Suspension / control arm problem on '00 S500. <SQEAKS all the time!>
You can check my post in the CL-forum titled "Shocks, struts, and squeaking." There's a link that cabbe posted which was a previous discussion of this squeaking problem.
It could be your struts, control arms, ball and joints, or even bushings. It can be a matter of lubrication or replacement of parts. Since you have a 2000 Sonderklasse, the vehicle is up there in mileage--seems like a matter of wear and tear, an inevitability of course.
