Picked up my 2021 M3 refresh about a week ago and noticed once driving a wind/whistling noise between 25-45mph. The noise goes away above 45-50mph, seeming to come from the passenger side. Anybody else had this?
After extensive use of painter tape, found I could eliminate the noticeable (any “car people” that drive with me comment on it, so I know it’s not just me) whistle by using a small amount of painter tape on the wind facing side of the passenger mirror where the black trim meets then white mirror cap.
This is where the mirror folds, so not quite sure how to fix this. Guess I’ll schedule a service appt to see if they have a fix.
