I have an '05 A4 2.0, and the engine appears to be idling very loudly, almost as if its a rattling sound. I think this noise has been going since I have owned the vehicle, but always thought it was the 4 cylinder engine. Someone mentioned it to me the other day that is was very loud, and it made me think that maybe its not normal. Is this normal on the 2.0 A4?
Thanks,
David
This is not normal the FSI engine does run louder then normal last year mine became even louder and developed a rough idle enough where it shakes then took my car to the dealer they pre formed a fuel pressure switch recall and also secondary throttle body manifold recall 3 months later my wastegate actuator rod broke in half the dealer wanted 1600 dollars to replace the turbo and wastegate I fixed the problem myself almost 8 months later of driving without my turbo once the ride was replaced the car ran fine for 7 months once the cold weather started same symptoms re occurred
Probably a bit late to reply, but i had exactly same problem and now my engine has seized up, so please get it checked out immediately by Audi service center.
