Where is the horn relay located in the BMW X1?
2 Answers
BMW X1 horn relay is located in the control cabinet or control box. The working principle of the relay is that when a certain voltage is applied to both ends of the coil, the coil generates current, thereby producing an electromagnetic effect. The armature, under the electromagnetic force, overcomes the pulling force of the return spring and is attracted to the iron core, driving the moving contact of the armature to connect with the stationary contact. Taking the 2021 BMW X1 as an example, it belongs to the compact SUV category, with body dimensions of: length 4565mm, width 1821mm, height 1620mm, wheelbase 2780mm, fuel tank capacity 61L, and trunk capacity 505L. The 2021 BMW X1 is equipped with a 1.5T turbocharged engine, with a maximum horsepower of 140PS, maximum power of 103kW, maximum torque of 220Nm, and is paired with a 7-speed dual-clutch transmission.
I always enjoy studying the locations of various components while driving. The horn relay for the BMW X1 is generally found in two places. In most new cars, it's located in the engine compartment fuse box. After opening the hood, look towards the right front wheel—you'll see a rectangular black box. Open its cover to reveal the relay array, and the one labeled with a horn symbol is what you're looking for. In older models, the relay might be hidden in the fuse box near the driver's knee area, which requires removing the storage compartment under the steering wheel to access. Actually, if the horn doesn't sound, don't rush to remove the relay. Instead, have someone press the steering wheel while you listen near the fender for a faint electrical sound from the horn. This can quickly determine whether it's a relay or button issue. The spare tire well actually contains the repair manual, which has detailed diagrams of relay locations—much more accurate than searching online.
