Golf 6 Instrument Cluster - Simulating Speed

Hello everyone,

Now that I've acquired a Golf 6 instrument cluster (KI), I can easily access almost all CAN functions. (The CAN USB adapter is connected directly to the KI).
The only major issue remaining is the vehicle speed.

While I have the correct CAN ID and data format, it seems the AI is performing a plausibility check using the distance signal.
This causes the AI to react correctly to my speed signal, but the pointer flickers and sometimes resets to 0, where it also remains.
Can someone explain how this distance signal works? What exactly do I need to send to the AI? Does the timing matter? Or the data? Beides?

Furthermore, while experimenting with the settings, I apparently activated some kind of "speed warning" feature. Whenever I set the speed above approximately 15 km/h, a small symbol appears in the MFA (Multi-Function Display).
Kennt jemand zufällig die Id zum Deaktivieren?
I also probably "activated" something with the tire pressure monitoring system, and now the warning light for it is just flashing (before everything was working correctly). I think I probably accidentally started the calibration, which is failing due to implausible data?

Gibt es hier jemanden, der Zugang zu Golf 6 Traces hat?

Liebe Grüße,
Fabian.
