There are some recent threads on this topic. I had this problem of noise, etc. on that A.I.R. pump. From this site I gathered that the pump really is not needed and serves no purpose beyond the first minute after a cold start. Examining the pump in-place (560SEL) it could be seen that the pulley/clutch assembly was not functioning--pieces actually fell out. I cut the drive belt. Noise problem stopped. Car runs OK since. Recently I asked Donnie of MB Motor Werks (this sites sponsor) if there could be adverse consequences for disconnecting the pump. Reply was that unit only works for that few seconds following a cold start. No mechanical consequence.
