Was trying to establish if anyone has had the whistling - flute- wind noise from teh Trajet at high speeds resolved. If so what was the answer. Our dealer is having problems resolving this...
BTW the problem has been there since day 1.
The problem happens to be with the rubber surround on the door seal; all you need to do is take it off, clean it and re seal it.

Had same problem; Trajets can make whistling noises at high speeds due to faulty windscreen seals. The windscreen needs to be removed and the seals replaced.
