Just recently I noticed loads of wind noise coming into the my CLS 350 so i had a look to see what was causing it. Anyway i noticed that when the passenger door is closed and the window goes up automatically, it does not sit flush on the side rubber seal which leads a to a thin gap leading to the noise at high speeds.

Can anyone guide me on how i can adjust the window or door for it to sit flush or do i have to take it to the dealers?? Any help would be much appreciated.
