This service provides a complete plug-and-play cloning solution for the Bosch ME5.2.2 engine control unit, used in a series of late 1990s and early 2000s BMW and Land Rover vehicles equipped with BMW’s M62 V8 engine family.

The ME5.2.2 ECU controls ignition, fuel injection, VANOS, throttle management, and emissions systems. Over time, these ECUs commonly fail due to heat, moisture exposure, corrupted EEPROM or flash memory, failed chip tuning attempts, or internal component aging.

Using professional BDM-style bench tools, we fully extract and clone all data from your original ME5.2.2 ECU to your replacement unit, including:

• EEPROM memory

• Flash memory

• Immobilizer / ISN data

• VIN

• Vehicle coding and configuration

• Adaptations when supported

Your replacement ECU becomes a true plug-and-play module, requiring no dealer programming or coding after installation.
