BMW E90 M47 CAS Eeprom Corrupt

[korrni]

Hello, would you help me resync the immo to a BMW E90?
The 4A63 error code is always present, although I tried to resync the immo for several times.
I read the CAS eeprom and flash, and also the DDE eeprom.
Thank you, guys!

you cleaned the cas nicely, only the VIN and the keys were left

Hello and thank you for your answer. Actually the car had the battery exhausted and when the customer brought another battery, the car didn’t start. I didn’t change anything in any of the readings.

Yeah, I know, I thought there is somehow a way to reconstruct eeprom data.

For help need correct dump.
Because with this just nothing.

I guess I'll just have to buy a new CAS module if there is no chance in reconstructing the eeprom data.
