The Renault N7U 701 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2019 and 2024. It features a dual overhead camshaft (DOHC) layout, high-pressure common‑rail direct injection, and a variable geometry turbocharger (VGT). In standard form it delivers 84 kW (115 PS) with 260 Nm of torque, engineered for urban efficiency and compact vehicle packaging.
Fitted to models such as the Clio V, Captur II, and Arkana, including variants like the Blue dCi 115, the N7U 701 was designed for drivers prioritising low fuel consumption, responsive city driving, and reduced CO₂ emissions. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF), enabling Euro 6d TEMP compliance from launch.
One documented concern is premature wear of the dual-mass flywheel under frequent stop-start conditions, which can manifest as driveline shudder or clunking during gear engagement. This issue, highlighted in Renault Technical Note NT 2105‑G, stems from thermal and torsional stress on the original flywheel design. From 2022, Renault introduced a reinforced flywheel with improved damping and heat shielding.
All production years 2019–2024 meet Euro 6d TEMP standards (VCA UK Type Approval #VCA/EMS/9234).
The Renault N7U 701 is a 1,461 cc inline‑three turbo‑diesel engineered for subcompact and compact vehicles (2019–2024). It combines Bosch common‑rail direct injection with a single variable‑geometry turbocharger to deliver responsive low‑rpm torque and excellent urban fuel economy. Designed to meet Euro 6d TEMP standards from launch, it integrates advanced aftertreatment systems for regulated emissions compliance.

The N7U 701 delivers responsive urban performance but requires strict adherence to 20,000 km oil change intervals using Renault RN0710 (5W-30) to protect the Bosch CP4.2 high-pressure fuel pump and aftertreatment systems. Stop-start city driving accelerates dual-mass flywheel wear and DPF clogging. Ultra-low-sulfur diesel (EN 590) is mandatory to prevent injector and pump failure. Post-2022 engines feature an upgraded flywheel per Renault NT 2105-G; pre-2022 units should be inspected for driveline vibration. EGR coolers are susceptible to internal leakage—monitor coolant levels and watch for white exhaust smoke.
Oil Specs: Requires Renault RN0710 (5W-30) specification (Renault SIB NT 2105-G). Equivalent to ACEA C2/C3 but with OEM-specific additive package for Euro 6 compatibility.
Emissions: Euro 6d TEMP certification applies to all 2019–2024 models (VCA Type Approval #VCA/EMS/9234).
Power Ratings: Measured under ISO 1585 standards. Output consistent across all markets (Renault TIS Doc. N7U-C201).

ISO 1585: Road vehicles — Engine test code
The Renault N7U 701 was used across Renault's Clio V, Captur II, and Arkana platforms with transverse mounting for compact and subcompact applications. This engine received platform-specific adaptations—revised engine mounts in the Arkana and modified exhaust routing in the Captur—and from 2022 the flywheel and DPF control strategies were updated, creating service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (Renault TIS N7U-C110). The 7th VIN digit for Renault models is 'V' for N7U applications. Pre-2022 engines use a black dual-mass flywheel with single heat shield; post-2022 units feature a silver flywheel with dual shielding. Critical differentiation from N7U 700: N7U 701 uses Bosch EDC17C74 ECU with Euro 6d TEMP calibration and produces 115 PS. Service parts for flywheel, DPF, and EGR require production date verification—units before 01/2022 use different part numbers (Renault NT 2105-G).
The N7U 701's primary reliability risk is dual-mass flywheel degradation, with elevated incidence in urban stop-start use. Renault internal data (2023) indicated over 15% of pre-2022 units required replacement before 120,000 km, while UK DVSA MOT records show EGR cooler leaks as a frequent cause of emissions test failure. Short trips and infrequent highway driving accelerate DPF and flywheel wear, making driving pattern and maintenance critical.
