I had similar problems and although I thought the battery was ok and it turned over fine, it wasn't BHM listened to it via my phone and said try a jump start.
That worked and a new battery was the answer.

Thank you Tim! But a new battery was the thing I had changed. Now the new coil (cylinder 2 I think) and a new camsensor is fitted.
Let crank him for about 20/25 seconds… he doesn’t wake up.
The next days a little more work at him.
