knocking/rattling noise from driverside door pillar

[AznWhite528i]

Just bought a 98 528i and I hear a minor rattling noise from behind the seatbelt on driverside door pillar, is something inside there loose? could it be from rear door, loose tweeters maybe? I only hear it when I go over bumps on the road, I'm assuming it's seatbelt components behind the pillar...Please help!

it is probably the door seals rattling. the dealer sells this really great stuff called rubber seal treatment gel. rub ssome of that on all of your rubber seals on the door and the door jam. should take care of it
