Steering angle sensor diagnostics 1998 E320 W210

[chiwanga]

This car is throwing a code for the steering angle sensor. The sensor was replaced less than one year ago, with a new oem sensor. Is there any way to verify that the sensor is in fact the problem? They are over $400, so I really dont want to just guess. I am further worried, becuase I read a service bulletin from Mercedes saying that many times the code for steering angle sensor is not fixed by replacing the actual sensor.
