Hello, I am working on a 2007 BMW X5. The vehicle sat for a few months, the battery died. Tried to boost it, the vehicle recognizes the original key, buttons work, dash comes on. No start. No crank.

Did a scan with Autel IM608 says "Car Access System (CAS), Engine Start Operation."

Tried to do Cas Update, update failed.
Tried to do ECU Repair, repair failed.

I've read the Eeprom and Flash, could someone tell me if they have dealt with this?
Is it a problem in the data or a mechanical?

Under CAS "Live Data" did you check the "Terminals" status? Particularly 50E and 50L when attempting to start the car.
