If one parking sensor go's down will it stop the overs from detecting obstructions

Please help????????????

If one of mine temporarily fails (goes down) due to water ingress (a well known problem) the others still work. Not quite the same I know but might give you a clue.

I'm sure it does as it needs all of them to function

This How To may help - was for MK2 but probably the same setup

All sorted

One sensor down on the o/s so quite a easy fix
