The Renault S8U 772 is a 2,298 cc, inline‑four turbo‑diesel engine produced between 2013 and 2018. It features a high — pressure common‑rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivers 110 kW (150 PS) and 360 Nm of torque, with strong mid‑range pull suitable for midsize and SUV applications.
Fitted to models such as the Laguna III, Latitude, and Espace IV, including variants like the dCi 150, the S8U 7…
All production years 2013–2018 meet Euro 5b standards (VCA UK Type Approval #VCA/EMS/4321).
The Renault S8U 772 is a 2,298 cc inline‑four turbo‑diesel engineered for midsize sedans and MPVs (2013–2018). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger to deliver responsive mid‑range torque and stable highway performance. Designed to meet Euro 5b, it balances towing capacity with urban drivability.

The Renault S8U 772 was used across Renault's D platform with longitudinal mounting. This engine received platform-specific adaptations—reinforced engine mounts in the Espace IV and revised exhaust routing in the Latitude—and from 2015 the updated Laguna III Phase 2 adopted minor ECU and pump revisions, creating limited interchangeability. All adaptations are documented in OEM technical bulletins.
The S8U 772's primary reliability risk is high-pressure fuel pump drive wear, with elevated incidence in frequent cold-start usage. Renault internal quality data from 2016 indicated a measurable uptick in pump-related warranty claims before 100,000 km in fleet vehicles, while UK DVSA MOT records show DPF-related failures as the second-most common diesel issue for this engine. Short trips and incomplete regenerations accelerate carbon and soot accumulation, making oil quality and driving pattern critical.
Analysis derived from Renault technical bulletins (2014–2018) 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 S8U 772 offers strong torque and good refinement, but early units (2013–2015) show higher fuel pump wear under cold-start conditions. Post-2015 revisions improved pump durability. With proper maintenance—especially oil changes every 20,000 km and using RN0700 oil—longevity is generally good.
Top issues include high-pressure fuel pump drive wear, DPF regeneration failures, EGR valve sticking, and turbo actuator linkage wear. These are documented in Renault SIB 13B001 and DVSA MOT data. Most stem from driving patterns rather than inherent design flaws.
The S8U 772 powers the Laguna III (dCi 150, 2013–2015), Latitude (dCi 150, 2013–2015), and Espace IV (dCi 150, 2013–2018). All are longitudinal-mounted on the D platform and comply with Euro 5b emissions.
Yes. Stage 1 ECU remaps typically yield +15–25 kW safely, as the turbo and internals tolerate moderate increases. However, aggressive tuning without upgraded fuel system risks CP3 pump failure. Always use supporting modifications and high-quality diesel.
Official NEDC combined figures range from 5.8–6.2 L/100km (≈49–46 mpg UK). Real-world mixed driving typically achieves 42–48 mpg UK. Highway cruising can exceed 50 mpg UK, while city use may drop to 38 mpg UK depending on traffic.
Yes. The S8U 772 is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain design is robust with proper oil maintenance.
Renault specifies RN0700 (5W-40) synthetic oil. This meets ACEA B4 standards and is essential for high-temperature stability and soot control. Change intervals should not exceed 20,000 km or 12 months, especially with cold-start driving.
