What can cause the engine to overheat in an Audi A3?

I've noticed that my Audi A3's engine temperature gauge is constantly high and the check engine light is on. What could be the cause of this and how can I prevent it from happening?

One possible cause of an overheating engine in an Audi A3 could be a malfunctioning cooling system. It is important to regularly check and maintain the coolant levels and ensure that all components of the cooling system are functioning properly. Additionally, a clogged radiator or faulty thermostat could also contribute to the engine overheating.

Another common issue that can lead to engine overheating is a faulty water pump. It is important to get the water pump checked and replaced if necessary, as it plays a crucial role in circulating coolant through the engine and keeping it at a safe temperature.
