Measure Preparations

Special tools and workshop equipment required 

• Brake Pedal Actuator :VAG1869/2 
• Steering Wheel Scales :VAS6458 
• Wheel Alignment Computer released by VW/Audi

• The measurement sensor must be properly adjusted and attached to the vehicle; observe device manufacturer's operating instructions.
• Make sure that the sliding plates and turn tables are not touching the end stop when checking the wheel alignment.
• 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.
• The steering wheel must be "evened out" into the center position before beginning the measuring and adjusting. Use :VAS6458  for this.

Perform the following steps using "quick access" if one or more driver assistance systems on the vehicle will be calibrated (without a previous axle alignment):

• Before driving the vehicle onto the alignment stand, make sure there is enough space between the vehicle and the calibrating device. The distance between the calibrating device and the vehicle: 120 cm ± 2.5 cm.
• If there not enough space, back the vehicle onto the vehicle alignment platform so that there will be enough space.
• Check the DTC memory and correct any malfunctions before beginning the calibration.
• Vehicle accurately aligned, suspension bounced and rocked several times
• Make sure that the sliding plates and turn tables are not touching the end stop when checking the wheel alignment.
• Connect the battery charger. Refer to BATTERY, DISCONNECTING AND CONNECTING .
• Position the front wheels so they are straight.
• Connect the Vehicle Diagnostic Tester to the vehicle and guide the diagnostic cable through the open window.
• The vehicle exterior lamps are off.
• All the vehicle doors are closed.
• Using the screen, turn on the calibration on the wheel alignment computer.
