Hello everyone.
I installed a Westfalia wiring kit for a tow hitch on my Seat 5F, manufactured in 2017.
Unfortunately, I can't get rid of the "ACC not available" message.
Error in ACC module: Missing message on data bus.

Does anyone have a wiring diagram for a trailer hitch for this vehicle?

Hi.

"Autoscan is missing... Was my link working?"
/viewtopic.php?t=28734
Read?

It turned out that the problem was with the trailer control unit.

Best regards, Rainer.

Hello Rainer,
I will add the car scan information.
I read the other post.
I think I will change the coding in section 13 as described.

Can the control unit become unusable if you enter an incorrect code?

Best regards, Stefan.
