What is the cause of the Audi A2 engine overheating?

I have recently noticed that my Audi A2's engine is overheating and I am worried about potential damage. Can anyone advise on the potential cause and how to fix it?

The most common cause of engine overheating in the Audi A2 is a faulty thermostat. It is a relatively simple and inexpensive fix, with replacements ranging from $50-$100. Make sure to have this checked and replaced by a trusted mechanic.

Another possible cause could be a malfunctioning water pump. If your car's coolant is not being circulated properly, the engine will overheat. This repair can be more expensive, typically ranging from $200-$500 depending on the mechanic and parts.

Check for any visible leaks in the cooling system, as this could be a sign of a crack or perforation in the radiator or hoses. Another important thing to check is the coolant level, as low levels can also cause overheating. If you are unable to locate any visible problems, take your car to a mechanic for a thorough inspection.
