2005 Porsche Cayenne, read CS/PIN, and add key done fully OBD2 with Autel IM608.
Done in about 8 minutes since it took a bit to read the CS data. It is just an old Kessy module.
I have quite a bit of experience programming Volkswagens, and select Audi models with the older Advanced Diagnostics products. That being said, I am completely blown away by the capability of this tool on the daily!
