Hello,
I noticed that at 95+mph it's possible to hear a quite annoying whistle because of air pressure over the car at high speeds. I never noticed it for several months until I had the opportunity to drive the car over 95mph.
the whistle is really very annoying. I did some experiment and the whistle disappears if I tilt the sunroof. So it must be the sunroof the cause of the whistle. Anyway the sunroof works fine, it opens and closes, and it closes well all the way at it should be.

No air leaking neither water leaking... so it must be the air hitting the sunroof contour rubber. Anyone noticed this on their own x300 and has a workaround ?
thanks

 

No real answers, but I used to notice a similar thing on my x300 when driving at speed. My whistling came from the drivers side window and it would pretty much disappear if I cracked the window open, just a degree. Not actually opened, just not closed up tight. I never got around to solving it entirely, but I suspect that the rubber seal was probably worn somewhat.

 

....no idea, but it sometimes can be the most minor thing.

I once had a tiny leaf's edge tapping on the bottom of the windshield due to wind buffeting, that sounded like a rock rattling against the glass.

 

Yeah, I experience the same thing, it picks up at around 95 and gets slightly worse around 100, almost feels like the driver side mirror but it's probably just the chrome trim or a rubber seal on the door. I find it annoying too because other than that travelling at this speed would be pleasant. If you figure it out please reply here! Thx
