I have finally tried this, Skoda Kodiaq with a two spoke steering wheel with the travel assist button that I really thought was not even connected.
First I had:
A5 Driver Assistance - Long Coding - HC_Warn_Intensity - Setting_over_Menu (activates the Travel Assist menu in the interface)
HC_WARN_INTENSITY -> setting_over_menu
With this I had adaptative lane assist but the button on the steering wheel for travel assist did NOTHING and I had to nudgle the steering wheel every few seconds, very annoying.
And now I have added:
Control Unit 13->Long Coding-> byte 2 -> Capacitive_steering_wheel - Enabled.
A5 -> Hc_Variante: 2
A5 -> Klr: Enabled.
And the button now works!!! When you click it a 'Travel assist ' message comes on the dashboard.
The steering was capacititive, now I have to squeeze it only, not move it, it has to be squeezed more than for a example a BMW X5 but it does work.
And, BONUS TRACK, the lane assist now works at any speed, before it went off when below about 60kph.
This is my experience. The car really does not turn a lot though, any minor turn on any road will get you out in the field, it is really only good for very straight roads or motorway. This is the part I less like.
Hope this helps somebody....
