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…
All production years (2018–2023) meet Euro 6d standards across all markets .
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The N7U 700 offers compact efficiency and full Euro 6d compliance, but early models (2018–2020) suffer from camshaft-driven fuel pump wear and CP4.2 pump issues. Post-2021 revisions improved reliability. With strict adherence to oil changes (15,000 km) and use of EN 590 diesel, well-maintained examples can exceed 200,000 km.
Top issues include camshaft lobe wear driving the CP4.2 pump, Bosch CP4.2 internal failure, AdBlue/SCR system faults, and EGR valve sticking. These are documented in Renault service bulletins RSB‑19‑031 and RSB‑10‑021. Cold starts and short-trip driving accelerate these failures.
The N7U 700 powered the Clio V and Captur II from 2019–2023. It was also used by Nissan in the Micra K14 as the dCi 90. Output ranged from 90 to 115 PS across applications, all meeting Euro 6d standards.
Aftermarket ECU tuning is common on the N7U-700 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.
In a Clio dCi 90, expect ~4.2 L/100km city and ~3.4 L/100km highway, or ~67 mpg UK combined. Real-world mixed urban driving typically returns 55–65 mpg (UK). Economy drops significantly with short trips or AdBlue system issues.
Yes. The N7U series is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and generally durable with proper oil maintenance.
Renault specifies SAE 5W‑30 oil meeting RN0720 (ACEA C3) standard. Always use low-ash, low-SAPS oil to protect the DPF, SCR, and turbo. Change every 15,000 km or annually—whichever comes first.
