FYI: BMW FEM/BDC Coding/Programming with VVDI2 full kit 4.3.0 .

step 1:

read FEM/BDC coding via OBDII or on the bench
you’d better not close this window after starting this procedure
step 2:

open FEM/BDC shell, find out where the 95128/95256 chip is, read EEPROM dump via BDM programmer
load original EEPROM dump and save special EEPROM dump, write special EEPROM dump back to the 95128/95256 chip
restore FEM/BDC shell, provide -12v and connect it via OBD
step 3:

this operation requires connecting FEM/BDC on the bench, and make sure you finish step 1 ans step 2
provide +12v to FEM.BDC and connect it via OBD
step 4:

open FEM/BDC shell, write original EEPROM dump (read step 2) back to the 95128/95256 chip
restore FEM/BDC shell and connect it via OBD
step 5:

loading coding file (read step 1), write to FEM/BDC via OBDII, finish FEM/BDC programming

Attention please!!!

– You can directly backup/restore coding

– You have to pre-setup the FEM/BDC module before deleting/adding keys or resetting keys

– You’ll be told other tools need to be used first to program the FEM/BDC system, then setup FEM/BDC via VVDI2. It happens when you do FEM/BDC key learning, and you don’t have a working software version

– You’d better not close the VVDI2 interface when you pre-setup FEM/BDC

– You need do with 95128(FEM) or 95256(BDC) chip when pre-setup FEM/BDC

Note: there are two 8-pin chips; do not disassemble the wrong chip; better refer to the wiring diagram

– You must restore original EEPROM data, restore coding when pre-setup FEM/BDC. If you fail to restore coding or the remote cannot start or something wrong with the window (or other failures probably) after coding restore and FEM/BDC installation, please use other tools to do re-coding FEM/BDC

– Ask tech support @eobdii.fr for help, if the replay sounds continuously after supplying power to the FEM/BDC. Usually, it needs programming.
