MK7 GTD - Real Life MPG

[monkeyhanger]

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...

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 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   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

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.
