Hi, first post and need some advice fairly quickly please. Have the chance to buy an '02 plate A8 4.2 Quattro Sport Auto with FASH .Seems to drive very smoothly.Any known weak points? Only thing I noticed was it didn't seem to kick me in the back when pulling away from rest.I've been driving a Volvo T5 for a while so that might explain it. I've seen some 4.2's described as 40 valve, are they all 40v from 02 plate? Any advice would be much appreciated!
