On US spec 128i's xenons were optional. In the rest of the world... they had three headlight options for all 1er's... Halogens, Xenons(inner lens are clear) and AHL Xenons(inner lens is opaque).
What's not OE are those purple(?) finned alu ballasts wired into the back of your headlights. Looks like whoever did the wiring job, never bothered to put back the headlight covers(behind the headlights) and that allowed moister into the headlights. When that happens it can blow out(up) the footwell module AND/or the internal wiring inside the headlight. New headlights are about $700 per side. A footwell module is a few hundred - plus it will need to be coded to your car.

Excellent clarification. Thank you. That's what's so confusing about this is WHY those finned ballasts/bulbs were put in by the PO if there were already Xenons in there (I've seen people do that, of course, to go from Halogen to Xenons).
The covers were on and on tight but who knows if that's always been the case.
