Note: when you activate BMW data modification and verification authorization after purchasing the license from your dealer. Make sure you have downloaded CGDI BMW software before operation.
-Supports modifying the ISN, VIN and frequency in the CAS data
-Supports modifying the ISN, VIN in ECU data incl. N13, N20, N55 and B38
The corresponding data type must be manually selected to modify, otherwise an error will be reported.
2.How to know whether CAS data is encrypted?
Use CG Pro 9S12 to read CAS data (CGDI BMW can read CAS4 CAS4+ data)
CAS1, CAS2, CAS3, CAS4 these CAS data is not encrypted, the CAS ISN and ECU ISN are the same
CAS3+ and CAS4+data is encrypted
3.How to replace CAS data?
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 the frequency of the CAS data of car B, VIN and ISN to be the same as car A.
Remember to add key again.
->>Change the VIN and CAS ISN, click “Save data”, then load data
4.Modify CAS3+/CAS4+ data
When load data for CAS3+ or CAS4+, when it prompt that the data is encrypted, click “No” and it will show the CAS ISN. Click “YES” will show ECU ISN
You will be prompted to put the key of the original car into the CGDI coil. At this point, the car key of the data itself should be put in. (Car A data puts car A key, Care B data puts car B key).
Or enter the corresponding key synchronization code (if the key synchronization code is entered incorrectly and the ECU ISN appears incorrectly).
5.How to replace encrypted CAS data?
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 the ECU ISN, so you need to read the ECU ISN of the car A, then write into the CAS of Car B, and then change the data as car A at the same frequency and the VIN.
That is, after loading the encrypted data of car B, click “No” to show you the CAS ISN of car B, and then write the ECU ISN of Car A to the location of CAS ISN. Then modify frequency is the same as car A. Save data, write to car A.
Remember to add key again.
6.Modify N13/N20/N55/B38 data:
Load data, cannot not modify the frequency, other can be modified normally. After modification, go to save the data.
Load the data in to check if the data is incorrect
1.An error “File verification failed” will be reported when the loaded data and selected data type are inconsistent.
2.An error “Incorrect file type” will be reported when loaded flash data.
