Hi all, I'm selling my A3 1.8T for an A4 Avant ready for the new baby. I really would like an 1.9 TDi (130) or 2.5 TDi in automatic or semi-automatic, but I'm finding them few and far between for my budget of upto £10k <80k miles on a 52/53 plate, with all the features that I require. Going through Autotrader I saw a lot of 2.0 FSI models with multitronic. The performance figures don't look too bad on paper, but how does this model perform in reality? Having owned a 1.8T and driven a 1.9TDi, I'm a bit cautious about going for a non-turbo car now. Is the acceleration sluggish? Are there any issues with these engines? Which is the best FSI engine? What is the main advantage of FSI anyway? One last question, according to Parker's Guide, rear electric windows on an A4 are only available on V6 models - is this true?
