Why is my Audi A4 overheating and how can I fix it?

I've noticed that my Audi A4 has been getting hotter than usual while driving. What could be causing this and what steps can I take to resolve the issue?

The most common cause of overheating in an Audi A4 is a malfunctioning coolant system. Check your coolant levels and ensure there are no leaks or clogs. Also, consider changing your thermostat or water pump if needed.

Another potential cause of overheating in an Audi A4 is a faulty radiator. If your radiator is old, corroded, or damaged, it may not be able to effectively cool your engine. Consider getting it checked and possibly replaced.
