3.0 Vacuum line problem
CEL came on. Looked at vacuum hoses and noticed one that wasn't connected to anything. It's the one hi-lighted with yellow. It's located in back of the 3.0 and descends down behind the engine. Any ideas where this one belongs?

There's a vacuum hose diagram on the top of the ECU cover, although part of mine has peeled away. It looks like the hose goes to a vacuum valve attached to the rear of the passenger side head. I had a look at my A4, but couldn't get a real good look because of all the other stuff blocking the view & I didn't want to start 'digging'. HTH

The line wasn't connected to anything. I had changed the engine oil a month prior and found a plastic plug on the belly pan. Couldn't find where it belonged, so I put it in my toolbox. Well, finally figured out that it plugged the end of the vacuum line. Now the car runs perfectly fine after I changed all the hoses. Does anyone have a pic of the vacuum hose diagram. Mine is completely gone.
