Park assist beeper doesn't sound and screen display doesn't indicate when approaching an object near bumper sensors.

I don't know if you still need help or not, but I just replaced my sensor this weekend. It was the passenger side, #2 from the edge. The sensor cost me about $200 but don't forget to get the clip for it if yours is broken. I had to unscrew the plastic panels from underneath the car. The whole panels are a major pain to remove so I loosened up the front screw sets only of the panel on the side, then the front and middle row of the center panel. That allowed me to pull it down enough to get my hand in and reach the sensor. From that point on, I had to do the whole thing blindly. THe clip slide from the side to the center of the car, then you push the sensor out, then unplug it (it had a little plastic thing you have to push down to unpulg it. Then put the new sensor in (insert if from the outside), plug the wire in, then "clip it" (slide it center to outside). The sensor ir parallel to the ground and the wire is from the outside.
Very complicated, I know. It took me about 2 hours.
Then screw the panels back in and you're in business.
The only issue left to figure out for me, is on the screen, top left, the lines showing up on that tiny car thing, on the side I replaced afre now yellow. But all works well.
I'm gonna google it and see how to "fix" that.
Hope this helps.
