The Renault M9R 692 is a 2,148 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) 16-valve design with a variable geometry turbocharger (VGT) and common rail direct injection. This configuration delivers 130 kW (177 PS) and 380 Nm of torque, with the VGT optimizing boost pressure across the rev range for strong low-end pull and sustained power.
Fitted to premium models like the Laguna III GT, Espace V, and Talisman, the M9R 692 was engineered for refined, effortless performance and long-distance comfort. Emissions compliance was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 5 standards from launch and transitioning to Euro 6 in later model years with software and hardware updates.
One documented concern is premature failure of the high-pressure fuel pump, referenced in Renault Technical Note 7712B, often linked to fuel contamination or extended service intervals degrading internal components. In 2014, Renault implemented a revised pump design and updated fuel filter specifications to improve system durability and reliability.
Production years 2010–2014 meet Euro 5 standards; 2015–2018 models meet Euro 6 compliance depending on market (VCA UK Type Approval #VCA/EMS/5679).
The Renault M9R 692 is a 2,148 cc inline‑four turbo‑diesel engineered for executive sedans and MPVs (2010-2018). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong, linear torque and refined cruising. Designed to meet Euro 5 and Euro 6 standards, it balances performance with stringent emissions control.

The VGT turbo provides strong, linear torque ideal for motorway overtaking but requires strict adherence to 20,000 km oil change intervals to protect the turbo and timing chain. Renault RN0720 (5W-30) oil is critical due to its low-ash formulation protecting the DPF. Extended oil life can lead to turbo bearing wear and DPF clogging. The high-pressure fuel pump is sensitive to fuel quality; using EN 590 standard diesel and replacing the fuel filter every 40,000 km is essential. Post-2014 models feature a revised pump; pre-2014 units should have the updated filter per Renault SIB 7712B.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault SIB 7712B). Compatible with ACEA C4 standards.
Emissions: Euro 5 certification applies to 2010-2014 models; Euro 6 applies to 2015-2018 models (VCA Type Approval #VCA/EMS/5679).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across specified fuel grades (Renault TIS Doc. M9R-010).

The Renault M9R 692 was used across Renault's Laguna and Espace platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Espace for NVH refinement-and from 2015 the Talisman models featured minor ECU and emissions hardware updates for Euro 6 compliance, creating potential software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault TIS M9R-002). The 8th VIN digit typically corresponds to the engine type ('R' for M9R series). Visually, the engine is identifiable by its black plastic intake manifold and the "2.2 dCi" badge on the engine cover. Critical differentiation from earlier M9R engines: The 692 variant features a specific Denso HP4 high-pressure fuel pump and a Garrett VGT turbocharger. Service parts, particularly for the fuel system, require verification against the vehicle's production date and ECU software version (Renault SIB 7712B).
The M9R 692's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel or with extended service intervals. Renault internal service data indicates this is a leading cause of no-start conditions for this engine, while owner feedback frequently cites associated fuel economy drops. Adherence to fuel quality standards and preventative maintenance is critical.
Analysis derived from Renault technical bulletins (2012-2018) and aggregated owner-reported failure data (2016-2024). Repair procedures should follow manufacturer guidelines.
