Where is my Volvo s40 fuel gauge fuse?

The fuel gauge fuse for a Volvo S40 is typically located in the fuse box, which is usually found under the dashboard on the driver's side or in the engine compartment. You can refer to the owner's manual for the exact location and fuse number, as it can vary by model year. If the fuel gauge is not functioning, check the fuse to see if it needs to be replaced.
