The videos about removing the valve covers on the N62 do mention the valvetronic motor can "shoot out" I guess it just depends where they after when it shuts off.

You had a very specific vanos error bank 2; swap the solinoids all four from Bank 2&1 and see if the problrm migrates. Of course after to do the leak down and compression test (shoud not be a problem).

Did you determine the source of the plastic bits and the chunk of steel?
