Headlights
HeadlightsThe (E85) Z4 headlights are fitted with halogen bulbs as standard for both the dipped and main beams. Bixenon bulbs are available as an option. The bixenon headlights come with automatic beam height adjustment, while the halogen headlights have manual beam height adjustment.
There is a completely new procedure for replacing the bulbs. On the (E85)Z4, the bulbs are only accessible through a hole in the wheel arch liner.
The headlights are adjusted from inside the engine compartment through the crossmember using an Allen key.
The headlight lenses can not be replaced individually. They are permanently glued to the headlamp unit outer casing.
The headlight beam height positioner can be removed through the open cover when the headlight unit has been removed. Removal of the headlight beam height positioner involves threading it through the joint socket. On the dynamic positioner, the connector can be unplugged; on the manual positioner, the cable has to be cut.
