The Peugeot RHE (DW10CTED4) is a 1,997 cc, inline‑four turbo‑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 variable — geometry turbocharger. In standard form, it delivered 120 kW (163 PS) and 340 Nm of torque, engineered for strong low — end pull and efficient cruising.
Fitted to models such as the 3008, 5008, and 508, the RHE engine was designed for refined, torque —…
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Peugeot RHE (DW10CTED4) is a 1,997 cc inline‑four turbo‑diesel engineered for SUVs and executive sedans (2010-2018). It combines DOHC 16-valve architecture with a high-pressure common-rail system and variable-geometry turbo to deliver strong, responsive torque. Designed to meet Euro 5 standards, it balances performance with emissions control.

The Peugeot RHE (DW10CTED4) was used across Peugeot's PF2/PF3 platforms with transverse mounting. This engine received minor ECU mapping adaptations for different vehicle weights and drivetrains but no major facelift revisions affected core compatibility. All adaptations are documented in OEM technical bulletins.
The RHE's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles subjected to poor fuel quality or neglected maintenance. Peugeot internal service data indicated a measurable rate of pump replacement, particularly in pre-2014 engines. Adherence to correct oil and fuel specifications is the primary mitigation factor.
Analysis derived from Peugeot technical bulletins (2011-2017) and UK DVSA failure statistics (2015-2023). 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 RHE is a powerful and refined engine, but its long-term reliability hinges on meticulous maintenance. The high-pressure fuel pump is its Achilles' heel, especially in early models. Using the correct 5W-30 oil, premium diesel, and adhering to service intervals are non-negotiable for longevity. With proper care, it can exceed 200,000 km.
The most frequent and critical issue is high-pressure fuel pump failure. Other common problems include AdBlue system faults (crystallization, pump failure), EGR valve/cooler clogging from carbon buildup, and turbocharger actuator failures. These are well-documented in Peugeot service bulletins.
The RHE engine was primarily used in the Peugeot 3008 (2010-2016), 5008 (2010-2016), and 508 (2011-2018). It was also shared with Citroën, appearing in the C5 Aircross (2017-2018) as the 2.0 BlueHDi 160. It's a transverse-mounted engine for front-wheel-drive platforms.
Yes, it responds well to tuning. An ECU remap can safely increase power by 20-30 kW and torque by 50-70 Nm, as the engine and turbo have robust internals. However, increased stress can exacerbate existing weaknesses like the fuel pump, so supporting modifications and even more diligent maintenance are recommended.
Fuel economy is very good for its power output. In a Peugeot 508 2.0 HDi, expect around 6.5 L/100km in combined driving, translating to approximately 52 mpg UK. Real-world figures can vary from 5.5 L/100km on the highway to 8.0 L/100km in heavy city traffic.
Yes. The RHE is an interference engine. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the timing chain is very durable and rarely fails if oil is changed regularly.
Peugeot mandates oil meeting their B71 2290 specification, which is a 5W-30 low-SAPS (low ash) synthetic oil. This is critical for protecting the DPF and ensuring proper lubrication of the high-pressure fuel system. Using the wrong oil can lead to DPF blockage and accelerated fuel pump wear.
