Question: Can I do CAS 3 ++ ista-p by vvdi prog and vvdi2? I have a one operating KEY (keyless)
Answer: Yes. it’s easy. about how to add a new key, there are some on youtube.
Here is suggestion from the experienced users.
Tony Curran:
Pretty easy, takes around 10 minutes after downgrading cas
All obd with vvdi2
Arturs Bedre:
Strongly suggest You take out cas & do this on table. Read out eeprom and make key with eeprom data …
Curtis C J Perry:
I’d do this bench. It’s so much safer (downgrading can corrupt flash data) and you have the benefit of having the Immo data for new keys in the future. Creating a backup of EEPROM and Flash is crucial IMO
Andy James:
Yes, take out cas and read eeprom with vvdi prog. You can get Isn from working key, then do file make key with the Isn and your done
No downgrade needed!
