I've a 99 e430, when driving on uneven roads there is an annoying rattle in the roof just ahead of the sunroof. I removed the center light/sunroof switch assembly and can dampen the rattle by pushing up on the sunroof motor. It sounds like a loose control cable - are they easy to adjust?

BTW the sunroof is working fine. Has anyone had similar problems? Any suggestions on how to fix?

thanks in advance,

Peter
