keen 6 Report post Posted June 25, 2023 Some years ago I read about a battery saver device that turned the car light system off after about 15 min. This saved the batt from going flat if you left the boot not closed properly or hadnt shut a door properly. Does anyone know of this devise? Or is there something that can be fitted to the older cars for this purpose? Both my later models 320 and Mini have this type of system built in.
