Scott:

Take a look at the Mercedes diesel parts list for the door lock/un-lock
parts.

My wife's '82 240 D sedan runs all the door locks plus (some other stuff)
using vacuum. The driver's door has an exquisite little master valve that
switches vacuum to the other doors to operate the lock and un-lock
mechanisms. the thing will hold vacuum for several weeks and the locks will
still operate so there isn't much leakage (the car has an "accumulator" tank
that "stores" the vacuum when the engine driven pump isn't running.

The valve is plastic, about two inches long and maybe 3/8th inch in dia. It
has a metal plunger with O-ring seals and is cross-drilled at one end so you
can connect something to it. The valve body has slip-on hose bibs that look
to be about 1/8th to 3/16th inch dia.

I found out about the valve when I  bought one for her car and then found it
wasn't needed (lousy troubleshooting) - think I paid about $5 or so for it.
