Special Notes
Some of the Bosch 5.7 modules will not show live Steering Angle Sensor (G85) readings after the Login and Coding are performed. If this is the case -2.5 ° may be stuck in Measuring Block 005 and will not change when the wheel is turned. Make the wheels as straight as possible and continue with the Steering Angle Sensor (G85) Calibration.
