Level Control System Sensor
Level Control System Sensor
Special tools, testers and auxiliary items required
• Torque Wrench 5-50 Nm (V.A.G 1331)
• Vehicle Diagnostic, Testing and Information System (VAS 5051)
General Information
Vehicles with electronically-controlled damping (Audi magnetic ride) and/or gas discharge lamps have an automatic headlamp range control system as standard equipment.
In order to function, the electronic damping (Audi magnetic ride) and automatic headlamp range control require information about the compression or rebound travel on the front and rear axles.
For this, the position of the left/right transverse link in relation to the body is transferred via a coupling rod to left rear level control system sensor (G76) and right rear level control system sensor (G77). These transmit electrical signals to the electronic damping control module (J250) and/or left/right high-intensity gas discharge lamp control module (J343/344).
At the front axle, these signals are transmitted from the left front level control system sensor (G78) and right front level control sensor (G289) to the electronic damping control module and/or the left/right high-intensity gas discharge lamp control module.
These signals are required for determining vehicle level.
The headlamp range control responds automatically to changes in the vehicle level.
The vehicle level can change in the following situations:
• Trailer Mode.
• Different load conditions; vehicle empty, vehicle partially or fully loaded.
• Program the control position on vehicles with electronically-controlled damping (Audi magnetic ride) and check the headlamp adjustment if:
• Installation work has been performed on the level control system sensor.
• The lower transverse link was removed and installed.
• Threaded connections - 2 or 3 - were loosened.
• The lower bracket for the vehicle level sensor is attached to the lower transverse link by two bolts - 2 - on vehicles with electronic damping (Audi magnetic ride).
• The lower bracket for the vehicle level sensor is attached to the lower transverse link with 3 bolts - 2 - on vehicles with headlamp range control.
The level control system sensor is only available as a replacement part together with the connecting link and upper and lower mounting plates.
- On vehicles with electronically-controlled damping (Audi magnetic ride), reprogram the control position using the (VAS 5051).
Removing
- Disconnect the harness connector - 1 -.
- Remove the screws - 2 and 3 -.
- Remove sensor.
Installing
Install in reverse order of removal. Note the following:
Tightening specifications => [ Bolt ] Level Control System Sensor Overview.
The sensor lever must face toward the outside of the vehicle.
- On vehicles with electronically-controlled damping (Audi magnetic ride), reprogram the control position using the (VAS 5051).
- Perform headlamp basic setting.
