In Reply to: On board computer "hidden features"? posted by EricY on April 14, 1999 at 13:18:23:
I believe you have to press the odometer reset button (or was it the clock buton?) as you turn the key.
: Does anyone know the secret keystrokes to access any hidden features in the on-board computer? (If there are such things)
: I've read on a4.org that on an A4, by pressing some radio and A/C buttons you can actually get a numeric reading of all the sensors hooked up to the on board computer. Given that the A/C circuitry on E46 is derived from the Audi's (from earlier posts), E46 should have something similar.
