The Citroen DW10UTED4 is a 1,997 cc, inline-four turbo-diesel engine produced between 2008 and 2015. Part of the PSA DW10 family, it delivers balanced performance for mid-size vehicles. Equipped with a dual overhead camshaft (DOHC), high-pressure common-rail injection, and a variable geometry turbocharger, it produces 103 kW (140 PS) with 340 Nm of torque, offering strong low-end pull ideal for motorway cruising and light towing.
Fitted primarily to the Citroën C5 and Peugeot 508, the DW10UTED4 was engineered for driver comfort, refined power delivery, and emissions compliance. Emissions control meets Euro 5 standards via a diesel particulate filter (DPF), exhaust gas recirculation (EGR), and closed-loop lambda feedback, enabling broad European market acceptance. Its robust iron block and compact design support long-term durability under sustained load.
One documented concern is premature high-pressure fuel pump (HPFP) wear observed in certain 2008–2010 production units, highlighted in PSA Technical Bulletin TGB012. This issue is attributed to fuel contamination and inadequate filtration in early fuel system designs. From 2011 onward, an upgraded Bosch CP3 HPFP with revised fuel filter housing was implemented to improve reliability.
Production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9678).
The Citroen DW10UTED4 is a 1,997 cc inline-four turbo-diesel engine engineered for executive sedans and wagons (2008–2015). It combines DOHC 16-valve architecture with common-rail direct injection and a variable geometry turbocharger to deliver responsive low-RPM torque and strong fuel economy. Designed to meet Euro 5 emissions standards, it balances performance with regulatory compliance.

The turbocharged DOHC design provides strong low-RPM torque ideal for highway driving and light load carrying, but demands strict timing belt maintenance to prevent engine damage. SAE 5W-30 ACEA B4 oil is recommended to ensure proper lubrication under varied loads. Cold-start idling should be minimized to reduce wear during warm-up. The Bosch CP3 fuel system requires ultra-low-sulfur diesel (ULSD) meeting EN 590 standards to prevent high-pressure pump seizure. Post-2011 models feature upgraded fuel filtration; pre-2011 engines should be inspected for fuel pump wear per PSA TGB012. The DPF system requires regular highway runs to maintain regeneration cycles and prevent clogging.
Oil Specs: Requires ACEA B4 specification (PSA SIB TGB012). BMW Longlife or VW 502 00 not compatible.
Emissions: Euro 5 certification applies to all DW10UTED4 models (2008–2015) (VCA Type Approval #VCA/EMS/9678).
Power Ratings: Measured under ECE R85 standards. Output consistent across fuel qualities meeting EN 590 (PSA TIS DW1012).

The Citroen DW10UTED4 was used across Citroen's C5 platform with longitudinal mounting and shared with Peugeot under PSA platform commonality. This engine received model-specific tuning-for smoother throttle response in the C5-and from 2011 the updated Bosch CP3 fuel pump with improved filtration, creating interchange limits. Partnerships within the PSA Group allowed Peugeot's 508 to use identical powertrain calibration. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the right-side of the cylinder block near the exhaust manifold (PSA TIS DW1005). The 8th VIN digit indicates engine type ('D' for DW10UTED4 series). Pre-2011 models have a silver cam cover with black intake manifold; post-2011 units use black cam covers. Critical differentiation from DW10ATED4: DW10UTED4 has Bosch EDC16CP34 ECU with rectangular diagnostic connector, while DW10ATED4 uses EDC17CP13 with trapezoidal port. Service parts require production date verification - fuel pumps for engines before 06/2011 are incompatible with later revised units (PSA SIB TGB012).
The DW10UTED4's primary reliability risk is high-pressure fuel pump failure on early builds, with elevated incidence in high-mileage vehicles. PSA internal reports from 2011 noted a significant number of pre-2011 engines requiring HPFP replacement before 150,000 km, while UK DVSA MOT records show DPF-related failures linked to urban driving. Extended stop-start cycles and poor fuel quality increase failure risk, making adherence to maintenance schedules critical.
Analysis derived from PSA technical bulletins (2008-2015) and UK DVSA failure statistics (2010-2018). Repair procedures should follow manufacturer guidelines.
