Dear All,

I hope you are well! I NEED SOME HELP PLEASE!

My Touareg 2015 3.0 TDI 262 HP with 45.000 KM shows the following errors after a Carista scan.
-P2111 throttle actuator stuck open
-09124 which has no description in Carista but seems to be related to the P2111
This started after driving and a "start and stop error" message on the dashboard
I also have a 06656 can network gateway that seems to be related to the battery. I installed a new battery just in case and run the initiation process with completed successfully according to Carista! But this error was not present before changing the original 8 years old battery with a OEM Varta.
The car drives perfectly but the start and stop system does not work and I have the engine management light on.

The throttle actuator, part 059 145 950 AF works fine. I cleaned. When accelerating it opens and closes.....may be there it is an electrical problem with the position sensor? I bought a replacement part and I will try just in case, it is quick to swap.

I am thinking the problem is with the second throttle body, part 059 129 593 AS. I have never seen the flap moving and cannot move by hand. it is the dirty part in the picture below that I have now cleaned to perfection. I suppose I can take it off and open the cover to see if the fact that does not move is due to some broken parts inside? Am I suppose to be able to move this flap by hand? It does not but it might be due to the type of mechanism.
BTW what is the function of this flap? Clearly it stops air flowing through part of the intake but why?

Thank you!!!

part 059 129 593 AS, before cleaning. number 7 in the diagram

throttle actuator, part 059 145 950 AF, number 25 in the diagram

The swirl flap is used to tune the intake manifold flow in order to optimize performance\efficiency under a wide range of operational rpm\load ranges.

Can your tool do output tests? With our proper VCDS tool, we can run output tests on many things like flaps, actuators, etc.

but I suppose then the engine will not work well? drove 50 miles no problem. engine light not on. goes on when activating start and stop

don't think so. the error comes with a list of data, will post here.

So you asked what it was for, and what it did. I told you.
What metrics did you measure in those 50 miles to indicate that you haven't lost any operating performance or efficiency?

I did not check live data but the engine has been operating without any flaw or the engine light going on both in traffic and highway at high speed. No smell from the exhaust, no change in consumption . The engine light goes on immediately when I turn on the start and stop system with the button. Mine is permanently off and I only turn it on in the right driving conditions.

I struggle to understand how a throttle body that seems working perfectly is related to the start and stop system. Of course there could be some links but then I should also see an error when driving or have some engine malfunctions? Should I trust Carisa indicating error P2111 "Throttle body stuck open" when it moves perfectly? perhaps is a different part?
what is error 09124? I cannot find any description

I have booked a VCDS check locally but is only in a week and I have an appointment with my local dear but in 3 weeks!

THANK YOU!

I'm not sure what you're asking, if anything.
A diesel is not controlled by it's "air" intake, so the term throttle body is not the same as in a gasser.... it is not used for the same purposes.
If you're still talking about the previously mentioned swirl flap and think its unnecessary, go ahead and remove it. I briefly told you what it's for. Go ahead and read technical SSPs on your engine if you'd like more details.
The same documents will also explain the purpose of the throttle actuator. I won't waste my keystrokes trying to explain it to you since you'll just tell me that some crappy scanner is giving you some code that doesn't mean anything to anyone..... did you contact the manufacturer for support? Does this Carisa junk come with documentation, manuals, etc?

I apologise if I have not been communicating properly and I have cause you frustration. sorry!

The mystery continues. I checked the error with a different scanner: car scanner. Got the same errors than Carista P2111, 9124 ,00656. deleted them an now everything is working......no problem activating start and stop!!!

I still have error 06656 but this does not cause any dashboard light and started when I changed the battery. See below details. I feel this is related to the new battery but not sure what I need to do. I did the registration process of the new battery a few times and it always complete successfully.

You're not causing me frustration, but you're not providing proper details.
What is the actual code being reported, including whatever description, freeze frame data, etc.
You're all over the place.

Thanks, I have provided the freeze frame of the last error left!

So these scanner don't give you any descriptions for whatever code you have? (once again, you provided two different codes)

Francesco Mosca

Discussion Starter · #13 · 13 d ago

no they do not give any description apart from manufacturer specific.....

P2111 says throttle body stuck open. but which one is it? number 25 or 7. number 25 is working perfectly although there could be problem with the position sensor

So as per my earlier mention, your generic tool is junk.
It's giving you useless info\codes instead of specifics.
Also, as previously mentioned, with a proper tool, you can perform output tests, read live data, etc.
Can't this garbage read data off the throttle actuator and the intake flap? Position, voltage, something?

Here's what a proper tool would report on the very similar engine code we have on this side of the pond.

Address 01: Engine (J623-CNRB) Labels:. 059-907-401-V2.clb
Part No SW: 7P1 907 401 C HW: 7P0 907 401 K
Component: 3.0TDI FSA H21 0010
Revision: 56H21---
Coding: 292A4012237600050000
Shop #: WSC 95884 999 00000
ASAM Dataset: EV_ECM30TDI0117P1907401C 001011
ROD: EV_ECM30TDI0117P1907401C.rod
VCID: 303916C2BAAD461B3F3-8065

2 Faults Found:
9123 - Throttle Actuator Control System
P2112 00 [032] - Stuck Closed
Intermittent - Not Confirmed - Tested Since Memory Clear

9124 - Throttle Actuator Control System
P2111 00 [032] - Stuck Open
Intermittent - Not Confirmed - Tested Since Memory Clear

Readiness: 0 0 0 0 0

So, if you had this kind of tool, I would say that's your Item 25 if I had to guess.
Since your FF data also shows that .....

I would erase the code to see if it comes back.... since it's only happed once, it could've just been temporarily jammed up, stuck, whatever. If it starts happening all the time, then you have some sort of issue... maybe a connector, maybe an impending failure, etc. You need to look at whatever values\data you can read in order to determine the next steps.... or you can load up the parts canon and eventually, you'll guess the right part.

Amazeballs.... look at all the crap you're not disclosing! Now I'm frustrated. FFS.

So, what's your question now?

Thanks. What scan toll do you recommend?

BTW I have bought a new Throttle body but not sure this is the part causing the problem.

My question is: is the throttle body part 7 or 25 in the above diagram?
