Dinan M3,
Thanks for your note. I spent the later part of yesterday afternoon down at the dealer "helping" the tech. Thanks to X5Jay, we focused upon the windshield as the culprit. By pushing on the inside of the windshield at high speed (i.e., while it was howling), we were able to change the pitch of the noise. Back at the shop we were then able to identify an area at the top of the glass which appeared to subtely "flex" away from the frame when pushed upon from inside, suggesting improper gluing of the windshield during assembly (wanna bet models assembled in Germany don't have this problem?). Once we determined that the problem was due to poor windshield adhesion, I requested that the dealer immediately replace the windshield under warranty...citing the situation as being a safety concern matter (e.g., what would happen during an air-bag deployment if the windshield is not properly affixed?). Once it dawned on the service manager that turing me away might pose a liability to them if there was an accident, they quickly got to work. If you need back-up info on my particualr warranty claim I'd be happy to oblige. As for yours, given the problem occurs at a higher speed than mine, might suggest your situation is less severe than mine....which might make identifying it a little more difficult. Anyways, if all else fails, a good glass shop should be able to remove and reinstall your windshield. Make certain the vehicle sits in the warmth for ~24 hours post installation to ensure that the bonding compound is fully cured. Hope this helps and Thanks to the prompt respondants to my original note. Happy New Year!
