The Peugeot RHW (DW10ATED4) is a 1,997 cc, inline‑four turbocharged diesel engine produced between 2010 and 2018. It features double overhead camshafts (DOHC), 16 valves, and a high — pressure common — rail fuel system with a fixed — geometry turbocharger. In standard specification, it delivered 110 kW (150 PS) and 370 Nm of torque, offering strong low — end pull for efficient everyday driving.
Fitted to models such as the 308, 508, and Partner, the RHW engine was engineered…
Production years 2010–2018 meet Euro 5 standards .
The Peugeot RHW (DW10ATED4) is a 1,997 cc inline‑four turbocharged diesel engine engineered for compact and mid‑size vehicles (2010-2018). It combines a high-pressure common-rail injection system with a fixed-geometry turbocharger to deliver abundant low-RPM torque and frugal highway cruising. Designed to meet Euro 5 standards, it prioritizes efficiency and emissions compliance over ultimate performance.

The Peugeot RHW (DW10ATED4) was used across Peugeot's PF2/PF3 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 508 and revised ECU mapping for the Partner. 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.
The RHW's primary reliability risk is EGR valve failure due to carbon buildup, with elevated incidence in vehicles used primarily for short urban trips. Peugeot service bulletins document this issue, while general owner reports highlight DPF regeneration problems as a common secondary concern. Adherence to correct driving patterns and oil specification is critical for mitigating these risks.

The most common questions about engine codes, what they mean, how to find them and how this database works
The RHW engine can be reliable with proper maintenance. The key is managing its emissions systems: using the correct ACEA C2 oil to minimize EGR and DPF clogging, and ensuring regular highway driving for DPF regeneration. Addressing EGR valve issues promptly with the revised part is also crucial for longevity.
The most frequent issues are EGR valve failure due to carbon buildup, DPF clogging from short trips, turbocharger wastegate sticking, and injector seal leaks. These are well-documented in Peugeot service bulletins and are common failure points for Euro 5 diesel engines of this era.
This 2.0L HDi 150 PS diesel engine was used in the Peugeot 308 (2010-2018), the Peugeot 508 (2011-2018), and the Peugeot Partner van (2010-2018). It was the standard-output variant of the DW10 engine family for these models during the Euro 5 era, positioned below the 163 PS RHH engine.
Yes, moderate gains are achievable. An ECU remap can yield around 20-30 kW (25-40 PS) and 50-70 Nm more torque. The engine's internals are robust, but tuning increases stress on the turbo, clutch, and emissions systems. Ensure the EGR and DPF are in good condition before proceeding, as tuning can exacerbate existing issues.
Real-world fuel economy is excellent. In a Peugeot 308, expect around 5.0-6.0 L/100km (47-56 mpg UK) in mixed driving. Highway cruising can see figures closer to 4.0-4.5 L/100km (63-71 mpg UK). City driving will be higher, around 6.5-7.5 L/100km (38-43 mpg UK), especially if DPF regeneration is frequent.
Yes. The RHW is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage. While the chain is generally robust, any unusual noise should be investigated promptly.
Peugeot specifies an oil meeting ACEA C2 standards. A 5W-30 viscosity grade is typically recommended. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is crucial for protecting the DPF and EGR system from premature clogging. Using the wrong oil will significantly shorten the life of these components.
