Dear all, i have a slight whistling noise when my speed touches 120kmh and above. It appears to be coming from the front passenger door. Car model is BMW 520d F10. I check and there are 2 rubber lining on the door and 1 rubber lining that sticks to the body of the car. I have changed the rubber lining that sticks to the body but sounds persists. Anyone had this problem and managed to resolved it? Would appreciate your kind advise.
