my BMW 330 has all three lights on, brake, tire and traction control.
I think it is the steering sensor because my headlights no longer move when I turn the wheel. also had codes checked and no codes.
the other thing is all 3 come on when the car is started, before it has moved but I DO get a beep just after moving like there is another fault.
the steering angle sensor SAS has to be calibrated if replaced. also I could try recalibrating it. I saw these OBD scanners that can do but I would also like to be able to look at live data when driving.
what do you think of these 2

much more expensive but if I have to pay someone to calibrate the SAS this one may be worth it, but not sure what else I get for the $$
