MY 2019 Maintenance Booklet
For example, here is the Maintenance info for MY 2017 vehicles (includes not just C-Class though).
I did find one on a Canadian website but it does not go into too much detail on the specifics. It also appears to be from one specific Candian MB dealership. Nothing on the German websites that I could find either.
Just not sure why Mercedes makes this information so hard to find.
