What to do when my Audi A3's engine is overheating?

Recently, my Audi A3's engine has been overheating frequently. I've checked the coolant levels and they seem to be fine. What could be the issue and how can I prevent it from happening again?

John, it sounds like the issue may lie with your radiator. Over time, the radiator can become clogged with dirt and debris which can prevent proper cooling of the engine. I recommend taking your car to a certified mechanic to have them inspect and potentially replace your radiator.
