Peugeot 408 can permanently disable the auto start-stop function. Below are the detailed introductions of the related content: Introduction: The permanent disable button for the auto start-stop function in Peugeot 408 is located to the right of the car's one-button start position. It is an A button surrounded by a rotating arrow. Working Principle: The working principle of the auto start-stop function in Peugeot 408 mainly involves when the vehicle stops moving due to congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically detects: the engine is idling and not in gear; the wheel speed sensor of the anti-lock system shows zero; the electronic battery sensor indicates there is enough energy for the next start. Once these three conditions are met, the engine automatically stops running. When the traffic light turns green, the driver presses the clutch, and the 'start stopper' can be activated immediately, quickly starting the engine. In automatic transmission models, as soon as the brake is released or the steering wheel is turned, the engine automatically ignites again, allowing the driver to press the accelerator and start moving immediately, all while remaining in D gear.
I've been driving the Peugeot 408 for several years, and the auto start-stop function is quite annoying. The slight shudder every time I start moving makes me uncomfortable. Can it be permanently turned off? Actually, every time after starting the car, there's a button on the dashboard that can turn off the start-stop function with a press, but it automatically resets the next time you start the car. To turn it off completely, some car owners go to the 4S shop to modify the software settings with a computer, but doing this during the warranty period might affect the warranty, and improper modifications can also trigger fault codes. I suggest not bothering with permanent deactivation; just get into the habit of pressing the button every time you drive. After all, the start-stop function can save some fuel costs, and long-term use contributes a bit to environmental protection.
As a Peugeot 408 owner, I find the auto start-stop feature particularly annoying in traffic jams, with the engine constantly shutting off and restarting, which feels quite uncomfortable. Many people have asked me how to permanently disable it. I can only say it's technically possible, such as using an OBD tool at a professional repair shop to modify parameters, but this requires technical expertise, and mistakes could potentially damage the system software. When I drive, I usually press the start-stop button near the steering wheel to turn it off. Although it requires operation every time, it's safe and worry-free. The start-stop design aims to save fuel and reduce emissions. Permanently disabling it would lose these benefits and might violate modification regulations, so it's better to adapt to it.
