Park Sensor problem


I fitted a new park sensor (mid left rear) yesterday and PDC still not working! (still getting the 5 second beep when I put into reverse)

I diagnosed the faulty one by putting the car into reverse (ignition on, engine off) and listening for the "clicking" sound at each of the sensors. Now all are "clicking"

Can anyone advise what I should do next?

the next thing you should do is plug in a vag com and see what faults are there, you may have one that is clicking but not hearing the echo. you will be able to see in measured value block 1 which sensor is not working correctly, alternatively try and catch a technician at a dealer and offer hime a tenna to plug it in for you if he is free?
