2001 E320 Mercedes PSE Central Vacuum pump AC assist and door locks

In this episode I go over how to access the PSE central vacuum pump in a 2001 e320. the vacuum line from this goes to behind the engine that helps the air conditioning keep the flaps open.

I hate working on Mercedes for diagnostic work, i can never find good wiring diagrams...the shop i work part time at only had Identifix and I'm not impressed with it lol. What sources do you use for your car?

Hi, I had the same problem with a broken hose the one that goes behind the engine.
I did not have any air in the central vent coming out but now it works perfectly.
My central locking do not work I think I got something a problem somewhere any suggestions ?
Thank u.
