The Renault V9X 891 is a 2,993 cc, 60° V6 turbo‑diesel engine produced between 2009 and 2018. It features common rail direct injection, a single variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC) per bank. In standard form it delivers 173 kW (235 PS) and 450 Nm of torque, with higher — output variants reaching 177 kW (241 PS) and 520 Nm.
Fitted to premium models such as the Laguna III, Latitude, and Vel Satis, including the dCi 240 and dCi 250 trims, the V9X 8…
All production years 2009–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/8912).
The Renault V9X 891 is a 2,993 cc V6 turbo‑diesel engineered for executive sedans and large SUVs (2009–2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver smooth, high-torque performance and refined cruising. Designed to meet Euro 5 standards, it balances power delivery with emissions compliance.

The Renault V9X 891 was used across Renault's Laguna III/Latitude platforms with longitudinal mounting and licensed to Nissan and Infiniti for shared FM platform applications. This engine received platform-specific adaptations—reinforced mounts in the Vel Satis and revised intake manifolds in the Latitude—and from 2013 the facelifted Laguna III Phase 2 adopted updated HPFP and ECU calibrations, creating interchange limits. Partnerships allowed Infiniti's M30d and Nissan's 30d units to share core architecture. All adaptations are documented in OEM technical bulletins.
The V9X 891's primary reliability risk is high-pressure fuel pump (HPFP) failure on early builds, with elevated incidence in vehicles using inconsistent fuel quality or extended service intervals. Renault internal data from 2014 indicated a notable share of pre-2013 engines requiring HPFP replacement before 120,000 km, while UK DVSA records show EGR/DPF-related MOT failures in high-mileage urban examples. Short-trip driving and poor-quality diesel accelerate pump and emissions system degradation, making fuel quality and service adherence critical.
Analysis derived from Renault technical bulletins (2012–2016) and UK DVSA failure statistics (2015–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The V9X 891 offers smooth V6 torque and refinement, but early models (2009–2012) are prone to HPFP failures. Post-2013 revisions significantly improved fuel system durability. With consistent use of EN 590 diesel, regular oil changes (15,000 km), and proper DPF management, well-maintained examples can exceed 200,000 km reliably.
Top issues include high-pressure fuel pump failure (pre-2013), EGR/DPF clogging from short trips, turbo actuator sticking, and occasional injector leaks. These are documented in Renault SIB 6015B and DVSA emissions data. Fuel quality and service intervals heavily influence longevity.
The V9X 891 powered the Laguna III, Latitude, and Vel Satis from 2009–2015 in dCi 240/250 trims. Nissan and Infiniti also used it in the Maxima QX 30d and M30d (2010–2014) under their alliance agreement. All meet Euro 5 emissions and feature longitudinal mounting.
Yes. Stage 1 ECU remaps typically yield +20–30 kW safely, as the stock internals handle increased torque. Supporting upgrades (intake, exhaust, intercooler) enhance reliability. However, aggressive tuning without HPFP upgrades may accelerate fuel system wear, especially on pre-2013 units.
In a Laguna dCi 240, expect ~7.8 L/100km (city) and ~5.6 L/100km (highway), or ~42 mpg UK combined. Real-world economy depends heavily on DPF regeneration cycles, vehicle weight, and driving style.
Yes. The V9X 891 is an interference engine. If either timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. While chain failures are rare, any unusual noise or timing-related DTCs require immediate inspection.
Renault specifies 5W-30 synthetic oil meeting RN0720 (or ACEA C3 equivalent). Always use low-SAPS oil to protect the DPF and turbo. Change intervals should not exceed 15,000 km or 12 months to maintain HPFP and chain lubrication.
