So is the general consensus that this is all airbox related?? I test drove a used m3 dct yesterday, and heard, upon acceleration, a rattling/fluttering...like wind trapped under paper....from what seemed to be the front left part of the vehicle? Almost a "crackling" or "rustling" actually...hard to describe. It wasn't there when the car was revved in neutral...
