Mercedes PSE Central Locking Vacuum Pump Motor for W140, W210 and W124
This central locking vacuum pump motor is designed for Mercedes-Benz W140, W210 and W124 vehicles equipped with a PSE vacuum pump system. It replaces the worn internal electric motor inside the central locking vacuum pump and helps restore proper locking and unlocking operation.
Over time, the original motor inside the PSE pump can wear out, causing the central locking system to stop responding, lock or unlock randomly, or run without building enough vacuum. Replacing only the electric motor allows targeted repair of the original pump without replacing the complete PSE vacuum pump assembly.

What This Part Does
The PSE vacuum pump creates vacuum pressure for the central locking system. The internal electric motor drives the pump mechanism and allows the system to build vacuum when the doors are locked or unlocked.
When the motor becomes weak or fails, the pump may run too long, fail to build vacuum, or stop operating completely. This replacement motor restores the drive function of the existing PSE pump when the pump housing and internal mechanism are still serviceable.
Compatible Vehicles
This central locking vacuum pump motor is listed for Mercedes-Benz vehicles equipped with compatible PSE vacuum pump systems.

- Mercedes-Benz W210
- Mercedes-Benz W124
Important: compatibility depends on the exact PSE pump version and motor shaft design. These motors can exist with shorter or longer shafts, so the supplied extended shaft may need to be shortened slightly for correct installation.
