Frequently asked questions

Which Citroen C4 III engine is the most reliable?

1.5 BlueHDi (DV5) — Maint. Sensitive verdict. The 1.5 BlueHDi (DV5 — shared across the 308/3008/508, Corsa and Grandland) is the frugal long-distance C4 III and a much less anxious buy than the PureTech petrol. Standard modern-diesel cautions: DPF clogging on short trips, EGR sooting, the AdBlue/SCR system (a known fault area on this generation — sensor/pump issues), injector wear, and the timing belt — note the DV5 itself had wet-belt attention on some cars, so verify the belt history. A motorway-driven, on-schedule car is dependable and economical; buy on belt, DPF and AdBlue history.
