Central Locking System PSE pump
2001 E55, 106,000+ miles
Learning this is a great system when it works. When it doesn't it really sucks.
It has been working off and on the past week or so. Since the weekend it is getting worse. If I wiggled the electrical connectors, sometimes that is enough. Today I had to lightly tap it to work. When releasing the trunk or locking, it really grunts/moans. Luckily it is stopping with the car unlocked.
I do know the line in engine bay is broke but semi held together and closed I hope.
Any help or ideas please. I'm a diy guy as much as possible. Thanks.

depends if you have more time than money. time- open it up and perform an exploratory
but you should know what you're doing and understand the odds are low in terms of recovery.
money - order a new one from the dealer $200+. time/money balanced- open it up and if
you screw up, try locating SAME PART number for a used pump and crossing your fingers as
you hook it up. some 210 models may require SDS diagnostic tool to handshake the car to
the pump...which, I'm guessing, your 2001 will need this

Thanks. Been doing a lot of reading on it tonight. Neat system, when it works. Right now, pump makes no noise at all. If I move or tweak the white connector, the rear dome light comes on and off.
The dealer part I fear will be a real pain. Nice design MB. Beautiful car, awesome performance but too much quirky Crap.

Mine failed because it got wet in hurricane Sandy. A few of the pins that connec to the lower connector plugs disentegrated. The locks worked (not well) but the trunk release and the back seat lighting did not. I found one on eBay for $60 that had all of the plugs intact and had been removed by cutting the cables instead of unplugging. I carefully cut one wire at a time from my pump and soldered it into the corresponding wire on the new pump and taped it up. It took about 90 mins since there are about 30 or so wires. Neatly put it back in its foam case, reconnected the battery and was thrilled when everything worked perfectly. In fact the "lock at 9 mph" feature started to work which never worked before.
The pump I bought had the same part number and was plug and play. No programming was needed. Also, my old pump utilized one pin on one of the bottom plugs that was blank on the pump I purchased. I swiped that one pin out of my old harness without any problem. I guess my car utilized one feature that the car the used pump came from didn't, who knows.
If your plugs are all in good shape, it's a much simpler install. All the harnesses and the module with the vacuum tubes simply unplug and reconnect to the new pump.

I picked up a 2108001948 at my local salvage yards. Identical unit at least in looks. I have not plugged it in yet. I have heard it may need coded to work since mine was a 2108002748. I would think the motor would at least be able to be swapped.
