BMW E65 E66 Steering Column Control Angle Sensor Module 6771415 – Original Used Part

Diagnosis and Common Symptoms

The Steering Column Control Module (SZL) is a critical failure point in the E65 and E66 7 Series. When the internal optical sensor or electronic circuitry degrades, the vehicle loses communication with the Dynamic Stability Control (DSC) system. Common symptoms include the DSC/ABS warning light illuminated on the dashboard, the "Drive Control System" error message, and the failure of turn signals to automatically cancel after a turn. You may also experience heavy steering or the loss of active steering functionality. Diagnostic scans typically reveal fault codes 5E40 (Steering Angle Sensor Signal), 94B5, or 94B6, indicating internal hardware failure.
