A6461500577 Bosch 0281014203 – Mercedes 2.2 CDI Virgin Engine ECU

Original Bosch engine control unit used in selected Mercedes-Benz Sprinter vehicles equipped with the 2.2 CDI engine. The module has been tested and prepared in a Virgin configuration, allowing it to be assigned to another vehicle using suitable diagnostic equipment.

Applications for ECU A6461500577

  • Mercedes-Benz Sprinter W906,
  • selected 209 CDI versions with 2.2 CDI engine,
  • commonly found in vehicles produced around 2007,
  • exact body version and engine code – to be verified.

Before purchasing, the references on the original ECU should be compared. Mercedes number A 646 150 05 77 and Bosch number 0 281 014 203 should match the markings on the module removed from the vehicle. The vehicle model, year of production or engine capacity alone are not sufficient for reliable part identification.

Common symptoms of a faulty engine ECU

  • engine does not start despite the starter motor operating correctly,
  • no diagnostic communication with the engine ECU,
  • engine stalls while driving or after reaching operating temperature,
  • irregular engine operation and reduced power,
  • no control of the injectors or fuel supply system,
  • recurring power supply, sensor or CAN communication faults.

Similar symptoms can also be caused by damaged wiring, loss of power supply, a short circuit in engine components or a CAN network problem. A complete vehicle diagnosis is recommended before replacing the ECU.

Programming and preparation of the Virgin module

The ECU is supplied as Virgin, meaning that it has been reset and prepared for assignment to the vehicle. After installation, adaptation, immobiliser synchronisation and the appropriate coding must be carried out using Star Diagnosis/Xentry.

  • Virgin configuration – data from the previous vehicle has been reset,
  • adaptation and coding are carried out after installation of the module,
  • vehicle equipment coding may also be required,
  • a stable power supply is required during programming.

If the original 0281014203 ECU still allows the data to be read, cloning may also be possible. In this case, the old module should be sent to us so that we can check whether its contents can be transferred. Cloning is not necessary when purchasing the Virgin version if the workshop can correctly perform the adaptation in the vehicle.

Frequently Asked Questions

Is ECU A6461500577 compatible with every Mercedes Sprinter W906?

No. The module is used in selected Sprinter W906 209 CDI versions. Compatibility should be confirmed by comparing the complete part numbers with those on the original ECU.

Is Bosch ECU 0 281 014 203 ready for installation?

The ECU is prepared as Virgin. After installation, it must be assigned, synchronised and coded in the vehicle using Star Diagnosis/Xentry.

Can the Mercedes 2.2 CDI CR4.20 engine ECU be cloned?

Cloning may be possible if the data from the original module can be read correctly. The old ECU must be sent to us first for inspection.

How can I check whether A 646 150 05 77 is compatible with my vehicle?

The safest method is to compare the Mercedes OEM number and Bosch number shown on the label of the original ECU. If in doubt, please send a photo of the entire label.

Will the vehicle start immediately after installing ECU 0281014203?

Immediate start-up should not be assumed. The Virgin ECU must first be correctly assigned to the vehicle, synchronised with the immobiliser and coded.
