Sorry to revive such an old thread, but it appeared the most relevant.
I seem to be getting wind noise through my E92 driver window, i.e. it doesn't seem to be as solidly sealed as it used to be. I have excellent hearing and am very sure this is a new noise. It's not that annoying, but I do notice it, and am wondering if others have this issue. There is a little side-side play in the window when the door is open, but none when the door is closed and no more than the passenger side where I don't seem to be getting any wind noise. It also appears to be functioning normally when it automatically drops/raises when closing/opening the door.
It may be a winter/extreme cold thing, hopefully it will work itself out, but I'll probably try the gummi pflege at some point. (I'm not going to be using the car much for the next couple months)
