Gotcha. I, too, out of curiosity tried to follow some hoses... cables... and lines then stopping when I thought about how just 1 brittle hose could put a dent in the day.

Breather hose makes sense. Maybe an expert can chime in and explain how PS fluid contracts and/or expands under temperature... and it needs somewhere to vent.

Or, did I just do that?

In any event... if Porsche designed that line to just dump the fluid wherever... then my wherever I'm going to give some consideration.
