    Which they wouldn’t warranty.

    So, “the dealer does it” might mean that that procedure is good.

    Or it might mean that procedure is a total cost-cutting, amateur mistake that leaves owners holding the bag.
    The second one, applies more often sadly... Cost cutting,or amateur leaving the owners to pay the price in long term

    Does the differential of these cars have a relief valve?

    All diffs should have one. Ours has a hole near one of bolts, which could be a breather hole. Noticed it recently when was replacing EVAP diagnostic pump, it's on the right side near the center line.

    Taking a look at the pdf I posted in #5, I am not sure there is a relief valve.
    Perhaps item 14, the bleeder nipple (although the name suggests something elso to me)?
    I repeat myself when I say that Volvo must have had a reason to call for the removal of some of the fluid,
    according to a technician I know well this was the result of problems, more specific blown seals.
    The 2010 version of Vida for a MY2004 XC70 calls for removal of 100mL.
    Of course one is free to follow the recommendations of the manufacturer or to choose not to do so.

    Right, #14 and #13 (filter) look like it.

    Seals will leak unless some oil amount is pumped out.
