How do I troubleshoot a leaking coolant in my Audi A2?

I noticed that there was a puddle of green fluid under my Audi A2 after parking it overnight. How do I determine where the leak is coming from and how can I fix it?

First, check the coolant reservoir and see if it is at the proper level. If it is low or empty, that could be the cause of the leak. You can top it off with water for now, but make sure to get it checked by a mechanic as soon as possible.

If the reservoir is at the proper level, then you will need to inspect the radiator, hoses, and water pump. Look for any cracks, holes, or loose connections that could be causing the leak.

If you can't find the source of the leak, it is best to take your Audi A2 to a trusted mechanic. They have the tools and expertise to diagnose and fix any issues with the coolant system.
