Dynamic Steering Basic Setting

Special tools and workshop equipment required 

• Wheel Alignment Computer released by VW/Audi
• Vehicle Diagnostic Tester

There Are Two Choices for the Basic Setting:

The "Complete Alignment"

This procedure must be selected for the following activities if a wheel alignment and basic setting should be performed.

• The rear axle toe was adjusted.
• The vehicle suspension was changed, for example changing from standard to sport suspension.

The "Quick Access"

This procedure should be selected for the following activities if only the basic setting will be performed.

• The Steering Angle Sensor -G85- was calibrated.
• The Active Steering Control Module -J792- was replaced,
• The steering wheel is crooked when driving straight.

TIP:

• Both procedures are programmed in the wheel alignment computer. The respective procedure is performed automatically. It is only necessary to select the appropriate program for the procedure that will be performed.
• If the basic setting should be performed, then the "quick access" mode must be selected.
• The procedure in the "quick access" mode is described in the following.

Procedure 

• Note the test requirements. Refer to AXLE ALIGNMENT TEST REQUIREMENTS .
• Measurement Preparations for Calibrating and Adjusting Driver Assist Systems. Refer to MEASUREMENT PREPARATIONS FOR CALIBRATING/ALIGNING THE DRIVER ASSIST SYSTEMS, QUICK ACCESS MODE .

-- Drive the vehicle "straight" onto the alignment rack. Switch off the ignition when the vehicle has come to a stop.

-- Versions with air suspension: initiate and lock standard vehicle height. Refer to STANDARD VEHICLE HEIGHT, INITIATING AND LOCKING .

-- Move the rear axle steering into the zero position using the Vehicle Diagnostic Tester. Refer to REAR AXLE STEERING GEAR, MOVING INTO ZERO POSITION .

• This is the only way to ensure that the rear axle steering is in the straight-ahead position.
