How to fix a coolant leak in an Audi A1?

I noticed a small pool of coolant under my car after leaving it parked for a while. How can I locate and fix the source of the leak in my Audi A1?

You should first check the hoses and connections for any cracks or leaks. If they seem fine, the next step would be to inspect the water pump and thermostat housing for any signs of leakage. If you still can't find the source of the leak, it might be a problem with the radiator or heater core. It's always best to take your car to a mechanic for a proper diagnosis and repair.
