How to diagnose and fix coolant leaks in Audi A7?

I've noticed a puddle of green fluid under my Audi A7 and I suspect it might be a coolant leak. How can I accurately diagnose and fix the issue?

First, check the coolant level and make sure it's not too low. Then, inspect for any visible signs of leaks such as wet spots or damp hoses. If you can't find a clear source, it's best to take your car to a mechanic for a pressure test.

If the leak is coming from a hose, you can try to tighten the clamps or replace the hose yourself. Otherwise, it's best to have a professional handle the repair to ensure it is done correctly and no other underlying issues are missed.

Coolant leaks can also be caused by a damaged radiator or water pump. Check for any cracks or corrosion on these components and replace if necessary. It's important to address the issue promptly to avoid overheating and potential engine damage.
