help power close assist went out
First my front doors went then the rears and trunk on mt 01 s500. Why would they go like that. Is there a pump involved? Sensors, fuses. What should I check first. Has this happened to anyone else? What was the repair cost? Thanks.

i had to jump my car due to my battery going out. afterward- my power assist didn't work either. took it to the mechanic and he put it on diagostic and cleared the codes the car picked up and everything works fine now. take it in and have them put the machine on it.

I had that happen on my '04 but only on the passenger front. I took it in and found out that the vacuum pump controls that as well as several other functions. There is a circuit board related to the pump that go's bad so MB replaces the unit as an assembly. Seems like you can't do the board w/o replacing the pump. There are a few relays involved as well but in your case with multiple failures, my vote is on a unit replacement. Mine was covered under warranty. I think I asked what it would be self pay and I think they said about $750+-..don't qoute me. Good luck.
