I'm assuming this is the cranckcase breather housing? If so, how do I get in there? Do I remove the hoses and the four allen screws? This isn't like any of the ones I've seen to YouTube! 😀

What is the year of your D4?
D4 from 2021 and newer do not have a crankcase filter to replace. Older ones do.

Ha! So that's why I can't find it! It's a 2025. BTW, does anyone need a brand new crankcase breather filter for a <2021 Volvo d4? HeHe.
