The Citroën RHF (DW10BTED4) is a 1,997 cc, inline-four, turbocharged diesel engine produced between 2008 and 2018. It is part of the PSA DW engine family, derived from the Ford/PSA joint-venture DLD platform, and engineered for durability and strong low-end torque. Featuring high-pressure common-rail direct injection, variable geometry turbocharging (VGT), and DOHC 16-valve layout, it produces 103 kW (140 PS) at 4,000 rpm and 340 Nm at 2,000 rpm, delivering robust performance ideal for mid-size and commercial applications.
Fitted to models such as the C5, C6, and Jumpy, the DW10BTED4 was engineered for refined driving dynamics and long-distance comfort. Emissions compliance was achieved through exhaust gas recirculation (EGR), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling Euro 5 compliance across its production run. The engine’s longitudinal mounting and robust construction made it suitable for both passenger and light commercial variants.
One documented concern is premature EGR cooler failure, particularly in early production units operating under frequent short-trip conditions. This issue, referenced in PSA Service Information Bulletin SIB-ENG-2013-05, is linked to thermal cycling stress and was addressed through revised coolant flow routing and upgraded EGR valve calibration from 2012 onward.
Production years 2008–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9824).
The Citroën RHF (DW10BTED4) is a 1,997 cc inline-four turbocharged diesel engine engineered for mid-to-large applications (2008–2018). It combines high-pressure common-rail injection with a variable geometry turbocharger to deliver strong low-RPM torque and smooth cruising. Designed to meet Euro 5 standards, it balances performance with acceptable fuel economy and emissions for executive and fleet use.

The VGT turbo provides strong low-RPM torque ideal for highway driving but requires adherence to 15,000 km oil change intervals using PSA-approved 5W-30 to prevent EGR and turbo degradation. Total Rubia TIR 5W-30 oil is critical due to its specific formulation protecting the SCR system and EGR cooler. The Bosch CRS 2-20 fuel system demands ultra-low-sulfur diesel (ULSD) meeting EN 590 standards to prevent high-pressure pump failure. Post-2012 models feature revised EGR coolant routing; pre-2012 units should have the upgrade per PSA SIB-ENG-2013-05. DPF regeneration requires regular longer journeys to prevent clogging. Use of low-quality diesel increases injector and EGR failure risk.
Oil Specs: Requires Total Rubia TIR 5W-30 specification (PSA SIB-ENG-2013-05). Meets ACEA C3 and PSA B71 2290.
Emissions: Euro 5 certification applies to all models (2008–2018) (VCA Type Approval #VCA/EMS/9824).
Power Ratings: Measured under ECE R85 standards. 103 kW output requires EN 590 diesel with proper AdBlue dosing (PSA TIS Doc. DW10BTED4-PERF-01).

The Citroën RHF (DW10BTED4) was used across Citroën's PF3/PF4 platforms with longitudinal mounting and shared with Peugeot and Ford derivatives. This engine received platform-specific adaptations-reinforced mounts in the C6 and revised intake manifolds in the Jumpy-and from 2012 the facelifted C5 adopted updated ECU mapping and SCR calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block, near the timing cover (PSA TIS DW10BTED4-ID-01). The 8th VIN digit indicates engine type ('H' for DW10BTED4). Pre-2012 models have silver cam covers with black plastic intake manifolds; post-2012 units use gloss black cam covers. Critical differentiation from DW10TED4: DW10BTED4 features a Honeywell VGT turbo with electronic actuator and SCR/AdBlue system. Service parts require model-year verification—EGR coolers and DPF units differ pre- and post-2012 due to revised cooling layout (PSA SIB-ENG-2013-05).
The DW10BTED4's primary reliability risk is EGR cooler failure in early production units, with elevated incidence in urban driving cycles. PSA internal quality reports from 2014 indicated a significant number of pre-2012 units required EGR replacement before 150,000 km, while UK DVSA MOT records show increased DPF and SCR failures linked to coolant contamination in neglected engines. Frequent short trips and delayed maintenance amplify thermal stress, making coolant quality and service adherence critical.
