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-rich performance in SUVs and executive sedans. Emissions compliance was achieved through a diesel particulate filter (DPF) and selective catalytic reduction (SCR) with AdBlue injection, meeting Euro 5 standards for its primary production run.
One documented concern is premature failure of the high-pressure fuel pump, as noted in Peugeot Technical Note 8921. This issue is often linked to fuel contamination or extended service intervals compromising lubrication. Later production runs incorporated revised pump internals to improve durability.
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 variable-geometry turbo provides strong, linear torque ideal for towing and overtaking but requires strict adherence to 20,000 km oil change intervals to protect the turbo and fuel system. Peugeot B71 2290 (5W-30) oil is critical for its low-ash formulation compatible with the DPF. Extended idling or frequent short trips can cause DPF clogging; periodic highway driving is recommended. The Bosch CP4.2 fuel pump is sensitive to fuel quality; use only ultra-low sulfur diesel (EN 590) to prevent premature failure. Revised pump internals were introduced in 2014 (Peugeot Technical Note 8921).
Oil Specs: Requires Peugeot B71 2290 specification (Peugeot Service Manual 8921). Equivalent to ACEA C2/C3 low-SAPS.
Emissions: Euro 5 certification applies to all 2010–2018 models (VCA Type Approval #VCA/EMS/7890). No market-specific variations.
Power Ratings: Measured under ISO 1585 standards. Output is consistent across model applications (Peugeot Group PT-2015).

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.
Locate the engine code stamped on a flat boss on the front face of the cylinder block, near the gearbox flange (Peugeot TIS 8921). The 8th VIN digit typically corresponds to the engine code ('E' for RHE). Visually, it features a black plastic intake manifold and a prominent AdBlue dosing module near the exhaust manifold. Critical differentiation from the earlier DW10ATED: RHE (DW10CTED4) has an SCR system with an AdBlue tank, while DW10ATED uses only a DPF. Service parts for the fuel pump are specific to production date ranges due to the 2014 update (Peugeot Technical Note 8921).
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.
