I had this happen to me (m103, but it's the same thing on the m104). It's your heater-to engine hose. If it was the ATF hose, the fluid would be red, and you wouldn't lose coolant. It's a straightforward, easy and inexpensive fix. The hose comes from the firewall on the driver's side, goes through a grommet in the partition between where the fusebox is and the engine compartment, and down towards the cylinder head. Feel with your fingers and a flashlight for wetness around the hose & the split. You can find the hose online, or you can go to your local MB dealer and they should have it for you next day, and for not much more expensive.
