I have a BMW E46 with EOM xenon headlight, but they stopped working. I checked and BMW xenon headlights have two pieces: balast and igniter. Is it possible to determine which one is broken?

I added the scheme: Scheme of BMW E46 EOM xenon headlights

balast is 15, igniter is 16

Did both sides stop working?
If yes, it could be the module that sits behind the headlight switch.
If no, then switch the igniter or balast from left to right to find the culprit.
