I have 2006 with 10/2005 production A6 3.2q S-Line
Have you checked the manual. The procedure is in mine but it's an older car
if its the same as the older models its a combination of pulling the trip knob and pressing the clock knob simultaneously with the ignition in the first position or something. or a vice versa approach till it resets.
If it's a new shape there is no possibility to reset it without diagnostic equipment.
BTW i can help ...
