Update
I took the car to Newcastle Audi and waited 90 at the showroom. I had no opportunity to speak with the technician. The service reception lady said it was ready and gave me the keys. I asked if it would need setting up with my acount and she said it would. To cut a long story short the MMI was even worse and would not boot up, she want and got the technician. After lots of messing about turning on and off the ignition and opening doors, I was told the battery would need to be disconnected overnight and I was sent on my way with a loan Q2. Most of an afternoon wasted and I still have to go back to collect my A3..
When I checked the car in I was told the fix was only temparory and may only last a couple of weeks
I decided to set the Q2 up with my account and set some radio favourites. This morning they were still set, maybe this Q2 has no problems, it's on version 4142. I'm not sure what my A3 is on
So tempted to reject my A3 as it is only 10 days old
