What Is the PSE Pump?
The PSE (Pneumatic System Equipment) pump generates vacuum and pressure used by several pneumatic convenience systems in the vehicle. It is separate from the convertible-top hydraulic pump.
Common Symptoms of a Failing PSE Pump
- Doors will not lock or unlock normally
- Remote central locking not operating correctly
- Trunk will not release normally
- Pneumatic functions operate intermittently
- Pump runs excessively
- Central locking system stops functioning
- PSE-related fuse repeatedly fails
These symptoms can also be caused by damaged pneumatic lines, leaking actuators, wiring problems, water intrusion or other components. Proper diagnosis is recommended before replacing the pump.
Condition
Used Genuine Mercedes-Benz OEM part.
This is an original Mercedes-Benz component and not an aftermarket reproduction. Normal cosmetic signs of use may be present. Please review all product photographs for the exact condition and configuration of the unit being sold.
Important Installation Information
Replacement electronic/pneumatic modules may require vehicle-specific diagnosis, initialization or programming depending on the vehicle and equipment configuration.
Always correct any pneumatic leaks or water intrusion before installing a replacement PSE pump. An unresolved leak can cause the replacement pump to run excessively and fail prematurely.
Please Verify Before Ordering
Match OEM part number 2308000048 / A2308000048 with your original unit whenever possible.
If your vehicle currently has another revision such as 2308000648, verify compatibility for your specific VIN and equipment before purchasing.
