Bmw 2006 530xi please help!!!

[Edwards095]

I have a BMW 2006 530xi (n52 engine). The car cranks heavy like it wants to start but does not start. I am getting fuel, spark & air. I changed the throttle body, cams and crankshaft sensors. Any sort of advice would be greatly appreciated!!!
Codes received:
2A3F

Recently, our 06 530xi started having some trouble starting. It began as slowed turning over, and failure to start on first try. Eventually the starter failed altogether, and didn't turn the engine over at all. Replacement fixed the problem.

The codes seem to point to valvetronic motor and/or throttle potentiometer. Possible wire issue? We have rodent problems here to watch out for. I live out in the country, ask me how I know!! I would start by chasing the wire harness or checking for correct input values to the valvetronic first.
This is on a E90 but might be relevant. https://www.youtube.com/watch?v=j-YfCmzkdKY
