Hi All,
I have been a passive observer of this forum for years having been an early adopter of the Mk 6 GTD and have just taken delivery of my Mk 7 GTD last week.
The car is everything I hoped for and I have loved driving every one of the 700 odd miles so far. :grin:
Just a quick question though. What is the fuel tank capacity supposed to be? The manual says 50l, the VW website says 50l and everywhere else I read does too. However, I have had to fill it up from pretty much empty twice now, and am only getting a shade over 40l in it! This doesn't seem right and I have tried filling it further once the actual pump clicks off, but only manage a tiny bit more.
Any clarification for those who already have their GTDs would be gratefully recieved. Does it only have a 40l tank or is something amiss here??
-
50l tank, mine allows me to get 46l in when if says 0 mile range left, so it must have about 4l reserve. I only fill to the first click.
-
Most I've ever been able to get in is about 43 litres (don't run the clock down to 0 miles). Whilst it obviously doesn't give you the range of the previous generation cars (MK6, Scirocco etc.), at least it cost much less to fill up each time (even if you do have to fill more often) :grin:
-
Strange that is is a 50l tank but we can only get 43 or so litres in it!

I’m sure you could get 50l in if you ran it dry, but VW want to give you the option of not coming to a spluttering stop when you hit 0 miles on the MFD. Think if it as a 6 or 7l reserve.
The 50l tank was a reduction from 55l on previous gen because we were supposed to be getting so many more mpg based on the cycle tests.
My Scirocco had 55l (12.0 Gallons) tank and was supposed to be 53.7mpg (combined), giving a range of 644 miles. Reality was I got about 530 miles from a tank to the reserve (10.5 Gallons used/50.5mpg).
GTD has a 50l tank (10.9 Gallons) and is supposed to be 67.3mpg (combined), giving a range of 733 miles. Reality is that I get about 430 miles from a tank to the reserve (9.8 Gallons used/43.9mpg).
I would take that reduction in tank size as faith that VW think we should be getting 60mpg from our GTDs so as not to reduce the range on a full tank. Reality is that like for like, the fuel used to take me 530 miles on my Scirocco, would only take me 461 miles (10.5 gallons @ 43.9mpg) driving the same way. That’s progress for you.
-
Rather noobish assumption here, but 5l less would also be a weight reduction not accounted for? (What i mean is, the new GTD is already lighter, so this should make it even less heavy on a full load?)
-
I will fill it up next time when it is as empty as I dare to try and get another litre or two in it.
My economy is improving but still lower then I had expected / hoped / been led to believe. It is showing 40.1mpg since new, but 45.2mpg since last fill.
Perhaps these really do improve as the engine runs in, but still a long way off what we were "sold"!
I won't really be happy until it is consistently in the 50s.
I do a lot of mileage (2500 - 3000 miles per month) so i will report back on how this progresses. I will also do some long runs on eco to see how that affects things.

They probably did take it into account on weight reductions as 5l of fuel weighs about 4kg, the thinner and stiffer bodywork shaved 26kg. That was pretty much it for the higher output Holds. The sub 120ps models lost a lot of weight when losing the multilink rear suspension that by/gfs/gti and some se models retained. Weight of car in use for stats is based on fuel tank being 90% full.

Can you fill the expansion tank on it?

I read in the early launch material, issued at the dealer sessions in Spain, that the fuel tank capacity had been reduced to help in production something to do with the Torsion beam suspension on the ' lesser'
models.

Expansion tank?
-
There is no “expansion tank” as such. The MFD will claim that the tank is empty when there is around 6 to 7 litres left in it (43-44 litres consumed from full). The filler neck might allow for a little more fuel, but you run the risk of a bit of fuel running out through it when the tank is that full.
-
Managed to squeeze 47 litres in the other day with indicated range just having reached 0 miles.
-
I managed to get 46 litres in it last week and it was indicating I had 10 miles left to empty. Do wonder if the misfuelling system is preventing the tank filling as far as it normally would.
I never could get much more than 50 litres in my MK6 though.
-
Once the gauge gets in to the 'red zone', does it tend to fly race to the bottom like my current Mk6?!
-
I managed to get 53 litres into the mk6 GTD once. :cool:
-

That’s because it has a 55L tank.

I know someone who managed to get 20 gallons into a Triumph Dolomite once. The previous owner had nicked the level gauge so he ended up filling the boot as well :grin:

I have now had my car into the garage to have them check it over due to my claims of poor mpg.
I can get just short of 50mpg on a run driving it like a nun and long term it is showing just over 41mpg.
I have had the car for 4500 miles and have seen no running in gains worth speaking about.
In summary the GTD is a sub 50mpg car if driven sensibly! Probably lower mid 40s if driven a bit more enthusiastically.
Very poor compared to the Mk6 economy

That's considerably worse than I've been getting (a manual) since the start. With less than 3000 miles on my long term average has always been 50+ (even allowing for computer / mileometer optimism which amounts to less than 2mpg).
Did the garage have anything constructive to say? Any assertion that it's okay surely must be bullsh!t when there are others who are consistently getting a lot better. I run everything set to Sport mode, except ADC and A/C which are on Eco, if that's any help.

Not really, they just claimed they could not find any fault logged with the car. I didnt expect them to.
I have a manual as well and my testing route is 140 miles between Aberdeen and Glasgow, apart from a few miles at the start and a few miles going through Dundee in the middle it is consistently dual carriage way. I set the cruise to 70 or 75 and just leave it at that.
I do use the heated seats etc from time to time but I generally drive with just myself and one bag in the boot.
I really don't thrash it at all - quite the opposite, I have been trying everything I can to get 50+ mpg on that run.
-
There have been plenty of people getting 40mpg ave, 45mpg ave and 50+mpg ave. People's driving styles and commutes are different. I have found with mine that with journeys under 15 miles, the mpg suffers.
If I were to do a 15 mile commute, I would see 50mpg with my driving style, 12 mile commute (my actual) is about 46mpg with no regens and 41mpg when it is regenning (44mpg total combined). I would expect a 10 mile commute would see me dip to 40mpg average and more regens than I currently get.
One thing for sure with the GTD is that 55mpg + is extraordinary for the average jouney. The official figures are fantasy, inflated by 20% over the previous generation because the testing regime has changed, not because VAG engines have come on in leaps and bounds. Every other marque out there (Ford/Mazda/Vauxhall/BMW etc) has also seen 20% increases in their published economy over the last 12 months or so on new models - that is no coincidence or simultaneous engineering improvement.

Nowhere did I ever read that the testing regime had changed. Surely if they are advertising cars with these fuel economy claims as a "comparison" they surely also have a responsibility to clearly point out that the goal posts have changed... Else there is no comparison.
It would appear that most consumers trust these figures and all apart from those that have done their own research realise the significance...
Otherwise they are just meaningless numbers...
Im going to be taking it up with VW.
-
The inclusion of stop-start plays a massive part getting better results in the current EU tests with 24% of the cycle at a standstill. A previous gen car with no stop-start that spends 24% of an 11 minute testing cycle idling is going to spend a lot more fuel in the test cycle than one with stop-start and switches off at standstill. In the real world, who spends 24% of their commute at a standstill? If you have very little stop time on your journey then you will not realise the "benefit" of stop-start tech and difference between MK6 GTD and MK7 GTD economy will be marginal.
-
Probably mentioned a few times in here, but got the 40miles left warning this morning, and filled up to the brim. Managed to fit 40.5 Litres in, so it must have quite a bit left in it to run when it gets to 0!! :P
-

I have virtually no start stop time on an 140mile journey I do between Aberdeen and Glasgow every few weeks. Cruising about 70-75 mph.
I still cant reach 50mpg whilst Mk6 owners are claiming an easy 55mpg+ for this type of journey.
You are correct, the start stop should show little difference in real driving figures, perhaps in the tests.
In real life the Mk7 seems a good 10% worse than the MK6 for 95% of drivers who dont drive on a rolling road. That is the bit I cant get my head round....
-
mike_f: A large part of that 10% could be down to Bridgestones (if you have them) with their very poor rolling resistance vs something like Pirelli P7s commonly fitted to the Scirocco. The Scirocco should be a little more aerodynamic than the Golf too.
I'm shocked though that you cannot crack 50mpg on a 140 mile trip cruising at 70-75mph. I can do 37 miles down to Hartlepool cruising at 80mph and see 51mpg. It's almost all dual carriageway with a couple of miles at 30-40mph at the end of the trip.
-
Another thing to remember is that the average mpg reading seems to be a lot more accurate on the mk7. Weren't the old models about 10% out?
-
I just put 47 litres in after driving ten miles beyond zero!
-
I put 52.74 liters in mine yesterday, driven 10 miles after it went to 0 MTE.
Wanted to see how far I could go - 713mi in 19h10' @ 37mph avg. yielding a neat 64.9mpg according to car :whistle:
-
How is that possible when the tank is 50 litres capacity?
-
Because the filler pipe will hold another 2l?
-
It has a nominal capacity of 50l, plus expansion tank plus filler neck. You could probably get 55 liters in there if you have enough patience and you're going to empty it fast again.

From my experience of driving VAG cars they have a fuel reserve. In my last 2 diesel Golfs I would get a warning 50 miles remaining. However, IIRC the fuel reserve was 8L and both cars did roughly 10 miles for every litre = 80miles on reserve. On several occasions I tested this theory and drove an extra 30miles after the car said 0 miles remaining. Though one time I did manage to put 57litres into my old 55L tank :shocked:
I have never managed to put 50L into our A3 even when it said 0 miles remaining. The manual says it has a 7L reserve and the warning comes on at 50 miles remaining. It also does around 10 miles to a litre. So it should do another 20 miles past 0 miles remaining.
When you first get a warning on the Mk7 GTD does it say 35 miles remaining (like my GTI) or 50 miles remaining (like my previous MK6 GTD)?
I have twice managed to put nearly 53L into my GTI PP. The car had just said 0 miles remaining. :shocked: So either I have no extra fuel reserve past 0 and was running on fumes with a 50L tank. Or my car has a 55L tank the same as the Golf R has.
I would just have to drive 10 miles after the car said 0 remaining. Unfortunately, it is bad to allow a modern engine run out of fuel. So I'm not going to risk it with this car.
-
I'm off on a road trip tomorrow so just topped up the tank, had 115 miles left in it, cost 50 quid to fill it, and now it shows that I have 390 miles of range WTF.
-
Did you reset everything?
-
No, but the range resets itself when you fuel up.
-
Mine normally shows just over 500 after I fill it to the brim. My real life MPG is 48.

That's what I was expecting.
-
The range looks at your current mpg so if you've been hooning around before filling up and it says 15mpg that's what it'll work your miles to refill on. Try resetting your current readouts and check what the predicted miles is then.

Cheers. I'll try that.
