I've seen all the posts in the past about speaker buzzing that sounds like a pretty common problem. I have it too (passenger door), and the dealer has tried to fix it twice now. They have just made it worse, even after replacing the speaker. Did anyone have any luck? I didn't see anyone say they got it fixed.
Also, when I go over bumps, there is a noise that sounds like it's coming from where the shoulder belt goes into the pillar. I heard the exact same thing in a 325i loaner. Anyone having that problem? The dealer says they can't even hear the problem when they drive it, but I know it's real, and it's annoying. I just think they can't fix it, so they say they can't hear it.
