Skoda Superb 3 T Facelift Towing Hitch Coding

Hallo, ich habe einen Superb 3T Facelift Modelljahr 2020. Ich habe jetzt eine Anhängerkupplung mit 13-poliger e-Satz von Bosal an diesem Fahrzeug montiert. Bis jetzt alles in Ordnung. Aber ich kann das Auto nicht auf die Anhängerkupplung einstellen. Can anyone help me and provide me with the information on what I need to refactor?

I installed the trailer hitch on the gateway.

In the engine control unit, I had programmed them, and in the brakes, I had performed the trailer stabilization, etc. Afterwards, nothing really worked in the car anymore. The trailer hitch did not transmit any bus information. The error message was stored. No communication. Everything has been re-coded, and the vehicle is now functioning again.

In the attachment is a dump of the error memory.

Hello

What happens if you activate the trailer ECU in the gateway?

Your car scan is unfortunately quite useless if you only post the functional original state. Should we guess what you have set up for each task?

Then there's the error that the trailer control unit is not establishing communication.

I have re-checked all the connections and pin configurations. I suspect that the problem may be with the AHK (Audio/Head Unit) control unit.

After some thought and searching, I found the error. The connection from the permanent power supply at the fuse box was loose. Just reconnected and the error is gone.

How embarrassing.

But what exactly do I need to recode in order to accommodate the trailer hitch?

Hello,

ok, vielen Dank für die Rückmeldung!
