Parking sensors

[Schbrenk]

I have a fault on the front and rear parking sensors none of which are working, the red light is on in the roof console ,when I put the car in reverse I get a tone. Lasting a few seconds but that's it , any ideas or is it a trip to the main dealer .? Any help greatly appreciated

Paul, first of all, get somebody to listen very closely to the sensors. They should be ticking. You will need to have your ear right over the sensor to detect the ticking noise. The front ones all the time, the rear ones when reverse is selected.

 

There are, if I recall two separate modules, one for front and one for rear so it must surely be something in common rather than both modules failing at the same time.

Sorry pressed `post` before finishing message.

I also have the red light and tone when in reverse.

The front parking aid works well.

the best way to test the sensors is with a mechanics stethoscope about 5 ponds on eBay, if the sensors are all working you will here a distinct rapid clocking noise from each one when forward or reverse is sected.

 

On my 2005 2.7 I have a duel module in the boot that  has plugs for front and back.

 

In my case the red overhead warning light is on, I have a single front sensor not working, but the rears click but do not work, I am trying to find out...

If one front sensor will knock the whole system out (front and rear)

if you can change out the front outside sensors without removing the front bumper.

 

If you live in kent we could meet up and try to sort them out.

I have a spare loom and can test sensors by plugging into my car
