Why is my Audi A1 engine overheating?

I recently bought a used Audi A1 and I've noticed that the engine temperature gauge is often reaching the red zone. What could be causing this and how can I prevent it?

It's important to first check your coolant levels as low levels can lead to overheating. Also, check for any leaks in the cooling system. If everything seems fine, it could be an issue with the thermostat or the water pump.

I had a similar issue with my Audi A1 and it turned out to be a faulty sensor. It's always a good idea to have a mechanic check for any error codes to pinpoint the problem.
