8,4 Liters, first i used Valvoline, beacuse my part shop said it was right type, Launch diagnostic tool was used and not Ista, when problem occured we changed oil With OEM DCTF 2, and had done adaption with ISTA and no sucsses, also new filter were changed.

2 days ago bmw mechanic updated newest software for transmmision with ISTA also no sucsses, ive heard that it could be possible that first time oil change was done something might went wrong and mechantronic unit locked itself to protecet it self if pressure would rise above 5 bar, beacuse now clutches have only 4 bar of pressure.
