I had exactly the same problem,fault showing right rear inner sensor,I changed the sensor and the parking assist module but still had the same problem.it turned out to be the boot lead harness part number C2Z19978 they break down overtime with opening and closing the boot,it destroys the coaxial cable for the camera but shows up as a sensor and parking assist module fault Hope this helps

That Lr2 is handy to have. I find the towbar works fine as a parking sensor . . .

Boot harness cable ,replaced mine cured problem .all worked again Wires break over time, opening and closing boot

Hello, thanks for the video, I have parking transmitter problems when I turn on the car, the signal is short and then wide away. What were your suggestions for this problem? Thank you

Hi so mine is doing the exact same thing. Now I've plugged the snap on and it's thrown back all the parking sensors. I changed the park assist module and still the same. Bit on a dead end at the moment 😅

Thx for the upload pal, mine doing exactly the same...video helped with diagnosis

already done new cable on mine... still not working.... will be module ... as it just bleeps on mine....

Did you ever replace that? I've the same issue with the same sensor and bought a replacement but can't find many walkthroughs on how to get in at them!
