Mein Auto: 2002 bmw 525i
For the guys following this post.
after more and more research I decided to disconnect the VANOS solenoids as other have in the past to disable the valvetronic system and set the VANOS cams to a null position.
well this thing is smooth as glass, started great no hicups, idles smooth and runs great.

looks like since the problems were only bank 2 side, I can only assume this is indication eccentric cam or lever wear, or VANOS cam gear issue.

I believe I will just stare at the check engine light and drive until its engine change time.

thanks for all who posted, I was able to rebuild the drivers seat, troubleshoot and fix the idrive controller and navigation issues, repair the transmission valve body solenoid all while trying to figure this engine out. thanks everyone!
