Main headlights with gas discharge lamps (VW Touareg 1)

NOTE: The automatic headlight corrector with gas discharge lamps is equipped with a self-diagnosis function. When carrying out repair work, it is necessary to know how the lighting equipment works and how to operate it.

General description

The main headlights with gas discharge lamps have a "bi-xenon" function.

Gas discharge lamps in conventional "xenon" headlights emit only low beam. "Bixenon" allows "one" gas discharge lamp to produce both low and high beam. For this, an electromechanical regulator (magnet for moving the shutter in the left headlight and magnet for moving the shutter in the right headlight) when the high beam is turned on, the previously closed section of the low beam is opened and the high beam is distributed.

For this reason, in "bi-xenon" headlights, the high beam is automatically adjusted along with the low beam. However, if the car is equipped with "additional high beam", it should be adjusted separately.

European models

The low beam is produced by one light source.

The high beam is generated by two light sources.

Magnet for moving the shutter of the bi-xenon headlight

Gas discharge lamps in conventional "xenon" headlights emit only low beam. "Bixenon" allows "one" gas discharge lamp to produce both low and high beam. For this, an electromechanical regulator (magnet for moving the shutter in the left headlight and magnet for moving the shutter in the right headlight) when the high beam is turned on, the previously closed section of the low beam is opened and the high beam is distributed.

Removal and installation a magnet to move the bi-xenon headlight shutter

The magnet for moving the shutter in the left headlight and the magnet for moving the shutter in the right headlight are built into the headlight and cannot be removed and replaced separately or reconfigured.

In case of malfunction, the headlight must be replaced.

NOTE: The left and right headlamp swivel module position sensors are located inside the headlamp and cannot be replaced or adjusted individually.

NOTE: If faulty, the headlight must be replaced.
