Technical Information
- Manufacturer: Bosch
- Model: Citroën Xsara 2.0 HDi
- Product Codes: 0281010550
- Other Numbers: 9641608480, EDC15C2
Installation And Coding – Important
– The Unit Is Used And Is “Paired” With The Original Vehicle (VIN/PIN/Keys).
– Commissioning Options:
1) Cloning Data From The Old Unit (EEPROM/Flash) – After Cloning The Unit Is Plug And Play.
2) Virginization And Subsequent Initialization/Telecoding Via DiagBox (Or Online) + Key Adaptation.
– Recommended To Be Carried Out By A Specialist With PSA Service Equipment (DiagBox/Lexia/PP2000).
– Always Disconnect The Battery Before Removal/Installation And Follow The Manufacturer’s Procedure To Avoid Damaging The Unit.
Installation Recommendations
Before starting, make sure you have the correct part number. Disconnect the negative battery terminal and wait a few minutes to discharge residual power. Access the ECU from the engine bay or passenger footwell depending on vehicle specification, remove securing screws and unplug all connectors carefully—do not force or bend pins. Inspect and clean connector contacts before fitting the replacement. Refit the ECU in the original mounting position to avoid excessive vibration. After mechanical installation, perform cloning or coding as required (see Installation And Coding section). Verify all engine sensors and grounds are functioning to prevent immediate re-failure. Use proper static precautions and avoid working in wet conditions.
Why This Part Most Often Fails
- Moisture Ingress And Connector Corrosion: Water or condensation in connector areas leads to short circuits and intermittent faults.
- Electrical Spikes And Poor Battery/Charging System Health: Voltage surges or a failing alternator/battery can damage onboard electronics.
- Thermal Stress And Ageing: Repeated heating cycles and aging solder joints/components reduce lifespan over time.
- Improper Handling During Removal/Installation: Static discharge or incorrect connector handling can cause immediate failure.
- Immobilizer/Pairing Mismatch: A replacement unit that is not cloned or initialized will prevent engine start until properly paired or coded.
This ECU is commonly searched by its part number (0281010550) and reference number 9641608480. Suitable for workshops and experienced home mechanics who can perform or arrange proper cloning/coding. Purchase this unit to restore reliable engine management and eliminate error codes related to the original control unit.
