Re: Wifes' new GT - terrible wind noise.
I had this problem initially in the 156 SW
Changed the seal and it was still apparent,so using my finger tips to pull the top part of the door gently inwards whilst travelling seemed to cure the whistle.
So when i got back home i realised that the door frame not pushing up against the seal seemed to be the issue
I put a small block of wood up against the door at the bottom and pushed the top part of the frame in gently(with the glass down)a few times and this did the job,hoorah no whistles any more !
