Just by way of an update, my car was back in the garage for 2 days trying to resolve the software related issues. As soon as I left the garage the car continued to do OTA updates (despite it going in to be fully updated and tested), which was pretty frustrating!
The climate sync issue was not resolved, although through a load of testing it seems to stay on if you leave and re-enter the car after a short period, but after an hour it defaults to being off. I am not sure if it works when you are signed in as a guest...something I would probably test if I wasn't sick to the back teeth of it!
VW were/are adamant they fixed it, so are either they are stalling or just dont know what they are doing!
I also continue to have Apple Car play issues where either the phone wont automatically connect or i get blank screens when navigating to the car play specific menu.
I have now been asked to send video evidence to the manager so they can take it up with VW UK directly...
I do find it very odd that they have not come across the climate sync issue before. As far as I can tell it doesnt work on any Golf 8, not just GTI's...clearly not a a game breaking bug, and one I am sure will be sorted eventually, but after the issues I have had so far, I've come too far with them not to continue!
The software saga continues...
