Reliability, common problems and owner reviews for the Renault Scénic III 1.5 dCi (K9K). Check this before you buy used.
The 1.5 dCi (K9K) — economical and a little under-engined for the MPV, but the popular, cheap-to-run choice. Usual K9K watch-list: injector wear, turbo failure on oil neglect, EGR/DPF clogging on short trips. Best for high-mileage motorway use with strict oil discipline; the 1.6 dCi or 2.0 dCi suit a fully-loaded Grand Scénic better.
