sounds like secondary air injection pump, you can unplug it, its not really needed.

either unplug the 50amp fuse that supplies it, or unplug it from the engine bay:

no that did not work as you look at the engine from the front it is coming from the left hand side of the engine

It could be the alternator or the aux belt tensioner. Remove the belt and run the engine briefly to see if the noise goes.

spray the Aux belt with a small amount of WD40 to rule out that as the noise, then listen carefully for any unit making a noise (aircon pump / alternator / tensioner)
