Headlight screen adjustment solenoid

With conventional xenon headlights, the gas discharge bulbs only

generate the dipped beam. The „bi-xenon“ features makes it pos‐

sible to generate both the dipped beam and the main beam with

„one“ gas discharge bulb. To achieve this, an electromechanical

adjuster ( left headlight screen adjustment solenoid -N395- / right

headlight screen adjustment solenoid -N396- ) uncovers the

screened area of the dipped beam on actuation of the main beam

function, thus producing main beam light distribution.

4.11.1

Removing and installing headlight

screen adjustment solenoid

The headlight screen adjustment solenoid on left -N395- / head‐

light screen adjustment solenoid on right -N396- are located

inside the respective headlight and can neither be individually re‐

newed nor adjusted.
In the event of damage, the headlight must be renewed

⇒ page 280

 .

4.11.2

Testing headlight screen adjustment

solenoid

The left headlight screen adjustment solenoid -N395- / right head‐

light screen adjustment solenoid -N395- can be checked using

the final control diagnosis of the onboard supply control unit -

J519- .
