If you loosened the bearings then that's not likely the problem. There is no easy way to test this with the vanos mounted. The bearing fit should have resistance to rotation and you should be able to engage the axial play. The bearing would need to be significantly binding for there to be a problem.

P1520 can occur after a seals install. This is due to the rough new seals. It will go away after ~50 city miles.
Make sure you have an OEM CPS sensor. Use a mirror and flashlight to check for a BMW logo.

Your symptoms seem sever. Make sure all the electrical connectors are installed. There is the intake and exhaust CPS and the vanos intake solenoid.

Did you perform other repairs during this procedure?
