  Note
t  Applies to vehicles with dynamic steering:
t  Before detaching it from the steering column, the steering wheel must be aligned accurately in a horizontal position using the steering wheel balance -VAS 6458-. Use the steering wheel balance -VAS 6458- to align the new steering wheel horizontally on the steering column.
t  After completing the above step, check the steering wheel position on the steering angle sender -G85-. To do so, select the corresponding measured value block in the self-diagnosis for the steering column electronics control unit -J527-. If the value displayed is > 0.5°, the steering angle sender -G85- must be re-calibrated and the dynamic steering re-adapted. To do so, select the corresponding program in Guided Fault Finding → Chapter.
