This Bosch ECU 0 281 021 137 is a genuine engine control unit for MAN trucks.
The part carries the Bosch number 0281021137 and the MAN number 51.25820-1050, which confirms its exact compatibility.

The ECU controls fuel injection, boost pressure and ignition timing. Because of that, it has a direct impact on power, fuel consumption and emissions. If your old ECU has the same numbers and shows faults, this unit is the correct replacement.

This is an original Bosch module. The connectors match the factory harness, so installation is easy and fast. In most cases you will still need programming or coding to match the ECU to your vehicle’s VIN. For this reason, it is always a good idea to contact a MAN specialist before installation.

The aluminium housing protects the electronic board from vibrations and heat. In addition, the multi-pin connectors provide a safe and stable electrical connection. The photos show the real condition of the ECU, so you know exactly what you will receive.

Use this ECU when you need a reliable replacement for a damaged, flooded or short-circuited control unit. It is a solid choice for workshops, fleet owners and MAN truck operators who want a tested and original part.
