when you engage the "sport" mode, what does it do to the car. (what is differant from the normal mode). Also I fliped the swith for the sport mode and the light came on and was fine. When i left the store the light was off. so if fliped the switch on and off. the sport mode light came on for a second and went off. should the sport light be on as long as the swith is on? 2003 360 spider..
You can read the other thread for what it does. BUT, no it isn't normal to go on and off. If the switch is on it should stay on even if you turn the car off and start it again later. If that is really happening you need to start digging or get professional help. If you didn't throw any codes it is probably an electrical problem. Good luck.
