    Sorry if this has been brought up before but I couldn't find it anywhere...

    When it rains one of my front parking sensors beeps like crazy every time i stop, which drives me nuts!

    Question 1, are they easy to remove to take a look at?
    Question 2, Can i do something to it to stop it happening again or do I have to buy a replacement?!

    Mine do this as well. I think its because rain water runs off the bonnet and down the bumper

    Also, mine false trigger when pulling up behind newer Ford cars/vans when stopping at junctions/traffic lights etc.

    I did think that, but then it's only ever the same one. None of the others have ever done the same.

    I've also had the false trigger, which is far less often so not as annoying. Must be a clash of the frequencies

    I've been getting false triggers in traffic but Park Pilot isn't showing which sensor has alarmed. I'll keep an eye out on which car type is in front/behind next time

    Had this too but hadn’t put the Ford into the equation, will need to pay attention when it happens again.
     
  6. check out this thread from back in the day.

    Renault and Ford both seems to cause issues.

    My parking sensors on my Leon work perfectly all the time. However my Mum as harking sensors on her Ford and whenever it rains they go really buggy. It seems water seems to get into the sensor and makes it malfunction. Might be worth removing them and making sure they're water tight.

    It no longer happens just when it's raining now, it happens every time I stop. I've had to turn off the option to have it come on automatically as it's so annoying having to press the button on the dash every time I stop the car to stop the beeping!

    Is it difficult to replace the sensor?
