Allscanner VCX-Plus is a third party system and is not PIWIS, although they claim they have similar capabilities (unconfirmed).

I have the same questions on the Porsche Piwis 2 , i have post in another thread. Then I emailed the saler. Update Piwis Tester II clone will adds the models & features, like Macan wiring diagram, service plan etc. Update is not cheap, LOL. Not sure if it is able to reset the electronic parking brake for service, you know, they sale products but not test cars. Good it comes with 1 year warranty.
