Dash warning symbols

[Slartibartfast]

Okay, after a bit of searching I found what appears to be a similar looking symbol for BWM dashboards:

Apparently this means: "Exterior Light Fault"

Is there really nowhere that these symbols are listed?

Traction control malfunction light? it should have stated what the problem was in the information tray.

I get this one a lot myself. What causes this? Air in the ABS modulator or some bug in the system?
