Frequently asked questions
Which Renault Mégane IV engine is the most reliable?
1.5 dCi / Blue dCi (K9K) — Maint. Sensitive verdict. The 1.5 dCi (K9K — the ubiquitous Renault small diesel shared across the entire Renault-Nissan-Dacia range) is the high-mileage, low-cost Duster II choice and a classic budget workhorse, available with 4x4. Standard modern-diesel cautions: DPF clogging on short trips, EGR sooting, injector wear, the timing belt (do it on schedule), and AdBlue/SCR on the later Blue dCi cars. With clean fuel and an on-time belt it's dependable and very economical — exactly the rugged, cheap-to-run package the Duster is known for. Buy on belt, DPF and injector history.
