Ditto to checking the W210 forum and look in the sticky threads. There are a lot of do it yourself threads and I'm pretty sure there is one for that in there. The sound could come from a couple of places; like the common gasket in the rack and pinion steering, to the power steering pump, to low fluid level. It might even be the rack going bad but I hope not! If the fluid is low, you'd better look for a leak.
