    My advice/experience was directed to NTXC who is not the original poster so yes, my post was off-topic.

    I'd still like to change the rear diff fluid in my recently acquired 2007XC. Seems like I'm seeing 2 options: replace the exact same amount of fluid that was removed OR fill until fluid drips out and then remove 100 ml. Guess I'll boot up VIDA and see what it recommends for the procedure.

    When i first got my 04 in 2012 i went through all the lubricants and changed them all, the Haldex included, without the benefit of the forum or the Vida i just drained and refilled the diffs using the "fill to plug level", never gave it a thought, now it seems I did it incorrectly, though i have yet to see any problem from my overfill, no pushing out the vent, no leaks, so maybe next time i change them i will correct my overfill though it had no detrimental effects at all.

    The procedure to remove some oil wasn't included when the model first came out, it was
    included a few years later after some cars showed problems. It's not only for the rear
    differential, for the angle gear the procedure says to remove 160mL, 100mL for the AOC.

    The dealer told me that the correct level is when oil drops out of the fill hole.

    Did you fill the differential until the oil reached the bottom of the fill hole?
    If so, then there is too much oil in it. 100mL should be removed.
    Thanks. What will happen if its filled to the bottom of fill hole? The dealer said thats what they do.

    I did that on my 04 years ago, nothing happened. no leaks, never a issue with it in my case.

    Probably nothing nothing will happen,but in the past, some cars had problems when filled completely,
    that's why Volvo changed the procedure to take out a certain amount.
    I have Vida instructions (in Dutch) from Vida 2010 that calls for removing some oil on a MY2004 and
    probably on all MYs with the same equipment.
    Possible problems may only occur when the car is heavily stressed.
    When I changed the oil I followed the procedure to remove 100mL.
