How To Reset Oil Service Light On Mercedes-Benz CLA-250 (2014-2018)

What’s up, Mercy fam! Today for another post on how to reset the oil service light on the Mercedes-Benz CLA-250. I’ve never owned a Mercedes-Benz before, so I panicked kind oh my god, what’s the service B?! I don’t know if it was just regular maintenance, so I did a little research to see what exactly service B was.

As I was looking, I saw that it was just a regular oil change, air filter, replacement brake fluid change and topping off fluids, and just a multi-point inspection. So I decided to do my own service B and reset the service light for myself.
