The fuse for the cigarette lighter in the BMW 7 Series is located in the central console fuse box. The cigarette lighter can only be pressed in when the engine is running or the ignition is turned on. Once the cigarette lighter pops out, it can be removed for lighting cigarettes. How to use the cigarette lighter: Press the button, and after 10-60 seconds, the cigarette lighter device will pop up with a slight sound. Be sure to pick it up by the popped side and use the other side to light the cigarette. A gentle touch to the cigarette will ignite it. Using a lighter while driving poses safety hazards, so using the cigarette lighter is highly significant. Cigarette lighter location: The location of the cigarette lighter is not fixed and varies depending on the car model. Some cigarette lighters are buttons with a cigarette icon, some are located near the USB port, and others are positioned near the rear air conditioning vents.
As a long-time owner of a BMW 740, I've experienced cigarette lighter failures. The fuse is usually located in the left rear fuse box in the trunk, where the cover clearly marks its position for easy identification. Open the inner trunk panel and check the diagram legend – the cigarette lighter fuse is typically labeled as F56 or similar. Once blown, the cigarette lighter loses power. Why does it blow? It could be due to using high-power devices like fast chargers or car refrigerators. When replacing the fuse, always choose the same amperage rating – never substitute with different sizes. I recommend regular inspections to prevent minor issues from affecting travel convenience. For safety, disconnect the battery's negative terminal before any work. This issue is quite common – my friend's car had it too. Learning self-inspection can save you dealership repair costs.
I've worked on cars, so straight to the point: The cigarette lighter fuse for the BMW 740 is located in the fuse box on the left side of the trunk. Open the left cover panel in the trunk to see the array of fuses. Refer to the manual or the icons on the cover panel for the corresponding fuse number, typically something like F56. If it's blown, the filament usually appears blackened or broken. You can confirm this with a multimeter. The replacement steps are simple—first disconnect the power, remove the old fuse, and replace it with a new one of the same amperage. Avoid using overly large devices to prevent overload. By the way, BMW's fuse box design is centralized and rear-mounted for easy maintenance.
