The vanos rattle is caused by wear in the variable valve timing helical (slanted) gears. The helical gear wear allows the camshaft to have lash movements that engage the splined shaft axially. At certain RPMs these movements resonate and engage axial play (free space) and cause associated components to hit and rattle .
