It depends on weather it is the steering angle sensor or if its the brake switch causing you trouble... If the brake switch is the problem. (due to it just being bad and tripping the squiggly light) then it just needs to be changed... Its easy. take a couple minutes... If its the steering angle sensor that need calibrating then it just a couple mins with the laptop... However if it a bad steering angle sensor then the steering wheel comes off and the sensor is replaced and calibrated...
I've had my SL for one week, 175 miles and now the ESP light stays on shortly after starting the vehicle. Im not happy but I will be taking it to the dealership this week.
