Firstly, make sure the coolant reservoir and radiator are filled up to the recommended level. Then, inspect the hoses and radiator for any visible leaks. If there are no visible leaks, it could be a problem with the water pump or heater core. I recommend taking it to a mechanic for a proper diagnosis.

In my experience, the most common cause of coolant leaks in Audi A4s is a faulty water pump. If your coolant is leaking from the front of the engine, this is likely the issue. I suggest replacing the water pump and related components, such as the thermostat and belt, to prevent any future leaks.
