Anyone elses wing mirrors whistle at speeds around or in excess of 60mph, progressively getting worse as you go faster?
Mine do and always have. I mentioned it to my dealer once and they said they couldn't find anything wrong and would have to strip it all down (to probably not find anything anyway

) so I told them to leave it. My passenger side one is noticeably worse, the drivers side is comparatively quiet but it still does it. A few days ago I noticed loads of black sealant on the passenger mirror. It looks like the dealers tried to fill the gaps but when it's got hot it's actually melted a bit and ran down. I got rid of most of it pretty easy with IPA. I did call them to have a moan but couldn't get through to anyone in service, they returned my call a few days later but I just ignored it, at least they tried I guess (but failed miserably).

So has anyone else got this? Most annoying thing in the world when driving with the windows open. Can't hear it when they're shut.
Cheers,
Scott
