BMW 325D noise coming from engine

Hello,
I have a 2011 325D with the n57 block with 94,000 miles on it. I've made couple of threads before about the car but there's a noise (which sounds almost identical to a noisy diff) at the front of the engine. This noise becomes apparent when after the engine is warm and louder after a motorway run. A link to a video highlighting this "metallic noise" is provided.
The noise can be heard by listening next to the drivers side wheel. Could anyone shed any light on it?

Could it be any of the belts at the front or a pulley?
Thanks
Reece
