2013 audi C7 S7 RS7 S6 RS6 4.0 P2006 P2007 intake manifold runner codes.
Long story short.
Bought 2013 S7 that was involved in light front end accident. Throwing intake manifold runner codes on both banks P2006 P2007 seemed suspicious as it would be unusual for both manifolds to go bad at the same time at 80000k.
Checked all the solenoids and vacuum lines - all good. When manually applied vacuum - runners seem to open and close as it should ( observed each window with the good light and a mirror). Everything seemed to work as it should but codes were still there.
Ended up lowering the engine and removed both intake manifolds.
And found out that both manifolds had broken plastic pieces stuck ON THE INSIDE under the flaps ( and could not be seen with the mirror) which restricted the 100% movement of the flaps, and apparently getting stuck from time to time.
Those pieces appear to be a part of the front intake that was damaged in the accident and apparently the pieces were sucked in.
So if you have a car that was involved in the front end collision popping these codes - good chance you have the same issue I had.
Get a good quality pin camera and check for broken plastic pieces stuck under the flaps before you remove the manifolds.
Hope this helps some one))
