The third-generation Citroën C3 (codename SX) marked a major stylistic break from its predecessor, adopting a crossover-inspired look with its famous side 'Airbumps' and two-tier headlights. Based on the PF1 platform (and not the CMP of the Peugeot 208 II), it overtly prioritizes ride comfort and spaciousness over pure dynamism. A restyling (facelift) occurred in early 2020, bringing a redesigned front end with standard LED headlights and the integration of 'Advanced Comfort' seats. Although this report focuses on the diesel (BlueHDi) engines, which are very popular with high-mileage drivers and company fleets, the C3 was predominantly sold with petrol (PureTech) engines. The overall reliability of the model is heavily marred by major design flaws in both its engine families (AdBlue tank o
The Citroën C3 III is an extremely endearing city car due to its comfort and looks. However, as an expert, buying a diesel (BlueHDi) version is akin to a financial lottery. The 1.6 BlueHDi is a good engine marred by a faulty AdBlue system (expect 1000 to 1500€ for tank replacement). The 1.5 BlueHDi adds the risk of camshaft chain breakage. If you absolutely must buy a diesel for very high mileage, demand a model whose AdBlue tank has already been replaced recently (with invoice) and, for the 1.5 BlueHDi, prioritize a late 2023 model or plan for the preventive replacement of the chain kit (switching to 8 mm). The petrol (PureTech) versions are no better off due to the wet belt. A purchase that requires extreme vigilance regarding the maintenance history.
