The generally accepted wisdom is that if your drive with your oil level overfilled, you WILL damage your engine. That is probably why Mercedes incorporated a warning of overfilled oil and also warn you not to do so in the operators manual. But hey! What do they know?
In general, oil is stored in the wet sump and is pumped around your engine for lubrication (and cooling) purposes. If your oil sump is overfilled, the crankshaft will be able to reach and beat the sump oil into a froth. The oil pump is not very good at pumping froth, and anyway froth is not very good at lubrication.
(There are some very sub-standard techs amongst the Mercedes Dealers. I think they only use the good guys for difficult jobs. I even had someone at my dealer put the wrong spark plugs in my C36...how basic can you get for a tech?).
