The BMW X6 F16 represents the 2nd generation of the BMW X6 model range, which was produced in 2014, 2015, 2016, 2017, 2018, 2019 and 2020. In this material you will find a description of the fuses and relays of the BMW X6 F16 with block diagrams, their locations and photo examples of execution. We will highlight the fuse responsible for the cigarette lighter.

The purpose of fuses and relays, as well as their number in the blocks, may differ from the one presented and depends on the year of manufacture and the level of electrical equipment of your car.

Check the information with your diagram on the paper brochure placed near the unit.

It’s not difficult to figure it out. For example, fuse 13 is responsible for the horn, fuses 25, 128 for the telephone, fuses 5 for the rear window heater, fuses 26, 65, 64, 164, 166 for the seat heater, and so on.
Fuses 36, 37, 143, 162 are responsible for the cigarette lighter. See the diagrams for their location.

Relay elements are located next to the unit. For example, the air suspension and refrigerator relays (if equipped in the car).
Power unit
High-capacity fuses are built into the battery cover to protect the entire circuit.
