What is the most common issue with the Audi A1's cooling system?

I've noticed that my Audi A1's cooling system is not working properly. What could be causing this and how can I fix it?

The most common issue with Audi A1's cooling system is a faulty thermostat. It can cause overheating and potential engine damage.

Another possibility could be a leak in the radiator or the water pump. I suggest getting it checked by a professional mechanic.

Make sure to regularly check the coolant level and top it up if needed. Low coolant levels can also cause cooling system problems.
