How do I troubleshoot a coolant leak in my Audi A5?

I noticed a puddle of coolant under my car after parking it for a few hours. What could be causing this issue and how can I fix it?

The most common cause of a coolant leak in an Audi A5 is a faulty water pump. It is recommended to have this issue checked and repaired by a certified mechanic.

Another possible cause of a coolant leak could be a damaged radiator. It's important to have this inspected and replaced if necessary to avoid further damage to the engine.

In some cases, an old or worn out coolant hose can also be the culprit of a coolant leak. It's important to regularly check and replace these hoses as part of your car's maintenance.
