When driving with the radio off, I hear some rattling from the windows when going through bumpy roads. I think it's the windows. Any of you hearing this too, or should I get this checked out?

No rattles on mine - I'd have the dealer look at it as it shouldn't rattle.

I have rattling too. Quite not pleasant noise. It happens only on certain road when car vibrates with high frequency. There are no such roads near of my dealer so I have no luck to show problem and get fix of it :(

I visited my dealer for the 1200 mile service. Turns out that this is a common problem for several models, although they haven't seen it on the Z4(M). It's just the windows rubbing against the rubber seals. The dealer applied some silicone-based lubricant on the seals and the rattling went away.

I drive 06 M Coupe. My dealer say's tinting will cause this too. Say it's tinting rubbing on seals. Lube is suppose to help.
