The fourth-generation Mercedes C-Class, model W205, was produced from 2014 to 2023 and brought S-Class-inspired styling and a wide engine range, including plug-in hybrids, to the compact-executive segment. Its ASSYST PLUS service system and extensive electronics mean the Mercedes C-Class Mk4 W205 (2014-2023) needs values reset after maintenance. The headline task is the oil/ASSYST service reset, done through the instrument cluster to clear the maintenance light, but owners also reset the TPMS after tyre work, carry out a brake pad wear reset when fitting new pads, and register a replacement battery so the intelligent charging system responds correctly. A steering angle reset is standard after alignment. Pick the W205 service reset procedure that matches your completed repair from the list below.
