The vacuum pump on my wife's 08 petrol i6 3.2l has been leaking oil for a while. It's been pulling vacuum just fine but leaking oil like a sive. Been putting it off but finally got around to tackling this today. Start by disconnecting the battery negative cable and remove the decorative cover to expose the engine. Then disconnect the MAF sensor plug on the side of the air box. There is also a push in retainer clip that hold the MAF wires to the air box.

Next use channel locks or vice grips to loosen the air inlet tube and carefully pull it off the air box.

Now remove the push in retaining clip that attaches the positive battery cable to the side of the air box. Then pull up firmly on the air box to remove it. It is not bolted in. It is held in place by rubber push in things.

Make sure you didn't lose any of your rubber push in thingys like I did. If you did find them and simply push them back in to reinstall them.

This is the faulty vacuum pump found on many Land Rover-Volvo-Ford products. Thank goodness it is because Land Rover procedure is an expensive swap for a new one. Volvo on the other hand provides a very simple and INEXPENSIVE rebuild kit. Shame on you Land Rover. Note that the two wire clips described above are visible in this pic

This little guy is held in place with two 10mm bolts. But before we can get to one of them we have to remove one of the ac compressor brackets. It also is retained by two 10mm bolts and a 13mm bolt. Here I've losened two of three with the last bolt visible at the end of the bracket still tight.

To make more room to remove the ac bracket and to remove the vacuum line I removed the push in clips that hold the wiring harness that runs above the vacuum pump. You can also clearly see the vacuum line that will be removed in the next step.

Remove the vacuum line by pinching the sides of the oblong retaining clip by hand to make it a circle and gently pull back to remove it from the pump.

Finally, remove the two 10mm bolts and pull out the pump. Nothing will go flying. It's self contained. Note this picture of the retaining bolt is pre removing of the ac bracket. See why it had to go??

And here's what it looks like engine side with the pump removed. Note the slot inside the hole that will have to be lined up later during reassembly. I have no idea why the forum inverts my pics..

Here it is out of the truck front and back..

Now to begin the rebuild make sure your kit is complete. It is Volvo part number 31401556 and it contains 5 new self starting screws, 2 ring style gaskets, and a new vacuum fitting.

Remove the 5 torx screws using a #25 torx bit and inside will look like this...the Black piece slips right out for cleaning the inside of the pump but is 3 pieces so don't lose them!

Remove the old vacuum fitting by pressing the plastic tabs with a small flathead screwdriver while pulling outward.

Now remove the two old gaskets and clean up all your gasket mating
surfaces. I used a brass wire brush taking care to not allow debris to enter the body or orifaces of the pump. Replace the vacuum plug by simply popping in the new one. To get mine to seat properly I had to give it a single light rap with a rubber mallet.
