The Renault M9T 880 is a 2,298 cc, inline‑four turbo‑diesel engine produced between 2014 and 2023. It features a DOHC 16‑valve layout, common‑rail direct injection, and a variable geometry turbocharger (VGT), delivering 130 kW (177 PS) and 380 Nm of torque. The high — pressure fuel system enables precise combustion control for responsive low‑rpm performance.
Fitted to models such as the Renault Master, Trafic, and Alaskan, as well as the Nissan NV300 and Navara, the M9T 8…
All production years 2014–2023 meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault M9T 880 is a 2,298 cc inline‑four turbo‑diesel engineered for light commercial and pickup applications (2014–2023). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger to deliver high torque at low engine speeds and robust load-carrying performance. Designed to meet Euro 6 standards from launch, it integrates advanced aftertreatment for urban compliance.

The Renault M9T 880 was used across Renault's commercial platforms with longitudinal mounting and co-developed with Nissan for shared use in European and global markets. This engine received platform-specific adaptations—reinforced sump in the Master and dual-mass flywheel tuning in the Alaskan—and from 2018 the Trafic III received updated engine mounts and revised ECU calibration, creating minor interchange limits. Partnerships enabled Nissan to deploy the same unit in the Navara and NV300. All adaptations are documented in OEM technical bulletins.
The M9T 880's primary reliability risk is high-pressure fuel pump (HPFP) wear in urban or low-load use, with elevated incidence in stop-start delivery cycles. Renault internal field data from 2019 indicated a notable share of pre-2018 pumps requiring replacement before 100,000 km, while UK DVSA MOT records show DPF-related failures rising in vehicles with predominantly short journeys. Extended idling and poor fuel quality accelerate pump and aftertreatment stress, making oil/fuel specification adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M9T 880 offers strong torque and Euro 6 compliance, but early units (2014–2017) had HPFP reliability concerns. Post-2018 revisions improved pump durability significantly. With correct oil (RN0720), quality ULSD, and regular long-distance driving to enable DPF regeneration, well-maintained examples can exceed 250,000 km.
Top issues include high-pressure fuel pump wear, DPF regeneration failures from short trips, EGR cooler leaks, and turbo actuator drift. These are documented in Renault SIB 3057A and Nissan TSB NTB18-045. Fuel quality and driving pattern heavily influence longevity.
The M9T 880 powers the Renault Master III, Trafic III, and Alaskan (all dCi 170 variants) from 2014–2023. It’s also used in the Nissan NV300 and base-model Navara (D23) with 170 PS output. All meet Euro 6 from launch.
Yes. ECU remaps typically yield +20–30 kW and +60–80 Nm on stock hardware. The engine responds well to stage 1 tuning, but HPFP and turbo durability must be monitored. Supporting upgrades (intake, exhaust, intercooler) improve reliability under increased load.
In a Renault Trafic dCi 170, expect ~7.2 L/100km (city) and ~5.8 L/100km (highway), or ~42 mpg UK combined. Real-world figures vary by load and route—commercial vans average 38–45 mpg UK. DPF health and driving style significantly affect consumption.
Yes. The M9T series uses an interference design. Timing chain failure or jump can cause piston-to-valve contact, resulting in catastrophic damage. However, the front-mounted chain is robust; no widespread timing issues are documented in OEM bulletins.
Renault specifies RN0720 (5W-30, ACEA C3) oil. This low-SAPS formulation protects the DPF and turbo. Change every 20,000 km or annually. Using non-approved oil risks aftertreatment clogging and HPFP wear.
