I know how to make key using CAS dflash and autohex, I made it many times, but I hoped new feature will do it without removing CAS, like it is with CAS 3+ in E series.
I have licence for online and with CAS 3+ I can make CAS firmware for key learning. Is CAS 4 another story? Can`t do it like CAS 3+ by OBD?!
Are you sure? You cant make CAS3+ key by OBD. Cas must be removed or atleast you must connect to cas pins directly in factory mode. Is there a tool that makes cas3+ 100% by obd? I have tried it and it fails. In all cases I have had to connect cas pins to AH to make key. Good thing is we need not read cas dump.
But again I may be wrong. Would be nice to know cas3+ can be done 100% obd.
Ive done many CAS3+ thru obd
it had failed only once or twice
good method is, before u downgrade it, update it from indiv progamming, usually to ZB that ends with 116
then downgrade, this method never fails.
