    I thought it would be a rev limit light, but surely that would be with the rev counter not the speedo, plus ive hit the limit and its never come on, could be a covert Audi cam lol spying on us all. Cant find anything on google about it either,

    Just wondered, as if it's redundant (an old alarm indicator for example) I may have another use for it...

    Light sensor. On the 8p it is below the 160 on the speedo and I can't see it on this pic.

    Just a thought

    panic light.
    It comes on in my car when I lose grip on 60+mph corners.

    very distracting!

    I know it's a plastic cap with an led mounted to the pcb underneath. As nearly lost it when was replacing my LCD display. No idea what it's for tho lol.

    I read in the handbook that can set a speed limit warning? Possibly related?

    Its a light sensor.

    It dims and brightens up the display/LEDs when you go in a tunnel or bright light.

    It does it ever so slightly.

    If you watch the illumination on your dials and put your hand over it, it will change.
