Note: Read the note at the beginning Section 5. When replacing xenon lamps, there is a risk of injury due to high voltage! Be sure to turn off the headlights and disconnect the electrical wiring from the battery. After replacing, briefly turn the headlight on and off to relieve residual voltage. As a safety precaution, wear shoes with rubber soles.

The low-beam/high-beam switching solenoid valve, the headlamp levelling module position sensor and the headlamp turning solenoid motor are built into the headlamp housing and cannot be replaced separately from it.
