That's good to know Dan, maybe I can fix this pump then.

Yeah, that’s one of the “smart” pumps. They can be opened and serviced. No
electronics to speak of if they like the W140 and W210 versions, but some
contacts that can be adjusted to control state change (pressure/vacuum) and
high/low pressure/vacuum thresholds.
Lots of info on BW on these as I
Looks like this pump was common to all the 124 cars as well as others.

I've got the pump from Wilton's sedan, should be able to swap that in and
have an answer.

There was an early Hella 126 pump that was quite stupid, but I've only ever
seen one of those. As one might expect, the diaphragm on the snap switch
failed. The later pumps are bidirectional motor/pumps, with electronics. Far
fewer moving parts.

Don't know the answer to that, I'm speculating now. I've got some research
to do about which pumps are shared and which are unique.

Are the pumps on the late W124s a separate unit like PSE pumps on later models,
or the “dumb” kind like the “football” found in W126 models?
I ask because the “dumb” pumps don’t have any logic, just a pressure actuated
snap switch that reverses rotation, changing from vacuum to pressure and

Yes, if the signal from the door lock is indeed correct, it is. At this point
diving into the
pump can't hurt. My first suspicion would be bad solder joints, but re-capping
too while
you're there

I was thinking that the driver's lock is set for sending a constant unlock
signal, but that cannot be because when I lock / unlock that, it has no
effect, so that wire must be disconnected or broken / grounded or something.

This is 124, not 210, and I don't (yet) have an SDS computer. Perhaps this
124 does have some rudimentary diagnostics via the impulse counter
connector by the battery, worth looking in the documentation to see if that
is a thing.

No, I'll take a look there. I'm sure you're correct, someone has btdt and
written up the process to fix.

Electric switches in the locking mechanism, sends signals to the pump to
provide either vacuum or pressure.

Scratch that. I was thinking W210, not W124.
Sorry.
I would look to the door switch.

These later (W210-up) central locking systems rely on what’s known as the “PSE”
pump. It provides both vacuum and pressure, along with supplementing vacuum for
the ACC system when values drop below a specific point, or when the engine
isn’t running. The PSE pump does a lot of “thinking” for the
the drivers door has a lot of electrics which control the vacuum pump.
If I recall right, it is actually vacuum one way and pressure the other
way, so you have both electric and pneumatic systems to deal with.
The vac pump is under the back seat cushion, right side. The trunk and
So that would suggest the switch(es) in the lock(s) has gone wonky.
Door lock not switching, trunk lock in a panic

Have you done a Google search on BenzWorld’s W210 forum? It’s probably outlined
there.

Are all 124 and 201 locks powered by vacuum via electric lock pump, or just the
early ones?
