LEVEL CONTROL SYSTEM SENSOR
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. Refer to [For transmission(s) 02E] [For engine(s) CBRA, BPY, CETA, CCTA, CEPB, CDMA] General Information .
In order to function, the electronically-controlled damping (Audi magnetic ride) and automatic headlamp range control require information about the compression or rebound travel at the front and rear suspension.
For this, the position of the left/right track transverse link in relation to the body is transferred via a coupling rod to Left Front Level Control System Sensor -G78- and Right Front Level Control Sensor -G289-. These transmit electrical signals to the Electronic Damping Control Module -J250- and/or Left/Right High-intensity Gas Discharge Lamp Control Module -J343/344-.
Left/right high-intensity gas discharge lamp control module, servicing, refer to [For transmission(s) 02E] [For engine(s) CBRA, BPY, CETA, CCTA, CEPB, CDMA] Removal and Installation .
At the rear suspension, these signals are transmitted from the Left Rear Level Control System Sensor -G76- and Right Rear Level Control System Sensor -G77- 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 automatic headlamp range control reacts independently to changes in vehicle level.
The vehicle level can change in the following situations
- Trailer Mode
- Different load conditions; vehicle empty, vehicle partially or fully loaded
Vehicle level sensor is available as replacement part only complete with coupling rod and upper and lower retaining plates.
Note. Program the control position on vehicles with electronically-controlled damping (Audi magnetic ride) and check the headlamp adjustment if
Scheme 168
- Assembly work was performed on level control system sensor.
- The transverse link was removed and installed.
- The threaded connections -2- or -5- were loosened.
Removing
Disconnect the connector.
Remove nut -5-.
Remove bolt -2-.
Remove level control system sensor -3-.
Installing
Installation is performed in the reverse order of removal. Observe the following when doing so
The hooks on the coupling rod must be guided onto the transverse link.
Sensor lever must point outward.
Tightening specifications, refer to SUBFRAME, STABILIZER BAR, TRANSVERSE LINK, BALL JOINT, AND LEVEL CONTROL SYSTEM SENSOR ASSEMBLY OVERVIEW .
On vehicles with electronically-controlled damping (Audi magnetic ride), reprogram control position using VAS 5051B.
Perform headlamp basic setting. Refer to [For transmission(s) 02E] [For engine(s) CBRA, BPY, CETA, CCTA, CEPB, CDMA] Diagnosis and Testing .
