Parking Sensors A180

[arashtrip]

Hi I have an A180 2011 and its rear parking sensors keep beeping (which is very annoying) randomly. Sometimes they are fine but sometimes they keep beeping.

I tried to apply WD40 and it fixed the problem for a short time.

Is it something that I can do it DIY or I need to fix it in a garage?

Thanks

I had a B180 doing the same thing, solved mine by giving the car a good clean especially the bumpers. I really do not know what was causing it, but every time they started playing up again, my wife told me time to clean the car again
