Description

Hacking into Audi A3 8P Driver Information System

README

Audi A3 8P Red FIS Project

This is a project about discovering (reverse-engineering) Audi A3 8P dashboard's Driver Information System and its protocol.

For people who don't know what is DIS or FIS: https://www.youtube.com/watch?v=bKFak5AGAGo

The goal is to implement a similiar but simpler open-source alternative to the "FIS-Control" or "Polar FIS". https://fis-control.de/index_en.html https://www.urotuning.com/products/polar-fis-advanced-multi-function-display-pf-04?variant=8384889323575

Compatibility:

Selectable in "menuconfig":

• You can use Alternative VWTP CANID if you have RNS-E (Audi navigation with color display) installed and your dashboards part number is "8P0 920 930". Don't select "FIS-Control" in your RNS-E custom firmware in this case. Enter/exit FIS scenarios are a bit buggy.

• You have to use Navigation VWTP CANID if you have dashboard with part number "8P0 920 931". Alternative CANID is not supported by the dash.

You may select "FIS-Control" in your RNS-E custom firmware in this case, and RedFIS will do the routing of the display data from RNS-E to the Dash - if that last "page" is selected using the Up/Down stalk buttons. This feature can be enabled (or disabled) in the menuconfig. Default state is enabled, since my car has a navigation with custom firmware and "FIS-Control" option enabled.

Brave volunteers are warmly welcomed for testing... :)
