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.
Fitted to models such as the 308, 508, and Partner van, the RHR was engineered for refined daily driving and long-distance cruising. Emissions compliance for European markets was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 5 standards.
One documented service concern is potential for EGR valve and cooler clogging, particularly in vehicles subjected to frequent short trips. This issue, referenced in Peugeot Service Information Bulletin 09 03 01, is linked to incomplete DPF regeneration cycles. From 2014, minor EGR system revisions were implemented to improve flow and reduce fouling.
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 VGT turbo provides strong low-to-mid range torque ideal for overtaking and load-carrying but requires adherence to 20,000 km oil change intervals to protect the turbo and maintain DPF efficiency. ACEA C3 (5W-30) oil is critical to minimize ash content and prevent DPF clogging. Vehicles used primarily for short urban trips are prone to EGR and DPF issues; regular highway driving is recommended to ensure complete regeneration cycles. The timing chain is designed as maintenance-free, but oil quality remains paramount for its longevity.
Oil Specs: Requires ACEA C3 specification (Peugeot Owner's Manual). 5W-30 viscosity is standard.
Emissions: Euro 5 certification applies to all 2010–2018 models (VCA Type Approval #VCA/EMS/7654).
Power Ratings: Measured under ECE R85 standards. Output consistent across specified model range (Peugeot TIS Doc. T25678).

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.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Peugeot TIS T25678). The code "RHR" is specific to this 163 PS variant. Visually, it can be identified by its black plastic cam cover with "HDi" and "FAP" (DPF) badging. Critical differentiation from the lower-powered RHY: The RHR has a higher-capacity VGT and a different ECU map. While many ancillary parts are interchangeable, the turbocharger and ECU are specific to the RHR specification.
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.
