mk6 gtd vs mk4 130

Right I know this is a stupid question but why why why is my gtd using more fuel going at same speed as mk4 (remapped)? Both 70mph to rugby yesterday gtd murdered fuel and mk4 barely used a needle???

Ive got a leon with the same engine as your mk4 so know what they are like.
Reading many threads on the GTD I would expect it to be just about as good on fuel on a long journey but they don't seem as good on short trips.

West bromwich to rugby and gtd drank!  Even on a full tank on mk4 from west brom to london and back didnt really use that much! Nuts

At 70mph constant speed over 100miles+ (i.e. constant motorway), I would expect the GTD to return 60mpg (displayed). - Air Con off.

Just because the needle on the gauge doesn't move, doesn't mean it's not using any fuel. Fill both tanks, do identical journeys then fill them again to see how much fuel each has actually used.

It can also be down to the driver. I can get 55mpg knocking about in my Passat CR140. My mate has a Skoda Superb with the same engine and only gets 42mpg. He wouldn't have it that it was his driving, so one day we swapped cars and did the same 80 mile journey. At the end I had averaged 62mpg in his car and he only managed  48mpg in mine.

But it was me that drove them both in the same day...

I'd echo what dubber says about not relying on the needle to measure true fuel consumption.  I had a courtesy car last year and the needle barely moved over the course of a week, then suddenly dropped to nearly empty.  After filling up the tank, the needle stayed on empty for miles before gradually inching upwards.  Couldn't wait to hand the thing back.

Because one is a 2.0tdi CR with DPF and the other is a 1.9tdi PD with no frills 

The PD motor in all guises whether remapped or not is very well known for its effortless economy, my remapped PD130 Bora was much more economical than the 2.0tdi Audi A3 that followed..

Agree with that

I got the PD170 and until that was mapped and its DPF removed it would struggle to get better MPG than my old 130. On the drive home after I bought I was almost thinking 'what have I done' lol

But then its such a better car in other ways.....

the mpg from my mk5 1.9 mapped to 150 is around 38mpg in town and 45-50 on the motorway, my gtd gives me pretty much exactly the same, so running costs aren't too bad, I also find driving faster in the gtd will lose you less mpg than the older PD with their older turbos!
