Write the 95128/85256 into the new EEPROM data using BMW-FEM adapter, then solder it back to the FEM computer board. Then reinstall the FEM computer into the computer, supply power to the vehicle. Then click on “OK”.

Will upgraded ECU, please ensure the vehicle battery voltage is not lower than 13.0V during the upgrade, the process will take 10-30mins, please wait patiently.
