Just won`t start, ran good day before the problem

I'm sorry, there's simply no way to know what's going on here without hands on inspection. You mentioned programmed -- but from here, I'd say that diagnostic testing including proper programming inspection is needed. The concern here is that BMW's often require programming and certain protocols to do most anything. So, I'd suggest the assistance of a BMW tech near you.
