FAQ

Q: How can I confirm if this pump (0445010517) fits my BMW?

A: While this pump is a common replacement for the BMW 120d, 320d, 520d, and X3 models with the N47 engine, it is critical to check your vehicle’s VIN number or the part number on your old pump. The most accurate way is to remove the pump and verify the Bosch part number (e.g., 0445010517) or the BMW OEM number (e.g., 13537808089) engraved on the housing. If these match, the pump is a direct fit.

Q: What are the common symptoms of a failing CP4.2 high-pressure fuel pump?

A: Common signs include difficulty starting the engine (especially when hot), a noticeable loss of engine power or hesitation during acceleration, the engine management light (check engine light) illuminating on the dashboard, and unusual metallic noises coming from the engine bay. If you experience any of these, it is crucial to have the fuel system inspected immediately to prevent metal contamination from damaging injectors and the fuel rail.

Q: What maintenance is required for this remanufactured pump after installation?

A: To maximize the lifespan of your new remanufactured pump, it is highly recommended to replace the fuel filter at the time of installation. Ensure you use high-quality diesel fuel and consider using a fuel additive to improve lubricity, as this is critical for the longevity of the CP4.2 pump’s internal components. If the pump failed due to contamination, the entire fuel system (tank, lines, injectors) must be thoroughly flushed and cleaned before installing the new pump to prevent immediate failure.
