I had the same issue on my E430. Assumed it was crank sensor -- but code reader said cam sensor, and was correct.
On your car it is the "Top Dead Center" sensor and connects to the ECU. If it is failing then the " car can have a multitude of problems, from rough running all the way to not starting at all." Sounds like what you are experiencing. Here is the local opinion:
