BMW 750Li ABS light activation and turn signal malfunction after driving, possible steering angle sensor calibration issue on BMW 750Li

Some BMW 750Li owners report experiencing ABS light activation and turn signal malfunctions, which may be linked to steering angle sensor calibration issues. A failed or improperly calibrated steering angle sensor can trigger warning messages and cause the ABS light to illuminate. Additionally, incorrect calibration may result in off-center steering wheel problems and affect vehicle alignment. Owners should be aware that calibration is essential after maintenance tasks like wheel alignment or module programming. Some have found that a dirty steering angle sensor can cause the ABS light to activate randomly while driving or turning. Furthermore, moisture can interfere with sensor performance, leading to intermittent issues that might resolve after driving and restarting the vehicle. Utilizing diagnostic tools, such as a full system scanner, can aid in calibrating the sensor and identifying related error codes. It is recommended that owners experiencing these issues check and calibrate the steering angle sensor for effective resolution.
