Check my oil analysis - knocking 330D

Can anyone provide any further insight or opinion of my oil analysis report, please?

140000mi M57 330D. Engine has started knocking audibly over the last 1000mi or so, which I'm about to start trying to chase down. No errors, no symptoms besides the noise. Most audible around 1200rpm. It noise is directly with engine RPM - not half speed like timing chain noise, etc.

I haven't done any diagnostic work yet. First up is removing belts to rule out ancilaries and the harmonic damper. I'll also make sure the injectors are all tight. I need some clear weather before I can get into it though!

Thanks
