P2006 Intake Manifold Runner Control Stuck Closed
Check engine light came on shortly after purchasing my
2007 Audi Avant 3.2 with 60k miles. I borrowed my daughter's OBD
reader and read P2006 and P2007 "Intake manifold runner control
stuck closed" for Bank 1 and Bank 2.
This is not an uncommon problem as I could see from many online searches.
I saw reference to a Technical Service Bulletin (TSB) 2019485
which was referenced in many places but whose content I could
not find online. Actually most of the references were to the /1
version of the doc, but it was updated in July 2010 to 2019485/2.
I was about to get the online Bentley manual when I saw a rather negative
review on the forums and some responses that recommended alldatadiy.com
as an alternative. That is sold as either a 1 year or 5 year subscription
but limited to a specific car. Additional cars can be added quite cheaply
though.
Before purchasing I did a search for "alldatadiy promo codes" and
quickly found one that knocked $5 or so off the five year rate
(bringing it down from $29.95 to something like $24.95.
For some reason I was not successful is searching the site for
the TSB number, but there is a TSB link which takes one to a long list
of TSBs for my car (since I had subscribed). I searched the titles
for P2006 and found the right one, and when I opened it, I found
the TSB number above in the file.
Having seen this referenced a number of places I was looking forward
to it's insights and revelations, but actual text was very
concise. It says
One of the following DTCs is stored:
^ DTC P2070 (Intake Manifold Tuning (IMT) Valve Stuck Open).
^ DTC P2006 (Intake Manifold Runner Control Stuck Closed, Bank 1).
^ DTC P2007 (Intake Manifold Runner Control Stuck Closed, Bank 2).
^ May be slight power reduction at high RPMs.
This condition does not cause stalling.
Technical Background
Vacuum line cracks.
Production Solution
Updated vacuum line.
It also said
^ DTC P2006 and P2007 may be caused by a leak in the Manifold
Runner Actuator diaphragm.
And
The vacuum line (06E 133 633) attached to the vacuum pump in Figure 1
is usually the causal part.
However the figure was useless for determining what they were talking about.
I happened to be at the Audi dealer to update engine management software
(a recall) and I already had an appt for my favorite mechanic to look at
check engine light condition next week but... what the heck, I'll just
buy the "causal part" and even if it hasn't failed yet, it probably
would. So I went to the parts department and gave him the part number
06E 133 633
He said these failed all the time so they kept them in stock. I asked him
about the alternative 'Actuator Diaphragm' but he was not aware of
that, nor did it appear that part showed up with that name on that
part of the parts diagram. So I didn't pursue that further.
He did say that people mistakenly often bought this potentiemeter
that reads the position of something inside the valve cover, but that
the usual successful fix was to remove the cover and clean out
all the gunk in the intake manifold. But unclear if any of that
applied to the faults I was reading.
Anyway part was $35.00
Back home, I thought I would just check out this part. I popped off
the front-of-engine cover and started wiggling vacuum lines at the
front of the engine. Just as many forum postings mentioned,
simply by wiggling it I saw bits falling off. But
where did the 'other' end plug in? That's where this very helpful posting
with pictures came in.

There is a 5 inch or so rubber tube that it plugs into and where
to find it is clearly indicated in the picture in that posting.
The only hard part of this whole project was removing what was
left of the vacuum line from this tube.
Noting how the old line was routed (down near dip stick) and
looking again that the photos in the forums link above, I
replaced the line.
Now I wait and see if the fault light stays off.

My 2008 Audi A6 Quattro v6 3.2 liter shows P2006 code and...
My Audi is showing codes P2006, P0014 & P0366, and I was trying to figure out what exactly I have to do to fix it? I have looked up these codes online which I have gotten a couple different solutions for each one. So Im just trying to figure out where to begin? If anyone could help me that would be really appreciated!! Thanks!!
