Hey Dado, mine had a leak but it stopped as misteriously as it started. My E38 740 buddy David fixed his auxiliary water pump and if has been good for a coupke of years now. His instructions were simple, take apart the auxiliary water pump and reseal by applying RTV to the mating surfaces, put part back togeather but do not tighten the bolts all the way, wait as per RTV instructions for the sealant to setup, then tighten to spec.
Try it what do you have to loose.
