The Renault S8U 762 is a 2,148 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivers 96 kW (130 PS) and 320 Nm of torque, with higher — output variants reaching 120 kW (163 PS) and 380 Nm.
Fitted to models such as the Mégane III, Scénic III, and Koleos, including the dCi 130 and dCi 160 trims, the S8U 762 was engineered f…
All production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault S8U 762 is a 2,148 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2010–2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The Renault S8U 762 was used across Renault's Mégane III/Scénic III platforms with transverse mounting and licensed to Nissan for shared CMF platform applications. This engine received platform-specific adaptations—reinforced mounts in the Koleos and revised intake manifolds in the Laguna III—and from 2013 the facelifted Mégane III Phase 2 adopted updated HPFP and ECU calibrations, creating interchange limits. Partnerships allowed Nissan's dCi 160 units to share core architecture. All adaptations are documented in OEM technical bulletins.
The S8U 762'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 100,000 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The S8U 762 offers strong torque and refinement, but early models (2010–2012) 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 6012A and DVSA emissions data. Fuel quality and service intervals heavily influence longevity.
The S8U 762 powered the Mégane III (dCi 130/160), Scénic III, Koleos, and Laguna III from 2010–2016. Nissan also used it in the Qashqai and X-Trail (dCi 160) under their alliance agreement. All meet Euro 5 emissions and feature transverse 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 Mégane dCi 130, expect ~5.8 L/100km (city) and ~4.3 L/100km (highway), or ~49 mpg UK combined. The dCi 160 variant averages 5.0–5.5 L/100km (51–56 mpg UK) on mixed routes. Real-world economy depends heavily on DPF regeneration cycles and driving style.
Yes. The S8U 762 is an interference engine. If the 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.
