Here's the solution to the riddle:
The steering angle sensor (G85) was installed rotated by 360 degrees, which can be seen in the ABS control unit within measurement block 4.
-> Remove the steering wheel and rotate the steering sensor to the correct position, then reassemble everything.
Please provide the German text you would like me to translate into English.
Select STG 03 (ABS).
STG Login -> Function 11.
Login code: 40168
ECU sensor data blocks -> Function 08.
Measurement group 060 (sensor for steering angle - G85).
Turn the steering wheel at least 15° to the left and right, then return the steering wheel to its straight position. Now, perform the basic adjustment. Subsequently, check the zero position of the sensor in measurement block 4, value 1; the target value is between -1.5° and

.5°.
After the initial setup, drive a short distance straight ahead at a speed of 15-20 km/h; during this time, the steering angle sensor (G85) learns the straight-ahead position.
Go to default settings.
Okay, I'm ready. Please provide the text you want me to translate from German to English.
