Mercedes PSE Pump W210 W211 W220 Door Locks Won`t Lock - Repair & Modification Improvement

The PSE ( Pneumatic System Equipment ) Central Locking PSE Vacuum Pump operates the doors, boot ( trunk ), headrests, Multi Contour Backrest (Lumbar Support Bladder all four seats) and fuel cap cover flap with pressure. It either increases or decreases the pressure in the lines causing the movement of pistons in actuators, which in turn move levers in these various latches. The PSE Pump can both create pressure or vacuum. The negative pressure (vacuum) pulled by the PSE Pump operates the retraction of various actuators but it can also function to retract the Boot/Trunk Handle.
