CAN Bus: Sending Data to Audi FIS Display.

Hello,

ich frage mich, ob es schon eine Möglichkeit gibt, Daten über den CAN Bus an den obersten FIS Teil (da wo die Sendernamen vom Radio stehen) meines Audi S3 8L zu senden und über die 'Auf/Ab' Taste der FIS-Wippe am Lenkstockhebel zwischen verschiedenen Anzeigen im oberen Bereich zu wählen?

Es I'm looking to build a boost pressure and oil temperature display for my car that outputs the data directly through the FIS (FahrInformationsSystem). There's already a similar display available for vehicles with a 3LB (likely referring to a specific engine management system), but unfortunately not for CAN (Controller Area Network) based systems.

If anyone has specific information on how to access the top lines of the FIS and how to implement the up/down commands from the steering wheel controls so that I can switch between different displays (boost pressure, oil temperature, radio station name), I would be very grateful for any information on the subject.

Is there perhaps already a device that combines these functions and only needs to be fed with data?

Thank you and best regards,
