Reliability, common problems and owner reviews for the Renault Clio V 1.5 Blue dCi (K9K). Check this before you buy used.

The 1.5 Blue dCi (K9K — the ubiquitous Renault small diesel shared across the entire Renault-Nissan-Dacia range) makes the Clio V a genuinely frugal long-hauler. Standard modern-diesel cautions: DPF clogging on short trips, EGR sooting, injector wear, the timing belt (do it on schedule), and AdBlue/SCR on these Euro 6 cars. With clean fuel and motorway use it's dependable and very economical — one of the most familiar diesels on the road. Wasted on pure city use, but a great motorway commuter. Buy on belt, DPF and injector history.
