I have the HEX+CAN interface, just updated the software to VCDS release 18.91. Plugged into our new 2019 A4, went to Module 08 Auto HVAC, got the message that it’s an unsupported vehicle, with the adaptation box (among others) grayed out! Help!
Yep, B9 (and other MLB-II platform cars) have compatibility problems with the old HEX+CAN interfaces, as do various control modules in other late model cars, so we drew a line in the sand with 2019 models; they require a current interface.

I'm not sure why you think what I wrote could be mis-understood, but your re-statement is correct; all 2019 models require a current interface.I think that sentence could be misunderstood.
To my knowledge every car from the VAG gang that is model year 2019 is caterogical declared as not supported. No?
