Known CANID's

Below I have the (with me) famous CAN IDs that I measure on the Infotainment Bus of my Audi A4 B6 displayed.

The messages are 1 to 8 bytes long (00 01 02 03 04 05 06 07) and are usually Hexadecimal. On some identifiers are ASCII texts (readable content) displayed. Audi has a limited ASCII table. This I will also publish on the website.
