SL 55 AMG
seat belt clicking noise
Anyone hear the seat belt tensioner on the top of the seat back make a clicking cycling noise that continues longer than it should? I'm thinking it's some sort of sensor? Any advise is most welcome..

Click/Clack noises are the seat belt automatically tightening...
Both my SL55 and my SL65 make the subtle but annoying click/clack noises randomly from what sounds like the door post area but only when the top is down.
I kept telling the dealer about it an of coarse they had absolutely no idea what the sound was... Then I was talking to the factory rep and he knew exactly what the noise was...
It is the seat belt tensioners automatically tightening...
The rep said the noises come more often the faster you drive and happens only with the top down. I am not sure what the position of the top has to do with the safety belts?
But he was right.
