BMW F10 xenon bulb replacement and common faults
F10 xenon light is reddish, is the fault in the ballast or the bulb?
A reddish light often indicates a worn or burnt-out bulb. When both headlight bulbs were replaced, the fault was fixed. Suspect the ballast (the bulb's power supply) only if a new bulb does not help.
How is the F10 xenon bulb replaced?
1. Turn the front wheel to full lock or remove the wheel to reach the service hatch in front of the front wheel. 2. Open the hatch by its two screws. 3. Turn the plastic cover counterclockwise to remove it. 4. Disconnect the connector and remove the bulb by turning it clockwise. Disconnect the battery negative terminal to be safe.
Is replacing the bulb different on the facelift (LCI)?
On the LCI model (model year 2015) the bulb is replaced through the hatch in the inner wheel arch with a special key, about half an hour per side. On the 2014 model this is not possible, and the headlight has to be removed, which is several hours of work for a first-timer.
How is the adaptive cornering light bulb replaced?
The adaptive lights have their own hatch, through which the cornering light's H7 bulb is replaced. If a fault message comes from the cornering light, the cause is often a burnt-out bulb rather than the swivel mechanism.
