I didnt know that! Thanks Steve.
Anyway, it has been rectified. The car went through numerous software updates, the technician phoned us to say our system has been updated so you will see minor changes but the B&O system issue has not been cured. It will need further investigation but it mostly likely will be the main control unit for the MMI system (£2,500 in total). My wife and I were gobsmacked. He mentioned that the master technician has seen a few of these cars do the same as ours and overnight when the car has been shut down for a while, restart car in the morning, the system settings appear and its fixed so all we had to do was keep our fingers crossed.
We left the dealership, turned the car on, the settings appeared and the B&O system is now working. Amazing!!!
Work was carried our at Wolverhampton Audi 🙂
