Strange codes - N52

My 09 128i is about to hit 200k miles and it's started displaying strange codes.

2AA0: Camshaft sensor, inlet, signal
2A82: VANOS intake
2A9A: Crankshaft - inlet camshaft, synchronization
2A9E: Camshaft sensor, inlet, synchronization

Has anyone else run into this combination. Im not sure if it's electrical related or a bad sensor somewhere. I have no idea how to diagnose this and the only component on this list that hasn't been replaced this year is the crankshaft sensor but I don't want to throw money at it until I know it's the problem.

Search thru here for ground cables, especially one between starter and body ground.

Did you get it fixed?

I just replaced the valve cover, oil filter housing gasket, water pump and thermostat, and the valvetronic motor/eccentric shaft actuator. Now all of a sudden, rough idle, seems like the vanos/valvetronic isn't working anymore when driving due to throttle responsiveness, or rather lack of. Throwing code 2A82 vanos intake, as well as 2A99 Crankshaft exhaust camshaft. if you got any leads on yours, i'd love to hear! Thanks.
