The PS pump on our 2010 S80 V8 was changed by the local stealer a couple of years ago.
You will also need to change over the power steering pump fluid reservoir, as it has a built-in, non-removable filter within it. But the idiot local stealer didn't change ours, and so it was still noisy AF when the car came home after 7 days and after a 6-week wait to get a booking. We then took the car to professionals to sort it and it will never go to the stealers again.
This might save you a few bux if you want to DIY.

I looked up the part number you supplied - Skandix has no record of it, nor does Volvo Parts Webstore. In fact Skandix doesn't list any S80 V8 PS pump, which is very weird. And, yes; Volvo Parts Webstore also lists 36000267 as the V8 PS pump..... it is the successor of p/n 36002681.
