Vehicle: Mercedes-Benz E-Class W212

Compatibility


Suitable for selected:


* Mercedes-Benz E-Class W212 E350 CDI

* Mercedes-Benz E-Class W212 E350 BlueTEC, where fitted with the matching pump

* Mercedes-Benz vehicles equipped with the OM642 3.0-litre V6 diesel engine

* Selected saloon, estate, coupé and convertible applications using the same vacuum pump specification


Compatibility may vary depending on engine code, production date, emissions specification and vehicle equipment.


Technical Information


The vacuum pump supplies vacuum pressure for systems that require engine vacuum assistance.


Depending on vehicle specification, it may support:


* Brake servo assistance

* Turbocharger control

* EGR system operation

* Vacuum-operated engine controls

* Other vacuum-controlled components


The pump must match the original unit in part number, mounting arrangement, electrical connection and drive configuration.


Common Reasons for Replacement


Replacement may be required due to:


* Reduced or inconsistent vacuum pressure

* Hard brake pedal

* Turbocharger control faults

* EGR or actuator-related fault codes

* Oil leakage around the pump

* Damaged housing

* Worn internal components

* Excessive noise

* Vacuum system performance issues


Important Diagnostic Information


Before replacing the pump, inspect:


* Vacuum hoses and connectors

* Brake servo vacuum line

* Non-return valves

* Vacuum reservoir

* Turbocharger actuator

* EGR vacuum controls

* Electrical wiring and connectors

* Pump mounting seal

* Engine oil contamination or leakage


A vacuum fault may be caused by a split hose, leaking valve or faulty actuator rather than the pump itself. Vacuum pressure should be tested before installation where possible.


Installation


Before fitting:


* Compare the replacement pump with the original

* Confirm the part number and connector configuration

* Inspect the drive mechanism and mounting face

* Replace the sealing gasket or O-ring if required

* Clean the mounting area

* Ensure all vacuum hoses are correctly connected

* Check for leaks after installation

* Clear any stored fault codes and test the vehicle


Follow the manufacturer’s recommended fitting procedure and tightening specifications.


Important Compatibility Note


Please compare your original pump carefully before ordering.


Check:


* Part number – A6422301027

* Engine code

* Vehicle model and production date

* Electrical connector

* Mounting points

* Drive arrangement

* Vacuum outlet configuration

* Brake and emissions system specification


Mercedes-Benz used several similar vacuum pumps across OM642 applications, so matching the OE number and physical design is strongly recommended.


Condition


Used genuine Mercedes-Benz part.


May show normal cosmetic marks, scratches, dirt or signs of previous use and storage. Please inspect the supplied photographs carefully for the exact condition, including the housing, mounting points, connector and vacuum outlets.


Ideal genuine replacement for a faulty, leaking or worn Mercedes-Benz E-Class W212 E350 CDI 3.0 vacuum pump.
