Alignment: Description and Operation
Wheel Alignment General Information
Wheel alignment must only performed using VW/Audi-approved wheel alignment equipment!
Each time wheels are aligned, both front and rear wheels must be aligned.
Otherwise, proper vehicle driveability cannot be ensured.
Note:
^
Wheels should not be aligned until the vehicle has been driven 1,000 to 2,000 km, since it takes this long for the coil springs to settle.
^
The individual specifications should be followed as exactly as possible when making adjustments.
^
Vehicle instability can also be caused by the wheels having a residual imbalance and/or radial runout which is too great.
CAUTION
After making adjustments on the front axle on vehicles with ESP or ABS, the Steering Angle Sensor G85 must be calibrated and steering
must be readapted after vehicle alignment.

If the installed position of the rear axle and thereby the direction of travel of the vehicle are not considered, a crooked steering wheel may result.
Steering wheel and steering column are marked. These positions must not be changed!
A - Marked line on steering wheel
B - Punch mark on steering column
Otherwise centering of toothed shaft cannot be guaranteed!
Steering columns supplied as a spare part do not have a center punch mark.
If the steering column or steering wheel is replaced, marking should be remade after alignment and road test.
