parking sensors question

Hi
the parking sensors on my newly bought w163 ml 270 dont work, is there any way of testing the sensors as im told that one faulty one can cause them not to work.
Thanks in advance

Needs connecting to STAR to check each sensor.

What are the symptoms? Have they ever worked?

Hi
Only have the car 2 weeks, were not working when I bought it, im getting 2 red leds each side of front display.
Was hoping I might be able to test each sensor with a multimeter than have to go to to main dealer.

if you get right up close with your ear you can hear the good ones tick on a repeated pulse . car in reverse with ign on . if you hear a one that's ticking , remove the lot and try them one at a time on that part of the loom . or if youre lucky they all bar one might tick and you've found the culprit

I have the same problem but do you have to take the front bumper off to get to them if so
Is it an easy job?
I knot the duff sensor is just above the fog light

Finally got around to this, bought some sensors from ebay, the only ones that can be changed without removing the bumper is the 2 front ones on the side
