The Renault M9R 832 is a 1,995 cc, inline‑four turbo‑diesel engine produced between 2006 and 2018. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 96 kW (130 PS), with higher — output variants reaching 130 kW (177 PS) and torque figures between 320–380 Nm.
Fitted to models such as the Laguna III, Mégane III, Scénic III, and Koleos, the M9R 832 was engineered for a balance of fu…
Production years 2006–2010 meet Euro 4 standards; 2011–2014 models meet Euro 5; 2015–2018 variants meet Euro 6 depending on market .
The Renault M9R 832 is a 1,995 cc inline‑four turbo‑diesel engineered for mid‑size and SUV platforms (2006–2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 4 through Euro 6 standards (depending on model year), it balances everyday performance with economy.

The Renault M9R 832 was used across Renault's Laguna III, Mégane III, and Scénic III platforms with transverse mounting and co-developed with Nissan for shared CMF‑C/D applications. This engine received platform-specific adaptations—reinforced mounts in the Koleos and revised cooling in the Talisman—and from 2015 the Euro 6 variants adopted updated EGR coolers and SCR aftertreatment, creating interchange limits. Partnerships enabled Nissan's dCi 130/160/177 engines to share core architecture. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M9R 832 offers strong torque and refinement, but early models (2006–2011) suffer from dual-mass flywheel and CP3 pump issues. Post-2012 revisions improved durability. With strict adherence to oil changes (15,000 km) and use of EN 590 diesel, well-maintained examples can exceed 250,000 km.
Top issues include dual-mass flywheel failure, Bosch CP3 fuel pump wear, EGR clogging, and DPF regeneration problems. These are documented in Renault service bulletins RSB‑12‑045 and RSB‑10‑021. Urban driving and poor maintenance accelerate these failures.
The M9R 832 powered the Laguna III, Mégane III, Scénic III, Koleos, and Talisman from 2006–2018. It was also used by Nissan in Qashqai, X-Trail, and Navara as the dCi 130/150/170. Output ranged from 130 to 177 PS across applications.
Aftermarket ECU tuning is common on the M9R-832 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Mégane dCi 130, expect ~5.8 L/100km city and ~4.3 L/100km highway, or ~52 mpg UK combined. Real-world mixed driving typically returns 45–55 mpg (UK). Economy drops significantly with DPF issues or short-trip driving.
Yes. The M9R series is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and generally durable with proper oil maintenance.
Renault specifies SAE 5W‑30 oil meeting RN0720 (ACEA C3) standard. Always use low-ash, low-SAPS oil to protect the DPF and turbo. Change every 15,000 km or annually—whichever comes first.
