Whenever you see this message on your Porsche notification screen it means that the engine cooling system of your Porsche has a problem.I’ll explain why such Fault would even happens.

1. the car thermostat is broken or does not function properly.
2. the car fan is broken (sometimes it’s working and sometimes it’s not, for example it might works in a slowdown mode and vice versa. 
3. water / coolant radiator is leaking or you might have forgotten to fill your car with antifreeze liquid and have used only water for a long period of time. keep in mind that if you don’t use antifreeze liquid, your water pump might face a leakage.
4. the car water pump does not work properly and collapse the engine’s water stream.
