Re: loud knocking
Difficult to tell without hearing it, could be an injector, does it sound like a diesel knock or a mechanical noise?

Re: loud knocking
Crankshaft pulley would be my thought too - have a look and see if looks rusty on and around the face.

Re: loud knocking
As above, I think you should start in the auxiliary belt area ?? The metal "duel mass" crank pulleys on HDi`s can fall apart and make all sorts of noises. Also if the auxiliary belt tensioner fails it will rattle like bag of nails.At idle you can see it jumping up and down on the belt.
