Use CG pro to read CAS data (CGDI BMW can read CAS4/CAS4+ data)
The CAS data is not encrypted, the CAS ISN and ECU ISN are the same.
The CAS data of car A is broken. You can find car B CAS data same model as car A. We only need to change data of the frequency of the CAS data of car B, VIN and ISN to be the same as car A.
Remember to add key again.
Select data type: CAS3
change/modify VIN and CAS ISN
The current data is CAS for encrypted version data. Do you need to decrypt the ISN?
Click “Yes” will show you ECU ISN
Car A CAS data is broken, you can find car B CAS data same model as car A. You need the ECU ISN of car A, because the encrypted data CAS ISN is not consistent with car B, then change the data as car A at the same frequency and the VIN.
Save data, write it to car A. Remember to add key again.
Press not to decrypt the ISN
Select remote frequency: 868MHz
Manually modify/change VIN and paste DME ISN here
You can load the data and the wrong place will show up
Supports CAS4+ FEM BDC version and calculates a third data based on two data sets.
