This service provides a complete plug-and-play ECU replacement solution for BMW vehicles equipped with the Bosch ME17.2 engine control unit. These ECUs are found in select N52/N51 applications and are responsible for managing ignition, fuel control, VANOS, emissions subsystems, and safety-critical functions. Failures often occur due to internal hardware faults, water intrusion, corrupted EEPROM or flash memory, or unsuccessful previous programming attempts.

Using bench programming tools, your original ECU’s critical data is extracted and cloned to the replacement unit. This includes:

• Full EEPROM transfer

• Flash memory transfer

• ISN (immobilizer) sync

• VIN transfer

• Coding and configuration transfer

• Adaptations when supported

Once completed, the replacement ECU will function exactly like the original unit and install as a true plug-and-play part with no dealer programming required.
