Symptom: I have no auto-steer with my S2.
Resolution: Check that the eDrive(TC) is powered on and both the power light and the S Present light are illuminated. You can access the “Service” menu and arrow down to “eDrive Setup” to see that the eDrive(TC) is connected and the version of firmware installed. Under eDrive setup ensure the correct vehicle type is selected. Try doing a steer test. If the steer test does not go left or right, verify cabling to the valve is not damaged. At the end of the valve cable, there are red LEDs that plug onto the solenoid- when you do a steer test, left or right should illuminate accordingly. Have someone watch the red lights while you perform a steer test. Proceed with ruling out cabling and solenoid.
