AHK Control Unit Coding for Audi Q5 8R

Hello everyone.

I installed and coded a trailer hitch on a 2013 Q5.

The following problem has now arisen:
All the functions are present; the trailer is detected (Side Assist deactivates, and the symbol in the MMI changes, and rear parking sensors are disabled). The light is working, and the defective lamp detection is also functioning.
The problem is that as soon as the adaptive cruise control needs to brake, it deactivates and an error is logged in both the ACC and the engine control unit.
The cruise control will not be available again until the vehicle is restarted.
The supplier of the electrical kit (Jäger) insists that the coding is incorrect, but they cannot specify what is wrong with it.
Perhaps someone has time to review the code and check for any errors.
Of course, I am open to receiving any other information regarding the problem.
I have attached the Autoscan results here.

Sure, here's the translation:

"Thank you very much in advance."

Best regards, Marco.

It doesn't work like that because the probability of someone having the exact same car with the exact same coding as yours is very low.

The error in the distance control system is a secondary error resulting from an entry in the engine control unit, which reports an inappropriate message.

Either the engine control unit is incorrectly programmed (check the programming), or possibly... Post a Screenshot of your available options in VCDS, or your trailer control unit is sending a message that the engine control unit cannot process, even with the correct coding.

Hello Rainer,

You're very welcome for the quick response.
I have rechecked the engine control unit, and according to the selection in the long coding help, the trailer hitch is activated.

I've attached pictures of all the available options for your consideration, just to be sure.

Regarding coding, I once received a document for the B8 S4 that clearly showed how each control unit needed to be coded. So, I was wondering if anyone here might have something similar for the Q5.

My suspicion is still that the trailer control module is responsible for the error, but I would appreciate a brief confirmation that you would also confirm that the coding in the engine control unit is correct.

You're welcome.
Best regards,
Marco Isler.
