Anyone who can offer any help it would be much appreciated, as my searches havent really found me the answers I'm looking for.
Basically I'm looking at buying a VAG Tdi car for commuting, be it A3, A4, Golf or Leon I am not sure on that side of it yet, but I need some advice on which engine to go for? I had heard there is one type of engine which is stronger and more reliable than the others, and I need to understand a little better the benefits of whichever engine this is. I have read about the common rail engines, being newer technology as opposed to previous older direct injectoion engines, but not being as reliable... Is this the case?
Does anyone have any recommendations regarding which car to go for? I'm not really bothered about having the most powerful version of the engine, just don't want a pathetically slow 90bhp model.
