What are the common coolant leak symptoms in an Audi A1?

I've noticed some fluid under my Audi A1 and I suspect it could be a coolant leak. What are the common signs of a coolant leak in an Audi A1 and what should I do about it?

The most common symptom of a coolant leak in an Audi A1 is a low coolant level. You can check this by looking at the coolant reservoir. If it's below the minimum level mark, you likely have a leak.

Another common sign of a coolant leak is white smoke coming from the exhaust pipe. This could indicate that coolant is leaking into the combustion chamber and being burned along with fuel.
