Check your coils. Take off the valve-cover plastic covers that say BMW on them. Remove those 10mm nuts holding on your coils. Start the car and pull the coils out slowly. You should hear sparks as you pull them out, if you don't than you have dead coils. Cylinder 4 is the cylinder closest to the fire-wall on passenger side. And Cylinder-8 is again closest to fire-wall on driver-side. Are your valve-covers leaking? Cam position sensors cause misfiring too
