How to Locate the Fuse Boxes and Understand Their Schematics in an Audi A4

Model: Audi A4 B9 - Years 2014-2024
Part: Fuse box

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.

How to Reset the Central Locking of the Volkswagen Golf 4?

If the central locking system of the Volkswagen Golf 4 is not working, it is likely necessary to reset the system: to do this, open the driver's door and detach the side panel of the dashboard next to the steering wheel. Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14. To reset the system, remove this fuse from its housing, then reinsert it or replace it with a new one of the same amperage: this will reset the central locking system.
