How do I maintain my Audi A2's engine temperature?

I've noticed that my Audi A2's engine temperature is fluctuating. What could be causing this and how can I make sure it stays at a consistent level?

Your Audi A2's engine temperature may be fluctuating due to a faulty thermostat or a cooling system issue. It's important to get this checked by a mechanic to prevent any potential damage to your engine.

To maintain a consistent engine temperature, make sure to regularly check and replace your coolant and keep an eye on your temperature gauge while driving. If you notice it getting too high, pull over and let it cool down before continuing.
