Beep warning when in reverse

Hi there
My car is equipped with a warning (Beep) Achtung

when you are to close to any object when you are in reverse.
The system has worked Ok until now.
When I put the gear in reverse the beeping starts without any objects behind the car.
After a few seconds, or if You take the gear inti neutral and back in reverse, the beeping stops.
But....
When You back up against another car the system don´t work.
No beeping.
Anybody who knows what to do ??
Traurig

All the best
Lasse

Hi Lasse,

one of your ultrasonic sensors is probably broken. Use the Testbook to find out which one it is.

Cheers, Tom

Hi Tom
Do You know how to remove the sensors ?
I checked under the car and it looked like I have to do it from the outside.
You could hardly reach them with one hand.
If You only know how to do it I guess it´s simple. Fragezeichen

Some times the sensor realy fail - Often it is only the cabling failing.
If you put in R gear with ignition on and engine not running you should feel some kind of vibration at each sensor - if not you know where to look first.

Sorrowly i don't really know how to get them out.. just telling you what I have read in the German sector...

Hi again
I just heard that to remove the warningsensors You first have to remove the whole bumperassembly.
Then You can check the wiring and eventually remove and change the sensors.

Is it hard to remove the rear bumper assy ?

No, the removement can be done by yourself easily.
More easy it would be to check the car via testbook.

The kind of vibration at each sensor, as described from Transalper, is also hear- and feelable when one sensor is broken. It took me a lot of time to find this out. Also trying to remove one of the four sensors, to determine the defect one, does not help. If there are three working sensors and one missing, you also got the beep.

Good luck, Tom
