I know this is an old post but recently I had the same issue. My local MB garage said the o-rings for the transmission tubes were bad. Well, lo and behold, I drove the car into Chicago and when I came out to the parking garage, I had a large puddle of coolant. The radiator had a crack between the inlet and outlet hoses. It was $2300 to repair at MB of Naperville.
