190d clutch pedal swings freely

[penguinsscareme]

So this morning I went out to start the 190d, and the clutch pedal went right to the floor with no resistance and came right back up when I let off it, hanging almost limp on its bracket. I've never had any problems with the clutch up to this point. It was two degrees below zero (Fahrenheit) when this happened. Does this portend a new master and slave cylinder in my imminent future?
