I may have finally done it! I think I discovered an A4 feature I haven't read about here. <p>When you raise a window with the driver's door controls, the light illuminating that window's switch (on one of the other three doors) goes out. It doesn't happen when you lower a window. <p>The only explanation I can think of is maybe a passenger would catch the light going off in the corner of their eye. That way they'd be alerted to their window being raised. Seems like the window itself would be way more obvious.

I've seem many switches burnt out because the driver is trying to roll the window either up or down, and the passenger is trying to roll the window the other way.... so the window stays still while the switches fight it out. In this case, while the driver is rolling the window up, it disables the passenger switch so that it cannot function. Of course that doesn't explain why the light doesn't go off when you're trying to roll down the window.
