I just finished swapping and cleaning my solenoids out today and thanks to this thread I fixed my check engine light! My error codes were as follows:
2A98: NOT present crankshaft-inlet camshaft, reference
2A82: NOT present VANOS intake (Sticky/jammed vanos code)
The car is now running like it should and I am back to being a happy camper!! Originally it wasn't pulling as hard and I was getting inconsistent idling.
See my original thread in the N52 engine section:
