Xenon Headlight Replaced, not working!

[North Idaho X5]

(2006 X5 E53 M54) The driver side xenon went pink, then blew a few days later. Per BMW manual, I lowered the bumper cover, took out both headlight assemblies. Opened rear cover, removed ballast and replaced bulbs on both. Passenger side is fine, but now the driver side won't light up. To test, I swapped ballasts and bulbs from driver over to passenger side and visa versa, passenger side still works fine, driver side still wont work. (New bulbs are Philips D2S #85122)
Halogen, angel eye and turn signal - parking lights are working fine on both, but the driver xenon side just wont work. The headlight assembly and wiring plug in wasn't mishandled, dropped or otherwise damaged.

I can't find a fuse or relay label for headlamps. What possibly could be wrong??

Please help me, I'm trying to avoid going to the local stealership.


Thank you!
