| I have the same wind noise problem from around ~140kph to 180kph. It just dissepears when I push hard the windhield (around the rearviewmirror area). Now the car is in the authorized BMW service. As I am told, they have faced that problem couple of times. They are going to check and rebound the rubber / windshield. Hope that solves the problem without any water leakage in the future. |
