Engine noise - occasional - solved

Towards the end of video. Seems like upper belt pulley area. Car has 170k miles. 2.0hdi

Sounds like a dying bearing someplace,
Best check your cambelt in case one of the pulleys, or water pump is about to destroy the engine.

Ok. I intentionally failed to provide data of last cambelt change. Did it in 2013, 95k miles ago. Just to not skew the perception of noise.
Prepping the car for sale, so a tad unwanted expense.

But if you are lucky, ancillaries, alternator, tensioner pulley, etc.
Some diesels, eg 1.6 hdi have a freewheeling pully on the alternator, can these make noise?

A horrible grinding/ ringing noise I had years ago was a departed clutch disc shock spring that got caught in the bellhousing & was merrily lathing itself against the outside of the flywheel. A Lidl's endoscope might give you some joy.

Got a full service set to be safe.
This one had a free wheeling pulley, replaced with fixed one
Clutch would prolly make a constant or close to constant noise. Have a rather new clutch.

Full service cured it. Water pump belt gear ground into housing..the only thing with physical damage. All belts, pulleys and tensioners seem fine.
