    Air leak from driver's side at over 220 km/h

    At speeds over 220 km/h, I have a rushing air noise coming from the driver side door, seems like from the area of the rear-view mirror. It is definitely not just outside noise. I can compare it to cracking a window at high speed.

    Plus, the passenger side is ok, so I am not ready to accept the official reply from the factory that at this speed, something like this can be expected.

    Our Porsche service took the mirror apart and made steps to put in more insulation and it was fine during a test drive on the same day up to 270 km/h.

    It is now doing it again. I want to ask, does anybody have the same experience and what have you done about it?

    Thanks very much

    No issues at all at well over 220km/h (C2S). The only time the sound changes a bit is in a cross wind.

    Not sure about our cars but on another car I had to shove a bit of rubber material _between_ weatherstrip and door frame. I used grease paint on entire weatherstrip and found where it did not transfer to metal of door "frame." Where it did not transfer, it did not contact and there was the gap which produced annoying wind sound.

    Here's another possibility: the dreaded whistling mirror.

    Thanks for the reply and nice photo, I will have to check that out and try out both techniques.
