The Renault N7U 700 is a 1,461 cc, inline‑three 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 delivered 66 kW (90 PS), with a higher-output variant reaching 84 kW (115 PS) and torque figures between 220–260 Nm.
Fitted to models such as the Clio V and Captur II, the N7U 700 was engineered for urban efficiency, compact packaging, and compliance with Euro 6d emissions standards. Emissions control was achieved through cooled exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling full Euro 6d certification.
One documented concern is premature wear of the high-pressure fuel pump drive mechanism, highlighted in Renault Service Bulletin RSB‑19‑031. This issue is often linked to marginal oil film strength during frequent cold starts and extended oil change intervals. From 2021, Renault introduced revised camshaft lobe profiles and updated oil specifications to mitigate failure rates.
All production years (2018–2023) meet Euro 6d standards across all markets (VCA UK Type Approval #VCA/EMS/5678).
The Renault N7U 700 is a 1,461 cc inline‑three turbo‑diesel engineered for compact platforms (2018–2023). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver responsive low‑rpm torque and urban fuel efficiency. Designed to meet Euro 6d standards universally, it integrates SCR aftertreatment and balances city driving practicality with regulatory compliance.

The N7U 700 delivers responsive torque ideal for urban driving but requires strict adherence to 15,000 km oil change intervals using Renault RN0720 (5W‑30 ACEA C3) to protect the camshaft-driven high-pressure fuel pump. The Bosch CP4.2 pump is highly sensitive to fuel contamination—only ultra-low-sulfur diesel (EN 590) should be used. AdBlue consumption averages 1.2–1.6 L per 1,000 km; low fluid levels disable restart. Fuel pump drive wear is common after 120,000 km; post-2021 models use improved camshaft lobes per RSB‑19‑031.
Oil Specs: Requires Renault RN0720 (5W‑30, ACEA C3) specification (Renault SIB RSB‑11‑033). Not interchangeable with non-C3 oils.
Emissions: Euro 6d certification applies universally to all 2018–2023 N7U 700 engines (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ISO 1585 standards. 84 kW output requires EN 590 diesel with sulfur <10 ppm (Renault TIS N7U‑A310).

The Renault N7U 700 was used across Renault's Clio V and Captur II platforms with transverse mounting and co-developed with Nissan for shared CMF‑B applications. This engine received platform-specific adaptations—revised oil pan baffling in the Clio and compact AdBlue tank integration in the Captur—and from 2018 the Euro 6d variants adopted SCR aftertreatment with Bosch CP4.2 injection, creating interchange limits. Partnerships enabled Nissan's dCi 90/115 engines to share core architecture. 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‑A105). The 7th and 8th VIN digits indicate engine variant ('70' for N7U 700). All units feature black cam covers and an AdBlue tank under the boot floor. Critical differentiation from earlier dCi 90 engines: N7U 700 uses Bosch EDC17C74 ECU with CP4.2 pump and full Euro 6d compliance. Camshaft part numbers differ before/after 2021—verify via production date (RSB‑19‑031).
The N7U 700's primary reliability risk is camshaft-driven high-pressure fuel pump wear, with elevated incidence in cold-climate urban use and extended oil intervals. Renault internal data from 2022 indicated over 15% of pre-2021 engines required camshaft or pump replacement before 130,000 km, while UK DVSA MOT records show AdBlue/SCR system faults rising in high-mileage city-driven examples. Extended oil intervals and low-quality diesel accelerate CP4.2 pump wear, making fuel quality and service adherence critical.
