These were the codes using Ross-Tech on a 2006 Audi A6-3.2 with 60k miles.

P2006 - Intake manifold tuning valve-bank1- stuck closed
P2007 - Intake manifold Flap - bank 2- stuck closed
P2404 - Evap leak pump sense circuit
Car run OK except the engine light (icon) shows up on the dash.

I erased all the DTC but they came back again
Any help or advice would be appreciated.
Thanks

In looking at the Bentley Manual, you probably have a leak in the intake manifold.

ok guys finally i had time to wort on my car.
here it is what i got:
Saturday,12,September,2009,10:14:43:12180
VCDS Version: Release 908.0
4 Faults Found:

008304 - Intake Manifold Tuning Valve (Bank 1): Stuck Open
P2070 - 006 - Short to Plus
008198 - Intake Manifold Flap; Bank 1: Stuck Closed
P2006 - 006 - Short to Plus - MIL ON
008199 - Intake Manifold Flap; Bank 2: Stuck Closed
P2007 - 006 - Short to Plus - MIL ON
008212 - Intake Manifold Flap Position Sensor (Bank 1): Electrical Malfunction
P2014 - 007 - Short to Ground - Intermitted
from reapir manual orientation i did:

Disconnect the electrical harness connector from the Intake Manifold Runner Position Sensor G336 - 1 - .
1 to Ground (GND) Battery positive (+)
2 to Ground (GND) about 5 V
3 to Battery positive (+) Battery positive (+)
I did that(ignition off and start on) but on point 1 to ground :i had 7 volts and from 2 to ground i had 0 volts,so looks like the 12 and 5 volts are missing (i think this tunning valve it is a potentiometer....(i did check fuse 3 (5a) for emc and it is good).
My problem now is that EMC(J623), it is a seal unit and i dont know how check the harnees(next step by manual) to see if i got a open wire between EMCmodule and connector G336.

Please let me know if i'm going in the right direction ...
Any help could be fantastic.
Thanks

i will answer myself...

There is a TSB (Number 24 08 76 20019485/1) for three out of four of those fault codes which indicates that "Vacuum line cracks" and/or "Leaking IMT actuator" are the most likely culprits.
I will check those and let you know guys

Well guys finally i got my car fix,i found a broken vacuum line(plastic hose)engine front bottom side.So no more codes...
Thanks to everybody who was trying to help...

Is there a picture or a more specific location / connection points for this hose?

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.
