Renault R9M (1.6 dCi)
1.6 L · inline-4 · turbocharged · diesel · 2011–present
Also known as: r9m, 1.6 dci, energy dci 130, 1.6 dci 130, om626
Renault's 1.6-litre common-rail diesel, developed with Nissan and fitted to the Mégane, Scénic, Kadjar, Qashqai and X-Trail — the engine that replaced the 2.0 dCi in most applications while producing similar output.
It is a modern, tightly packaged engine with a chain drive and a full emissions stack, and its complaints come mostly from the latter: EGR valve and cooler blockage, particulate filter regeneration failure on short journeys, and on later versions the AdBlue system. Turbocharger failures occur and, as with the K9K, are usually a consequence of oil supply rather than an independent fault.
The item worth flagging is oil dilution during repeated failed regeneration, which raises the oil level and thins it. On a car used for short urban trips, a rising level is the engine reporting a problem with its aftertreatment rather than a mistake at the last service.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
