There are some hidden fuses and relays near the Near Side headlight on some models of the Citroen C3 2002 to 2009.

The models in particular have a diesel engine that require ECU controlled supplemental heating.

Fusebox is Number 15 in the diagram.


These require additional heating of the cabin because there is less excess heat from the engine during its warm up stages than found on petrol models.

The relays and fuses are for the supplemental heater element in the cabin heater and they are often controlled by the engine ECU. The power supply is from the BSM module.
