Just before xmas I bought a '56 A3 2.0TDi 170Bhp Quattro S-line, loving it . What I would like to know is what sort of mpg are people getting from there Quattro's ? I normally drive on A-Roads & through towns/villages & I'm seeing approx 38mpg on the 2nd trip computer & approx 41mpg on a trip to work (32mls). I have added some injector cleaner to the last two tank fulls of fuel, just to see if it will improve the mpg & it looks like it might have but only by about 1 or 2mpg . Before you ask I have looked through the old posts , Cheers.
