My wife has a 2019 Cayenne S, and I have a 2021 GTS inbound on a cargo ship. I am considering getting a PIWIS 3 in order to tweak a few settings and do some of my own maintenance. I can't find any good information about what code revision the PIWIS 3 will need to work with 2021. Does anyone here know, or does it just need to be a PIWIS III that works with 2020's (which does not make sense to me)?
