Hello mates, i have issue after damaged DDE replacement. I reset ISN in CAS only and after that the car was perfect. They drive the car 1000km without any issues. After that replace the battery and the car wont shift gear. Starts and record " EGS immobilizer in transmission control disables.
Any idea for next step? And why it happend after 2 weeks and battery replacement?

it was egs lost ews sync after battery replacement, please sync egs again and disconnect battery negtive and check if loosing sync again, if yes please contact tech support they will help you.

I will try and report, thank you

I think you better off not touching the CAS ISN when replacing the DME. It is easier change it in DME and avoid transmission issues.

Please do the following:
Don’t leave the ISN in cas like this: 00 00 xx xx
The first 2 hex numbers in isn should not be zeros.
If you left them zeros you will always lose the sync after disconnecting the battery.

I just use CAS DME ISN manager. i dont know how looks ISN in CAS. Copy isn from the new DDE and load in CAS. how to protect myself and what to do to prevent it from happening again?

- Fill two random hex numbers in the CAS ISN, example 56 44 XX YY, where XX YY are the DDE ISN
- Reset the EGS EWS from ISN Manager again.
This will solve your issue for good
