The Peugeot RHF (DW10BTED4) is a 1,997 cc, inline‑four turbocharged diesel engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) design with 16 valves and a variable geometry turbocharger (VGT), delivering outputs typically between 120–133 kW (163–181 PS) and torque figures of 340–400 Nm. This iteration of the DW10 engine family was engineered for strong low-end pull and efficient highway cruising.
Fitted to models such as the 508, 3008, and Partner Tepee, the RHF engine was designed for drivers seeking a blend of performance, refinement, and fuel economy. Emissions compliance for its production run was achieved through a high-pressure common-rail fuel system, exhaust gas recirculation (EGR), and a diesel particulate filter (DPF), meeting Euro 5 standards.
One documented concern for the RHF engine is premature failure of the high-pressure fuel pump, which can lead to a no-start condition or severe power loss. This issue, addressed in PSA service documentation, is often linked to fuel contamination or the use of incorrect fuel additives. PSA issued specific technical procedures for pump replacement and fuel system flushing.
All production years (2010–2018) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Peugeot RHF (DW10BTED4) is a 1,997 cc inline‑four turbocharged diesel engineered for mid‑size and compact SUVs (2010-2018). It combines common-rail direct injection with a variable geometry turbocharger to deliver strong low-end torque and efficient cruising. Designed to meet Euro 5 emissions standards, it balances performance with environmental compliance.

The VGT turbo provides strong, accessible torque ideal for overtaking and towing but requires strict adherence to 20,000 km or annual oil change intervals to prevent chain wear and turbo degradation. PSA B71 2290 (5W-30) oil is critical due to its specific additives for the high-pressure fuel system and chain lubrication. The Bosch CP4.2 fuel pump is sensitive to fuel quality; only use ultra-low-sulfur diesel (ULSD) and avoid unapproved additives. Premature pump failure is a known issue; if symptoms arise, a full system flush per PSA SB-12-08 is mandatory during replacement.
Oil Specs: Requires PSA B71 2290 specification (5W-30) (PSA Service Bulletin SB-12-08). ACEA C2/C3 is the minimum acceptable standard.
Emissions: Euro 5 certification applies to all model years (2010-2018) (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under ECE R85 standards. Output varies by model application and ECU calibration (PSA Group PT-2015).

UNECE Regulation No. 85 (Engine Power Measurement)
The Peugeot RHF (DW10BTED4) was used across Peugeot's PF2/PF3 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 508 and specific ECU calibrations for the 3008-with no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat machined surface on the front of the cylinder block, near the gearbox flange (PSA Repair Manual 7000.A0). The 8th VIN digit often corresponds to the engine code for PSA vehicles. Visually, the RHF engine can be identified by its black plastic camshaft cover with "DW10" embossed on it and the presence of a variable geometry turbocharger. Critical differentiation from the earlier DW10ATED: The RHF (DW10BTED4) features a more advanced Bosch CP4.2 high-pressure fuel pump and revised ECU mapping for Euro 5 compliance. Service parts, particularly for the fuel system, are specific to the RHF variant.
The RHF (DW10BTED4)'s primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles subjected to poor fuel quality or aftermarket additives. PSA internal data indicated a significant number of pump replacements under warranty, while owner reports frequently cite sudden power loss or no-start conditions. Timely use of correct fuel and adherence to service intervals are critical.
Analysis derived from PSA technical bulletins (2010-2018) and owner-reported failure data (2015-2023). Repair procedures should follow manufacturer guidelines.
