2011 BMW x5 xdrive50i won't run.

[Ryanx5]

Hello, I bought the car last year. I love the car but have had some issues. I am tackling them my self. I have done all the plugs and coils. I am also doing the injectors as the fail.

I did cylinder 7 today and now I have a new list of codes I can't figure out. I am no wear near a dealer either.

I the car starts and then dies.

I have double checked all the connections. Checked all the fuses too.

I must be missing something.

2E7C BSD bus com fault
2AA2 intake cam sensor
2AA3 exhaust cam sensor
2A97 crank sensor
5115 engine speed

I know I am new here. Any help would be appreciated.
Thanks,
Ryan

I would check your wiring harness, specifically the harness that houses the injector and coil wiring that runs on each cylinder bank. The bolts that attach this to the engine are grounding points, if you don't tighten one or leave them out, you will kill the ground point for multiple sensors. Double check all your bolts on this harness and also the ground wires to the engine (Main is located down by the steering rack and front diff). Keep us posted what you find.
