könnte sein, dass die abläufe im lüftungsbereich vorn dicht sind. besonders wenn der wagen unter bäumen parkt.

are you using AC at that moment?
if yes, then it's the drain hose from the AC needs cleaning from under the car, to be able to drain th water from AC.

My car, produces a lot of water there, many people told me that i am leaking something below car.

Anyway, on passenger side, just above steerig rack rubber boot you will see a black rubber hose.

Just clean it.
