Please help me figure out why both xenon D1s AHL headlights are not working on my 2008 328xi.

I saw a pinout in one of the threads that said pin 3 on the headlight connector is the the low beam xenon supply. I tested this pin with a DMM and got 12 volts when the switch is on AHL, and zero when it's not.

could it be both ballasts are shot? does coding have anything to do with it?
When I turn on the lights I hear the AHL motor adjusting but lights never worked.

Thanks.
