How to Turn Off BMW Intelligent Start-Stop?

[BrantleyRose]

To turn off BMW's intelligent start-stop function: On the engine start button, manually press the Aoff button. Normally, the automatic start-stop system is enabled by default when the key is powered on. To turn it off, simply press the button once. The intelligent start-stop engine automatically shuts off when the vehicle comes to a temporary stop during driving. Taking the BMW 5 Series as an example, its body dimensions are 5087mm in length, 1868mm in width, and 1500mm in height, with a wheelbase of 3108mm. In terms of power, the BMW 5 Series is equipped with 2.0T and 3.0T engines, paired with an upgraded 8-speed automatic manual transmission.

Oh, you're asking about the start-stop function? I used to be really annoyed by it when I first got the car. It's in that button area next to the gear shift—see the one with a circle and an 'A' on it? When the indicator light is on, it means the function is active. Just press it firmly to turn the light off, and it'll deactivate immediately. But heads up, this thing automatically turns back on every time you start the car. If you want to disable it permanently, you'll need to get a hidden program flashed. Once, I chatted with a 4S shop technician about this, and he said if you keep it turned off for too long, the car's computer might lock the disable function, and you'd have to go to the shop to unlock it. Honestly, I'd say just leave it on. When you're stuck in traffic and the engine shuts off from hard braking, keep your foot on the pedal—just ease off the brake slightly, and the engine will start right up. It's pretty flexible!

After driving for twenty years, I find auto start-stop the most annoying, especially how sensitive BMW's system is. Here are two tricks: The straightforward method is pressing the 'A' button on the center console after starting the car—just make sure the dashboard shows 'off'. For a more advanced approach, use the iDrive menu to navigate to Vehicle Settings > Drivetrain/Chassis, then uncheck the 'Eco Display' option to reduce the frequency of auto start-stop. Important reminder for modders: don’t recklessly unplug the battery sensor, or the ECU will throw fault codes. Another handy tip—when the auto start-stop kills the engine instantly with the AC on in summer, lower the AC temperature a bit, and the system won’t dare to shut down. Tested and proven effective.

As a BMW 3 Series commuter, let me show you where the start-stop switch is: After ignition, look at the center console. There's a button with the letter 'A' in the functional area to the left of the gear lever (for F chassis models, it's below the air conditioning panel). Press it, and the dashboard will display a yellow start-stop symbol with a slash, indicating it's turned off. But be careful in rainy days - it's actually good that the start-stop automatically hibernates during wading. Here's a hidden feature: Switching to Sport mode defaults to turning off start-stop, while in ECO mode, you need to long-press the 'A' button for 3 seconds to temporarily disable it. I heard that the new electric platform has changed this to touchscreen control, and owners are complaining that it's not as convenient as physical buttons.
