Found it after removing the splitter and the grille.Just an ordinary puncture of the gearbox oil cooler

Now I have to try to get it repaired or replaced here in Sweden. P/N is 52-10328-01 from Setrab oilcoolers ( made in Sweden).
Is there somebody here that have instructions available where and how to check and refill the gearbox oil.Also the oil spec is very welcome.
No dealer here within 350 km.
