A3 L4-2.0L Turbo (BPY) (2006)
Alignment: Description and Operation
General information
Always measure wheel alignment using Audi-approved wheel alignment equipment.
Wheel alignment checks must always include both front and rear axles.
Otherwise, proper vehicle driveability cannot be ensured.
Note:
^
Wheels should not be aligned until the vehicle has been driven 1,000-2,000 km, since it takes this long for the coil springs to settle.
^
When making adjustments the relevant specifications must be adhered to as closely as possible.
^
Vehicle instability can also be caused by the wheels having a residual imbalance and/or radial runout which is too great.
CAUTION: After adjustment work performed on the front axle, calibration of the Steering Angle Sensor G85 and re-adaptation of the
steering must be performed on vehicles with ESP or ABS after vehicle alignment.
