I have owned my a4 for 6 months, the other day it won’t let me go into my car settings. It displays on the screen “ the car system settings are not available” I’ve tried  a factory reset with no luck.

Hello Connor,

If this were mine, I would simply be booking it in at the dealer and getting it sorted. You really shouldn’t have to concern yourself with why it isn’t working, and any degree of ‘DIY fiddling’ may just result in affecting your warranty. 

Kind regards,

Gareth.
