Hi Just bought a 1.8T Quattro Sport (180bhp) and i am not sure if it going properly. On a gentle 30 mile drive to work i am only getting 33mpg. My previous Mk3 Golf GTI 16v could get nearly 40mpg on the same trip. I have heard of the Diverter valve and Air Mass meters being a problem, how can i tell? Or is it ok and this is the best economy i can expect? Dougie.
