Special tools and workshop equipment required
- Torque Wrench 1331 5-50Nm -VAG1331-

Removing
Note
- Applies to vehicles equipped with dynamic steering:
- Before the steering wheel can be removed from the steering column, the steering wheel must be in the exact horizontal using the Steering Wheel Scales -VAS6458-. Mount the new steering wheel so that it is horizontal using the Steering Wheel Level -VAS6458-.
