General notes

After replacement of the steering, the end stops of the steering box have to be relearned. Incorrectly learned end stops can lead to sudden elimination of the steering servo in the end stop.

The following preconditions must be met on learning the end stops:

1. Vehicle parked on a level surface.
2. Front wheels free for steering wheel movements.
3. Engine running.
4. Vehicle stationary.
5. Brake pedal not pressed and parking brake not engaged.
6. No fault entry in the dynamic stability control (DSC) and the steering column switch cluster (SZL).
7. Indicator light and Check Control symbol light up in the instrument panel.
8. Steering wheel in straight-ahead position.

On learning the end stops, the steering wheel must be fully turned slowly once to the left and once to the right. The steering speed must be below 1 steering wheel turn per second. In the end stops, slowly increase the steering force until the steering wheel no longer turns.

Then return steering wheel to its center position and let go of the steering wheel.

After approx. 5 seconds, the indicator light and Check Control symbol in the instrument panel go out.
