How do I troubleshoot my Audi A7's engine overheating?

I have noticed that my Audi A7's engine has been overheating, especially during long drives. What could be causing this issue and how can I fix it?

A common cause of engine overheating in Audi A7s is a malfunctioning thermostat. It may be opening too late or not at all, causing the engine to overheat. I would recommend getting it checked and replaced if necessary.

Another potential cause could be a leak in the cooling system. This could range from a simple hose leak to a more serious issue with the radiator or water pump. It's important to have this checked and repaired as soon as possible to prevent further damage to the engine.
