The Renault N7Q 711 is a 2,993 cc, V6 turbo‑diesel engine produced between 2008 and 2015. It features a DOHC 24‑valve layout, common‑rail direct injection, and twin variable geometry turbochargers (VGT). In standard form it delivered 173 kW (235 PS) and 450 Nm of torque, with smooth power delivery and refined high‑rpm character suited to executive applications.
Fitted to models such as the Laguna III, Latitude, and Espace IV—specifically the dCi 240 variants—the N7Q 711 was engineered for effortless motorway cruising, strong overtaking response, and premium refinement. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting Euro 5 standards across all production years.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) drive gear, leading to fuel pressure instability and hard starts. This issue, highlighted in Renault Technical Note NTM‑05‑2012, is attributed to marginal lubrication under sustained high-load conditions. From 2012, revised HPFP components with hardened gear surfaces were introduced to improve durability.
All production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/2009/6521).
The Renault N7Q 711 is a 2,993 cc V6 turbo‑diesel engineered for executive sedans and large MPVs (2008–2015). It combines Bosch common‑rail injection with twin variable‑geometry turbochargers to deliver smooth, high-torque performance with refined acoustics. Designed to meet Euro 5 emissions standards, it balances drivability with compliance and premium driving dynamics.

The twin-turbo V6 provides smooth, linear power ideal for long-distance driving but requires strict adherence to 20,000 km oil change intervals using RN0700/ACEA C3 (5W‑40) oil to protect the Bosch CP3.4 high-pressure fuel pump and timing chains. Extended oil intervals increase risk of HPFP drive gear wear and chain stretch. The DPF regeneration cycle must complete uninterrupted—frequent short trips may trigger limp mode. Post-2012 units feature hardened HPFP gears per Renault NTM‑05‑2012.
Oil Specs: Requires Renault RN0700 or ACEA C3 (5W‑40) specification (Renault SIB NTM‑05‑2012). Not compatible with older ACEA B4 oils.
Emissions: Euro 5 certification applies to all 2008–2015 N7Q 711 engines (VCA Type Approval #VCA/EMS/2009/6521). No Euro 6 variants exist for this code.
Power Ratings: Measured under ISO 1585 standards. Output consistent across all markets (Renault PT‑2014).

ISO 1585: Road vehicles — Engine test code
The Renault N7Q 711 was used across Renault's Laguna III, Espace IV, and Latitude platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced transmission mounts in the Espace and revised exhaust manifolds in the Laguna—and from 2012 the HPFP upgrade improved fuel system durability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (Renault TIS N7Q‑ID‑01). The 7th VIN digit for Renault vehicles is 'N' for N7Q applications. Pre-2012 units use Bosch EDC16C39 ECU and HPFP (part 0445010XXX); post-2012 revisions use updated HPFP (0445010YYY) with hardened drive gear. Critical differentiation from N7Q 720: N7Q 711 has lower boost pressure (2.0 bar vs 2.3 bar) and unique injector calibration.
The N7Q 711's primary reliability risk is high-pressure fuel pump (HPFP) drive gear wear, with elevated incidence in vehicles subjected to sustained high-load driving or extended oil intervals. Renault internal data from 2013 indicated over 11% of pre-2012 engines required HPFP replacement before 120,000 km, while UK DVSA MOT records show DPF-related failures rising after 140,000 km in high-mileage executive fleets. Aggressive driving and poor oil quality accelerate HPFP degradation, making oil discipline critical.
