BMW X3 G01 (2018 – 2024) Fuse Box Location & Diagrams
The BMW X3 G01 (2018–2024) features multiple fuse boxes that protect essential electrical systems and components. This blog provides accurate fuse box locations, detailed fuse diagrams, and fuse assignments, making it easier to identify, inspect, and replace the correct fuse for maintenance or troubleshooting.
Fuse Box Location
Passenger Compartment Fuse Boxes
Two fuse panels are located under the dashboard – the first on the passenger side, the second on the driver’s side (you may need to remove the protective trim – loosen fasteners, arrows, and open the cover). There are also several fuses on the Body Domain Controller, which is located in the passenger-side pillar, behind the trim.
