Hello everyone,

I am new to the forum and I have a 2011 vw gti. I was getting a p2015 code so I had tried to run the basic setting since I already replaced the manifold. Now the code p2004 pops up constantly. I can clear the code but as soon as I start the car it comes right back. I replaced the whole intake manifold for a second time with a new one and still the codes appear. I replaced the vacuum line that supplies the vacuum to the solenoid and still no luck. Does anyone know what can fix this.

Thanks in advance

I also forgot to mention how I try to run the basic settings again and it begins the adaptation. I see the specified value move up to 98% then drop back down to zero and then the adaptation fails.

make sure the pins of the connector plug are not pushed back...make sure they are all nice and neat and visible with the naked eye

Pins look good. Does anyone know if I take off the vacuum line that goes into the solenoid that controls the flaps if I should feel something?

Okay, interested. I don't own a car with runners.agree with JMR but I guess what dictates the command of this valve and does VAG have the ability to bilateral command? Code states stuck open, how is that verified, or once commanded there is no change is that validation?.

You stated manifold was off, was that for this issue? Once on the road and pushed does vag have the ability to show flap was commanded, and if commanded and no movement, then issue is mechanical or information did not transfer through the plug, as I see it.

If we know how it is commanded, maybe mighty vac it, then electrically excite it. Again speaking out if turn here as maybe is PWM.

Again can't see the wiring but learning just like you, have I mentioned how much I like this site!!

Are they looking a bit loose ? Opened too much ? I ve had numerous issues with this imperfect contact problem

When I look at the live data when driving the specified value goes up but the actual value doesn't move. Similar lot when I try and run the basic settings. The specified value so what the ECU is commanding goes up but the specified stays at zero.

Yes I replaced the whole manifold with a brand new one to try and see if maybe the sensors on the manifold went bad or that something happened with the flaps themselves.

Ya the pins looked fine not to open and not loose at all and the wires themselves don't have any cuts.

Okay, so data from Vag states info sent but no change on the other end. The fact that it does not denote open, or shorted, ECT, means the ECU sent the data but nothing happened.

I'm just speaking out loud here, would appear it is mechanical at the flap or sensor/servo, (not sure here) is at fault. Without have the expertise of UWE here and how the data is interpreted IMO, I would back prob flap sensor, then see if data actually reached the sensor whiel driving in real time.

All this might be foolish as again it did not state open/shorted/voltage high or low. I am not a big fan of replacing parts until I condemn then. Also not a big fan of back probing for data as occasionally the pressure from the back probe on specific sensor will actually make a connection that is not there with probe removed. As they say once you have been bitten wakes you up. I like to pierce using proper tool if space is available, (sometimes not) then of course fill the probe hole for future corrosion.

Got a link to the intake manifold you bought?
New aftermarket? Used? V.W.?

I have changed these many times but always used original V.W. They come with with new runner components. Position sensor, solenoid and vac. diaphragm.
All you need is Vac. at solenoid with engine running. Output test should work the solenoid and click it. Key on engine off for output tests. Handheld Vac. pump to work diaphragm.

Good Luck

Its was a new aftermarket manifold from URO parts

Diaphragm is good I already tested it.

I must emphasize that the code P2004 only posed up after I ran the basic settings on the runner flaps and failed. Now every time I try and run the basic settings it says adapt run then ERROR.

This is sometimes also the problem with aftermarket parts, because if it don't work you sometimes still don't know why.
For example: i bought some cheap abs-wss, they seem to work, but the signal was so weak that i still bought the genuine part.

UPDATE. Had a Volkswagen specialist look at it and they said I should replace it with an OEM intake manifold. Guess I'll have to do this job a third time.
