WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2018 Audi S8, 2018 Audi A8 Quattro, 2017 Audi S8, 2017 Audi A8 Quattro, and 2016 Audi S8. However, it is still accessible from the selected car via links, so may be relevant.

General Information

Vehicles with level control and/or HID headlamps have standard automatic headlamp range control. Refer to Headlamp, Adjusting .

To function properly, the level control and automatic headlamp range control system need information about compression travel or rebound travel at the front and rear axles.

For this, the position of the left/right lower transverse link in relation to the body is transferred via a coupling rod to the Left Rear Level Control System Sensor -G76- and Right Rear Level Control System Sensor -G77-. These transmit electrical signals to the Level Control System Control Module -J197- -item ) OVERVIEW - ELECTRONIC DAMPING - List Item:Level Control System Control Module -J197-.

The signals from the Left Front Level Control System Sensor -G78- and the Right Front Level Control Sensor -G289- are transmitted to the Level Control System Control Module -J197- -item ) OVERVIEW - ELECTRONIC DAMPING - List Item:Level Control System Control Module -J197- at the rear axle.

These signals are required for determining vehicle level.

The system reacts on its own to the changes in the vehicle level and evens it out.

The vehicle level can change in the following situations:

Trailer Mode
Different load conditions; vehicle empty, vehicle partially or fully loaded

NOTE:

Adapting control position and checking headlamp basic setting is necessary if

the lower transverse link has been removed and reinstalled or replaced
the subframe was replaced,
Installation work has been performed on the level control system sensor,
the level control system sensor has been replaced,
The level control system sensor coupling rod threaded connection was loosened at the lower transverse link.
The Level Control System Control Module -J197- was replaced.

Requirements

The vehicle must be standing on an even surface.
The vehicle may not be loaded.
