Buzzing noise on Vr6 ????

Well if those wires are to the water pump then it could be coming from there because if i un screw it whilst its making the noise the noise goes

That wire connector feeds loads of things, well i suppose that much is obvious 
The water pump is supposed to buzz when you turn the ignition on, it then goes off when you start the car.
I would look closer at it.

So all Vr6'S make the buzzing noise when the ignition is on ?

If you look like bolland said to the left of the connector there is a water pump, place your finger on it and see if you can feel it when you hear the buzzing.

Also I wouldnt keep disconnecting that connector with the ignition on as you may knacker the ECU with a power spike.

Your car hasnt got the coil which is what overseer suggests  as as you can clearly from your pic the HT leads coming from the coil pack.
