I dont believe a pump failure in the central locking system is the only way the system can malfunction. I would check this before having the pump swapped out.

If I were you I would take this car to a highly reputable Mercedes-Benz only mechanic such as Enrique. If you want the best MBZ master tech in California you need to go to Enrique. His shop is called Mr. MB Motors and its on Reseda Blvd. in the San Fernanado Valley in Los Angeles.

The issue you're having with starting must be first checked by checking the codes. Did you see your tech do this? Were you standing there while he checked the codes?

I would not leave your 12 cylinder sedan in anyone's shop. Just my opinion.

BTW, I was at Enrique's the other day and met a guy with the same car. Midnight blue 1992 V12. And of course Enrique is the only mechanic that works on it.
