Frequently asked questions
Which Renault Kadjar engine is the most reliable?
1.5 / 1.6 dCi (K9K / R9M) — Maint. Sensitive verdict. The diesels are the high-mileage Kadjar choice — the frugal 1.5 dCi (K9K, the ubiquitous Renault small diesel shared across the range) and the stronger 1.6 dCi (R9M, also in the Qashqai/Mégane). Both are economical and proven; standard cautions apply: DPF clogging on short trips, EGR sooting, injector wear, the timing belt on the K9K (do it on schedule), and AdBlue on later cars. The 1.6 is the better-matched engine for the crossover's weight. A motorway-driven, on-schedule car is a dependable long-hauler — buy on belt, DPF and injector history.
