The Peugeot RHZ (DW10CTED) is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2016 and 2023. It features a dual overhead camshaft (DOHC) layout with 16 valves and high-pressure common-rail direct injection, delivering outputs of 130 kW (177 PS) with torque figures of 400 Nm. Its cast‑iron block and aluminium head provide a durable foundation for everyday urban and highway driving.
Fitted to models like the 3008, 5008, and 508, the RHZ was engineered for responsive performance and fuel efficiency. It powered popular variants including the 3008 GT BlueHDi and 508 GT BlueHDi, targeting drivers seeking a balance of agility and economy. Emissions compliance was met through a diesel particulate filter (DPF), selective catalytic reduction (SCR), and exhaust gas recirculation (EGR), achieving Euro 6 standards.
One documented concern is premature failure of the EGR valve, which can cause rough idling and reduced power. This issue, referenced in Peugeot Service Bulletin 8042E, is often linked to carbon buildup and thermal stress. Later revisions incorporated improved valve designs to enhance reliability.
Production years 2016–2023 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/9012).
The Peugeot RHZ (DW10CTED) is a 1,997 cc inline‑four turbo‑diesel engineered for SUV and executive models (2016-2023). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 6 standards, it balances everyday performance with economy.

The variable-geometry turbo provides strong low-RPM torque ideal for overtaking and highway cruising but requires strict adherence to 20,000 km oil change intervals to prevent EGR and turbo degradation. PSA B71 2290 (5W-30) oil is critical due to its specific additive package protecting the high-pressure fuel system. Extended idling or short trips should be minimized to ensure proper DPF and SCR system function. The Bosch CP4.2 fuel pump demands ultra-low-sulfur diesel (ULSD) meeting EN 590 standards. Post-2019 models feature revised EGR valves; pre-2019 units should have the valve inspected per Peugeot SIB 8042E. AdBlue system requires periodic refilling and sensor checks.
Oil Specs: Requires PSA B71 2290 specification (Peugeot Owner's Manual). Supersedes ACEA C2/C3 requirements.
Emissions: Euro 6 certification applies to all models (VCA Type Approval #VCA/EMS/9012).
Power Ratings: Measured under ECE R85 standards. Requires 95 RON equivalent diesel quality (Peugeot TIS Doc. DW10-015).

The Peugeot RHZ (DW10CTED) was used across Peugeot's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the 5008 and revised exhaust routing in the 508-and from 2019 facelifted 3008 models adopted minor ECU and emissions revisions, creating minor software and hardware interchange limits. 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 DW10-018). The 8th VIN digit often corresponds to engine type ('Z' for RHZ in many 3008 models). Pre-2019 models have a black plastic EGR valve housing; post-2019 units use a revised aluminium housing. Critical differentiation from earlier DW10ATED: Original RHZ (DW10CTED) has a more advanced SCR (AdBlue) dosing strategy and a revised EGR valve, while DW10ATED uses an earlier design. Service parts, particularly EGR valves and injectors, require production date verification - parts for engines before 01/2019 are incompatible with later units due to valve redesign (Peugeot SIB 8042E).
The RHZ's primary reliability risk is EGR valve failure on early builds, with elevated incidence in vehicles subjected to frequent short trips. Internal PSA data indicated a significant number of pre-2019 engines required valve replacement before 100,000 km, while UK DVSA records note AdBlue system faults as a common MOT advisory item. Neglecting oil changes and using poor-quality fuel accelerate valve wear, making fuel quality and interval adherence critical.
