Goodnight,

I just bought AtohexII for locksmith, I have a BMW 318i year 2010, deleted the dump, wrote
another 318 dump and not respond, failed the CAS, buy a used, I can do it with the Autohex
II, read ISN of the ECU And write it in the CAS ???, what would be the procedure, sorry I'm
newbie and I'll just use Autohex.

Greetings friends.

you need to read isn from msv and write it to cas. you also need to make new key to cas, as you cannot connect to old cas. you may need to make cas downgrade if you have cas3 plus.

just go to dme cas isn and make sure you follow steps. it is really easy

Thank Very mouch, Tibibond...

dont forget to change CAS vin number,
and copy FA from FRM to CAS (be careful)
after that rerun program and code CAS
