How to disable the auto start-stop function in Audi A4?

The auto start-stop button in Audi A4 is located on the left side of the gear shift, adjacent to the auto hold function, where you can find the start-stop system button. The function is enabled by default when the vehicle leaves the factory, indicated by the "yellow light off". Pressing this button to turn on the "yellow light" will deactivate the start-stop function. Here is an introduction about the auto start-stop system: 1. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving. When it's time to move forward again, the system automatically restarts the engine. 2. By equipping a traditional engine with an enhanced motor that has idle start-stop capability, the system allows the engine to completely shut off when the vehicle meets idle stop conditions. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's start command, rapidly restarting the engine for seamless transition, thereby significantly reducing fuel consumption and exhaust emissions. 3. The activation of the start-stop system must not compromise the normal operation of other vehicle systems. For instance, the system will not shut off the engine under conditions such as when the battery charge is below the threshold, the air conditioning system is in defogging mode, the brake system pressure drops below a certain point, or the vehicle is rolling forward or backward. If the engine does shut off under these circumstances, it will restart immediately without delay.
I find the auto start-stop function in my Audi A4 quite annoying at times, especially in city traffic jams. It keeps shutting off the engine at red lights, only to restart with a loud roar when I press the accelerator, making the drive less smooth. I've developed a habit of pressing the deactivation button every time I get in the car - usually located on the left side of the steering wheel or the center console, marked with a car icon and an 'A'. A light tap temporarily disables it. After driving for over a year, I've noticed that keeping it active in congested areas is particularly inconvenient and might accelerate battery wear. I often remind friends to check their vehicle manuals, as settings vary slightly across different A4 model years, though the operation remains intuitive. My advice is to quickly deactivate it within seconds after starting the engine to avoid unnecessary engine cycling. Overall, turning it off results in smoother driving, especially during urban commutes, making the experience much more pleasant.
As a car enthusiast, I've studied the Audi A4's start-stop system, which is designed to be eco-friendly and fuel-efficient by automatically shutting off the engine when stationary. Turning it off is simple: after starting the vehicle, locate the button with an "A" symbol near the steering wheel or in the center console area, usually holding it down for a few seconds until the light goes off does the trick. I've tried it multiple times, and it reactivates automatically when restarting the car, so it's not a permanent deactivation. If left on, the system repeatedly starts and stops in traffic jams, potentially wearing out the starter and battery while affecting the driving experience. It's fine when driving on highways or in suburban areas, but for city commuting, I always disable it immediately. By the way, Audi's electronic systems are quite smart, but that doesn't stop us from taking manual control.
