   • With wheel bolt adapter and measuring paddle
2. Calibration Tool - Wheel Center Mounting :VAS 6350/1A 
   • With wheel bolt adapter and measuring paddle
3. Right Catch Bracket
   • To mount the Spacing Laser :VAS 6350/2A  for the distance measurement
4. Plastic Foot
   • Quantity: 3
   • Adjustable for aligning horizontal position of the calibration board
5. Calibration Tool - Linear Laser :VAS 6350/3A 
   • With "laser protective eyewear"
   • On the calibration board
   • Refer to Calibration Tool - Line LaserVAS 6350/3A Owner's Manual for handling.
6. Calibration Tool - Spacing Laser :VAS 6350/2A 
   • For distance measurement
   • Refer to the Calibration Tool - Spacing LaserVAS 6350/2A Operating Instructions for handling.
7. Level
   • On the calibration board
   • For checking the horizontal position
8. Left Catch Bracket
   • To mount the Spacing Laser :VAS 6350/2A  for the distance measurement
9. Calibration Board
   • Between the catch brackets on the calibration board and the Calibration Tool - Wheel Center Mountings :VAS 6350/1A  , dimension -a- 1.40 m (4.6 feet) through 2.00 m (6.6 feet).

Requirements

• Create a work surface that is large enough (no objects surrounding the calibration board to prevent any incorrect line detections).
• Prevent any strong lighting contrasts (no headlamps or direct lighting).
• Move the vehicle onto a solid, flat surface.
• Move the wheels so that they are straight.
• Do not load the vehicle.
• Deflect and swing out the vehicle multiple times.
• Electromechanical parking brake applied.
• People must not sit in the vehicle.
• All vehicle doors and the rear lid must be closed.
• Clean the camera lens with a damp cloth.
• Connect the battery charger for the battery support mode. Refer to BATTERY, CHARGING .
• Before starting the calibration/adjustment, check the DTC memory and correct all displayed entries.

Procedure 

-- Check which hole circle the rims have.

-- Secure three suitable wheel bolt adapters for the wheel bolts on each Calibration Tool - Wheel Center Mountings :VAS 6350/1A  .

-- Insert the measuring paddle at both Calibration Tool - Wheel Center Mounting :VAS 6350/1A  and secure with the locking nut.

-- Place the Calibration Tool - Wheel Center Mountings :VAS 6350/1A  onto the wheel bolts on both rear wheels.

• The wheel center mounting rotation center must be in the wheel rotation center.

-- Place the Calibration Tool - Wheel Center Mounting :VAS 6350/1A  on the wheels so that any anti-theft wheel bolts are not connected to the wheel center mounting.

-- Adjust the measuring paddle using the locking nuts so that they move freely just above the floor.

• The measuring paddles must move easily.
• The measuring paddles must be vertical.

-- Position the calibration tool at distance -a- to the rear wheels.

• Dimension -a- = 1.40 to 2.00 m (4.6 to 6.6 feet)

-- Using the bubble level (level indicator) -arrow-, bring the calibration tool into a horizontal position by turning the plastic bases.

-- Wear "laser protective eyewear".

-- Turn on the Calibration Tool - Linear Laser :VAS 6350/3A  -item 1- on the calibration tool.

-- Align the calibration tool so that the Calibration Tool - Linear Laser :VAS 6350/3A  strikes the center of the emblem on the rear lid.

Distance measurement to rear wheels:

-- Switch on the Calibration Tool - Spacing Laser :VAS 6350/2A  .

• -Arrow 1- : position with front edge
• -Arrow 3- : position with rear edge

-- Press the corresponding button.

-- Hold the Spacing Laser :VAS 6350/2A  -item 2- for the distance measurement on one side of the calibration board flush to the catch bracket, as shown.

Courtesy of AUDI OF AMERICA, LLC

• The Calibration Tool - Spacing Laser :VAS 6350/2A  must lie firmly against the catch bracket.

-- Push the measurement button briefly.

• The laser switches on.

-- 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, then correct the measuring paddle height using the clamping screw on the Calibration Tool - Wheel Center Mounting :VAS 6350/1A  .

-- Use one hand to hold the Calibration Tool - Spacing Laser :VAS 6350/2A  firmly in the catch bracket on the calibration tool the laser beam should be seen on the measuring paddle during this.

-- Then press the measurement button for the distance measurement briefly.

-- Note the value.

-- Repeat this measurement on the other side of the calibration tool in the same way for the rear wheel.

• The distance value must be the same on both sides.

-- If both measured values are not the same, then readjust the calibration tool correspondingly until the distance values are the same on both sides.

-- Make sure the Calibration Tool - Line Laser :VAS 6350/3A  strikes the center above the emblem and that the level indicator remains centered. Adjust if necessary.

Calibration tool -1- distance measurement to workshop floor:

-- Measure the distance from the upper edge of the Calibration Tool to the floor, dimension -a-.

-- Make sure the Calibration Tool - Spacing Laser :VAS 6350/2  is set correctly (attached to the front edge).

• -Arrow 1- : position with front edge
• -Arrow 3- : position with rear edge

-- Press the corresponding button.

-- Then press the measurement button for the distance measurement briefly.

-- Note the measured distance from the upper edge of the calibration tool to the floor.

Height measurement from center of rearview camera lens to the wheel contact surface:

-- Use commercially available measuring tape to measure the height from the center of the rearview camera lens to the wheel contact surface.

-- Mark the determined height.

The determined distance and height dimensions must now be entered in "millimeters" in the Vehicle Diagnostic Tester.
