Trying to locate the vacuum line behind or under the manifold for P2006/p2007 code

I had the check engine pop on about a month back for P2006/p2007. Either stuck closed or open the manifold flap. Others seem to have had this problem before. Wasn't sure if the solenoid was stuck or what. Long story short after about 2-3 days went off on its own for about 4 weeks, cool. Just the other day it popped back on for a day or two and goes off. Weather has been kinda crappy in PA, so haven't been able to dig around the engine bay, as i am in a condo complex.

When i have the motor running i can hear a "hisss" sound coming from the top of the bay, right behind the top of the plastic V8 cover. I popped that off put couldn't find anything. I assume i might have to move some things out of the way? I need a diagram for the 2010 manifold for my S5 as i believe i have the updated one. I searched and i think the one i found is for the 2008 manifold before they changed it. Or if someone can generously guide me the easiest way to get to it.


I am pretty certain its just a vacuum leak. Car runs and drives beautiful, no rough start or idle nothing. But i can hear a hiss which sounds like a loose or disconnected vacuum line, but would be helpful if i had a diagram or someone could explain where exactly its at or what i need to remove to get to it. Engine light will eventually go off on its on after a day or so if and when it pops on.

Thanks I think I read that one. I've read a lot of threads people had a disconnected vacuum line as well. I think that's my problem. I can literally hear the air hiss by the back of the manifold. I just need a diagram to trace them out and see the easiest way to get to them on the 2010 manifold.
