Could you see it at all? Did the Audi Red look like the rest of the instrument panel? That would be cool.
What if I took the red plastic sheets (used in those decoder toys) and placed it behind the screen and screwed it in?
I tested the display by taking a peice of plastic overhead and scribbled a red sharpy on it, then placed it over the amber
display and it actually matched the BMW amber/red. Will that cause any problems?

Would there be any way to purchase the red audi display separately?
