How to troubleshoot engine overheating in an Audi A4?

I have recently noticed that my Audi A4's engine is frequently overheating. What could be causing this issue and how can I resolve it?

First, check the coolant level and make sure it is at the appropriate level. If it is low, top it off with the recommended coolant. Also, check for any visible leaks in the cooling system and have them repaired if necessary.

Another common cause of engine overheating is a malfunctioning radiator. Make sure the radiator is not clogged or damaged and have it replaced if needed.
