Main dealer servicing presumably means CBS - in which case oil probably not changed as frequently as it should...

If you've got a service plan for instance they won't touch it until the light or time duration comes up for these engines its way way too long plus when looked at the breather valve was saturated air filter was IMO dirtier than I'd of expected. Engine of course is scrap. Replacement engine going in as its the only option.

And this is why I change the oil and filter between scheduled services and also change the air filter, micro filter, oil separator and clean the EGR as part of a regular 6 month or 8-10k mile maintenance program.

What sort of knocking sound was it? A metallic knock or a low tone thumping type sound? I have a low thump sound but am assuming its my DMF which i know is knackered anyway and getting changed next week....
