I love my 13 F30-335i, BUT the wind noise issue is so frustrating. I've been through several Dealer Service depart visits, including a ride with the Service Manager with no resolution. Service Manager said he has seen this problem in a host of F30s and the BMW has not addressed/ or owned the issue.
I've had the problem when i had the original RFT's and my Michelin Super Sports, on all road surfaces/conditions. It manifests itself starting at about 45 mph in any of these conditions and also appears to be located in the upper "B" pillar area.
I may try inserting a flexible 1/4" line inside the door gasket to see if by thickening it, it reduces the noise.
