Guys, Just a quick Question. Can you disconnect 2 out of the 4 Parking Sensors and would it still work? At the moment when i engage reverse I get a constant tone, but this is because the 2 inner sensors are picking up the towbar. So if I were to disconnect these inner 2, would it still work...

my parking sensors do not work, when i engage reverse the sounder just goes to a constant loud noice. i have put it in reverse and felt and listned to the sensors in bumper to find the ones that are not working but they all make a noice and vibrate. So now im completely stuck on how and what to...
