Purpose of the Part

The electronic unit pump generates high fuel pressure and controls fuel delivery to an individual engine cylinder. It helps ensure the correct amount of diesel fuel reaches the injector at the proper time, supporting smooth operation, consistent engine power, and efficient combustion.

Issue Symptoms / When to Replace

Possible signs of electronic unit pump problems may include:

  • Hard starting or extended cranking
  • Rough idle or engine misfires
  • Reduced engine power or poor acceleration
  • Unexpected engine stalling
  • Fuel injection-related fault codes

These symptoms may also result from injector, wiring, or other fuel system issues. Proper diagnosis is recommended before replacing the unit pump.

Brand Information

Bosch has been developing diesel fuel injection technology since the 1920s, introducing its first diesel injection pump in 1927. In 1995, Bosch introduced its Unit Pump System (UPS) for commercial vehicles, allowing individual cylinders to receive electronically controlled high-pressure fuel delivery. This technology became an important part of Mercedes-Benz heavy-duty diesel engine fuel systems.

Installation Notes
  • Sealing: Replace all three unit pump O-rings during installation to prevent fuel and oil leaks.
  • Fuel System: Eliminate fuel contamination before installing the replacement pump.

How to Identify an OEM Part

Look for the Mercedes-Benz three-pointed star logo and A0290742002 identification number on the pump's black label, along with the Bosch part number and manufacturing markings.
