What are the common issues with the Audi A7 cooling system?

I have noticed that my Audi A7's temperature gauge is fluctuating often. What could be the cause of this and how can I fix it?

This could be due to a faulty thermostat or a leak in the cooling system. It's important to get this checked by a certified mechanic before it becomes a bigger issue.

Make sure to regularly check your coolant levels and have the system flushed every 50,000 miles. This can prevent any potential issues.

If the temperature gauge is consistently fluctuating, it could be a sign of a failing water pump. It's best to have it replaced before it completely fails and causes further damage.
