BMW 325I COOLANT PROBLEM

2001 BMW 325i • 11,000 miles

My car keeps leaking anti freeze. I had a diagnostic test ran and no leaks could be found, but I notice when I don't drive with the heat or ac on it doesn't leak out at all. And when it leaks it leaks out fast meaning I can go not even a whole day driving without it leaking out. What should I do?

I would be suspect of the heater valve. A pressure test of the cooling system, if correctly performed, should indicate where the coolant is being lost.
