Stickman: It appears that the problem (it's not really a problem- more like a characteristic), is more about the Part Number/Software version) of the BCM in the car.
I've gotten access to an adaptation channel map (this is VCDS's equivalent to OBD11's Back-up file) for a MY17 Golf Alltrack (NAR model) which has a BCM with the PN/SW version 5Q0-937-087-
AA. This car has a perfectly normal adaptation channel list that can pretty-much be found on any previous BCM on a mk7 Golf
Your car has a BCM with the PN/SW ver 5Q0-937-087-
AN (NAR model) and it has the
new Parent-child associations.
So I'm guessing that the changes were made somewhere between the AA and AN version of the BCM - not sure where!!

PS: If anyone here has an adaptation channel map (preferably from VCDS) for a BCM (Central electrics module @ address hex09) with the PN/SW ver close to 5Q0-937-087-
AN and they are willing to share - I'd welcome a copy, please
