The second-generation Mercedes CLA Mk2 (C118) (2019–Present) is the swoopy four-door coupe and Shooting Brake estate built on Mercedes’ MFA2 platform with the MBUX infotainment suite. Its electronics depth means several systems expect resetting after maintenance. The oil service reset via the Assyst Plus service system is the main one, clearing the wrench through the instrument display once fresh oil is in. A TPMS reset relearns tyre pressures after a rotation, the brake pad wear warning needs clearing when new pads and sensors go on, and steering angle calibration follows alignment work. A replacement 12V battery should be registered so the energy management adapts. Pick your CLA’s service reset from the procedures listed directly below.
