Hi I am in the process of replacing my 04 A3 2.0TDi. I have only had it six months but want a newer car. My question is what A3's have turbo problems? Is the 170 completly fine? Is it only the pre facelift 140's which have the problems? If I got a 56 plate 140 quattro, will the turbo need doing at 60-80K? Any andvice would be much apriciated.
