The Peugeot RHK (DW10UTED4) is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a high-pressure common-rail fuel system, a variable geometry turbocharger (VGT), and double overhead camshafts (DOHC). In standard applications, it produces 120 kW (163 PS) and 340 Nm of torque, offering a blend of performance and efficiency for mid-size vehicles.
Fitted to models like the 508 sedan and SW, as well as the 3008 and 5008 SUVs, the RHK was engineered for refined cruising and strong low-end pull. Emissions compliance was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 5 standards for its entire production run.
A documented concern involves the high-pressure fuel pump, which can suffer from premature wear leading to hard starting or power loss. This issue, referenced in Peugeot Service Bulletin 6916A, is often linked to fuel lubricity or contamination. Later production units incorporated revised pump internals for improved durability.
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot RHK (DW10UTED4) is a 1,997 cc inline‑four turbo‑diesel engineered for mid‑size sedans and SUVs (2010-2018). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong low‑end torque and smooth highway performance. Designed to meet Euro 5 standards, it balances power with emissions compliance.

The VGT turbo provides responsive 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 Bosch CP4.2 pump is sensitive to fuel quality; only ultra-low-sulfur diesel (EN 590) should be used to prevent internal wear. EGR and DPF systems require the vehicle to complete regular highway drives for passive regeneration. Address any fuel pressure DTCs immediately, as per SIB 6916A, to avoid catastrophic pump failure and potential injector damage.
Oil Specs: Requires PSA B71 2290 (5W-30) specification (Peugeot Owner's Manual). Equivalent to ACEA C2.
Emissions: Euro 5 certification applies to all production years (2010-2018) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (Peugeot Technical Note TN-09/2010).

The Peugeot RHK (DW10UTED4) was used across Peugeot's PF2 and PF3 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced subframes in the 508 and specific engine mounts for the 3008-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 'RHK' 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 Honeywell turbocharger on the front of the engine. Differentiate from the lower-powered DW10CTED4 (150 PS) by checking the power output in the ECU or the vehicle registration document. Fuel pump revisions (pre/post SIB 6916A) require checking the pump part number for correct replacement.
The RHK's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles using poor-quality fuel or extended service intervals. Peugeot internal reports linked a significant number of failures to fuel lubricity issues, while workshop data shows DPF-related faults are common in vehicles used predominantly for short urban trips. Adherence to fuel quality and service schedules is critical to prevent costly repairs.
Analysis derived from Peugeot technical bulletins (2010-2018) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
