Replacement of steering angle sensor

The steering angle sensor forms a unit with the steering column switch cluster. The steering angle sensor cannot be replaced on its own. The service function "Adjustment steering angle sensor" or in the case of vehicles with active steering the service function "Commissioning/aligning active steering" must be run after the following work:

• Replacement of steering column switch cluster (SZL)
• only E60, E61, E63, E64: programming steering column switch cluster (SZL in the E70 and E71 not programmable)
• only E70, E71: replace DSC control unit (because the DSC synchronizes the SZL)
• Adjusting procedure on the steering geometry
• Work on the steering and/or front axle
