Here I want to share the guide on how to use BMW E/F scanner II to read out BMW CAS1-CAS3+ ISN code.

And for more information please visit BMW E/F Scanner  blog


BMW E/F Scanner Interface:
V2018.12 BMW E/F Scanner II Full Version (Recommend)
2013.07V E/F SCANNER For BMW

The BMW Explorer program has a possibility of reading a code of synchronization of ISN (all versions of CAS1 CAS2 CAS3 CAS3+).
Go to the CAS control unit, “Additional functions”, “Reading ISN”
In the opened window ISN will be displayed.
If the machine is equipped with the EWS3 system where 2 bytes of the constant part and the change are used, it will be displayed in the window 2 bytes of ISN DME (the upper 3 windows will be empty), if necessary they can be changed.

If the machine uses the EWS4 system, then 16 bytes of constant synchronization are used and there is no variable part.
Also after 2006, CAS3 uses an anti-theft code for EGS
If there is an EWS3 system in the car, then this code is the same with the engine control unit, if the machine already has an EWS4 system, then EGS uses separate 2 bytes
The program is in place of the engine ISN, it will display the gearbox code .. as in the picture below
