My 2017 XC60 is due for 40K maintenance: and I wanted to see if I can change both engine and cabin air filters myself. I've done it before on 740 and on S70 (took me 10 min max) that I used to own, but not on this one. Is it hard? Are there tutorials or videos that describe it well? How much time should I allocate for this, as I am doing it for the first time?
