Measurement Procedure

Measurement procedure

The following equipment is required:





^ Electronic wheel alignment unit; e.g. V.A.G 1813
^ Make sure that the sliding plates and turntables are not touching the end stop when checking the alignment.
^ Vehicle accurately aligned, suspension bounced and rocked several times
^ The test equipment must be properly adjusted and attached to the vehicle (see equipment manufacturers instructions).
- Perform wheel rim runout compensation.

Note: Compensation of wheel rim runout: A certain amount of lateral runout at the wheel rims is permissible, but this may already exceed the specified toe-in tolerance. In such cases it is not possible to correctly set the toe-in without performing the wheel runout compensation.





- Insert brake pedal depressor.

Overview of work sequence for measuring wheel alignment

Note: The vehicle must be unladen when measuring wheel alignment.

Observe the following work sequence
1 - Check camber at front wheels and center if necessary.
2 - Check camber at rear wheels.
3 - Check toe setting at rear wheels and adjust if necessary.

Vehicles with front wheel drive
- The toe setting at the rear wheels is not adjustable.

Vehicles with all wheel drive
- Toe setting is adjustable.
- Adjusting toe setting.

4 - Check toe setting at front wheels with vehicle unladen and adjust if necessary.
5 - If settings have been altered at the front wheels, perform zero position compensation for steering angle sensor G85 (only applies to vehicles with ESP).
