The Renault S8U 752 is a 1,749 cc, inline‑four turbo‑diesel engine produced between 2018 and 2023. 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 300 Nm of torque, engineered for responsive low‑rpm performance and compliance with Euro 6d TEMP emissions.
Fitted to models such as the Kadjar, Captur, and Mégane IV—including the dCi 130 variants—the S8U 752 was designed for drivers seeking fuel efficiency, urban drivability, and motorway refinement. Emissions compliance was achieved through a diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, meeting Euro 6d TEMP standards.
One documented concern is premature failure of the high-pressure fuel pump, highlighted in Renault Service Bulletin 6015A. This issue is often linked to fuel contamination or extended service intervals beyond 20,000 km. In 2020, Renault updated the pump design and revised service recommendations to improve reliability.
All production years 2018–2023 meet Euro 6d TEMP (RDE Step 1) standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault S8U 752 is a 1,749 cc inline‑four turbo‑diesel engineered for compact and crossover models (2018–2023). 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 6d TEMP (RDE Step 1), it balances everyday performance with economy.

The VGT turbo provides responsive low-end torque ideal for urban and mixed driving but requires strict adherence to 20,000 km oil change intervals to protect the high-pressure fuel pump and timing chain. Renault RN0720 (5W-30) oil is critical due to its low-SAPS formulation supporting the DPF and SCR systems. Ultra-low-sulfur diesel (EN 590) is mandatory to prevent CP4.2 pump seizure. AdBlue top-ups are required every 10,000–15,000 km; neglect can trigger limp mode. Post-2020 models feature a revised CP4.2 pump per Renault SIB 6015A.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault SIB 6015A). Equivalent to ACEA C2/C3.
Emissions: Euro 6d TEMP (RDE Step 1) applies to all 2018–2023 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output requires EN 590 diesel (Renault TIS Doc. M8010).

The Renault S8U 752 was used across Renault's CMF-CD platform with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Kadjar and revised intake routing in the Captur II—and from 2020 the Mégane IV facelift adopted updated fuel system components, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crank pulley (Renault TIS M7895). The 7th VIN digit indicates engine family ('8' for S8U series). All S8U 752 units feature a black plastic valve cover with “dCi 130” badge. Critical differentiation from S8U 700: S8U 752 uses Bosch EDC17C74 ECU with AdBlue injector and SCR catalyst; S8U 700 lacks SCR. Fuel pump revisions after 06/2020 require updated part numbers per Renault SIB 6015A.
The S8U 752's primary reliability risk is high-pressure fuel pump (CP4.2) failure, with elevated incidence in vehicles using non-EN 590 diesel or exceeding 20,000 km service intervals. Renault internal data from 2021 indicated a measurable uptick in pump replacements before 80,000 km in non-compliant usage, while UK DVSA records show SCR/AdBlue system faults as the second-most common emissions-related MOT defect. Fuel quality and oil specification adherence are critical to longevity.
Analysis derived from Renault technical bulletins (2018–2023) and UK DVSA failure statistics (2019–2023). Repair procedures should follow manufacturer guidelines.
