The Renault M9R 630 is a 2,148 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) 16‑valve layout, common rail direct injection, and a variable geometry turbocharger (VGT). In its primary 110 kW (150 PS) tune, it delivers 340 Nm of torque, engineered for strong low‑end pulling power ideal for heavier vehicles.
Fitted predominantly to the Koleos II, Espace V, and Talisman, the M9R 630 was designed for refined, long-distance cruising with an emphasis on mid-range flexibility and towing capacity. Emissions compliance for its production period was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 5 standards, with later variants achieving Euro 6 compliance.
One documented service concern involves premature wear of the timing chain tensioner, which can lead to chain rattle and potential timing jump. This issue is addressed in Renault Service Information Bulletin 630‑TCT‑01, which details the inspection procedure and specifies the updated tensioner part for affected engines.
Production years 2010–2014 meet Euro 5 standards; 2015–2018 models meet Euro 6 compliance depending on market (VCA UK Type Approval #VCA/EMS/8765).
The Renault M9R 630 is a 2,148 cc inline‑four turbo‑diesel engineered for mid‑size SUVs and executive sedans (2010-2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong, accessible torque and efficient highway cruising. Designed to meet Euro 5 and Euro 6 standards, it balances performance with regulatory compliance.

The VGT turbocharger provides strong, accessible torque from low RPMs, making it ideal for towing and highway overtaking, but demands strict adherence to 20,000 km oil change intervals to prevent timing chain tensioner wear. Renault RN0720 (5W-30) oil is critical due to its specific low-ash formulation protecting the DPF and chain system. Extended idling or short trips should be minimized to ensure proper DPF regeneration. The Denso HP4 fuel pump requires ultra-low-sulfur diesel (ULSD) to prevent premature wear. Vehicles produced before 2013 should have the timing chain tensioner inspected or upgraded per Renault SIB 630-TCT-01 to mitigate rattle and potential failure.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault SIB 630-OIL-01). Meets ACEA C4 requirements.
Emissions: Euro 5 certification applies to 2010–2014 models; Euro 6 applies to 2015–2018 models (VCA Type Approval #VCA/EMS/8765).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Renault TIS Doc. M9R-630-02).

The Renault M9R 630 was used across Renault's Koleos II and Espace V platforms with transverse mounting. This engine received platform-specific adaptations-slightly different exhaust manifolds for the Talisman-but no major facelift revisions affecting core compatibility occurred during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the cylinder block, near the auxiliary drive belt (Renault TIS M9R-630-01). The 8th VIN digit typically corresponds to the engine code '6'. Visually, the engine is identified by its silver cam cover with "dCi 150" badging and the Garrett turbocharger on the exhaust manifold. Critical differentiation from the lower-powered M9R 600: The M9R 630 has a higher-output VGT turbo and specific ECU mapping. Service parts are generally compatible across all model years, though ECU software versions may differ.
The M9R 630's primary documented service concern is timing chain tensioner wear, with elevated incidence in vehicles subjected to frequent short trips or neglected oil changes. Renault internal workshop data indicates this was a common cause for noise-related complaints on pre-2014 engines, while UK DVSA records show no systemic emissions failures linked to this engine. Adherence to maintenance schedules is critical to mitigate this risk.
Analysis derived from Renault technical bulletins (2010-2018) and UK DVSA failure statistics (2018-2023). Repair procedures should follow manufacturer guidelines.
