AUDI Q7 2008 3.0TDI Engine CAS - Throttle Error 001592 P0638: VCDS Screenshot & Photo Included

Question

AUDI Q7 2008 3.0 TDI ENGINE: CAS
During normal driving, the engine light came on today.
I didn't notice any drop in power.
After connecting to the computer, vcds showed the following error: 001592 P0638.
If you try to delete it - it returns immediately - no matter if the engine is turned off or not.

I attach a screenshot from VCDS and a photo of the throttle

Do you have a cable with alledrogo and you do not know which part has broken? Turn on the ignition, remove the plugs and you'll find out what's what.

ste · Accepted Answer

J338 (Throttle body actuator) it is in your picture No.3.
It should have a 4-pin plug; cable colors: brown, red-gray, white, blue.
The method given by the domex colleague is reliable, if you unplug the plug from the j338 module, you should get an error about j338 with the description "open circuit"

maybe it broke?

dziugi · Answer

In what channels can it be tested?

Pawel wawa · Answer

Damper to replace / regenerate. Still see the beam to see if it is starting to break. Start watching from the plug, take a 20 cm look at it, carefully pulling on the wires.

Hello, thank you for all the hints. It looks like the throttle just gave up. the part number read is: 059129086K, can I buy a stimulant with the same number but with a different suffix - M?

dziugi · Answer

Saying there is a damaged throttle, what do you mean (in relation to the photo posted)?
no.1 or no.2 - throttle flap adjusters (whatever it is called)
or No. 3 - dampers
Or maybe some other element that I missed?

The error in VCDS reads: 001592- throttle body actuator bank 1

dziugi · Answer

I have the original VCDS - as you can see from the version - in the attached photo. After disconnecting the next plugs, I had other errors - hence the question for experts on the subject.
In which measuring blocks I can check these specific components - specifically the throttle flap actuators - because I suspect them - and specifically the left one, in photo no: 1.
I will only mention that during the observations during the starting of the engine - both of them present themselves ...
Is this a good lead or something else?

Buddy SSP puller for this engine and maybe you will master the topic.

dziugi · Answer

Hello.
A new damper has been ordered - delivery will take about a week.
Thank you for your help.
I also read on other forums that I will have to do a short adaptation using vcds. I've read a lot of topics but they refer either to a different transmission- kwp2000 ... etc, or to different engines.
Does anyone know and share their knowledge about the correct procedure for this engine in this car?

dziugi · Answer

Hello. A short update - the throttle has been replaced with a new one - as indicated by the user: STE, and everything returned to normal. Thanks to everyone for your help.
