Not connected hose on an AGU 20VT
Hello guys and congratulations for this reall helpful forum!
I have a '98 A3 18T / AGU engine and it's remapped by ABT (193ps).
Recently i noticed something weird on the intake manifold.
There is a small hose that is not connected on something and it's tapped by a screw :/
I have no idea what is this,but looks not so normal :)Can somebody tell me what this can be and where should be connected?
I post two photos,so you will see exactly what i mean.
Another question is if a N75 J valve could help me for little more boost.Is it ok to switch from my ordinary one?
Thanks in advance,keep the good work!
