I'm still dealing with 3M and BMWNA because immediately after 3M install, my driver's side mirror started to whistle. I have an appointment next week to get it reinstalled to see if there's a fix. A search will turn up a few threads from folks with this same problem.
It's not a consistent issue, so I really don't understand whether it's the mirror, the film, or some combination of both. BMWNA insists it's not the physical design of the mirror. 3M insists their film doesn't do this, but my installer has had another 135i have the same problem. They replaced the mirror and put new film on it and it still whistled.
And I'm definitely not smoking crack.
