Reliability, common problems and owner reviews for the Renault Scénic III 1.6 dCi (R9M). Check this before you buy used.
The 1.6 dCi (R9M, 'Energy dCi') is the newer, cleaner diesel — torquier and more refined than the 1.5, and a better match for the heavier Grand Scénic. It's a modern common-rail unit (chain-driven), so the cautions are DPF/EGR on short trips and injection/turbo care; some early R9M cars needed attention to the timing-chain area and oil discipline. A documented, motorway-driven example is a strong, economical engine.
