parking sensor working incorrectly (strangely)
 

When I engage reverse gear I notice the button on the dash (P) activates and loud unstoppable noise is coming but as I come closely to something parking sensors give their working sounds that I'm coming close to something,I mean they are working,sometimes it's vice versa,so what should I do guys? :(

see here.

you have two different sounds? one is unstoppable, and the other one for the obstacle?

can you describe in detail what is happening, please?

Today I checked all the sensors,they are all clicking and working,then I took off the number platr and here it goes! I think front middle 2 sensors are sensing number plate and because of that comes this annoying beep noise,after I put the number plate back it started beeping again,sometimes not,so I think basically it's because of number plate... don't know really how to solve the problem...

^ move or remove the number plate..?

do you have CCFL angel eyes installed in your car, by any chance? they can interfere with PDC

what is ccfl? i've oem factory headlights with angel eyes (yellow)

CCFL - Cold Cathode Fluorescent Light, an aftermarket angel eye retrofit that emmits electromagnetic field that interferes with the PDC function.

does not apply to you, as you have the factory angel eyes...

Please tell us what car you have, what year and so forth. Thanks.
