Anyone have similar issues? or any other issues to look out for?
I think this is actually a design feature. If you look at the air dam that pops up it is really a mesh screen. The wind passing through the screen makes that noise. On my Volvo, the air dam is made of regular semi-pyramid shapes (kind of like the tank obsticals on Normandy beach) and it doesn't make any noise at all.

In either case there has to be something to disrupt the air over the top of the car or you get massive buffetting down through the opening. Next time you are out driving reach up and push down the air dam (it is just spring loaded) and you will see what I mean.

I'm guessing that BMW thought the wind noise through the screen was more natural than some of the other options.

FWIW
