The Renault R9M 404 is a 1,749 cc, inline‑four turbo‑diesel engine produced between 2018 and 2024. Developed under the Renault–Nissan–Mitsubishi Alliance, it features a common‑rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 96 kW (130 PS), with torque peaking at 300 Nm for responsive urban and highway performance.
Fitted to models such as the Clio V, Captur II, and Arkana—including the Blue dC…
Production years 2018–2024 meet Euro 6d standards across all markets .
The Renault R9M 404 is a 1,749 cc inline‑four turbo‑diesel engineered for compact passenger vehicles (2018–2024). It combines Bosch CP4.2 common‑rail injection with a single variable‑geometry turbocharger to deliver smooth torque and refined efficiency. Designed to meet Euro 6d emissions from launch, it integrates SCR/AdBlue technology alongside EGR and DPF systems.

The Renault R9M 404 was used across Renault's Clio V, Captur II, and Arkana platforms with transverse mounting and shared with Nissan for select compact applications. This engine received platform-specific adaptations—revised engine mounts in the Captur and enhanced thermal shielding in the Arkana—and from 2021 the introduction of updated AdBlue control modules created minor interchange limits. Partnerships enabled Nissan's dCi 130 variant in the Juke (F16). 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 R9M 404 offers refined performance and full Euro 6d compliance, but is highly sensitive to AdBlue fluid quality and vehicle usage patterns. With regular operation (≥20 min/week), ISO 22241 AdBlue, EN 590 diesel, and 20,000 km oil changes, it can be durable beyond 200,000 km. Infrequent use significantly increases AdBlue system risks.
Top issues include AdBlue injector crystallisation (from inactivity or poor fluid), CP4.2 fuel pump wear, NOx sensor drift, and EGR cooler leaks. These are documented in Renault service bulletins NTM 12‑054 and NTM 07‑045, especially in low-mileage or irregularly used vehicles.
The R9M 404 powered the Clio V, Captur II, and Arkana (2019–2024) in Blue dCi 130 form. It was also used by Nissan in the Juke (F16) from 2020–2024 under Alliance agreements, always paired with Euro 6d emissions hardware including AdBlue.
Aftermarket ECU tuning is common on the R9M-404 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.
Excellent for its class. In a Clio V Blue dCi 130, expect ~5.2 L/100km city and ~3.8 L/100km highway, or ~55 mpg UK combined. Real-world mixed driving typically returns 50–58 mpg (UK), assuming good maintenance, EN 590 diesel, and regular AdBlue top-ups.
Yes. The R9M series is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. While chain issues are rare, any timing-related fault codes or unusual noises warrant immediate inspection.
Renault specifies SAE 5W-30 oil meeting RN0720 (ACEA C3) standard. Always use a low-SAPS synthetic oil and change every 20,000 km or annually to protect the DPF, SCR catalyst, turbo, and high-pressure fuel system.
