The Peugeot R9M is a 1,598 cc, inline‑four turbo‑diesel engine produced between 2013 and 2021 under the Renault — Nissan — Mitsubishi Alliance. It features a DOHC 16‑valve layout, common‑rail direct injection, and a variable geometry turbocharger (VGT). In standard form it delivered 96 kW (130 PS); higher — output variants produced 120 kW (163 PS) with torque figures between 300–380 Nm.
Fitted to models such as the Peugeot 308 II, 3008 II, and 5008 II—including the 1.6 Blue…
All production years (2013–2021) meet Euro 6b or later standards (VCA UK Type Approval #VCA/EMS/8765). No Euro 5 variants were produced.
The Peugeot R9M is a 1,598 cc inline‑four turbo‑diesel engineered for compact and mid‑size SUVs and hatchbacks (2013–2021). It combines Bosch CP4.2 common‑rail injection with a single variable‑geometry turbocharger to deliver responsive low‑rpm torque and low CO₂ emissions. Designed to meet Euro 6b standards from launch, it integrates AdBlue SCR for NOx control alongside EGR and DPF systems.

The Peugeot R9M was used across Peugeot's EMP2 platform vehicles with transverse mounting and co-developed within the Renault-Nissan-Mitsubishi Alliance. This engine received platform-specific calibrations—revised AdBlue tank layout in the 5008 II and updated ECU mapping in the 3008 II GT—and from 2018 the facelifted 308 II adopted Euro 6d-TEMP compliance with enhanced SCR control, creating software interchange limits. Alliance partnerships allowed Renault's R9M (dCi 130/160) and Nissan's M9R-derived units to share core architecture. All adaptations are documented in OEM technical bulletins.
The R9M's primary reliability risk is high-pressure fuel pump (HPFP) failure in pre-2018 units, with elevated incidence in vehicles using contaminated or low-quality diesel. Peugeot internal quality reports from 2017 noted a measurable increase in HPFP warranty claims before 80,000 km in regions with inconsistent fuel standards, while UK DVSA data shows AdBlue system faults as a recurring MOT advisory item in high-mileage examples. Short-trip urban use and infrequent AdBlue top-ups accelerate DPF/SCR issues, making fuel quality and fluid maintenance critical.
Analysis derived from Peugeot technical bulletins (2013–2021) and UK DVSA failure statistics (2018–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The R9M offers strong performance and refinement but early units (2013–2017) have HPFP reliability concerns. Post-2018 revisions improved fuel pump durability. With strict adherence to oil changes, use of quality diesel, and regular AdBlue top-ups, well-maintained examples can exceed 250,000 km.
Top issues include high-pressure fuel pump failure (pre-2018), AdBlue/SCR system faults, EGR cooler clogging, and turbo actuator sticking. These are documented in Peugeot service bulletins TSB-16-D09 and SIB D-16-04. Fuel quality and driving patterns significantly influence reliability.
The R9M powers the 308 II (2013–2021), 3008 II (2016–2021), and 5008 II (2017–2021) as 1.6 BlueHDi 120/165 variants. It is also used by Renault (Mégane IV, Kadjar) and Nissan (Qashqai J11) under the Alliance. All meet Euro 6b or Euro 6d-TEMP standards.
Yes. ECU remaps can safely increase output by +15–25 kW on stage 1, as the engine internals are robust. However, tuning increases stress on the HPFP and turbo—only perform with supporting upgrades (e.g., enhanced fuel filtration). Always maintain AdBlue functionality to avoid emissions faults.
Excellent for its class. In a 308 1.6 BlueHDi 120, expect ~4.2 L/100km (67 mpg UK) combined; 3008 165 versions achieve ~4.8 L/100km (59 mpg UK). Real-world figures range 50–65 mpg UK depending on driving style and AdBlue system health.
Yes. The R9M is an interference engine. If the timing chain fails (rare but possible), pistons can contact open valves, causing severe internal damage. However, the chain is designed for life-of-engine service under proper maintenance.
Peugeot specifies ACEA C2/C3 5W-30 low-SAPS synthetic oil. This protects the turbo, DPF, and SCR systems. Change every 20,000 km or annually. Never use non-C2/C3 oils—they can damage after-treatment components.
