Hey folks. So I did a post little while ago with no response. Hopefully this one will generate some helpful info

I'm fighting a drive train malfunction. 2011 x6m E71 163xxxKms
I have replaced timing chains ,intake and exhaust cams(new bolts)

Timing is good. I'm getting a cam sensor code. Reduced power. Code reads 2AA6 with ecu Variant MSD85,MSS70,MSD85Y.
I have swapped sensors around with no change.
Where can I look next??

Please help.

other codes not sure if related 2E7C (BSD Data Bus Communication's fault)
2E8B (BSD Message IBS missing)

Thank you
