Unhappy Intake Flap Motor aka Anti-shutter Valve aka PITA

Ok, so I'll start at the begining.

Bought this car at 52k. After a few days of driving around I got an engine light. I had just gotten my vag-com cable so I took a look. P2112 Intake Flap Motor malfunction blah blah blah. Ok, no big deal, not critical but it throws a light. Long story short when I took it to get inspected for registration and tags they told me the gears of the motor are stripped. Wanted 600+ to fix it (Not covered by powertrain because it isn't directly part of the motor..... ok.... sure...) Found one online for 249 and installed it following bently. Went to start it up and it started, low idle, die. No lights, no codes. Pulled everything apart again and turned on the car but did not start, the valve closed right when I turned on the power.... That can't be right... or is it? Anyone replaced or serviced this sucker? Manual is no help, and I haven't found anyone that knows exactly how it functions on the 06 Sedan MKV PD.

BTW I have it unplugged right now and it runs just fine, just still has a light and shut off a little ruff. (As expected) Just wish I could have the car be happy with no codes or lights.

It should only close when the car is turned off I believe. It is used to make sure the engine doesn't keep running when shut down. It cuts off the air to the engine so it can't continue to run anymore. It should also help in the case of a runaway engine. Where did you buy the replacement part?

Impex

I'm starting to think more and more that it is something electrical. The bently manual is no help on what the voltages etc... should be for the motor or the harness.

This flap is also used to restrict the intake to increase EGR; if memory serves, there's an adaptation needed for it. Try a search on both this A5 and the earlier A4 sections...

I had mine replaced at a couple thousand kms. Same symptoms you describe. Dealer replaced the whole intake flap assembly under warranty.

Well there is only one way the connector can go in. The wireing diagram doesn't help much if it is wrong.

@2footbraker I'm at 54K miles and they told me it is out of warrenty. I have replaced the entire unit but that didn't help.

Anyone want to volunteer to meter the wires for me and look at the behavior of the motor when the ingition is on and when it is off. =)

All I show is one connector and seals - maybe its leaking they say do not re use the seals. You may need to test voltage at connector.
You turn ignition on and it closes - the connector cant be plugged in backwards ? can it.

When you turn ignition off it should close for 3 seconds and then open.

New seal came with the new part.

The connector only goes on one way, as I stated before.

Ok, I'm going to bump this in hopes that there is a MKV expert is out there. Please, I'm begging.

We have dealt with a similar occurrence.

I'm not 100% on this, but electrically the EGR valve works in conjunction with the flapper.

We replaced the EGR and that fixed it.

Like I said not 100%, and I would hate for you to purchase an EGR valve and not solve it.

Ok, I sware I'm going crazy. BlueCTTDI (thanks bud) convinced me to do a function test through the vag-com this evening. It seemed to be working just fine, so I cleared all the codes and it started right up, no CEL, no codes!! I guess something in the computer must have been f'in it up when I first installed it. Thank you all for the input I'm just happy to have no CEL and a fully functioning car.

No I just need to replace that right tail light bulb.
