10.4.2 Calibration Preparation Work

Special tools and workshop equipment required 

• Calibration Unit - VAS6350A-
• Vehicle Diagnostic Tester

Various preparation work procedures must be performed before the actual calibration procedure. Refer to Vehicle Diagnostic Tester.

Requirements: 

• Move the vehicle onto a secure flat surface.
• Apply the parking brake - the vehicle must not move during the measurement.
• Place the front wheels in a straight-ahead position - steering wheel neutral position.
• No persons may be in the vehicle interior during the measurement.
• Do not open and close the vehicle doors during calibration.

Procedure 

• Connect the Vehicle Diagnostic Tester.
• Switch the ignition on.
• Tighten three wheel bolt adapters (17 mm) for the wheel bolts on each -VAS6350/1A-.
• Insert the measuring paddle on both -VAS6350/1A- and secure it with the locking nut.
• Place the -VAS6350/1A- onto the wheel bolts on both rear wheels.
  • The wheel center mounting rotation center must be in the wheel rotation center.

• Adjust the measuring paddles using the lock nuts so that they move freely just above the floor.
  • The measuring paddles must move easily.
  • The measuring paddles must be vertical.
• Position the -VAS6350A- at distance -a- to the rear wheels.
  • Dimension -a- = 1700 ± 2 mm

• Hold the -VAS6350/2- -2- flush against the catch bracket, as shown, for the distance measurement.
  • The -VAS6350/2A- must lie firmly against the catch bracket.
• Make sure the "laser beam" for the distance measurement contacts the lower enlarged part of the measuring paddle -1-.

  If that is not the case, correct the measuring paddle height using the locking nuts on the -VAS6350/1A-.

• Briefly press the ON  button for distance measurement.

  Display on the -VAS6350/2A-:

  • "1, 700 m" (specified value: 1700 ± 2 mm).
• Repeat the measurement procedure from the left catch bracket to the measuring paddle on left rear wheel.
  • The distance value must be the same on both sides.

  If both measured values are not the same, adjust the -VAS6350A- accordingly.

• Secure the -VAS6350/4- to the -VAS6350A- mount on the rear left.
  • When installed correctly, the vehicle electrical system voltage wire must be connected at the bottom left of the calibration device (as seen in direction of travel).
  • Dimension -a- = 656 mm (measured from upper edge of calibration device to workshop floor).
• The adjustment dimension is set with the test probe -arrow- on the base of the calibration device on the scale of the steel ruler -1-.
  • Left adjustment dimension = 618 mm (read on measurement scale -1-).
• Connect the -VAS6350/4- to the vehicle electrical system voltage.

• Using the bubble level (level indicator) -arrow-, bring the - VAS6350A- into a horizontal position by turning the plastic bases.
• Wear laser protective eyewear.

  NOTE: The vehicle in the illustration is only a basic outline.
• Turn on the -VAS6350/3A- on the -VAS6350A-.
• Align the entire -VAS6350A- so that the laser beam shines on the center of the vehicle rear above the VW logo.

• Check the distance on the left and right sides between the catch brackets of the -VAS6350A- and the measuring paddles -1- on wheel mountings again.
  • Specified value: 1700 ± 2 mm
