Talk about timing! Our 96 C280 with 68k just started doing the same thing last month. If you find a fix please let me know.
Also, does your high mount brake light rattle with even the slightest amount of bass? Looks like I'll have yet another weekend project coming up, though I'm not sure I want to touch the car after fixing over 100 tiny rocks two weeks ago.
