Is your DRL option "on"? It sounds like it is not on. You can get the dealership to turn on the option. Otherwise, the only time the Daytime Running Lights come on is when you flash the brights, which would explain why that is the only time your Angel Eyes come on.
By the way, "flickering" is bad for CCFL lights. A lot of people connect their lights to the interior lights, which are on a fade circuit, and cause the CCFLs to flicker, or, if you use a relay in the light circuit, it will cause the relay to chatter.
Either way, the ballasts will try to draw way too much current and fail very quickly. If you want to connect to the fade circuit of the interior lights, use a relay, and stick a 220 mf 35V capacitor accross the relay coil. This will eliminate chatter and make the CCFLs only come on when enough voltage is present - they won't flicker or dim.
