Pull off the front engine cover and follow the vacuum line to the driver's side.

A couple of more pictures are added because some people have no idea where this vacuum hose is connected due to completely missing section of vacuum hose.
Routing of the vacuum hose is marked with a red line.
The section with dotted line is well hidden and hard to fiqure out where it ends. It is connected to a hose with a metal clamp below the power steering fluid reservoir (circled in the picture).

Close up view of the connectiong hose here. I replaced the broken section with a silicone vacuum hose. It was not easy because there is not much room. You will have more room if you free up the power steering fluid reservoir and push it aside.

You need 3.5mm ID silicone vacuum hose like one below. Cut off the existing hard line and make it as an male adaptor.
If I am redoing it, I will buy a vacuum line adaptor for the side under the power steering fluid reservoir to make it stronger.
You shoud be able to get all of them at Autozone.

Just wondering if you had any experience with testing the Intake Manifold Runner Position Sensor?
Thanks,

Yes, just pick up some 3.5 mm silicone vacuum hose from Autozone or the like and some male adapters. A word of wisdom is to pull the reservoir tank (directly above) off, to get your hands easier access to the hose that is broken behind the headlight. Also there is a small cable hold that you can undo the vacuum line to give yourself some more slack. All in all about a half hour job if this is your first time.
Thanks everyone else for their posts, really appreciated!

Of course this is an old thread, but would anyone kindly point me in the direction of where I can find photos of those hoses on the 4.2L V8? I'm getting the P2006 and P2007 codes on my S5 with the 4.2…
Thank you in advance.
Thank you in advance.

How have you tested that the hose is in fact intact? Once you've done a smoke test on it, you should be able to confirm this.
