 miles to warm up. If you are doing a few miles to work each day and the car doesn't get a chance to warm up then you'll be lucky to hit 40mpg. If you don't give the car a chance to clear out the DPF via regen via a decent run it will be choked all the time. With a clear DPF, the car should average high 50s in the Summer on a long motorway run when maintaining 75-80mph.
A 100 mile trip sticking to 65mpg should yield over 60mpg. My GTD once did 58mpg going from Newcastle to Leeds and back in the middle of Summer with the aircon on all the way, maintaining 80mph for most of the journey.
Is it using any oil (or have you not had it long enough to know if it needs topping up between services?)? Oil consumption is characteristic of a poor run in when new, and poor mpg usually follows.
-
My commute is 20 miles each way and I stick to 65mph.
I drove from Middlesbrough to Leeds last week and it only got up to 47mpg sticking to 70mph.
I have had the car for around 6 months and have just had the oil changed a month ago, fuel consumption is exactly the same.
I wonder if it could be something else, fuel filter perhaps?

20 miles each way on your commute - your DPF should be as clean as a whistle with normal driving enough to provide passive DPF regens. Your car definitely doesn't seem right. I drove my GTD a lot harder (higher average cruising speed than you seem to be doing and got far better mpg. Is it still under warranty (just)? Could be a fuel filter or stuck EGR valve.
Is your car manual or diesel? Manuals are around 10% more frugal like-for-like in my experience. Might be worth getting your brakes checked for excessive wear too.
I have a 20 mile commute and this week, i'm driving an Audi A3 150TDI Saloon courtesy car (and driving it very hard), still managing 60mpg to work and 55mpg home (roads a bit busier going home) - i'd expect a GTD to be 10% thirstier than this car.
Maybe try a fuel additive for cleaning the fuel system, like Wynns Xtreme diesel system clean?

Woody, not being funny, but have you learnt to take your foot completely off of the gas when you don't need it? That's probably the biggest killer on fuel over motorway distance.
Or alternatively, do you put your ACC on when you are on the motorway? 20 miles at 65mph on ACC providing the temperature is above about 10 degrees C and assuming that its not a climb from the foothills of the Himalayas to Everest....

My commute is 20 miles each way and I stick to 65mph.
I drove from Middlesbrough to Leeds last week and it only got up to 47mpg sticking to 70mph.
I have had the car for around 6 months and have just had the oil changed a month ago, fuel consumption is exactly the same.
I wonder if it could be something else, fuel filter perhaps?

My car is out of warranty now and is a DSG so I do expect slightly lower mpg than a manual.
When I first got the car I ran a tin of BG244 thru the system and on each fill up I use a shot of millers.

Yes I do take my foot off and use the engine braking rather than using the brakes.
I normally use the ACC on 65 and have also tried the journey without ACC and both return around the same mpg.
I owned a 3.0TDI A4 before this and that was returning 42mpg on the commute (and that was driving anywhere between 65 and 80). I have been driving like a nun in the GTD and can only just about manage that.
-
Is that maybe 18 ish miles at 65mph with a couple each end of winding roads?
It really shouldn't be as low as you say. I'm sure if I knocked mine back to 65mph I'd get more... let me try tonight. My regular run is about 20 miles of mainly dual carriageway and motorway without jams.
Have you checked your tyre pressures btw? Make sure you haven't got them set for the wrong load.
Not got roofbars on? Windows or sunroof open?

Yes it's around 16 miles at 65mph and 4 miles urban, no jams.
I'm running 19s and have 38psi in, no roofbars, windows open etc.
Very strange...
-
OK, so I have a five door manual 14 plate gtd with 18's on it and no passengers or junk in the car.
Temp was 16 degrees Celsius. Car started after eight hours in work car park.
21 miles covered. 3 of normal roads than sixteen of dual carriage way and motorway with acc set to 66mph. No traffic. Then two miles of normal roads.
56.4mpg. That's a bit better than normal, probably because I normally do 70mph on acc.
-
Ambient temp and humidity is a significant factor for TDIs.
Yesterday in the coutesy A3 150TDI I was getting 60mpg to work with an ambient temp of 17C. Today, the coldest morning in ages it was 9C and I got 52mpg driving it the same way. I wish Audi would get the wife's A1 fixed so that I can have my R back off the wife - she's started using Yankee Candle sticks in the air vents!

Wow, that is good. It'd be pleased with that. Mine has 19s and a DSG so I'd expect slightly less. Would love to break the 50mpg mark on a 20 miles route.

OK so there is the answer, I'd have guessed at 5mpg difference for both dsg and nineteens so that's about right.
-
I meant to say, that's with the mode set to "normal". I think on dsg if you use eco mode it does something about coasting and is earlier shifting? (makes little difference in manual)
-

Do 19s really make such a negative difference? I'm running my R on 19" Prets with sticky Michelin PSS tyres, and they're 10mm wider than the GTD/GTI option Santiagos. Running in Sport mode on my 20 mile each way clear commute and i'm seeing about 35mpg.
I do notice a significant difference running the aircon with or without recirculation - I leave it at 17C with the recirc on and it hardly makes a difference to mpg. Put it in LO without recirc and I drop at least 3mpg. The GTD used to have similar mpg penalties with aircon running in its least economic mode.
-
Well, it definitely makes a difference to the CO2 figures, which almost certainly is a MPG impact.

Just did a 500+ mile round trip from Cheshire to Essex over the last weekend for a wedding. 4 up in the car with a full boot. Hold ups at Leicester (M1) and M25 (both ways), and mostly sat on ACC at 70mph on the motorway (except the large 50mph zones on the M6 in Cheshire and the M1 near Luton) but overall got this (see below).
Bear in mind that the car has only 3000 miles on it and it is DSG not manual and I am also running the 19" Santiagos. Can't complain really. Filled it up this morning and manually calculated it at a true 54.77 (43.24 litres - second click @ £1.109 per litre)

as an aside, it's interesting that the mobile phone camera captured the infrared sensors of the motion sensor bar on the head unit (never noticed that before :grin:) (https://flic.kr/p/LEvTiX)
-
That is impressive. Very impressive.
Mind you, the longer the trip, the more likely you are to get good MPG.
Biggest killer is getting the thing up to an efficient temperature.
-
Travelled down from North West to Kent Tues, but filled up at Shell Crewe J16, M6 on the way down.
My 'long term' is 39.7 mpg over about 2k miles.

^ That is abysmal for such a long journey in a GTD. Whag was your cruising speed and was there much traffic?

Lets just say I wasn't hanging about :whistle:
Had a run in with a 15 plate Focus ST on the Autobahn, I mean M6 Toll, GTD come out top...
-
Was thinking that myself - must have been caning it at around 90mph or had a horrendous journey to get that sort of figure as an average ?
If you look a couple of posts above your, I did a similar journey last weekend (from Cheshire to Essex), in my 19" Santiago and DSG equipped GTD (with 4 adults up and luggage) and averaged 55mpg when the cruise was set at 70mph - methinks you have been enjoying yourself :grin:
-
I could never manage to get above 45 on a run in my gtd and that was driving very sensibly. Did show 75mpg once coming down hill on the isle of Skye haha

There was quite a few 50mph zones, in these I set my ACC to 55mph (which in reality is about 51/52?) I find I still get cars flying past me in these average speed zones - how do they get away with it?
But yes I like to enjoy the GTD :roll eyes: Really actually must try sometime to get a good mpg, I just get baited too many times by the likes of 118d's.. still think the TR attracts too much unwanted attention.

Glad you're enjoying it - I thought you might've been one of the poor unfortunates that can't crack 50mpg driving like a nun. Is yours boxed/chipped to be able to spank an ST? Mine with a DTUK box comfortably outdid older (225ps) STs, and on par with the newer (250ps) ones mid-range.

No its standard, but will put a DTUK on it soon. The guy in the ST looked shocked as we were both more or less on par from a standstill then I pulled passed him at a certain speed.. he slowed down and backed off after that. But like any car, he might of not been driving it to its full potential.

Can anyone tell me how optimistic the MFD is when using the DTUK box?
I read it somewhere in this thread but can't find it now!

Depends on the setting, but on old box 4+1 and new box 2+1 setting, mine was about 6% over optimistic vs stock 2% optimistic. The massively over-fuelling TDI-Tuning box I started with was about 13% optimistic.

Thanks for that. I have mine set at 2+1 at the moment and am very impressed. Was this your favourite setting?

On the new box (there was an old box that I had bought as an early adopter and Andrew at DTUK let me trial a new one when he was tweaking the developed settings) 2+1 was my favourite setting - the most smooth power delivery with no overfuelling. My Dad inherited my box for his GTD when I got my R and is still happy with it on 2+1.

Nice steady run today on the way back from Inverness to Aberdeen (just over 100 miles)...speed hindered by the number of lorries and buses on road which is mostly non-dualled, but the traffic was flowing well
MPG was reading 67/68 before getting stuck in queuing traffic near the city brought it back down a bit to this figure

Hi phope. Good figures.
Is your GTD standard and a manual?

Manual :smiley:
