P2006/2007 code help video inside I believe it's a vacuum leak

[Vanimal]

2010 4.2L S5

Driving home today i noticed the check engine light come on, great! First time since I've owned everything seems fine as usual. So I drive to autozone to use their handy dandy worthless scanner and I pull the p2006/2007 intake manifold runner stuck closed bank 1 and bank 2. Car doesn't start rough or idle rough or anything.

I starting googling & lucky to some it turns out to be a vacuum leak. I popped the hood & I do hear some hissing like air escaping behind the plastic manifold. I googled around but nothing, seems to be a little lower than I can reach at the moment.

For those who solved this problem is the 2006/07 referring to a particular cylinder? Anyone who's on PC have a vacuum line diagram handy as I'm on the road via mobile.

Figures I have to go to Philly tomorrow, so I'm probably not going to take it apart tomorrow. I presume I'll be OK as its driving totally fine. I've dealt with vacuum leaks in the past with my b5 S4 which was 10 times worse. Hopefully this is a matter of just a old withered rubber line that needs to be patched or replaced. Car drives the same when I picked it up in August .

Here's a short 7 second vid, not sure if you can hear the hissing. I'm hoping it's a vacuum leak . As stated she runs great, must have been that Italian tuneup I was doing this week & popped a vacuum line haha!

I had the same problem. Sit down, for this, if you have what I had….
First, you should check for (and hope for) leaks. There is a vacuum line running on the passenger side of the engine along the valve covers. There is another line that runs to a blue ball on the driver side, low in the engine bay, remove the under tray. These run to a solenoid located in the front, driver side of the engine, pretty much in plain view. I did all this, and all checked out. This is where it gets weird….
There were two different intake manifolds, an ally one and a plastic one. Most of the diagrams online will show the ally one, which also has a different flap mechanism. I had the plastic, and I assume you do as well. My issue was a vacuum solenoid leak, and this particular vacuum solenoid is located under the intake manifold! It is located near the front, driver side corner, under the intake manifold. This is a second solenoid, which helps operate the flaps.
I did end up taking it to a local independent Audi mechanic here, and I was only charged about $200. They expected to have to remove the intake manifold, however, they were able to lift it off enough to access the solenoid, and replaced it with one they had laying around. They did not charge me for the solenoid! If they do have to remove the intake manifold, you might want to have a carbon clean at the same time.
If you still need a diagram, and had one at one time and I can dig around for the link.

Thanks!

My problem "seems" to be exactly what you experienced. I do in fact have the plastic one. I moved a bunch of lines around and nothing amplified the hiss. Which leads me to the it's probably under the manifold like yours. I'm hoping I can easily resolve the situation like you did. How long did you drive on it until you fixed. You think it's OK until I get to it probably next week or when I get back from Florida March 22nd? It's pretty cold here now with no garage. I'd assume I will be fine as the car is not driving like RS gimped in any fashion. No odd start up, no rough idle etc. so I assume is be ok postponing it 2-3 weeks. I put 100 miles or less on the car per week.

I drove quite awhile, as I think the flaps still work even with the leak. I hooked up a VAG, and was able to monitor their movement. I also did not have any noticeable rough idle or any other codes, so I think you will be fine to wait. I took about a month and 1/2 trying to diagnose, w/o any long term issues. If you need additional help, let me know.

Here is a diagram, and the one of the #13 solenoid, is the one located under the manifold.

Good news, for the moment... Came out the next morning on Saturday & check engine light was off on its own. Now Sunday night it's still off. Maybe the solenoid was stuck or? I'll report back if it comes back on. But I appreciate the help.
