I recently purchased a Year 2000 328iS with the Sports Premiun Package/5 speed and I have noticed that above 70 MPH there is a distinct wind noise coming into the cabin on the drivers side. In the passenger side the noise is not as bad. I took it to the dealer and they think( after driving it)the wind noise is due to the new mirror design being used in the E46 platform which is causing turbulence; This is a little puzzling since you would expect a similar wind noise on the passenger side; they claimed that they have seen a few other E46 cars with a similar problem. BMW has not come up with a solution yet. The dealer plans to contact me as soon as they hear back from the factory. Has anyone experienced a similar problem?
