The auto start-stop feature on the 2020 Mercedes is quite annoying. I often experience the engine shutting off when stopping and jerking when starting, making the ride uncomfortable. To permanently disable it, don't think just pressing a button will do—that's only a temporary solution requiring reactivation every startup. A permanent shutdown requires special methods, like accessing the vehicle's hidden menu to adjust settings. You'll need to hold down both steering wheel buttons simultaneously while parked, though exact steps vary by model. Another approach is using an OBD diagnostic tool to connect to the car's computer and reprogram the start-stop function. From my time on owner forums, many drivers share that paying a professional shop to modify the code is safer, though it might cost a few hundred bucks. DIY attempts carry risks—messing up the system isn't worth it, since start-stop is designed for fuel economy and eco-friendliness. But disabling it completely ensures smoother starts, less battery wear, and better long-term driving comfort.
Driving a Mercedes often gives me a headache with its start-stop system. The engine always restarts when starting off, which is quite annoying. I've looked into many resources, and completely disabling this function is no small task because it's designed to activate by default. The simple method is to press the start-stop button on the center console after starting the car to temporarily turn it off, but this has to be repeated every time you drive. To permanently disable it, you need to enter the engineering mode to change the settings, which requires careful operation: for example, turn off the engine, turn the key without starting the car, then press a specific key combination to bring up the hidden menu and set the start-stop option to disabled. However, I don't recommend doing it yourself as it's easy to cause malfunctions; it's more convenient to find a reliable repair shop to reprogram the ECU with tools. The downside is a slight increase in fuel consumption and faster battery aging, but the comfort improvement is noticeable after long-term use. Personally, I think keeping the start-stop on isn't bad—it saves some fuel money—but disabling it is just for peace and quiet.
