MERCEDES W204 W212 W639 W906 OM651 DIESEL FUEL FILTER WITH SENSOR

This listing is for Mercedes-Benz diesel fuel filter A6510902952 with the sensor / electrical connection configuration shown in the actual product photograph.

Before ordering, compare your existing filter for: part number, electrical connector, sensor connection, fuel hose arrangement, mounting points, engine code and vehicle application.

Similar-looking Mercedes fuel filters can use different sensor/electrical connections. Please do not order using vehicle year alone.

ITEM DETAILS & EBAY ITEM SPECIFICS

WHAT DOES THIS FUEL FILTER DO?

The diesel fuel filter is positioned in the vehicle's fuel supply system and helps remove contamination before diesel reaches the precision high-pressure injection system.

Modern Mercedes OM651 diesel engines operate with extremely fine fuel-system tolerances. Contaminants entering the injection system can contribute to excessive wear or poor operation.

This particular version also has a sensor / electrical connection configuration. The connector arrangement must therefore be compared with your existing filter before purchase.

📍 WHERE IS THE PART FITTED?

The filter is located within the engine compartment in the low-pressure diesel fuel supply circuit.

Exact mounting position differs between C-Class, E-Class, GLK, ML, Vito/Viano and Sprinter applications.

• Earlier W639 models using a different filter arrangement.
• Sprinter W906 variants fitted with a different engine/filter specification.
• Vehicles with a different sensor or electrical connector.
• Vehicles with different fuel hose positions or connection diameters.
• Vehicles where the existing part number does not correspond with A6510902952 / A6510901552.
• Later Mercedes chassis should not be assumed compatible simply because they use a diesel engine.

🔎 HOW TO CONFIRM YOU ARE ORDERING THE CORRECT FILTER
