Today I've been looking at it more closely. It is definitely dripping down from the area of the servo pump. Where exactly a leak is, I could not see.
There are pipes in the area of the servo pump that lead to coolant (ev. Gear cooling, etc.)
The joke is that since I got the car, I've noticed it's dripping out of the berry. So far it has always looked like oil - especially when parking, which would be somehow logical because of the higher load on the power steering.
But the fact that green liquid is finally leaking out is another new thing. Nevertheless, neither in the hydraulic fluid tank nor in the coolant tank can be noticed a loss. Somewhere this stuff has to come here.
