Most of you may have a question :
Now Xhorse VVDI2 VAG id48 is not ready. so i can’t add key passat b6 or any other vag key with id48 chip?
It programs passat b6 b7 or other id48 cars by obd?
Not all possible over obd. Some need read out bcm2, some of them need read out with programmer, like vvdi prog or other.
Some newer Passat with ECU EDC17, if you have condor key cutting machine and with working key,
you can directly do by OBD get 6 cs and use working key get the 7th bytes cs.
If without condor machine , you should remove the comfort module get the eeprom,unencrypt the cs and pin from EDC17.
Some old model passat with old ECU edc16 ,yes you can by OBD but you must have working key for calculation last two CS No. No need condor authorization for this , condor authorization is only for calculation PIN CS from edc17.
Customer working experience:
Vvdi2 does passat by obd but not on 1.6tdi with pcr, I have done 2012 caddy by obd with it, f10 key by read mcu in cas4 with vvdi prog and made key with vvdi2 , I have made keys also with the key tool, I have done passat from ccm also and some other vag also.
Full key programming car list which vvdi2 full does by obd.
