The first-generation Citroën C4 (internal code name LC for the 5-door sedan, LA for the 3-door coupé) marked a major stylistic and technological break for the chevron brand, replacing the aging Xsara. Launched in 2004, it stood out with its bold design (especially the Coupé version with its split rear window), its fixed-hub steering wheel grouping controls, its central digital display, and unprecedented equipment for the category (perfume diffuser, AFIL lane departure warning). The late 2008 facelift (Phase 2) brought slight aesthetic touches, an improvement in interior finish, and a multimedia system update. However, this facelift primarily marked a turning point under the hood: the abandonment of the robust historical petrol engines (TU/EW) in favor of the "Prince" engine family (VTi and
The first-generation Citroën C4 is a car with two faces. If you are looking for a petrol engine, it is imperative to prioritize a Phase 1 (2004-2008) equipped with the 1.6i 16V (110 hp) or 2.0i 16V (138 hp) engines. These older generation (TU/EW) blocks are indestructible and will protect you from ruinous mechanical failures, even if you have to accept sometimes capricious electronics. Conversely, avoid the petrol versions of Phase 2 (2008-2010) equipped with VTi and THP engines, whose reliability is disastrous (timing chain, oil consumption). For diesel, the 1.6 HDi 90 or 2.0 HDi 136 are good choices for high-mileage drivers, but the very common 1.6 HDi 110 requires a pristine maintenance history to avoid turbo failure.
