Z4 window rattle

[KatyTX]

Has anyone else had this problem? Both windows have an annoying rattle at the window seal. The dealer has tried to fix it twice with no success.

Is it when the top is down, I had that for a little while, and it turns out it was the door hinge, but the rattle sounded like the window, if anything spray some WD-40 inside the hinge on the door.

Actually, it's only when the top is up.

Does it rattle when the window is up or down or both?

I had a 2004 Z4 loaner for 17 days, and it rattled like crazy with the top up, windows closed. Drove me mad. I think it is something to do with the frameless windows fitting in the thin rubber seals. If you look at the 3 series and 6 series cabrios, the tops seem to be a higher, thicker quality.

Well they did that because it is so much lower and less room between the trunk and the cabin.

It only rattles when the window is fully closed (i.e., all the way up). To make it more baffling, it typically doesn't start until I've been driving for 10 minutes or so.

im sorry I dont know what to do cuz I dont have a z4...this is more of a comment....sorry...

But what the hell is this! the thing just came out what like last year! I mean cmon BMW you can do better than that.

Ok...now that im done venting...I think maybe you could install some padded rubber strips at the tops of the convertible top to snug it up. But that would only help when the top was up.....sorry
