so no one has had this on their E90? I have a 330i with sports:
* drive on the highway
* accelerate past 85MPH (please, you'll survive, trust me)
* do you hear a whistling sound coming from the air vents?
* it's as if side-wind is making this noise... Really annoying.
Didn't want to take the car to the dealer because I didn't think they could easily track and fix it.
