Is there any technical read up on the S65 low pressure VANOS system especially the stepper motor/actuator that is replacing the high pressure VANOS (hydraulic piston, piston bearing, helical gear) in the S85 ?

Everything I found online is for high pressurized oil VANOS which is irrelevant.
More knowledge would help categorize noise sources issues.
