Hi @Steve Q and @Jonnyb537
New member here. I, too, have a 2022 A3 diesel. On 31/12/23, the touch screen remained blank. An hour earlier, I had driven 75 miles without problem. I tried the full extent of my knowledge of car electronics, I switched the car off and then back on again. Still blank screen. Drove to lunchtime restaurant without the screen. Two hours later, return journey, it worked again and has done ever since. Car has 7,600 miles on the clock.
I bought the car from new. I'm reluctant to take the car back to the Dealer until I know a little more. Google shows this to be a common problem but doesn't show much about a robust fix. Also, is this black and white a warranty issue or should I expect to have to handover my blank chequebook?
Thanks in advance for any help and advice from fellow, frustrated owners.
