Thanks guys. Yes I have flushed and cycled the engine a few times now. I think I will have to dissemble more hoses to drain it all. Have to say it's a bad design for an engine. BMW must have purposely designed it like this. The hoses around the engine are easy to install, (Quick connect type), but not service of coolant, No, this needs special equipment and procedures. Haha. [emoji3515]
