What are the most common causes of engine overheating in an Audi A6?

I have a 2015 Audi A6 and just recently had my engine overheat. I want to know what causes this issue and how I can prevent it from happening again.

One of the most common causes of engine overheating in an Audi A6 is a faulty thermostat. It can cause the engine to run at a higher temperature than it should, leading to overheating. To prevent this, have your thermostat checked regularly and replace it if necessary.

Low coolant levels can also result in engine overheating in an Audi A6. Check your coolant levels regularly and top up if needed. If your coolant levels continue to drop, it may be a sign of a leak that needs to be addressed.
