The Peugeot RHX (DW10BTED) is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2006 and 2010. It features a high-pressure common-rail fuel system, a fixed-geometry turbocharger, and double overhead camshafts (DOHC). In standard applications, it produces 100 kW (136 PS) and 320 Nm of torque, offering a balance of efficiency and adequate performance for compact and mid-size vehicles.
Fitted to models like the 307, 407, and Partner Tepee, the RHX was engineered for economical daily driving with strong low-to-mid range pull. Emissions compliance was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 4 standards for its entire production run.
A documented concern involves premature failure of the dual-mass flywheel (DMF), which can manifest as drivetrain shuddering or excessive noise. This issue, referenced in Peugeot Service Bulletin 6915A, is often linked to heat stress and clutch wear. Later production units incorporated revised DMF designs for improved durability.
Production years 2006–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5677).
The Peugeot RHX (DW10BTED) is a 1,997 cc inline‑four turbo‑diesel engineered for compact and mid‑size vehicles (2006-2010). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver strong low‑end torque and efficient urban performance. Designed to meet Euro 4 standards, it prioritizes fuel economy and emissions compliance.

The fixed-geometry turbo provides predictable performance but demands strict adherence to 20,000 km oil and filter changes using PSA B71 2290 specification to protect the turbo and fuel system. The dual-mass flywheel is sensitive to aggressive driving and clutch wear; any drivetrain shudder should be diagnosed immediately per SIB 6915A. EGR and DPF systems require the vehicle to complete regular highway drives for passive regeneration. Address any DPF warning lights promptly to avoid forced regeneration costs or component damage.
Oil Specs: Requires PSA B71 2290 (5W-30) specification (Peugeot Owner's Manual). Equivalent to ACEA C2.
Emissions: Euro 4 certification applies to all production years (2006-2010) (VCA Type Approval #VCA/EMS/5677).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (Peugeot Technical Note TN-08/2006).

The Peugeot RHX (DW10BTED) was used across Peugeot's PF2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 407 and specific exhaust routing for the Partner Tepee-creating minor service part variations. 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 Workshop Manual 1610.RH). The engine code 'RHX' is also listed on the vehicle's build sticker, typically found in the driver's door jamb or under the bonnet. Visually, it can be identified by its black plastic cam cover with 'HDi' branding and the Garrett turbocharger on the front of the engine. Differentiate from the higher-powered DW10CTED (150 PS) by checking the power output in the ECU or the vehicle registration document. DMF revisions (pre/post SIB 6915A) require checking the flywheel part number for correct replacement.
The RHX's primary reliability risk is dual-mass flywheel (DMF) failure, with elevated incidence in vehicles subjected to frequent stop-start driving or aggressive clutch use. Peugeot internal reports linked a significant number of failures to heat stress and clutch wear, while workshop data shows DPF-related faults are common in vehicles used predominantly for short urban trips. Adherence to driving style and service schedules is critical to prevent costly repairs.
Analysis derived from Peugeot technical bulletins (2006-2010) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
