It's likely the Eccentric Shaft Position Sensor.

Change the sensor

hey guys i'm looking at some diagram and cant locate the sensor i have a xdrive28i 2.0L don't know if this makes a difference ....

can someone send me a diagram and a part number with it all i'm seeing is the sensors for different bmw engines...

Yes a failed sensor will create a no-start situation.

I'd read this.

That sensor is actually built in to the servomotor and will require replacement of the complete servomotor which requires removal of the valve cover. Also, there is a chance the defect is within the DME. In that case you would have to replace the DME.
