The Peugeot RHD (DW10CB) is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) layout with 16 valves and high-pressure common-rail direct injection, delivering outputs of 120 kW (163 PS) with torque figures of 340 Nm. Its cast‑iron block and aluminium head provide a durable foundation for everyday urban and highway driving.
Fitted to models like the 308, 508, and Partner van, the RHD was engineered for responsive performance and fuel efficiency. It powered popular variants including the 308 GT and 508 Allure, targeting drivers seeking a balance of agility and economy. Emissions compliance was met through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), achieving Euro 5 standards.
One documented concern is premature failure of the high-pressure fuel pump, which can cause hard starting and loss of power. This issue, referenced in Peugeot Service Bulletin 8021C, is often linked to fuel contamination or extended service intervals. Later revisions incorporated improved pump designs to enhance reliability.
Production years 2010–2015 meet Euro 5 standards; 2016–2018 models may have Euro 6 compliance depending on market (VCA UK Type Approval #VCA/EMS/7890).
The Peugeot RHD (DW10CB) is a 1,997 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2010-2018). It combines common‑rail direct injection with a single fixed-geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 5 (and some market‑specific Euro 6) standards, it balances everyday performance with economy.

The fixed-geometry turbo provides predictable power delivery ideal for highway cruising but requires strict adherence to 20,000 km oil change intervals to prevent fuel pump and turbo degradation. PSA B71 2290 (5W-30) oil is critical due to its specific additive package protecting the high-pressure fuel system. Extended idling or short trips should be minimized to ensure proper DPF regeneration. The Bosch CP4.2 fuel pump is sensitive to fuel quality; only ultra-low-sulfur diesel (ULSD) meeting EN 590 standards should be used. Post-2015 models feature revised EGR coolers; pre-2015 units should have the cooler inspected per Peugeot SIB 8021C. Glow plugs are a common wear item and should be inspected regularly.
Oil Specs: Requires PSA B71 2290 specification (Peugeot Owner's Manual). Supersedes ACEA C2/C3 requirements.
Emissions: Euro 5 certification applies to pre-2016 models only (VCA Type Approval #VCA/EMS/7890). Some 2016-2018 models meet Euro 6 depending on market.
Power Ratings: Measured under ECE R85 standards. Requires 95 RON equivalent diesel quality (Peugeot TIS Doc. DW10-005).

The Peugeot RHD (DW10CB) was used across Peugeot's Platform 2 and LCV platforms with transverse mounting. This engine received platform-specific adaptations-reinforced sump in the Partner and revised engine mounts in the 508-and from 2015 facelifted 308 models adopted minor ECU and emissions revisions, creating minor software and hardware interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Peugeot TIS DW10-006). The 8th VIN digit often corresponds to engine type ('H' for RHD in many 308 models). Pre-2015 models have a black plastic EGR cooler; post-2015 units use a revised aluminium cooler. Critical differentiation from later DW10FD: Original RHD (DW10CB) has a single-mass flywheel and a simpler EGR system, while DW10FD uses a dual-mass flywheel and more complex emissions hardware. Service parts, particularly fuel pumps and EGR coolers, require production date verification - parts for engines before 01/2015 are incompatible with later units due to cooler redesign (Peugeot SIB 8021C).
The RHD's primary reliability risk is high-pressure fuel pump failure on early builds, with elevated incidence in vehicles using poor-quality fuel. Internal PSA data indicated a significant number of pre-2015 engines required pump replacement before 120,000 km, while UK DVSA records note EGR cooler failures as a common MOT advisory item. Neglecting oil changes and using non-compliant fuel accelerate pump wear, making fuel quality and interval adherence critical.
