i have joined this site because i heard i could get some good info..... i have an a3 1.8t thats a 1999 with its fair share of miles!lol
iv just solved a problem with the boost because the wires had been pulled off the top of it ( aint a clue how it happend).but now i get a mad kind of grinding or wearing noise when the turbo kicks in at abt 2.1/2 thousand revs.
its been remaped to 195bhp and goes like stink..... thers no boost problem of what i know of anymore but that noise is doing my head in!!!!
any suggestions of what the problem could be would be much appreciated!!!!!
