Yes, and exactly how do you 'check' the "15mm below the lower lip" while
you are filling up that tranny?  I'd say trust the factory before changing
to what Bentley says, especially given the awkwardness of trying to fill
your gearbox and check for "Level plug minus 15mm" while you have gear oil
dripping from a hose and you're crawling around under the van..maybe with an
ink line on your little finger?
