Dropped my 2004 4.4 off for Inspection II yesterday. During the oil change the tech found some small metal shavings and they determined were caused by a degrading oil pump that is about to fail and needs to be replaced. The repair job is $2500, but my great service advisor got BMWNA to pay for it. My question: is an oil pump failure at 60k miles[which seems very early for this type of problem] cause for greater concern regarding my X?
