I upgraded my 2005 A8's parking sensor ECU in February to the C revision that shows the display on the MMI screen. It worked fine since then until today, when I noticed that the display no longer appeared whenever I used Reverse gear or pushed the button on the dash
I've scanned the ECU and there's no DTCs and the coding hasn't changed somehow, so I'm puzzled why it no longer works!
Code:
Address 76: Park Assist Labels: 4E0-910-283.lbl

Anyone have any idea of any tests to try or settings to check please?
