What is the most common cause for overheating in an Audi 80?

I have noticed that my Audi 80 is overheating more frequently than usual. I have checked the coolant levels and they seem okay. What else could be causing this issue?

The most common cause for overheating in an Audi 80 is a faulty water pump. It is responsible for circulating coolant throughout the engine and if it fails, your car will quickly overheat.

Another possible cause could be a leak in the cooling system. Check for any visible leaks or signs of coolant on the ground.
