In 2010, the second-generation Citroën C4 (B7) was unveiled in Paris. Concurrently, the decision was made to discontinue the three-door hatchback, meaning the new model was initially produced exclusively as a five-door hatchback (the sedan was not officially introduced until late 2012). This guide provides a detailed look at the power distribution and fuse box diagrams for the second-generation Citroën C4 (PF2 platform; B7 code) covering the 2011, 2012, 2013, 2014, 2015, 2016, 2017, and 2018 model years.
Here you will find the locations and photos of the power distribution modules. The fuses protecting the “Cigarette lighter” and “Fuel pump” circuits are highlighted in bold.
Engine Compartment
