i keep getting the low coolant warning (kuhlwasserstand) when i start and shut off the car. It never comes on while the car is running and the car operates at normal temp. I topped off the radiator when the warning came on (only needed maybe 1/2 a quart), and it hasn't gone down since, but the warning keeps comming on. Do i have to reset the system or is the level sensor probably bad?
I would check the owner's manual, but it's in German, and i can't read it...
