All turned back to VW. Now a 2017 Hundai Tuscon. Not a single squalk in 10k miles.
And life is good! So... What was wrong with the old valve?

if anyone else has encountered this problem I would like some advice.
A few weeks ago I noticed that the car was shaking at a stop, Golf 5 1.9 2006, no error appears on the VCDS, I removed the hose from the intake valve and observed that it does not act when I stop the engine, I cleaned it but for nothing, then I changed it and for nothing, it still does not close when I stop the engine, I checked the wires on the jack, they seem fine. I even checked the fuses in the panel next to the battery, all ok .. I gave it output test from vcds but it still does not work. So what could be the problem? In vcds why I don't have an error if the flap doesn't work anymore?
