My son's 2002 turbo beetle has an intermittent problem with the battery discharging every three or four days. I had the car running in the driveway for an hour and no problem. I turned it off and restarted the motor and the battery light came on. I turned it off and back on and the light was not on. It has a new alternator and battery in it already. I beleive my son even took the alternator back and exchanged it for another new one just to make sure it wasn't the alternator. The battery is a month old. Could someone tell me how many different ways there are to trigger this battery light to come on. I had all the instrument lights come on and off one time when I started it, but just that once. I welcome all suggestions no matter how crazy they might be. Thanks.
