🌖 Audi A6 C6 Parking Sensors Not Working

I have a a6 c6 2007 with front and rear parking sensors. And none of them are working when in reverae gear no sonar beeps. I get these 2 parking sensor faults that I have attached to the thread. I wanted to try disconnecting front sensors and see if rear ones would work and vica versa. mO6a.
