Steering Angle Sensor Error
Recently I did some work on my 2013 c250 replacing the OEM ESL with an aftermarket emmulator, in order to do the job I had to remove the steering wheel and steering angle sensor. After completing the job and reinstalling the steering angle sensor and steering wheel I discovered I put the steering wheel on crooked, having to turn about 45 degrees to drive straight, then both my traction control lights came on, and my cruize control system says its inoperable. After work I removed steering wheel and straightened it out, but the traction control lights stayed on, the cruize control remained inoperable, and now the front left airbag light is now and horn is not working. I tried to reset my steering angle sensor once my steering wheel was aligned but have had no luck. I suspect the steering angle sensor, but am unsure. Has anyone had a similar issue? I would appreciate any help or advice.

Make sure all the connectors at the back of the steering angle sensor/clock spring/switch assembly (all one unit) is connected at the back.
Outside of that, was the clock spring turned while it was apart? Given the feedback of the horn not functioning, if it's not a connector issue, your clock spring is out of phase by >180 degrees, i.e. the ribbon is now torn from turning the wheel lock to lock.
