Hmmm, I dont know. My Z4 has xexon and they auto-adjust when you turn them on. If you have the money, upgrade to a xexon system. All i know is that these headlights are amazing. I have driven with halogen and some HID systems, none are like the xexons that came with my 04 Z4. Its like a spot light concentrated on the road. I would take it to a dealer and see what they can do.
