The Peugeot RHR (DW10BTED4) is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a cast iron block, aluminium cylinder head, and dual overhead camshafts (DOHC) with 16 valves. This unit, equipped with a variable geometry turbocharger (VGT) and high — pressure common rail injection, delivered 120 kW (163 PS) and 340 Nm of torque, balancing efficiency with strong mid — range pull.

Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7654).
The Peugeot RHR (DW10BTED4) is a 1,997 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2010-2018). It combines high-pressure common-rail injection with a variable-geometry turbocharger to deliver strong, accessible torque and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The Peugeot RHR (DW10BTED4) was used across Peugeot's 30x/50x platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Partner van variant-and shared its core DW10 architecture with the Citroën DW10BTED4 engine, creating broad parts compatibility. All adaptations are documented in OEM technical bulletins.
The RHR's primary reliability consideration is its dependence on complete DPF regeneration cycles and a clean EGR system. Peugeot service documentation highlights EGR valve clogging as a common cause of drivability issues in urban-driven vehicles, while adherence to oil change intervals is critical for DPF and turbo longevity. Frequent short trips without highway driving significantly increase the risk of emissions system faults.

The most common questions about engine codes, what they mean, how to find them and how this database works
The RHR can be very reliable long-term if driven appropriately and maintained correctly. The critical factors are using the correct ACEA C3 oil, changing it every 20,000 km, and ensuring the DPF regenerates regularly through highway driving. Addressing EGR issues promptly is key to avoiding more expensive DPF problems.
The most common issues are EGR valve and cooler clogging, DPF clogging due to incomplete regeneration, turbocharger actuator failure, and leaking fuel injector seals. These are well-documented in Peugeot service information and are typical of modern Euro 5 diesel engines.
The RHR engine was used in the Peugeot 308 (2010-2018), 508 (2011-2018), and Partner van (2010-2018) in their 2.0 HDi 163 trims. It was also fitted to the Citroën C4 Picasso (2010-2013) and other PSA Group vehicles sharing the DW10 platform.
Yes, the RHR responds well to tuning. A stage 1 ECU remap can safely increase power to around 147 kW (200 PS) and torque to 400 Nm. More advanced tuning involves a larger intercooler and upgraded turbo. The bottom end is robust, but ensure the DPF and EGR systems are in good health before tuning.
Fuel economy is excellent for its performance. In a Peugeot 308 2.0 HDi, expect around 6.5 L/100km in the city and 4.5 L/100km on the highway, translating to roughly 52 mpg UK combined. Actual figures depend heavily on driving style and ensuring the DPF regenerates properly.
Yes. The RHR is an interference engine. If the timing chain were to fail (though it is designed to be maintenance-free), the pistons would collide with the open valves, causing significant internal engine damage. This underscores the importance of using the correct oil to ensure chain longevity.
Peugeot mandates an oil meeting the ACEA C3 specification. A 5W-30 viscosity is recommended. Using a high-quality, low-ash, fully synthetic oil that meets this spec is crucial for protecting the DPF and ensuring engine longevity.
