FAQ

Q1: How do I confirm this injector nozzle fits my engine?
A: Please check your vehicle’s engine code, which is typically found on a sticker on the timing belt cover or in the vehicle’s service manual. This part is specifically designed for the Mercedes-Benz OM651.901 DE18LA engine. Also, verify your existing injector part number against our list (EJBR04701D, A6640170021, etc.).

Q2: Is this a complete injector or just the nozzle tip?
A: This is a complete common rail injector nozzle assembly. It is ready for installation as a direct replacement unit. It is not just the internal nozzle tip.

Q3: What maintenance is recommended after installation?
A: After installation, it is highly recommended to clear any fault codes from the engine control unit (ECU) using a diagnostic scanner. For optimal performance, ensure your fuel system (fuel filter, fuel lines) is clean and free of contaminants. Regular use of high-quality diesel fuel is also advised.
