250 Intermittent parking sensors

  1. As above really.

    Most of the time they don't work, then like magic they work.

    How do you check which sensor works and which doesn't?

    Regards
     
  2. Let someone hold their hand for 1 of the sensors?
     
  3. It doesn't even bleep when I put it in gear?!
     
  4. I saw this on a FB through

    They should "tick" if they work (apparently). Go to the pre-ignition stage (i.e. don't start the car), whack it in reverse and listen to each sensor

    Mine are intermittent as much as I get the "check parking sensor" message, but they always seem to work so i figure it's dirt or something
     
  5. This still doesn't work.

    Is there a fuse for this?

    Can you check on clip?
     
  6. No fuse, but clip can identify which sensors packed up, their wired series so if one goes they all stop working
     
  7. hiya
    i had the same problem. Most of the time they didnt work.
    Took the car to a motor electrician and they rigged it up to a laptop which had the correct software and was able to identify which sensor was not working.
    I checked the sensor in question and found the the connection clip on the loom was damaged. Found a clip from ebay and wired it in and all sensors work now.
    if its not a clip then its a sensor not working.

    Hope this helps
     
  8. It's so tight you can't even see Wiring lol

    How did you see which one?
