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 r…
Production years 2010–2015 meet Euro 5 standards; 2016–2018 models may have Euro 6 compliance depending on market .
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. 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 RHD is generally robust with modern diesel technology. Its main weakness is the early high-pressure fuel pump, prone to failure before 120,000 km on pre-2015 models. Later revisions and diligent maintenance, especially using correct 5W-30 oil and high-quality fuel, make it a dependable engine for high mileage.
The most frequent issues are high-pressure fuel pump failure (causing hard starting), EGR cooler failure (leading to coolant loss), DPF regeneration problems, and turbocharger actuator faults. These are well-documented in PSA service bulletins and are common wear items for engines of this era.
This 2.0L diesel engine was widely used in the Peugeot 308 (2011-2018), 508 (2011-2018), and Partner van (2010-2018). It also powered Citroën models like the C4 Picasso (2013-2018). It was found in variants like the 308 GT and 508 Allure, primarily meeting Euro 5 emissions standards.
Yes, but gains are modest. ECU remaps can yield +10-20 kW by optimizing fuel and boost maps. More significant power requires hardware like a performance turbo, intercooler, and exhaust. The engine responds well to tuning, but the fuel system is sensitive, so moderate upgrades are recommended.
Excellent for its size. In a Peugeot 308 2.0 BlueHDi, expect ~5.5 L/100km (city) and ~4.0 L/100km (highway), or around 60 mpg UK combined. The lighter 308 is more efficient than the 508. Real-world economy typically ranges from 50-65 mpg UK, depending heavily on driving style and vehicle condition.
Yes. The RHD is an interference engine. If the timing chain jumps or breaks, the pistons will collide with the open valves, causing catastrophic engine damage. This makes maintaining the timing chain in good condition absolutely essential.
Peugeot specifies a 5W-30 synthetic oil meeting the PSA B71 2290 standard. Using the correct oil is vital for protecting the high-pressure fuel system and ensuring proper lubrication. Change intervals should not exceed 20,000 km or 12 months to maintain engine health.
