    B7 Instrument Cluster - Backlit Scales not working with Headlights OFF

    Battery went dead on my B7 RS4 since I haven't driven it in a couple months. After getting the battery charged up and the car going again my cluster dashlights (scales) are not showing up unless it's sunny outside. The first day it was overcast and I only had the needles lit up.

    I have never had this issue in the past. My dash lights are always on and I never run with the headlight switch in the "Auto" position, it is always in the "OFF" position. When I open the door the lights come on in the cluster but after I shut the door they fade back to just the needles lit up.

    Of course when I turn on the headlights or parking lights the scales do light up but like i said I never had this issue in the past. I could be sitting in a parking lot at light with the engine running, no lights on and all my dash lights worked.

    I double checked with Vag-Com and my code was 31300

    17-Instruments:
    Mode 0: Nothing lit until ext. light on
    Mode 1: Pointers lit all the time
    Mode 2: Scales lit all the time
    Mode 3: Pointers and Scales lit all the time

    Changing the first number had the desired effect for 0,1,2 but when I switched back to 31300 I still only see the needles light up.

    Can't figure out WTF is going on here???

    Thanks,
