How can I troubleshoot my Audi's malfunctioning cooling system?

I am experiencing issues with my Audi's cooling system, and I'm unsure of how to address the problem. The temperature gauge is showing an abnormal reading and I can hear strange sounds coming from the engine. What steps can I take to troubleshoot this issue?

First, check the coolant level in your Audi. If it's low, top it off and monitor the temperature gauge to see if the issue persists. If the coolant level is fine, you may have a faulty temperature sensor or a malfunctioning thermostat. It's best to take your car to a certified Audi mechanic for further diagnosis and repairs.
