6f68 and 6f67 DSC: No F-CAN message[ICM, 12E and 136]..Car has no ICM, someone installed X6 CAS and wrote car vin in it plus ISN. Car drives fine but dash is lit up. Tried coding it thing got worse more control unit with faults. Replaced DSC same problem.....Programmed car thing got worser. Got CAS files off 2007 thing got very worse. Need suggestions.
The normal steps for the replacement of CAS (when original CAS is dead)
1. Get a working CAS with valid key
2. Read DME ISN and write it to CAS
3. Restore FA from LM to CAS from FA manager
4. Change VIN for CAS from advanced option in CAS replacement
5. GO back to the main menu in software
6. Start again with coding/programing
7. DO coding for CAS
Make sure you have restore FA.
