The Renault S8U 763 is a 1,995 cc, inline‑four turbo‑diesel engine produced between 2018 and 2023. 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 380 Nm of torque, engineered for responsive low — end performance and compliance with Euro 6d TEMP emissions.
Fitted to models such as the Renault Talisman, Espace, and Koleos, the S8U 763 was design…
All production years 2018–2023 meet Euro 6d TEMP standards .
The Renault S8U 763 is a 1,995 cc inline‑four turbo‑diesel engineered for mid‑size and large SUV/sedan applications (2018–2023). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger and AdBlue SCR aftertreatment to deliver strong low‑rpm torque and strict Euro 6d TEMP compliance. Designed for refined daily driving and towing, it balances performance with stringent emissions control.

The Renault S8U 763 was used across Renault's CMF-CD and CMF-EV platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Espace and modified exhaust routing in the Koleos—and from 2020 the Talisman facelift adopted updated ECU calibration for improved cold-start emissions, creating minor software 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. 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 763 offers strong refinement and Euro 6d compliance, but early units (2018–mid-2020) had HPFP reliability concerns. Post-2020 revisions improved fuel system durability. With strict use of EN 590 diesel, RN0720 oil, and full-service adherence, it can be dependable beyond 200,000 km.
Top issues include high-pressure fuel pump wear, AdBlue/SCR system faults, DPF regeneration challenges, and minor turbo oil leaks. These are documented in Renault SIB 77 12 01 and DVSA emissions data. Fuel and oil quality are critical mitigating factors.
The S8U 763 powered the Renault Talisman (2018–2023), Espace (2018–2022), and Koleos (2019–2023), all as the dCi 150 variant. It was not licensed to other manufacturers and is exclusive to Renault’s CMF-platform vehicles.
Aftermarket ECU tuning is common on the S8U-763 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 WLTP combined is ~5.3 L/100km (~53 mpg UK). Real-world mixed driving yields 5.8–6.5 L/100km (43–49 mpg UK). Highway efficiency can reach 4.9 L/100km (58 mpg UK), while city driving may exceed 7.0 L/100km.
Yes. Like all modern DOHC diesels, it is an interference design. Timing chain failure—though rare—can cause catastrophic valve/piston contact. Chain durability is generally good, but oil degradation must be avoided.
Renault specifies RN0720 (ACEA C2/C3) 5W-30 synthetic oil. This low-SAPS formulation protects the DPF and SCR. Never use older RN0700 or non-C2/C3 oils, as ash buildup can clog aftertreatment systems prematurely.
