Field 2: Steering Torque Sensor (G269)
Turn the Steering Wheel multiple times completely to the left and right. The Torque Values should change.
If the Torque Values do change, it's most likely an intermittent Fault in the Wiring/Connectors.
If the Torque Values do NOT change, the Sensor itself or the Power Supply (Terminal 15) might be faulty.

Replacement
After Replacing this Control Module several Steps have to be performed in the following Order:
Check/Update Steering Aid Adaptation Channels 002-009
Perform Basic Setting for Steering Angle Sensor (G85)
Perform Steering Limit Stop Adaptation
Upload/Install a proper Characteristic Curve
Characteristic Curves need to be uploaded with the Factory Tool which has the latest Brand Version installed as well as access to the latest Flash Updates. Unless you have a Factory Tool which meets these Requirements the only Solution to accomplish this Step is to take the Car to the Dealer and have them perform this.
