The fourth-generation Mercedes A-Class, model W177, has been built since 2018 and introduced the MBUX infotainment system along with a sleeker, more aerodynamic hatchback body. With its ASSYST PLUS service tracking and dense electronics, the Mercedes A-Class Mk4 W177 (2018-Present) needs values reset after maintenance. The headline task is the oil/ASSYST service reset, performed through the cluster to clear the maintenance light, while a TPMS reset re-baselines the tyre monitor after a pressure change. Owners renewing brake pads should carry out a brake pad wear reset, and a replacement battery should be registered so the intelligent charging system responds correctly. A steering angle reset follows alignment work. Find the W177 reset that matches your repair in the list below and work through it to clear the dash.
