Hello,

I have a Kess V2 reworked on order and would like to read / write Audi S5 3.0 TFSI SIMOS 8.4 ECU,
ive seen some places say it needs to be unlocked before and some say the Kess 5.017 will do it straight away. Does it need unlocking? And if so how do you do it?

Thanks for the help!

SIMOS 8.4 need to unlock KESS V2 through a special adapter or KTAG, and the new KESS V3 with Ksuite 3.0 software up, does not need unlocking because it does virtual service read
