I have BMW FEM with water ingress.
Old Fem is damaged
How can I replace with used one?
Possible to replace it using vvdi2?
Yes, it is possible to replace with a used one.
Unlock fem old and save backup file fem. unlock fem new and write file backup (write vin/isn ecu)
The ISN from ECU, you need isn save from old and write to new. Try the new vvdi prog bosch ecu cable to not have to opening ECU .
eeprom 95128 or 95256 need read and write.
Xhorse VVDI2 it okey. You can replace fem to other fem (both new and used FEM. This is confirmed by Xhorse engineer). Its 15 min.
if not connect you must have new fem ordered or used fem write new key and DME ISN and 8HP reset ISN ! change VIN IN FEM !
with vvdi bmw, autohex or BMW Explorer.
