In the Audi A4, the fuse boxes are located in multiple places. The main one is in the engine compartment on the driver's side, protected by a plastic cover.

Another is in the cabin on the left side of the dashboard: open the door and remove the side panel. A third may be in the trunk behind a side trim.

For the schematics, Audi does not always print them clearly on the cover: you can find the legend in the owner's manual or on a sheet included in the fuse box. Alternatively, you can access them through the car's MMI system or specific technical documentation for the model.

It is important to always use a fuse with the same amperage indicated.
