Problem:
failed during make add key BMW X2 with Autel IM508S and Godiag BDC/FEM test platform module.
usually does not have a problem before.
but now failed and can not program.
failed -> restore eeprom automatically -> shows mismatch versions.
can not read BCD with power, but first time read without power.
how can I repair BDC and add key again?
Solution:
When you chose Smart selection, Autel will automatically back up coding and original eeprom file. You can either put everything back in the car and restore or find the original eeprom file and restore. It can be very difficult to find the file though.
Also very important BDC has a different Eeprom chip. So make sure you read the right one.
Don’t panic just go manually. Go by system into fem key learning. Exit Smart mode, go by system- fem- key learning.
Updated:
We got it fixed manually through IMMO- BMW- By System- IMMO- FEM- Key operation- Key learning- preprocess learning.
