How to Permanently Disable the Engine Start-Stop System?
2 Answers
Engine start-stop can be deactivated by pressing the auto start-stop button (usually a circular arrow with the letter A). The vehicle dashboard will display a system shutdown notification. Below is additional information: 1. To reactivate the start-stop function, simply press the button again. This feature is a control program and can be permanently disabled. 2. There are many misconceptions about the auto start-stop feature, such as concerns that frequent starts may cause piston wear, generating metal debris that could damage other engine components, leading to significant engine damage over time. In reality, most engine wear occurs during cold starts. The auto start-stop primarily operates under hot-start conditions where the engine is warm, and engine oil has proper viscosity and adheres to components, resulting in minimal wear.
As a regular driver, I find it quite annoying to manually turn off the start-stop function every time I get in the car, especially when frequently stopping at red lights in the city. To disable it permanently, the most common methods are holding down the vehicle's built-in start-stop button for a few seconds or finding hidden settings. Many cars, such as Japanese or German models, can have their programming modified using an OBD diagnostic tool connected to a computer to permanently deactivate the feature. A 4S shop or professional modification shop can handle this for you, making it simple and safe. However, it's important to note that such modifications may affect fuel consumption and emission performance. From my own experience, driving feels smoother with the start-stop function disabled, reducing the vibration from frequent engine restarts. But during maintenance, battery life should be checked, as frequent start-stop cycles can accelerate battery aging. Overall, permanently disabling the feature can improve driving comfort, but it's best to ensure legality and consult an expert.
