008197 - Intake Manifold Flap; Bank 2: Stuck Open
P2005 - 002 - Lower Limit Exceeded - Intermittent

Update:

Well nothing was replaced. All was checked and in good order and functioning properly. They said they recalibrated the flap motor (what ever that means) The hesitation is gone and the shifts are smooth again :-) We will see if it pops back up.

Update #2:

No EPC light and the car is way smoother than ever when I get on the throttle. What ever they re-calibrated seems to be working. At least for now.

calling for service tomorrow :-(

Did some STFA'ing as well and I'm thinking that this might be a great time to port/polish the intake manifold, as done by another member here. I have yet to VAG it though.

Time to fix my porting tool.

I had the EPC light come on last week as well..... I VAG'ed and cleared the same codes that popped back up yesterday.

I like to make sure it just wasn't a fluke before making a service appointment since the dealer is 2 hr away.

work only to have them replace the intake manifold....also wouldn't be too good for your wallet if they went to replace it and noticed the work you did to it and blamed you for the failure.

Just a thought from someone who has had the EPC light stay on and the intake manifold was replaced due to stuck flaps as a result.

and after replacing a sensor and then one of the vacuum accuators in the intake manifold, the problem still happened. My intake manifold was then replaced as well as one of the two vacuum pumps. Anyway, my problem seems to be fixed now as the EPC light hasn't been back on in about a month.

I believe I had the same or similar codes you mentioned, but I ended up taking the car to the dealer 2-3 times to get the problem resolved. This was mostly due to the intermittent nature of the problem and the standard troubleshooting procedure that Audi wanted followed (which is fair enough).

Have since switched over to a Honda CR250 which is slower but has a bigger class to race in.

Based on some of the searching it seems that it may just be a vacuum line, if that were the case it would be easy enough to fix at home. At any rate, I'll probably wait to see if it comes on again and then take it to the dealer for further diagnosis.

It could be something else but at least they will have the motor on the shelf.

The RS4 manifold flaps are actuated by a 2 vacuum diaphrams - one for each bank. The flaps in the 4.2FSI Q7 are actuated electrically (via solenoid I'm assuming). I don't see how the term motor applies to either.

marke K-40 that was installed. so they re-wire the whole thing and the lite came on again.

Condition
MIL on with DTC P2015 and/or P2020 in the ECM memory.

Technical Background
Possible cause is a vacuum leak at the vacuum supply hose fitting for the Intake Manifold Runner Control (IMRC) valve N316. The vacuum supply hose fitting is located underneath the center of the intake manifold.

We'll see.

I did receive a nice RS4 hat..... the service writer is really striving for extremely satisfied. :-)

Best bang to buck out there, period. The fastest guys run times at Laguna Seca in the 1:23 range.
