2012-2018 BMW 3-Series (F30/F31/F34) fuse box diagram

The BMW 3-Series from 2011 to 2019 (generations F30, F31, F34) has fuse boxes inside the car. These boxes contain fuses and relays that control various electrical components like lights and power windows. If you need to replace a fuse or check which one controls a specific function (like the radio or air conditioning), you can find diagrams for each year and model (such as 316i, 320i, 328d) online. These diagrams show you where the fuse panels are located and what each fuse is for, making it easier to troubleshoot electrical issues in your BMW.
