Finally recieved my vehicle back with new transfer case and the update.
Software is x1946. Not sure on head unit, but they had to update that again, after the bcm update
Recommendation for anyone getting it done, note down your engine hours from the menu before handover. And if anyone asks, service interval running time is 500hrs. This is because after the update they have to use the scan tool to enter this info (if you get "service due" notifications, its likely because they have not done this part, or done it incorrectly)
-Time until next service (so remember when your last service or purchase date was)
-Distance until next service
-Hours until next service.
This info is availble in the menu
New transfer case was again really stiff to change first up, but a couple of changes and it is feeling better.
No chimes when starting (how we used to wait for the 2 chimes, they do not happen now)
Battery charging appears to be much better. From my experience the previous profile would try to keep the battery around 85%, now looks to be fully charging. Still early days though
No wireless Android Auto
AC condenser leak not fixed yet, but there is a fix, they want to do it on the shop car first
PDC beeping at front still a random issue
Tire pressure sensors need more time I think (these had to be re added to vehicle after update)
At this moment other random head unit errors appear to have gone
Passenger air bag is now switchable (dont know why or how thats ok, but it is)
As mentioned, no longer any wheel speed details or additional info screen in offroad mode (i liked that screen).
I think that covers my update experiences
