Im sticking the Type r on autotrader next week once the front engine mounts done, and i have seen a lovely A3 2.0 170 Quattro S Line on an 07 plate with nice optional extras. Anyway im just curious as to how much fuel i will save. Currently doing £200 a month in the Honda barely using it i decided i need a diesel. So those of you who have them what are your realistic mpg figures and how much does it cost to fill the tank? How much more would you save (fuel wise) getting the FWD instead of the AWD or is there not much in it? Also a few tips to look out for when buying one would be great as-well, do they have any common faults i should look out for? Its done nearly 80k miles.
