For demo purposes I disconnected one sensor.
This results in no display on the MMI, flashing parking sensor button and no functionality.
So, pop the car in R, the parking sensor button will flash, there will be no display, go round the car and listen. Use your phone if your struggling to hear anything, it shows up better on a recording.
I’ve done a billy basic video. Don’t judge. 😄
