I have completed a master reset, and programming just the CAN-BUS works properly. When pressing the ignition button (push to start) the unit never goes red. (The documentation that came with mine shows a keyed unit, so I'm going by another guide I found saying to hold the fob up to the push-to-start button and push it twice.)
I have reprogrammed the unit a number of different ways (including everything off but the two 'recommended') and still no luck. Right now I have A3 A7 D6 as the only ones enabled and it still just stays yellow.
