Aux Rattle?

[kezza87]

Hi, Ive just bought a mk1 Berlingo 600d 1.9d.
Ive been driving for a few weeks and all of a sudden it has started rattling under the bonnet, it sounded like a metallic vibration at first but under closer inspection it is coming from the aux belt area but i cant pin point it exactly but it sounds as though its the PAS pump or something?

The rattle also get louder if im turning left.

any help would be really appreciated.

Thanks

Just a quick update, I figured out is was one of the tension pulleys for the serpentine belt. managed to replace it nice and easy.
