Sounds like your not having any problems other than a knocking sound. This could be coming from your Enviromental Air System. (Heater & AC). MB's have a tendancy to create a knock when they are too hot or too cold and it sounds like its coming from the engine but actually its coming from under your dash near the Floor board.
