You will need a T-25 Torx bit to do this job. Make sure you have that first.
Here's a pic of my old armrest looking bad where the faux leather is peeling away:

Open the lid to the console and remove the four T-25 Torx screws (two at the top and two and the bottom):

Now lift the cover off of the console lid. This is what it looks like with no cover. That gismo in the middle is what keeps the lid open when you let go.

Now open the lid all the way and make sure the hold-open gismo is in the notch as shown here at the tip of my finger (if you don't, the gismo won't work right):

While holding the lid in the vertical position, slide the cover on and install the four Torx screws. You're done. Here's what mine looked like (a marked improvement!):

I will load this into the S80 Repair Database. I don't know if it applies to other models.
