I have recently demounted the rear bumper (B7 avant) and found the cause for the rattling noise outside the car when playing music with a lot of bass.
There are rubber flaps in the ventilation channel on each side of the car and the one on the right hand side gives a rattling noise when playing loud music.
I checked with the Audi garage and they said that the flaps have a mission and should not be removed.
Anyone who knows how to fix the problem?
