Fuse box diagram (fuse layout), location, and assignment of fuses BMW X7 xDrive40i, xDrive50i, M50i, xDrive30d, xDrive40d, M50d (G07) (2019, 2020, 2021, 2022).
Checking and Replacing Fuses
The fuses protect electrical systems against excessive current. When a device does not work, you must check the fuse element inside the blade fuse for a break/melt.
Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Check those fuses first that protect the failed component, but check all the fuses before deciding that a blown fuse is not the cause. Replace any blown fuses with another with the same amperage (same color) and check the component’s operation.
Information on the fuse types and locations, as well as the positions of any other fuse boxes, is found on a separate sheet in the fuse box.
WARNING!
- Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/or disengaged.
- Incorrect and repaired fuses can overload electrical lines and components. There is a risk of fire. Never attempt to repair a blown fuse. Do not replace a nonworking fuse with a substitute of another color or amperage rating.
- If the replaced fuse blows again, contact an authorized dealer.
