When driving on rough roads, if I open the passenger window on my C30 I hear an annoying rattle.
I think it might be the heat shield, but when I look, it isn’t hanging off and the noise is more like a one time “tinny” bang, as though the heat shield is banging on the underside of the car.
I’ve taken it to my mechanic but he said he can’t find anything.
I can’t hear it if the windows are closed and it isn’t causing any issues with the running of the car and Volvo have done a vehicle health check and I’ve just had the rear suspension arms replaced as they were rotten but the sound persists and it just drives me crazy knowing its there and cannot pin it down.

Anyone know what it might be or experienced this before?
