FAULTY REVERSING SENSORS , INITIAL 3 SEC BEEP WHEN REVERSE IS SELECTED THEN NO SIGNAL WHILST REVERSEING.

Maybe you can't. That is probably not a fault and nothing to do with the parking sensors. Many vehicles have a safety feature to alert anyone behind you that you are reversing. It operates from a switch when you select reverse gear. There have been tragic tales of children and adults run over on home driveways. The beep alarm helps to prevent these accidents. This scenario applies if it is louder outside the vehicle than it is inside the vehicle. If the beeping is inside only, there is indeed a fault. The only way to find which sensors is faulty is to have an auto electrician connect a pro grade scan tool computer and check the parking sensors.

Does you shift indicator point to "R" when in reverse. The reverse light are switched on by the selector shaft position sensor built into the Parp/Neutral Safety Switch. It may be bad or just out of adjustment.

the beep is a warning of system failure the usual problem is water in the sensors, to test the sensors engage reverse with ign. on and put your ear close to each sensor in turn you should hear a faint ticking from the good sensors, nothing from the faulty ones, the wiring behind the bumper is also prone to burning on the exhaust. hope this helps.

I have found the beeper wired into the reverse lights and if you just find the beeper and cut off the wire and cap it you should be fine and no more beep.

No, the rear sensing system won't signal if you are in any gear except reverse. The wiring for the module is connected so that it turns on when you put the car in reverse. (This assumes the sensors haven't failed. If they are dirty, they can sometimes signal when an object isn't there.) Some newer cars have blind spot monitors that indicate an object approaching from behind and to the side; these don't indicate an object directly behind the car.

I hope this helps.

The sensors are sensing the tow bar, either remove it or disable the back up sensors.

They have most likely painted over the sensors in the rear bumper or the module has fialed or the sensors are not plugged, one other slim posibility is the siren in the module is faulty.

There is few options.First-reverse switch not working.How to check-switch ign. ON,select Reverse and check reverse lights at back.If not-change switch.If O.K. go to step two: Disconect reverse sensors next to a bumper and check for resistance/any one/,because all sensors are conected in serie.If there is not resistance check all sensors one by one to find a wrong one.And last one-check "beep" speaker

I have an Audi A4 with factory fitted parking sensors that emit a long beep when reverse gear is selected (so this tells me I have a fault) where do I find the control box to remove a sensor at a time to find which one or more are faulty?

hi pam from the uk ! the reverse signal/beep can be disconnected however there are different methods of how the beep is operated ? in uk some cars have the reverse light bulbs that are also a beep sounder when reverse engaged ? orthe sounder may be a seperate sounder unit at the rear located either in boot? or behind rear fender? or as you mention beep sounds inside boot area?? the sounder may be hidden behind one of the side panels in boot? if you put ignition on and select reverse then try finding beep location? if/when you find it? just disconnect wirefrom sounder and make sure reverse light/s still remain on tape up the wire disconnected out of way? if it is the bulbs that bleep? you will have to remove and fit an ordinary type bulb usually a flasher/ indicator bulb? hope this is of help and inspires you to diy ? best wishes
