in some correspondence about radiator flushes with mike miller of roundel,he said that bmw had made it hard to do a full coolant flush on bmw's built after 2006 without extensive,and therefore expensive,disassembly,and that because of that the best you can do is drain and fill the radiator,which it looks like you have done.
