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