My June-delivered X5 4.4 Sport has a very high level of wind noise. According to my dealer, "they all do that." In addition to noise at windows, with the driver side being louder than the passenger side, the moon roof is noisey also. According to the dealer, "they all do that" too, especially the 7-Series, although I had a 328 loaner and the moon roof, as well as the windows were quiet. Any similar experiences with your X? Any fixes?
