2005 955 Front & Rear Parking Sensors

[acer54]

My front and rear parking sensors always show the first two red bars (from left to right) without any audible warning, the lights go out once I reach 10 mph and when I go below this speed they come on again.
I've also drove right up to my garage door (2-3 inches from the door) and no change in the sensor lights on the dash and no audible warning either - has anyone else experienced the same problem and if so what was the fix?

Hi, Yes I had this problem on my rear sensors and found there was a plug behind the bumper that was not good pin condition. I pulled it apart and cleaned and sprayed WD40 then re plugged and now it's working. You have to take off the rest bumper. There is also the same behind the front bumper with the plug being on the right hand side as you stand in front of the vehicle looking at it.

Thanks, it's in for some work on the 8th April, I'll have it checked then.
