I have a 2009 A4 2.0T. The Vehicle Light (Bulb) Malfunction indicator light comes on intermittently. Should there be a way for me to see which bulb is having issues? I know some models will tell you exactly which light it is, but I can't seem to find where on my car it does that. When I've checked, all of the lights seem to be working properly.

Thanks,
H.
