How to fix the low coolant level warning in Audi A2 2001?

I recently bought a secondhand Audi A2 2001 and have started getting the low coolant level warning on my dashboard. I checked the coolant level and it seemed fine, so I'm not sure what the issue could be. Can anyone help me fix this issue?

The low coolant level warning is a common issue in Audi A2 cars and can be easily fixed. First, check if the warning is triggered due to a faulty sensor or an actual low coolant level. If it's the sensor, simply replace it. If it's the coolant level, check for any leaks or cracks in the coolant tank and get it fixed.
