Measurement Preparations For Axle Alignment - Complete Alignment Mode

The mode "complete alignment" must be selected on the Wheel Alignment Computer if an axle alignment must be performed together with the driver assist systems adjustment/calibration.

Special tools and workshop equipment required 

• Wheel Alignment Computer released by VW/Audi
• Vehicle Diagnostic Tester
• Brake Pedal Actuator:V.A.G 1869/2  .

Measurement Preparations

• Drive the vehicle onto the alignment rack without tension. Move the vehicle back and forth if necessary to relieve any tension on the axle components.
• Switch off the ignition when the vehicle has come to a stop.
• Vehicle accurately aligned, suspension bounced and rocked several times
• The steering wheel must be "evened out" into the center position before beginning the axle measurement and adjustment. Use Steering Wheel Scales:VAS 6458  for this.
• Make sure that the sliding plates and turn tables are not touching the end stop when checking the wheel alignment.
• The measurement sensor must be properly adjusted and attached to the vehicle; observe device manufacturer's operating instructions.
• Perform wheel run-out compensation: permissible axial run-out of the wheel rims can exceed the specified toe setting tolerance. If compensation for wheel run-out is not performed, it will not be possible to obtain a correct toe-in adjustment.
• The alignment rack and wheel alignment computer can deviate from their original calibration over time; therefore, they should be calibrated at least once a year during maintenance.
• Handle highly sensitive units with care.
• If necessary, contact the manufacturer for instruction on the proper use of the equipment.
