Headlamps with High Intensity Gas Discharge (HID) Lamps General information
Headlamps with High Intensity Gas Discharge (HID) lamps have "Bi-Xenon" function. In a standard "Xenon" system, only the low beams use HID bulbs. In a "Bi-Xenon" system, a single HID bulb is used for both low beam and high beam functions. This is accomplished through use of electro-mechanical headlamp adjusters ( Left Headlamp Reflector Adjustment Solenoid N395 and Right Headlamp Reflector Adjustment Solenoid N396 ) that tilt the HID bulb reflectors to refocus the light beam during high beam operation. For this reason, high beam is also adjusted automatically with low beam for "Bi-Xenon" headlamps. High beam operation is supplemented with a separate Halogen bulb and projector lens. HID headlamp system uses an automatic vertical headlamp beam adjustment system to minimize glare for oncoming traffic. Before troubleshooting or servicing, technicians must be familiar with the functions and operation specifics of the standard or optional headlamp or lighting system. Always read the owners manual and review applicable system functions. Note:

HIGH VOLTAGE!
Headlamps with High Intensity Gas Discharge (HID) Lamps
The physical and mechanical properties of HID bulbs are very sensitive. Internal pressure of HID glass bulb may exceed 100 bar (in operation). Bulb temperature may exceed 700 degrees Celsius.
The control modules for HID lamps must never be operated (headlights turned on) without an HID lamp. HID bulbs must only be operated (headlights turned on) when installed in the headlight housing.
Always wear safety glasses and gloves when removing and installing HID bulb.
Never look directly at an operating HID bulb. The UV emissions of an HID bulb are approximately 2.5 times that of a comparable halogen bulb.
Caution! Before servicing headlamps:
Switch off all electrical consumers.
Switch off ignition and remove ignition key.
Headlamps with High Intensity Gas Discharge (HID) Lamps - On Board Diagnostic (OBD), function
HID headlamp functions are monitored by Vehicle Electrical System Control Module J519 which has On Board Diagnostic (OBD) capability. If malfunctions occur in monitored components, Diagnostic Trouble Codes (DTC) will be stored in memory. In addition, the Troubleshoot headlamp system malfunctions by performing OBD program using VAS 5051/5052 Tester in operating mode "Guided Fault Finding" . Automatic vertical headlamp beam control - On Board Diagnostic (OBD), function
HID headlamps operate in conjunction with the automatic vertical headlight beam adjusting control modules which are controlled by an internal microprocessor with On Board

Vehicle Level Sensors, servicing
Headlamps with High Intensity Gas Discharge (HID) Lamps
General information
Vehicle level sensors transmit a Pulse Width Modulation (PWM) signal (representing vehicle attitude, load etc. ) to the appropriate system control module. In order to generate this PWM-signal, voltage is supplied to the Left Rear Level Control System Sensor G76 via two plus-wires and one Ground (GND) wire. Voltage is supplied to Left Front Level Control System Sensor G78 via one plus-wire and two Ground (GND) wires. Note:
Additional information

Vehicles without Air Suspension
A vehicle level sensor is located on the front axle ( Left Front Level Control System Sensor G78 ) and rear axle ( Left Rear Level Control System Sensor G76 ). The vehicle level sensors are a component of vertical headlamp aim control system. The vehicle level senors transmit their signal to Left Headlamp Range Control Module J567 and Right Headlamp Range Control Module J568 .
