Reliability, common problems and owner reviews for the Renault Scénic III 2.0 dCi (M9R). Check this before you buy used.
The 2.0 dCi (M9R) is the strongest Scénic diesel — the well-regarded Alliance unit (also in Laguna/Qashqai/X-Trail), genuinely capable for a fully-loaded Grand Scénic. Chain-driven (rated ~160k km, can stretch → cold-start rattle), with the known DPF-pressure-sensor pipe fault, city DPF clogging, and occasional turbo/crank-liner wear on hard use. Use low-ash C3 oil and it covers big distances.
