The Renault R9M 453 is a 1,598 cc, inline‑four turbo‑diesel engine produced between 2015 and 2022. It features a DOHC 16‑valve layout, common‑rail direct injection (up to 2,000 bar), and a variable geometry turbocharger (VGT). In standard form it delivers 96 kW (130 PS) and 320 Nm of torque, with strong low‑rpm response for everyday drivability.
Fitted to models such as the Kadjar, Mégane IV, and Captur, the R9M 453 was engineered for urban efficiency, refined motorway cru…

The Renault R9M 453 is a 1,598 cc inline‑four turbo‑diesel engineered for compact SUVs and hatchbacks (2015–2022). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger to deliver responsive low‑end torque and refined cruising. Designed to meet Euro 6b/6d-TEMP emissions standards, it balances performance with urban efficiency.

The Renault R9M 453 was used across Renault's CMF-CD platform with transverse mounting and co-developed with Nissan as part of the Renault–Nissan–Mitsubishi Alliance. This engine received platform-specific adaptations—reinforced mounts in the Kadjar and revised exhaust routing in the Captur II—and from 2019 the Mégane IV facelift introduced updated AdBlue dosing logic, creating minor ECU interchange limits. 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 453 is generally robust when maintained properly, but early units (2015–2018) are prone to HPFP wear if used mainly for short trips. Later models (2019–2022) feature updated pumps and improved calibration. Using correct oil (RN0720) and EN 590 diesel, plus allowing DPF regeneration, greatly improves longevity.
Top issues include HPFP failure, AdBlue/SCR dosing faults, DPF clogging from urban use, and occasional turbo actuator sticking. These are documented in Renault Technical Notes TN‑EM‑2018‑09 and service bulletins. Fuel and driving pattern significantly influence reliability.
The R9M 453 powered the Kadjar (2015–2022), Mégane IV (2016–2022), and Captur II (2019–2022) as the 1.6 dCi 130. It was also used by Nissan in the Qashqai J11 (2017–2021). All feature Euro 6b or Euro 6d-TEMP compliance with AdBlue SCR systems.
Aftermarket ECU tuning is common on the R9M-453 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 Mégane IV 1.6 dCi 130, real-world consumption is ~5.2 L/100km (city) and ~3.8 L/100km (highway), or ~55 mpg UK combined. Kadjar SUVs average 5.8–6.5 L/100km (43–48 mpg UK). Economy drops significantly if DPF regeneration is frequent.
Yes. The R9M series uses an interference design. 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 RN0720 (5W‑30, ACEA C2/C3) low-SAPS synthetic oil. This protects the DPF and turbo while ensuring HPFP lubrication. Change every 20,000 km or 12 months—whichever comes first—to maintain reliability.
