I have FR Leon with rear parking sensors. Just recently they started having a problem. When engaging reverse gear, system does not give out the normal beep. It waits a bit and gives out a lowish tone and sensors dont work when near object. So I figured one of them is out.

Has anyone changed a sensor? Do I have to remove the rear bumper to do it and how is it done? Thanks!
