You probably know this but if you highlight the line that has the part number, right click and select supercession, you can see all the equivalent PN's with the latest at the top. Post a photo of your pump & cable connectors if you can. I'd like to compare to mine. I'm very curious if pumps are interchangeable. I love the X5, it's likely the last non-turbo Bimmer I'll ever have, but I'm also getting tired of changing water pumps.
