Would be good to know what the problem was here.

 

I took it to a local BMW specialist, I told him everything I had done and the results of any tests I had carried out. He agreed that it was a fuel problem, he loosened the high pressure fuel line and cranked the engine over a few times until there was fuel coming out, he then tightened the fuel line back up and the car started and has ran fine ever since 👍🏼 He said it was air in the fuel line and for some reason it wasn't self bleeding like it should do, I'm just glad it's up and running again as it's an awesome car and I really enjoy every minute of driving it 😉
