Credit to AM and Andrew for nailing this one I think. It definitely sounds like the oil pump.

AM- good question. I'm following your line of thought. Not that I know of, I bought the car in September with 83K miles and no records (ugh). I can check the CarFax history for clues.

I suppose it is possible it sucked in some belt in the past, damaging the oil pump, but escaping engine death. It doesn't have any lifter noise, oil pressure lights or other issues that I can tell.

BMW calls this noise "normal" on the 50i X5's. Yet they replace pumps under warranty in the past. I wonder if this noise is safe to continue driving.
