Hi, iv got a 2004 gt tdi 140ps and im averaging about 27 mpg. I am doing alot of 40mph driving so dont expect it to be amazing but i would have thought it would average about 40mpg with the kind of driving i have been doing. Apart from a good service of the engine,remap, driving slower lol is there anything else i can do to improve mpg? Is there any other parts of the engine which get clogged up in sh!te and could do with a clean? I mean the tyre pressures are ok im up at about 32psi all round?
