Wind Noise from Door Mirrors

Dephead2004 · 11-17-2018, 11:36 AM

If you have a whistling between 45-55 mph from the door mirrors then it maybe that you would benefit from a n application of silicon mastic to the underside of the mirror where it joins the door. From the factory this is unsealed. A short strip of silicon will close the gap and reduce the wind noise.
Done it on both sides of mine and enjoying the bliss.

can't say I've never noticed any noise from the mirrors, at any speed.
(may be because I have my banging tunes on?!)

Maybe! My favourite is the sound of silence

Dephead2004, do you really hear the difference? I also have the feeling that it's a bit too noisy.

Yes, I do. The turbulence is much reduced. As in op above, I had a distinct whistle at 45-55 mph. That's completely gone now.
Inn any case is so cheap and easy to apply, fix and remove of you don't find it works. The secret is to use a very fine bead.
I had previously applied silicon to the gaps between the two parts of the mirror shell. This was ineffective for the whistle. I left it as it doesn't to any harm and is invisible.

Never had an issue with wind noise in my 530i. This car is amazingly quiet at highway speeds.
