Hi Bruno, Welcome to the forum.

I am not really sure about the switch, I think it is supposed to be 0.7 and above that it switches.

But I have over ridden mine so I just have a button next to the drivers seat.

p.s - Post some pics of your car :D

Hi Bruno,

don't worry about your English. All the waterspray pressure pumps should activate at 0.7bar. Can you get a look at the switch and see if it has a part number on it. Have you had a look at the main website, there is an article on there about the workings of the waterspray along with all the part numbers.

Hi Bruno,

The pressure switch is Alfa part #60809006 so not sure if the one you have is correct. If the switch is not sealed correctly it might be leaking pressure and so it might take 1.1bar to trigger it instead of the standard 0.7bar.

Sometime this was talked (maybe in previous forum), but the ideal thing is to install a thermal switch, so air reachs a certain temperature, the water spray is activated.
It´s a simply mod as only need a thermistor and easy electronic.

water pomp circuit it realy simple to make this ,and it's not too expensive!!!
