I picked up my car from the dealer on Friday because they put new door seals on because the old ones were making a creaking noise. That day, I took my 530i for a road trip to San Diego to Vegas this weekend and noticed a high pitch humming type of noise. The noise would start when I got up to about 95mph and would go away if I slowed down. I believe it's coming from the top of the windsheild seal maybe. I thought it might be the window or the sunroof seal but when I opened them up slightly the noise was still there. Another wierd thing was it only happened when the outside temperature was around 90 degrees. Once I got out of the desert area, the noise went away, even if I went upto 110mph. Any else have this issue?

 

Known defect with windshield seal. Search the forum for 'high pitch' you will see a ton of posts about this. Its not related to your door seals and it makes sense that as the temp rises the rubber winshield seal would expand and close the gap causing the whistle

 

Thanks for the heads up.

Both the seal creak and the windscreen noice problem after some 120 km/h are known problems.

Luckily my seals are OK and our speed limit is 120 km/h on freeways (read 140 km/h or about 90 mph).

 

 

Great, since your with BMW see what they can do about my sunroof. It whistles all the time and the wind noise is poor. I am a moving adversement for BMW's competition. I have several customers in my car they all here the noise and comment.

I proudly tell them I took it to BMW of Dallas and I was told by Mario that is the way it is designed and nothing can be done to stop the noise. I also got a follow up call from BMW to check on my satisfaction and I told them a $70K car should not have this problem and I was told "We are sorry." Well I an too for you guys because I proudly drive my car with high end people listening to your great design.

Believe me it has cost BMW sales because several have purchase other cars because of my problem. I look forward to seeing if you can fix this problem for me. I will continue to do my part to help BMW lose sales until this problem is solved.
