i also have a coolant leak on my 190e2.6, and it happens after I turn off the engine. I have traced it to the heater valve - initially I thought that it was just a loose hose on the valve, and after tightening it, I still got the leak. After inspecting it a second time, I found out that the valve itself was leaking.

i believe it happens after I turn off the engine because the engine is hot and continues to transfer heat to the coolant after you turn it off, and because the coolant is no longer circulating, pressure increases and makes the heater valve leak.
