Hello dear vwvortex members,
Recently i bought an Audi A4 B9 with 3.0 tdi V6 engine, 272CP(CRTC). Yesterday i was doing an air filter replacement and i have seen some kind of butterfly valve on the downside of the airbox. What was curious, was that the electrical connector that actuates the butterfly valve was connected to the electrical system of the car, but the vacuum line not. So, my question is, why is the vacuum line disconected and, is it normal ? Or i am missing some vacuum lines fromt the car?
thank you.
