hi all,
my fl2 sensors are working fine on the front but in reverse there is just one long continous sound, I have checked them and they all work fine all emit a clicking noise) could it be the reverse switch on the enginge?

Try cleaning them with an old toothbrush as they tend to get a film of dirt over them. Be careful not to be too hard so you push them through though!

I doubt its the reverse switch as if that was faulty nothing would sound?
