This service provides a complete plug-and-play ECU replacement solution for BMW vehicles equipped with the Bosch ME17.2.9 engine control unit. This ECU is used on turbocharged BMW N20 and N26 4-cylinder engines and controls fuel injection, ignition timing, boost regulation, VANOS, and emissions-related functions.

ME17.2.9 units commonly fail due to corrupted flash memory, water intrusion, internal hardware faults, or unsuccessful tuning/programming attempts.

Using professional BDM-style bench programming tools, all operational data from your original ECU is extracted and cloned to your replacement ECU, including:

• Full EEPROM transfer

• Flash memory transfer

• ISN (immobilizer synchronisation)

• VIN

• Coding and software configuration

• Adaptation data when supported

Once cloned, the replacement ME17.2.9 ECU installs directly as a true plug-and-play module without requiring dealer coding or programming.
