The Citroën DW10BTED4 is a 1,997 cc, inline — four turbo — diesel engine produced between 2008 and 2015. It forms part of the PSA DW10 family, widely used across B — and C — segment vehicles, delivering 109 kW (148 PS) and 340 Nm of torque. Featuring common — rail direct injection (up to 1,600 bar), variable geometry turbocharging (VGT), and DOHC valvetrain, it was engineered for responsive mid — range performance and improved fuel economy over earlier DW10 variants.

The Citroën DW10BTED4 is a 1,997 cc inline-four turbo-diesel engineered for medium-duty passenger and light commercial applications (2008–2015). It combines common-rail direct injection with variable geometry turbocharging and SCR-AdBlue technology to deliver responsive torque and reduced NOx emissions. Designed to meet Euro 5 standards, it balances real-world efficiency with regulatory compliance.

The Citroën DW10BTED4 was used across Citroën's Berlingo, Jumpy, and C-segment platforms with transverse mounting and shared with Peugeot and Fiat Professional under platform partnerships. This engine received application-specific tuning—higher idle settings in Relay van variants and revised EGR flow in C4 Picasso—and from 2012 the updated C5 facelift adopted a recalibrated fuel map, creating interchange limits. Partnerships enabled Fiat Scudo and Opel Vivaro to use the same engine architecture. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DW10BTED4 is generally robust when maintained properly, but known risks include HPFP failure and EGR/DPF clogging. Engines with consistent servicing, use of quality fuel, and regular highway driving can exceed 300,000 km. Avoid prolonged low-fuel operation and adhere to the 150,000 km timing belt interval to maximize longevity.
Key issues include high-pressure fuel pump failure due to low fuel levels, EGR and DPF clogging from urban driving, AdBlue system faults, and timing belt degradation. These are documented in PSA service bulletins and field reports. Regular maintenance and proper driving habits significantly reduce failure risk.
The DW10BTED4 was used in the Citroën C4 Picasso (2008–2013), C5 (2008–2015), and Jumpy (2007–2014). It also powered Peugeot Expert and Fiat Scudo under platform sharing. All variants are 2.0 HDi 150 PS with SCR-AdBlue for Euro 5 compliance.
Aftermarket ECU tuning is common on the DW10BTED4 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In combined driving, the DW10BTED4 achieves approximately 5.2–5.8 L/100km (54–49 mpg UK). Highway efficiency is around 4.8 L/100km (59 mpg UK), while city driving may reach 6.5 L/100km (44 mpg UK). Real-world consumption depends on load, driving style, and DPF regeneration frequency.
Yes. The DW10BTED4 is an interference engine. If the timing belt fails or slips, pistons can collide with open valves, causing catastrophic internal damage. Adhering to the 150,000 km or 8-year replacement interval is essential to prevent costly engine repairs.
PSA specifies 5W-30 oil meeting PSA B71 2290 specification. This low-SAPS oil is critical for turbocharger protection and DPF compatibility. Oil changes should be performed every 15,000 km or annually to ensure optimal engine and aftertreatment system longevity.
