Resetting service/Oil interval on a 2019 c class 300d

[Mickyh7]

As per the title, I'm finding mixed information on this. Is it actually possible to do without an OBD2 scanner.
C300d, W205.
I don't mind buying one, but not if I don't have to.
My car is out of warranty, so I'll be doing my own services and have a self warranty stash that I've saved over the years, by never paying for a second warranty, and never having a major problem!
I also have no trust in dealers or their apprentices!
I am very happy to do this and not nervous at all.
Does anyone actually know, honestly i.e. done it? Seen it done?
Thanks in anticipation.

Use the steering wheel controls and it can be done, you'll need to search for which buttons to press.

Have you checked in the owner's handbook, maybe listed there?
