Experience with leaky steering gears at the Panamera turbo 970

Hello I have a Panamera 970 turbo from 2009. before my drive in I have seen on the ground oil stains and first of all not noticed. Only when I had the same stains at the REWE it was clear to me from my car. I assume that it is power steering oil, since the considerable stains are only at the places where I did not just drive out. And at the place where I parked is only 1-2 drops. Does any of you experience Servo oil loss ?? you mean the steering ger iebe should be replaced, or is it rather a leaking hose from the servo pump to the steering gear that is leaking at the pressed ends.
