E60 M5 knocking issues and power loss

Hi all, I was recently plodding along the motorway at around 60mph when the my 2005 E60 M5 went into limp mode, I pulled over immediately and shut the car off as there was a knocking noise coming from the engine, the car has was put on diagnostics at the side of the road and was showing codes for misfires in pot 2 & 4, at present the car starts and does move very very slowly however the knocking noise is very prominent, anybody experienced this before I am thinking possibly VANOS failings?? Any feedback would be great.

I've been around very prominent knocking noise before, before the rod cut the block in half. Failed rod bearings characteristically knock.
