Before carrying out the adjustment, the vehicle must be moved and the light
module at the bottom of the right-hand A-pillar exposed. Disconnect white
2-pin socket housing (3) (Dummy, green wire) from branch A2, white 2-pin pin
A
housing of xenon headlight wiring harness A and connect white 2-pin socket
housing branch A3 (wire jumper, red wire) kept in the glovebox to branch A2,
white 2-pin pin housing of xenon headlight wiring harness A.The vehicle should
be parked unladen on a flat and even surface for the purpose of automatic
adjustment of the level sensor. Disengage gear or selector lever in position "N".
Release handbrake and start vehicle. Make sure that the battery voltage is not
below 13.0 V for the adjustment of the level sensor (battery must be charged).
Disconnect branch A3, white 2-pin socket housing (wire jumper, red wire) from
F 39 0221 B
branch A2, white 2-pin pin housing of xenon headlight wiring harness A.
If the message "check low beam headlight or the symbol" appears in the
instrument cluster display, it is possible that fuse (1) in the cold light scan
module (2) is defective (500 mA slow-blow fuse). After replacing the fuse, there
still may be a fault in the cold light scan module or in the xenon headlight
(replace cold light scan module or xenon headlight).

The level sensor in the rear right wheelhouse is checked as follows:
- Expose light module (1) in right-hand A-pillar
A
- Park unladen vehicle on flat and even surface
- Disengage gear, release handbrake
- Connect voltmeter between branch A6, yellow/red wire of xenon headlight
wiring harness A and ground.
- Start vehicle
- Measure voltage (setpoint 1.0 V)
- Luggage compartment laden with 150 kg (2 persons)
- The voltage value must increase (approx. 1.2 to 2 Volt) after 20 seconds.
- If the voltage does not increase, either the control rod is detached (fixed) or
F 39 0220 B
the control sensor is defective.
