So please keep this tread for programming help. First of all, a PIWIS II and a Piwis III do the same things, only the three can do newer cars, 2018 and on, where as the two is limited to the 2017 and earlier models.

My background, I do not work for Porsche or have I ever used a dealer unit. What I learned, I learned from playing with the units. I had purchased a flooded 2013 Panamera, ...
