Here's a picture if the timing chain arrangement, only one tensioner but a few rubbing blades. The noise is normally the chain slapping against the rubbing blade as its not tight enough. I'm not sure about this one but you can manually click the tensioner in on some models. I'll try and find out if you can do this on the CRD
I removed my oil fill cap and shown a flashlight down inside. I could see the timing chain tensioner pushing against the timing chain tensioner rail. It just looks like a bolt pressing against the plastic rail. You should be able to see the same thing.
Now, you can idle the engine with the oil fill cap off, but oil splashes out and makes a mess. Regardless, perhaps you could run it for a few seconds and see if the timing chain looks loose. Just keep some rags laid around the oil fill hole when the cap is off so that you can clean up the mess.

And wear safety googles Have you pulled your turbo inlet hose to make sure no turbo vanes broke loose and are rattling around? They would likely get caught in the Intercooler if that was the case so probably not relevant. Could there be any loose bolts rattling on the backside of your engine? Trying to eliminate the easy stuff before you tear down...

Thanks for the suggestions folks.
I had read that TSB before but because the noise appears to be coming from the timing chain area and I don't hear anything coming from the base of the engine, I discounted it.
I have heard main bearings knocking before and it never sounded like that.
Worth a rethink...thanks 10Xk
Well, I'm heading out of the country for a couple of weeks and the problem will have to wait till I get back. I had a look at the serpentine belt removal and I'm not sure I'm feeling confident enough to do that! I can hardly even see the darn thing let alone remove it.
So, hopfully I can find a diesel mechanic to do the work, preferably not the dealership.
Thanks for all your help..I will keep you posted
