I explain the history: I wen to a customer who needs to change egs in a x5 e70 3.0d 231hp ecc16. I used AVDI to do the operation, all seems to go well, until I tried to start the vehicle. In DDE EWS tampering (avdi changed DDE ISN in CAS), well, tried to change manually the ISN, and I think avdi corrupted the first lines of the eeprom data. I see duplicated 4 byte isn (EGS+ DDE ISN) and copied to another memory data. Well, I tried to align ews and dde and the ista program tells me is impossible to do, data telegram error, so now I'm pretty sure data is corrupted. I only want to make again start the car, because I bought CGDI to reset egs data and pair ir again. I put all data I have:

BMW CAS part nr: 61359147190-01 5WK4 9514OBR 2073060167

CAS3+ unencrypted version

ECU Part NR: DDE7809944 0281015129 EDC16CP35 2 byte long ISN

ORIGINAL ECU ISN NUMBER: D63B
USED EGS ISN NUMBER: 1A05 6778
DATA PUT IN CAS3: EGS-ISN - 1A056778 - DME-ISN: 6778

I attach 0L15Y eeprom data modified by avdi (I know, my fault because of I didn't make a backup before)

The main problem is I can't sync DDE -> CAS

DTC error in DDE is: 4a41: DDE-EWS: interface error
Also AVDI tells me in DME-EWS SYNC STATUS: bad synchronization, mismatched ISNs between CAS and DME

Many thanks for your time and effort.

AVDI delete 32bits DDE ISN.921072

AVDI delete 32bits DDE ISN.

I don't think your CAS supports something like this
