Rattles -> the problem is in the door. Observe and see where it's coming from. Retighten screws as needed and add felt tape. That's what I would do if I had to do it myself. If you're under warranty the dealer should be doing this I believe? If he refused go see another dealer. He they all refuse complain to BMW... You can also seek help in aftermarket car audio forums, should be a rather common issue for them.
