I'm sure they have some input but I think the extent of that is aesthetics (size) but just reading Pierburg's webpage seems like they already have teh technology and just scales it to what the manufacturer (BMW) wants. I really don't think that BMW designs/engineers the water pumps just like they don't design/engineers turbo's - they get a manufacturer for it buys it from them.
