I've recently noticed an issue that when I go over a bump just at the right spot there is a rattle in my f32 coupe above the rear seats, the black trim piece is loose however I'm not sure if that is the culprit, additionally if I'm playing music with a good amount of bass in it that cover tends to rattle and drive me nuts.

If anyone has ideas as to what it could be and a possible fix for it I'd be extremely grateful.

Don't know about the black interior trim piece as I have a sedan, but my F30 with hifi system (which is the base system in US I believe) rattles like it's falling apart if you stand on the outside while it's busting a tune with a fat bassline. Worst culprit are the rocker panels (I have an M Sport). From the inside it's ok, but the outside does not sound like quality at all. It's kind of embarrassing.

Yep, rocker panels on my F31 also rattle quite bad. It really is quite embarrassing.

The rocker panels are extensions of the underseat woofer enclosures, so they're going to rattle.

Interesting, funny enough after this post the vibration sound has seemed to disappear, its either that or the new exhaust setup LOL
