Is there any possibility to repair this CAS on bench witch AutohexII or maybe can somebody check attached files from this CAS ?

Have you any communication with CAS??
Engine cranking or no?
P.S
Your ISN is EEC9 and VIN WBANS71070CP29454

I know all this info. Car crank and run without problem . I have communication with CAS but can't update it with any tool ( WinKFP , ISTA-P , AutohexII , Abritus ) because eeprom checksum error. The problem is after any battery disconection I must syncronize CAS with DDE. For me that is no problem but for the customer it is.

Dear Friend.
If the CAS information is corrupt, you can replace good information from another CAS, then you have to change the corresponding ISN in the CAS and program the key.

just use eeprom from normal working CAS2, and put ur ISN and keys there

you can save the key data from option 1 key learning ,use the the key file to program new key.
