    I was wondering if anyone has come across this problem before.

    I have Audi A3 55reg (8P) 3.2 quattro DSG 3 door.

    Since I have bought it over a year ago it was making noticeable whooshing sound while waiting at the traffic lights with brake pedal applied enough to make it still. The noise was a bit louder when waiting on the hill (brake pedal applied harder).

    I have had brake discs and pads replaced all around recently and noise now become really unpleasantly irritating and acquired one more side effect. Now when the engine is cold it will run very rough when brake pedal is pressed hard to the floor. If kept like this for a bit it will go as far as throwing error below.

    18609 - Bank 1; System Too Lean off Idle
    P2177 - 001 - Upper Limit Exceeded - Intermittent
    18611 - Bank 2; System Too Lean off Idle
    P2179 - 001 - Upper Limit Exceeded - Intermittent
    18619 - Bank 1; System too Lean at Idle
    P2187 - 001 - Upper Limit Exceeded - MIL ON
    18621 - Bank 2; System too Lean at Idle
    P2189 - 001 - Upper Limit Exceeded - MIL ON

    I've popped in to the local Audi specialist garage and was told that this noise is normal and I couldn't demonstrate the rough running of the engine because it was hot at a time.

    Has anyone come across problems like that and if yes - what should be my next steps in order to get it fixed?

    Thanks a lot.

    Possibly a vacuum leak somewhere - check all of the small vacuum lines.
