The EEPROM data of CAS1 – CAS4 can be renew. First load the EEPROM data from the other car, then modify the car frequency, VIN, ISN code and other information to generate new EEPROM data. So that it can solve the problem that the CAS EEPROM data lost or the CAS module damage and the EEPROM data can’t be read out and the CAS module needs to be changed.

Step 1:
Prepare the EEPRON data for the corresponding chip model and copy the data to the APP path: “:/ Atmatch/bmw/CAS4/CAS_Renew’, then select the corresponding EEPROM file for parameter calculation.

Step 5:
Use professional equipment to clear the trouble codes of the vehicle.

The original car key is invalid and you need to relearn the new key to start the car.
