Hi i have a 2000 c230k with 90k miles. Its bas/esp light turns on when I press the brake when the car is moving over 20mph. The cruise control works. I replaced the brake switch and did the turning of the steering wheel full lock left anf right but still get the bas/esp light on. The car runs perfect though.

I used carsoft to check the codes and i got these:

How do I fix this? how can I test the steering angle sensor?
