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 .
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.
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 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.
Aftermarket ECU tuning is common on the S8U-772 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.
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.
