OE: 0024770601 Fuel Filter for Mercedes-Benz CDI Diesel Engines | Mercedes-Benz

The OE: 0024770601 fuel filter is designed for Mercedes-Benz diesel vehicles equipped with the early-generation CDI engines.
It supports stable fuel delivery by removing fine contaminants and moisture before fuel reaches the high-pressure pump and injectors.
This filter helps maintain smooth combustion, reliable torque output, and consistent performance during urban driving and extended highway use.
Its construction supports long-term operation across varied climates and fuel-quality conditions.

Compatibility

This fuel filter fits Mercedes-Benz diesel models powered by the following engines:

• OM611 CDI engine

• OM612 CDI engine

• OM613 CDI inline-six diesel engine

Supported applications include:

• C-Class W202 / W203 Diesel

• E-Class W210 / early W211 CDI models

• Sprinter W901 / W902 2.2CDI and 2.7CDI

• Vito / V-Class W638 Diesel

These engines rely on clean and consistent fuel flow to support accurate injection timing.
The filter serves as the main fine filtration stage in the CDI fuel system.
Its metal housing, connection points, and sealing surfaces match OE specifications for direct installation.
It performs reliably in regions with varied diesel quality and mixed operating conditions.

Filtration / Material / Mechanical Design

The unit features a multi-layer synthetic filtration medium designed to capture small particles without restricting flow.
A reinforced metal housing ensures durability under pressure fluctuations and temperature changes.
Integrated water-separation components help reduce moisture content within the fuel circuit.
OE-grade seals maintain stable pressure and protect against air intrusion.
This design offers reliable performance in warm climates, high-traffic regions, and long-distance driving.

Flow Stability & Engine Protection

Clean fuel supports smooth combustion and accurate injector spray patterns.
The filter helps maintain stable idling and dependable cold-start behavior.
Consistent filtration reduces stress on the high-pressure pump during heavy use or steep load conditions.
By eliminating contaminants, the filter supports long-term reliability of CDI injection components.
