i googled that code and got directed to a german forum talking about ZF AT failure. seems that code relates to the mechatronic , probably NR.2 here since if thats broken it cannot build pressure.
Especially if this code appears:
0x4F81 Übersetzungsueberwachung Kupplung A

but that could also be caused by low oil , bad oil etc ....

I have suspicion that one of the lines connected to transmission oilcooler is damaged or jumped off , there is a slight oil spill on ground from transmission. Havent been under to check and to make the confusion ever worse , I have a leak steering rack so good luck to me under there...

Anyway , I dont bother more for now , getting the car on a truck and have it shipped to garage for repairs.

Thanks for all input so far

Update:

Picked apart and found that the radiator fan assembly was not properly installed and this allowed for lines connected to heat exchanger to touch rotating wheel from engine.

Now I am going to get the line replaced and need some pointers there if any have been changing these before. Look kind of crowded so Im curious to how much fuzz it will be....
