Shame, though I have a RossTech HEX-USB+CAN lead along with VCDS on my laptop. Whilst it doesn't cover everything on my 2017 Tiguan it does enough so far for my needs. Diagnosed and replaced the glow plug module last year. This spring I installed a new battery, after the old one seemed to be heading south, and programmed that to the car (not sure how necessary that is but lots of minor, yet persistent, electrical issues in logs disappeared as a result of the battery change).
