Hello there :)

I'm looking for information about this sensor but I can not find anything. Anyone know what it is and what it does?

Thanks for the replies:)

This is the pressure sensor to control the waterspray on the intercooler.
I believe that from 0.6 bar and up the circuit is closed and thus the pumps are on.

You are saying that with the pressure of 0.6 circuit is closed so when the water cycle turns because I admit that I did not understand the last sentence.

Thanks a lot buddy. I knew that here I will find the answer.

When the sensor sees 0.6bar at the plenum, the switch part of it closes and activates a relay which powers up the 2 pumps attached to the water bag in the boot.
There is an indepth article about the waterspray system on the website.

Don't worry about the language or using Google Translate, I'm sure we will be able to understand you fine.
And if you do have a problem, just post it up in Polish, I'm sure there are others on the forum who can translate it for you.
