Just picked up an '07 MZ Coupe yesterday... What an awesome drive! I'm a newbie and a first time user of this forum... so please forgive me. There's a whistle/air sound coming from the passenger side. I can't feel any air leaks or find out where the sound is coming from... Anyone encountered a similar problem??

Diagnosing "problems" based on internet description of sound is like internet dating. Sure, once in a while you hit pay-dirt and end up with a hot-@ssed chick, but most of the time you just strike out.

I can only GUESS as to what causes a whistle sound. Maybe the window isn't closed tight?

I have this same problem on my car! I think the window just needs to be adjusted so it closes alittle tighter. One of these days i'll get around to taking it over to my tech.

i've see this on the mz4 too. the passgr window sometimes doesn't get super tight at around 100+ speeds u can start hearing weezing noise.

in addition i've noticed once in a while when someone slams the passgr door shut, the window drops itself down a couple of millimeters, enough to make that white hissing noise at speed.
