Pretty much got it diagnosed that the pump is failing.
D/S soft close and lock mechanisms not working.
Replacement of the pump seems to be straight forward.
New ones are $800+ at the dealer and the best online price I've found is $600.
I'm not enthusiastic about used ones on eBay.

Question is: are there any sources for a rebuilt pump?
This is for an 06 CL500 (W215)

Thanks in advance!!
