Replaced a broken tail light on my 2019 XC60 T5 Momentum last weekend.
Couldn't find much in the way of tail light specific instructions for 2019 XC60's on youtube or elsewhere. The Volvo website does have some very good instructions for fitting Volvo accessories (like trailer hitches, pilot assist, etc), which got me most of the way.
It pretty much took me the equivalent of a whole afternoon to remove and replace the tail light. After having done it once, it would probably only take about an hour or maybe 90 minutes now that I know what to do.
Basically the entire adjacent interior wall trim and the bumper need to be removed before the tail light can be removed. This sounds pretty daunting, but actually isn't too bad if you have the right tools.
In case it is of help to anyone else, I have put together a set of instructions (including a couple of tips and traps) and attached them to this post.
