I recently went to look at an a6 which had had a new engine fitted it was a 2litre tdi 2006 , the guy told me this was because the engine blew because of a well known fault with the standard oil pump, the new engine had a modified oil pump fitted, I have never heard of this as i am still looking to buy an a6, is this true or was he telling me a load of c**p. will look forward to your replies.
