XZBMW  BMW E64 CAS3 flash failed
Hi,

I'm currently facing a big problem, a guy tried to add a key to my car with autel im508 tool, which as I understood tried to downgrade the CAS' software in order to exploit a weakness permiting to add keys.

Downgrade flashing encountered an error mid way, and now communication with the CAS is impossible.

As I understand it can be stuck in programming mode or something else. I've tried resetting ELV counter (ast this is the only error the car was showing) but no luck. When I try to read the CAS Ecu with Carly / bimmer-tool (I don't have my PC with inpa / ista with me), it says that the control unit is not responsive.

What can I do to unlock my situation?

Car is a 2007 BMW E64 650i, without comfort access.

Thank you!

Update: the "key maker" owned up and paid a real professional to put everything back in order. As the car wasn't in my hands I wasn't able to test via winkfp.

Thanks for your help people! Really appreciate it smile
