F13 CAS4 unknown frequency
Hi guys,

After OBD циLoск of F13 CAS4, I am unable to add key as frequency is shown as unknown. Anyway to solve?

I'm thinking need to edit in d-flash.

Autohex2, although I'm not sure if the issue was there before циLoск. I will remove the CAS  and inspect.

RE: F13 CAS4 unknown frequency
After writing the modifed D-flash to a 2nd CAS of the same рдят number, the issue still remains. Both Autohex and Autel report frequency invalid.
