  • Rear parking sensor fault

    My rear parking sensors do not seem to be working when I first put the car in reverse it flashes up on the screen saying parking assist system fault along with my service light but when I put into neutral and then reverse again the service light goes out. Also its doesn't beep at all when in reverse I have cleaned the rear bumper and still hasn't done the trick. Any info or tips would be greatly appreciated

    It's possible with the colder, wetter weather, that one (or more) of the sensors has been affected. I seem to recall something about drying them out one by one, ensuring the connections are also dry, or maybe one of the sensors has failed and needs replacing. I don't have them on mine, but hopefully someone who has had a similar issue can help more. Have a quick search through the forum too, as there should be a few posts that could give you a bit more info.

      I'm hoping at the weekend when it's light I will have a look at connections etc may also give them a dry no harm in trying. Thanks I have looked at the other convos on here and ppl saying possibly one sensor gone and effect the whole lot.

        Had this issue few months ago, unfortunatly couldn’t find the problem myself. (Tried cleaning the sensor, checked the cables, unplugged the sensors ect.)
        In the end, I got it replaced and cost me €130..
