Hi all. Thinking of buying a used A6 but i have heard some horror stories about the 2.0 tdi engine. Is it true that the oil pump is a week point on these engines and if so, what do i need to look for? It looks as if this car has been well looked after and serviced regularly but i'm still abit worried that i might end up buying a car that is going to go wrong on me. Any advice would be more than welcome.
