Reliability, common problems and owner reviews for the Dacia Sandero 1.5 dCi (K9K). Check this before you buy used.

The 1.5 dCi (K9K — the most widely-used small diesel in Europe, shared across the entire Renault-Nissan-Dacia range from Clio to Qashqai to Micra) turns the Sandero into a genuinely frugal long-hauler. It's a proven high-mileage engine but carries the K9K cautions: injector wear (the classic dCi item), turbo oil-feed and DPF/EGR on the later DPF cars, plus the timing belt (do it on schedule). With clean fuel, an on-time belt and a healthy injector set it's a dependable, very economical engine — buy on belt and injector history.
