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…
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 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.
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.
Analysis derived from Renault technical bulletins (2020–2024) and UK DVSA failure statistics (2021–2024). 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 N7U 701 offers excellent urban efficiency and refinement, but pre-2022 models suffer from dual-mass flywheel and EGR cooler issues. Post-2022 revisions improved durability. With proper maintenance—especially using correct oil and ensuring occasional highway driving—well-cared-for examples can exceed 200,000 km reliably.
Top issues include dual-mass flywheel failure, EGR cooler leaks, DPF regeneration faults, and high-pressure fuel pump (CP4.2) seizure. These are documented in Renault service bulletins NT 2105-G and NT 1402-11. Urban driving exacerbates most of these problems.
The N7U 701 powered the Clio V, Captur II, and Arkana from 2019–2024 as the Blue dCi 115. It also appeared in the Nissan Juke (F16) under OEM partnership. All are Euro 6d TEMP compliant from launch.
Limited tuning potential due to small displacement and emissions constraints. Stage 1 remaps typically yield +8–10 kW (125–130 PS) and +20–30 Nm, but increase stress on the flywheel and DPF. Not generally recommended for daily-driven urban vehicles.
In a Clio Blue dCi 115, expect ~4.2 L/100km city and ~3.5 L/100km highway, or ~67 mpg UK combined. Real-world mixed driving typically returns 60–65 mpg (UK). Economy suffers significantly with frequent short trips due to DPF regenerations.
Yes. The N7U series is an interference engine. If the timing chain fails or jumps (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain is generally durable with proper oil changes.
Renault specifies 5W-30 synthetic oil meeting RN0710 standard. This is critical for protecting the CP4.2 fuel pump and ensuring Euro 6 aftertreatment compatibility. Change intervals should not exceed 20,000 km or 12 months, especially in urban use.
