At around 20-30 miles per hour my ears just about bleed from the air pressure vibration caused by my moonroof being open. The problem goes away if I close the roof a couple of inches, but I was wondering if anyone else has had this problem, and if it was something that can be fixed under warranty by BMW... This also occurs when the front passenger side window is open at highway speeds (although it's not as bad as the roof at slower speeds). Any thoughts??
