S6 - intake manifold flaps stuck

[ferooo]

hellou,
I've got fault codes for my Audi S6 facelift - intake manifold flap stuck for bank 1 and 2. Is it problem with swirl flaps or solenoid that controls flaps or vacuum actuator or pressure leak?
Also on dashboard is fault that I cannot exceed 4000 rpm. First time it happend about 10days ago, I changed battery (was almost dead) after that it was ok for 2 days, but then again "max 4000rpm". Now 1 from 5 times I drive the car there is no fault (sometimes I can drive without any issues, but a lot of times fault code).

N316 actuator is failing. Not an easy fix. Might can do it if you find a way to lower the engine 2-3 inches with out completely removing it. I have done it. Basically loosen up the fram, have an engine hoist holding the engine from lift points, loosen up the frame completely and carefully lower the hoist. Remember you have hoses and wires connected so you can’t go to far.
The book says remove engine

so you had the same problem or you had to only lower the engine for other issue? :)

I rebuilt An rs7 for last month and had that issue. I also have an rs7 (personal car) that I dropped the engine. So I am familiar with the many different ways of taking it out or lowering it

I took car to the audi dealer to solve it and he did
It was problem only with solenoid valve (broken insert), they replace it with new part (06H906283B) and also, just for sure, replaced vacuum hoses (079131055DE).

Interseting. How much did this cost if I may ask and how many hours of labor?

2013 audi C7 S7 RS7 S6 RS6 4.0 P2006 P2007 intake manifold runner codes.

This can be useful, admin can move it the correct forum if wanted.
Long story short.

Bought 2013 S7 that was involved in light front end accident. Throwing intake manifold runner codes on both banks P2006 P2207 seemed suspicious as it would be unusual for both manifolds to go bad at 80000k.
Checked all the solenoids and vacuum lines - all good. When manually applied vacuum - runners seem to open and close as it should ( checked 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 movement of the flaps.

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))
