Technical Ducato battery light and noise help

[Pjrowe95]

Hi all,

Battery light came on a few days ago, checked the voltage and it’s showing 14 so I’m assuming it’s good, have it booked in next week to be looked at but yesterday it started making this noise whenever you let off the revs, seems to be coming from within the engine does anyway have any idea what this could be? Have attached a video

Van is Ducato 30 SWB multijet 100 2009

Thanks

Can’t be sure but putting the two things together would make me question if the bearings in the alternator have failed.
