The BOSCH 0414799002 Electronic Unit Pump (EUP) is a genuine OEM diesel fuel injection component designed for Mercedes-Benz commercial vehicles, Freightliner trucks, and a wide range of heavy-duty industrial machinery. It is fully interchangeable with the authorized part numbers 0414799001, 0414799002, 0414799003, 0414799004, 0414799006, 0414799008, 0986445008, 0 986 445 008, 986445008, A0280746902, and 0280746902, allowing distributors and fleet operators to source a single SKU that covers multiple cross references across the 799 series.

Engineered for the Mercedes-Benz OM900 engine platform, this electronic unit pump is compatible with OM900, OM902, OM904, OM906, OM924, OM457, OM460, OM501, OM502, OM541, and OM542 engines. It is widely used in Actros, Axor, Atego, and Freightliner heavy-duty truck applications, as well as in construction equipment, agricultural machinery, diesel generators, and mining vehicles. The unit pump operates through camshaft-driven mechanical pressure generation combined with ECU-controlled solenoid valve timing, delivering injection pressures exceeding 1,600 bar for precise fuel metering and optimized combustion efficiency, while supporting Euro II, Euro III, and selected Euro IV emission standards.

Manufactured from wear-resistant alloy steel and factory-calibrated to Bosch OE specifications, the 0414799002 EUP ensures long service life, low emissions, and stable performance under demanding operating conditions. The fuel delivery process follows a controlled sequence: fuel enters the low-pressure gallery, the camshaft actuates the pump plunger to rapidly build pressure, the engine ECU commands the solenoid valve to open, and high-pressure fuel is delivered to the injector for atomized combustion. Routine maintenance is recommended every 20,000 km, 50,000 km, and 100,000 km to inspect the fuel system, check injector balance, verify injection timing, and confirm EUP solenoid operation. This makes the BOSCH 0414799002 a reliable and globally trusted solution for B2B replacement, remanufacturing, and OEM exchange programs.
