What could be wrong with my car? MPG related.
I've got a 05 plate Audi A4 Avant, 2.0 TDI 140 bhp remapped to 195bhp by AMD (lakeside)
I yesterday, took the car for a 120 mile trip to basildon and stanstead, with very little town driving. The entire journey on the A406, A13 and M11 i was doing 55/60 mph, at one point doing 100 for LESS than ONE minute and another point doing 50mph for a few minutes behind a restricted lorry.
I brimmed the tank before hand and after and calculated 42mpg. this is using BP ULTIMATE Diesel.
Somethings definately up! I should be getting 55+ at those speeds at the least.
What could i do to improve my mpg? Service is due in 8,000 miles. It had a flat panel air filter put on during the remap and its ridden on 18'' inch wheels.
Tyre pressure is good. I was using the air con slightly but at 22 degrees so wasnt really working it hard.
I go very easy with the throttle, never over 1/3 and always change up at 2,000 rpm.
any tips or suggestions as to what is zapping my fuel would be great?!
thanks in advance,
Also, slightly off topic, but anyone with Vag Com around East London? (Ilford/Wanstead/Walthamstow etc)
