Customer states:
• The vehicle pulls to one side.
And/or
•
The steering wheel is crooked.
Technical Background
This bulletin applies to axle alignment only.
Complaints regarding suspension which are not caused by a fault for which the manufacturer is responsible
cannot be billed under warranty.
For the reasons specified above, wheel alignment can therefore only be billed under warranty if specific
conditions are fulfilled.
Deviations of ±2° in the steering wheel position are within the permitted tolerances for the individual toe
settings and therefore do not constitute a fault.
When assessing the customer statement “the steering wheel is not straight or is crooked”, make sure that the
steering column is in the top position and is pushed as far as it will go toward the dash panel.
If the steering wheel/steering column is in a different position, there may be a misalignment within the tolerance of
±2°.

Background: When setting the axle geometry in production, this position is selected to reduce the influence of the
movement of the steering shaft joints on the steering wheel position.
Note:
During the production of Audi vehicles, only the total toe is considered and adjusted during the pre-assembly of
the rear axle. During a workshop visit, if the total toe is OK but one of the individual toe settings on the rear axles
is not OK, this is not a valid reason to perform wheel alignment under warranty.
Below are some examples of the Steering wheel off center by 2° to the left and 2° to the right. (Figures 1 to 5).

Production Solution

Service
Before every wheel alignment, proceed as follows:
1. Test drive the vehicle to reproduce the concern.
2. Pay attention to the road camber during the road test as this has a considerable effect on vehicle handling.
The vehicle will always tend to try to follow it.

3. Always hold the steering wheel with both hands; never attempt to assess whether the vehicle travels in a
straight line by taking your hands off the steering wheel. It is not possible to perform an assessment in this way
due to the low friction of the axle components and the design of the steering rack.
4. If the vehicle pulls to one side when accelerating or braking, this can also be caused by the tires.
5. Review the complaint according to Elsa at Repair Manual, Chassis >> Suspension, Wheels, Steering >> 44
Wheels, Tires, Wheel Alignment.
6. Use steering wheel scales VAS 6826 and VAS 6828.
7. Make sure that the software of the wheel alignment equipment is up-to-date.
8. Perform a wheel alignment only after excluding all other factors.
9. Perform an initial measurement during which you align the individual toe settings of the front wheels by turning
the steering wheel.
10. Take a photo of the misalignment of the steering wheel with the steering wheel scales attached.
11. Save the measurements and give this document an appropriate name (Ex: VIN + Initial measurements).
12. Now straighten the steering wheel and measure the individual toe values.
13. Also save these measurements and give this document an appropriate name (EX: VIN + Final
measurements).
14. Upload all documents related to the VIN to DOC-IT. (Only for vehicles at PDI and/or below 1000 miles).
