Minor design flaw, but makes some noise as the lifters wear.
Than stay away from thin and lighweight oils ( 0w-xy or sae20/30...)
Try to get some EU vw 505.01 (full saps) or vw 507 (low saps) oil for vw PD engines...it has additive that makes oil more stay put.....otherwise you ruin cam ( PD injectors are hard on cam...lot of preasure there at cold starts-due to no oil there at cold start)
