IIRC someone came on here to inform us that BMW have stopped fitting the new type filterless unit and started to fit the filtered type again, as there were issues.
I put a new one on mine and chose the filtered type. I change the filter and gaskets (£10) at each service (15k miles) for piece of mind.
