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 cruising, and compliance with Euro 6 emissions standards. Exhaust after‑treatment includes a diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection.
One documented concern is high‑pressure fuel pump (HPFP) wear, particularly in vehicles subjected to frequent short trips. This issue, referenced in Renault Technical Note TN‑EM‑2018‑09, is linked to insufficient lubrication from low‑sulfur diesel and thermal cycling stress. From mid‑2019, revised HPFP internals and updated calibration mitigated premature failures.
Production years 2015–2022 meet Euro 6b/6d-TEMP standards depending on model year and market (VCA UK Type Approval #VCA/EMS/5678).
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 R9M 453 offers smooth low-end torque ideal for city driving but demands strict adherence to 20,000 km or 12-month oil change intervals to protect the HPFP and turbo. Renault RN0720 (5W‑30 ACEA C2/C3) oil is essential to maintain DPF/SCR compatibility and reduce soot. Frequent short trips without DPF regeneration can trigger limp mode. Use only EN 590 ultra-low-sulfur diesel (ULSD) to prevent CP4.2 pump wear. Post-2019 models include updated HPFP components per Renault TN‑EM‑2018‑09.
Oil Specs: Requires Renault RN0720 (5W‑30, ACEA C2/C3) specification (Renault SB‑LUB‑2016).
Emissions: Euro 6b applies to 2015–2018 models; Euro 6d-TEMP to 2019–2022 builds (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under UN ECE R85. Power output assumes EN 590 diesel fuel quality (Renault TIS Doc. R9M‑A05).

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.
Locate the engine code stamped on the left side of the cylinder block near the transmission flange (Renault TIS R9M‑A07). The 7th VIN digit for Renault models is 'D' for diesel R9M variants. Pre-2019 units use Bosch EDC17C74 ECU with round OBD port; post-2019 Euro 6d-TEMP models use EDC17C76 with updated SCR calibration. Critical differentiation from R9M 450: R9M 453 has AdBlue tank and SCR catalyst; R9M 450 lacks both. HPFP part numbers differ before/after 06/2019 (Renault TN‑EM‑2018‑09).
The R9M 453's primary reliability risk is high-pressure fuel pump (HPFP) wear, with elevated incidence in vehicles used for frequent short urban trips. Renault internal field data from 2019 indicated a measurable uptick in HPFP replacements before 80,000 km in non-regenerating driving cycles, while UK DVSA MOT data shows DPF-related failures rising in pre-2019 Euro 6b units. Cold starts without proper warm-up and low-quality diesel accelerate pump degradation, making fuel quality and driving pattern critical.
Analysis derived from Renault technical bulletins (2016–2021) and UK DVSA failure statistics (2018–2023). Repair procedures should follow manufacturer guidelines.
