Assuming that the earlier setup is the same as that on th ur, come 1985....

One actuator (drivers door) has an integral switch. This is the control valve.
The other door has a similar valve, but no electrical connection, and so is an operating valve.

The key turns the lock.
The various interlinking rods inside the door cause the control valve to move. The switch is made, which signals the vacuum pump, and the other door(s) unlock under vacuum control.

From inside, moving the locking button up or down on the drivers door causes the same thing to happen.

It always seemed odd to me that audi were so tight in putting only one control valve in on the B2 chassis. (The vacuum pump takes only one door locking signal, to my knowledge)
