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…
All production years 2008–2015 meet Euro 5 standards .
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 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.
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 N7Q 711 offers smooth V6 refinement and strong torque, but pre-2012 models are prone to HPFP drive gear wear if oil changes are neglected. Post-2012 revisions improved fuel pump durability. Regular oil changes with RN0700/ACEA C3 oil and avoiding persistent short trips greatly enhance longevity.
Top issues include HPFP drive gear wear, DPF clogging from short trips, twin-turbo actuator failure, and timing chain stretch. These are documented in Renault service bulletins NTM‑05‑2012 and NTM‑06‑2013, with clear OEM repair paths.
The N7Q 711 powered the Laguna III (2008–2015), Espace IV (2008–2015), and Latitude (2010–2015), all as the dCi 240 variant. It was not used in smaller models like Megane or Scénic, nor in Nissan applications.
Aftermarket ECU tuning is common on the N7Q-711 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 Laguna dCi 240, expect ~8.2 L/100km (city) and ~6.0 L/100km (highway), or about 38 mpg UK combined. Real-world mixed driving typically returns 34–40 mpg (UK), depending on driving style and DPF regeneration frequency.
Yes. The N7Q series is an interference engine. If either timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. However, the dual front-mounted chains are generally reliable with proper maintenance.
Renault specifies SAE 5W‑40 oil meeting RN0700 or ACEA C3 standards. Using non-approved oil risks HPFP failure and increased soot buildup. Change every 20,000 km or annually, whichever comes first.
