Trying to identify some of the noises coming from my new Mini S. I know the ticking is from the injectors, but I have another noise that sounds like it might be the Vacuum pump. Where is the vacuum pump located on this engine?

 

It simplest terms possible...its the round silver thing on the right side of the cylinder head, towards the front of the car. The other, non-round silver thing on the right hand side, towards the back is the high pressure fuel pump.

Heres a diagram for you:

 

Thanks
