I spent $80 on a new sensor from the dealer to replace one the tire changer broke the top edge. They told me to air it up and it will reset with the new calibration once it goes 20 MPH, So wrong. Now I read that the dealer has to program the new sensor. Such BS, I hate making all the arrangements to leave the car at the dealer so I have been driving with the light on for months now. Anyone know a less painful way ?
