Sounds like the intake cam sensor for sure... the DME uses it's signal for the cam timing/ignition timing etc. so if it doesn't see the signal it kinda makes up default signals from the crank sensor and defaults the VANOS system to not advance the cam timing so it will be slooow... It kinda does the same thing if it loses crank sensor signal by defaulting off the cam sensors, but the cam sensors fail 20 times more often than the crank sensor. I'm actually surprised it didn't throw a code with the long crank/slow drive really.

If you pull the cam sensor out and look at it the old style sensor that has the failure problem is stepped down in diameter just after the o-ring while the new updated BMW cam sensors are thick all the way through.
