Why does the engine of my BMW 3 Series overheat?

I recently noticed that the temperature gauge of my BMW 3 Series has been going up to the red zone. What could be causing this issue and how can I fix it?

It is possible that your engine is low on coolant or there is a leak in the cooling system. I recommend checking the coolant level and if it is low, topping it off or bringing it to a mechanic for further inspection.

Another factor could be a faulty thermostat that is not regulating the engine temperature properly. This can cause the engine to overheat. I suggest having a mechanic check and replace the thermostat if necessary.
