Not sure either! We'd have to take off the inner plastic to get to the flap. Then could either: a) remove the flap, b) stick it down or c) put some soft felt around the plastic hole so that the rubber flap is flapping against that instead of hard plastic.

or D) Rev the t*ts off the car whilst waiting at the lights haha. Note: I only seem to get this happening at idle - must be resonanting with the exhaust or something?

I might have a go at it this weekend. Maybe!....
