Central Locking Vacuum Pump Motor Mercedes-Benz W140 W210 W124 – PSE Pump Motor Replacement
This vacuum pump motor is designed to restore the functionality of the central locking system in Mercedes-Benz vehicles equipped with a PSE vacuum pump. Over time, the original electric motor inside the pump can wear out, causing the central locking system to malfunction or stop working completely.
Owners of Mercedes-Benz W140, W210 and W124 models often experience issues such as the central locking system not responding to commands, random locking or unlocking of the doors, or the pump running without properly building vacuum. In most cases, the root cause is a worn or failed vacuum pump motor.
Replacing only the electric motor allows you to repair the PSE vacuum pump without replacing the entire unit, saving significant cost while restoring proper operation of the central locking system.
This motor is manufactured to match the specifications of the original unit and provides reliable performance and long service life.
