Descripción
This central locking vacuum pump is a genuine Mercedes unit for W220 models, supplied under OEM number A2208000278. It is the pneumatic control pump used in the vehicle’s central locking and related vacuum-operated comfort functions.
Its job is to generate and manage vacuum and pressure for the locking system, allowing the car to lock and unlock correctly through the connected pneumatic circuits. In Mercedes W220 applications, this pump supports smooth operation of the central locking system and helps the comfort system respond properly to driver commands.
Common signs of a faulty unit include doors failing to lock or unlock, intermittent central locking operation, repeated pump running noise, trunk release issues, or vacuum-related convenience functions working inconsistently. Internal motor wear, leaks, or damage to the pump assembly can all lead to these symptoms.
This is a used original part, removed from a vehicle and tested before sale. Please match OEM number A2208000278 before ordering. Professional installation is recommended, and because the pump works with multiple pneumatic lines and vehicle electronics, careful fitting and system checks are advised after installation.
