you didn't mention how the rapping sounded. does it change with the rpm. does it do it only while moving or does it sound off at a stand still? does it sound off on acceleration or deceleration. have you ruled out the engine compartment?

i am replacing a camshaft this week on my 420sel. i would describe that as a sharp rapping also. mine lunched a rocker arm wore down so bad i have to replace the camshaft as well.

with a bit more description we (the forum) may just figure this one out.
Thanks Much!
