I'll try to attach the N62 Pdf.
Basically the the Vanos solenoids open up in a chamber in the head, one for exhaust, and one for intake, based on when the DME (engine computer) need to the timing of the cams to advance or retard for more power and smoother operation through the whole power band (in a nutshell). lol
Now if the seals are bad or leaking the full oil pressure will not make it up to the vanos cam units to advance or retard the timing, resulting in power loss, and other things.
Here's a good PDF that explains the operations :
