• maintenance of optimal operating parameters in urban and highway driving.

Thanks to its OEM design, the module is optimized for the W166 Mercedes fuel system architecture, reducing the risk of diagnostic errors and compatibility issues.

Compatibility, Identification, and Specifications

The offered module belongs to the Fuel Pumps and Level Sensors category, meaning it combines the functions of an actuator and a measuring element within the tank. Part identification is based on the OEM number and interchangeable numbers, which facilitates selecting the correct component from the manufacturer's catalog or by VIN.

The product is designed for systems powered by gasoline fuel, therefore its operating characteristics – including material resistance and flow parameters – are adapted to this type of fuel and the specific engine units used in the Mercedes W166.

Condition, Benefits of Using a Used Part, and Installation Aspects

The module is offered in used condition, allowing for an economical repair of the fuel system while maintaining the original manufacturer's specifications. Compared to low-cost aftermarket alternatives, the OEM part ensures:

• factory fitment to the tank and electrical system,
• compatibility with the engine control unit software,
• maintenance of original fuel system operating parameters.

In most cases, installation is plug-and-play, utilizing factory connectors and mounting points. Before installation, it is recommended to verify system tightness, the condition of the wiring harness, and perform adaptation or error clearing in the control unit, if required by the service procedure for the specific model.

Technical Support and Selection by Numbers

To select the correct AdBlue pump module for a specific Mercedes W166 version, it is advisable to use the OEM part number and reference numbers, which allow for unambiguous verification of compatibility. In case of doubt, it is helpful to compare the markings on the removed part with catalog data and consult the service documentation.
