Download Eeprom into BMW-Explorer, load Eeprom 95128/95256 and save Eeprom and write it back into the FEM / BDC.
Install the unit on the car in the reverse order of removal, and connect BMW-Explorer via OBD.The car probably will not respond to the key, do not get scared!
Connect to FEM, press “Reset mileage”, Explorer will propose to program the FEM / BDC, agree and wait for the programming to finish.
After successful programming, the program will write to you “Return the saved original Eeprom”, then remove FEM again and using programmer, return the previously read contents of EEprom 95128. Then you can install the unit back to the car.
Write BACKUP coding (CAFD) via OBD
Go into the FEM / BDC control unit with BMW-Explorer and press “reset mileage” button and after 3-5 seconds mileage will be successfully reset.
Install the instrument panel (KOMBI) with the edited new mileage
Sometimes it is possible that after the last manipulation the FEM / BDC will stop responding to the diagnostics, then you need to flash this EEprom into the unit and program the unit with Esys or ISTA-P and start the unit preparation from step 1.
