bmw x1 cigarette lighter fuse location box diagram e84 and relay with assignment and 2015 BMW 1 Series Cigarette

Here are the horn wiring diagrams so you can see how the system works, the fuses do not match the ones in your image, so I am wondering if this is the correct label for your car

The most common reasons for the cigarette lighter (or power socket) fuse blowing are: Current overload: connecting devices that draw more current than the fuse is designed to handle (such as high-power chargers, air compressors, power inverters, etc.) can cause the fuse to blow

Please let us know what you find

Thanks for the reply
