Fuses and relays Citroen C3 (F), 2001 - 2010

Sales of the first-generation B-segment Citroën C3 began in 2002. Production was preceded by the 1998 Lumière concept car, which previewed the styling features of the upcoming production hatchback. The model debuted at the 2001 Frankfurt Motor Show. This guide provides detailed fuse box diagrams and panel allocations for the first-generation Citroën C3 (FC/FN code; PF1 platform) produced from model years 2001 through 2010.

Below are the locations, diagrams, and photos of the power distribution boxes. Fuses responsible for the “Cigarette lighter” and “Fuel pump” circuits are highlighted in bold.

Engine Compartment Fuse Box

The distribution box is located on the right-hand side of the engine compartment. Its design and layout vary depending on the model year of the vehicle.
