MK7 GTD - Real Life MPG

[Gordor]

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'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 - 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 

Btw...really glad you are enjoying.

[noobmonkey]

hehe - still very much enjoying it :0 - wishing payday came round sooner, so i could get some more fuel in it hehe

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 - well... it might be me, only heard a regen once.... assuming non-audible once driving, only visible on mpg?

[Gordor]

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)

It was reading 61.7mpg at one point, but I then hit 5 sets of traffic lights in a row 

[noobmonkey]

Now that is impressive!!!

I managed 12.2mpg on way way to work this morning! Hell yeah!!  
I have noticed, not having the stop start active (on small trips) really does damage any mpg

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 (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)  . 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 ?
