Posted May 23, 2022. time to have the front bumper off and check all the wiring and sensors, getting a fault code of 02069 - Front Parking Aid Sensors, open circuit, cleared off 23 seperate historic fault codes, drove it a good thirty miles and the only one to return is the parking assist.
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.Faulty sensors are the most common cause of the problem. It only makes sense that if your sensors aren't working, the problem might just be with the sensors themselves! To check them, make sure the engine is off and the parking system is turned on.
Start by inspecting the wiring harness that connects the sensors to the control module. Look for any signs of damage, such as frayed wires or loose connections. If any issues are found, repair or replace the affected wiring. Additionally, check the connections between the control module and the buzzer. Either scan with VAGCOM and it will tell you which sensor is faulty or With the ignition on (but no engine), engage reverse and jump out of the car after the constant beep. Put your ear close to each sensor and you should hear a clicking. The one that doesn't click is faulty. Once you replace the faulty sensor that should cure the fault. ojVBxC.
