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 BlueHDi 120 and 1.6 BlueHDi 165—the R9M was engineered for refined urban and motorway driving with strong low‑end torque and CO₂ efficiency. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue, meeting Euro 6b standards from launch.
One documented concern is high-pressure fuel pump (HPFP) failure due to lubrication issues under low-sulfur diesel conditions, highlighted in Peugeot Technical Service Bulletin TSB‑16‑D09. This issue is linked to Bosch CP4.2 pump design sensitivity to fuel contamination or moisture ingress. From 2018, revised pump seals and filtration protocols were introduced across the BlueHDi range to improve reliability.
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 R9M delivers strong low-end torque ideal for urban and highway use but requires strict adherence to 20,000 km or annual oil change intervals using ACEA C2/C3 5W-30 oil to protect the timing chain and turbo bearings. The Bosch CP4.2 high-pressure fuel pump is sensitive to fuel contamination and moisture—only use EN 590 ultra-low-sulfur diesel (ULSD) from reputable stations. AdBlue consumption (~1.5 L/1,000 km) must be monitored; low levels trigger power reduction. EGR and DPF systems demand periodic regeneration cycles—avoid chronic short-trip driving. Revised HPFP seals from 2018 improve reliability; pre-2018 units should follow Peugeot TSB-16-D09 inspection protocols.
Oil Specs: Requires ACEA C2/C3 (5W-30) specification (Peugeot SIB D-16-04). Not compatible with non-low-SAPS oils.
Emissions: Euro 6b certification applies to all 2013–2017 models; 2018–2021 models meet Euro 6d-TEMP (VCA Type Approval #VCA/EMS/8765).
Power Ratings: Measured under ISO 1585 standards. 120 kW output requires correct AdBlue dosing and SCR functionality (Peugeot TIS M56791).

ISO 1585 Road Vehicles – Engine Test Code
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.
Locate the engine code stamped on the front face of the block near the timing cover (Peugeot TIS M56789). The 7th VIN digit indicates engine family ('R' for R9M series). BlueHDi variants feature a blue intake manifold badge and AdBlue tank under the spare wheel well. Critical differentiation from earlier HDi engines: R9M uses a timing chain (not belt) and SCR with AdBlue injection. Service parts require production date verification—fuel pumps before 01/2018 use older CP4.2 seals; post-2018 units require updated kits per Peugeot TSB-16-D09.
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.
