Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, you may simply need to initialize the steering angle sensor.
Try starting the car and turning the steering wheel all the way to the left and then all the way to the right a few times and see if the light turns off.
If that fails you will need to have the traction control system scanned for fault codes. Most likely the fault will be with the steering angle sensor.
Let me know if you have any questions.
