Parking sensor not working

I would be very grateful.I did originally think it was just when the engine was warm, however I have since learned it appears to be entirely random. I recently bought myself a bmw 525d m sport 2005 model,howver the parking sensors do not work. I put the car in reverse, it makes a beep but they dont really work.

Working sensors do emit a faint clicking noise - You do not have to start the car to check this, just turn the ignition on and select reverse gear. Ultrasonic parking sensorsUltrasonic sensors bounce sound waves off obstacles, using the ‘echo’ time to indicate how far away they are.

Can the error code be reset without connecting the car to a board or do I need to replace the broke(? If you have no rear sensors it might imply bad coding, or bad towbar wiring as eluded to by SMC.

Please, one of the four reverse parking sensors of my car is missing and the LED display reverse backup radar is just making noise and not working to display rear distance of objects when am on reverse. One more problem - sensors have very narrow angle of working zone. I have a Ford Focus Ebony 2003 and my rear parking sensors have stopped working. My parking sensor which was factory supplied has stopped working and I get a fault message on the radio screenis this just my bad luck or is it a common fault?

Diagnosing and repairing a faulty parking aid sensor on an LR3, Range Rover Sport or Full Size. I say this because I made it 4,000 miles between repair visits to the Land Rover dealer. I mistakenly unplugged my rear bumper reverse sensor and now my dash chimes that I need to Service park assist.

I am having an issue with parking sensors on a 2008 FR-V EX.
