So I used the BG 44k in the car. Nothing has change.
Last weekend I was on the road and the car was ok until it suddendly turns on EML light on, brake light in yellow color and the DSC and limit the car to low speed, it is like a protection mode . I pulled aside turned it off and when I turned it on again it was fine.
Tha car was storage for a long time, the first owner used it very rarely, so I got the car into the bmw shop for a complete general checked, until next week I will have no answer from them.
