ANybody have this problem...I hear a nosie kidda like a tapping noise at the passenger side. I tried clamping the seat belts its gone....but when somebody sitting on the passenger side with seat belts on i can hear the noise....bythe way this is with the sunroof tilt up...when i open the sunroof noise gets louder...when i close the sunroof i cant hear any noise ...i tired checking the sun roof but i dont know...

 

I get a thunking in the passenger door as well, always with rapid starts and stops.I guess a worker at MB lost a wrench when mine was being buiilt. Im waiting for my first service to have it looked at.
