The Citroën DV6C is a 1,560 cc, inline — four turbocharged diesel engine produced between 2004 and 2018. Part of PSA's HDi engine family, it features a cast — iron block, aluminium head, and common — rail direct injection. With a peak output of 80 kW (109 PS) and 240 Nm of torque, the DV6C delivers responsive low — end performance ideal for urban and mixed driving.
Fitted to models such as the C3, C4, and Berlingo, the DV6C was engineered for fuel efficiency and low CO₂ emissions, su…
Production years 2004–2009 meet Euro 4 standards; 2010–2015 models comply with Euro 5; select 2016–2018 variants meet Euro 6b depending on market .
The Citroën DV6C is a 1,560 cc inline-four turbocharged diesel engine developed for compact and light commercial vehicles (2004–2018). It combines common-rail injection with a variable-geometry turbocharger to deliver strong low-RPM torque and improved fuel economy. Designed to meet Euro 4 through Euro 6b standards, it balances performance with regulated emissions compliance.

The Citroën DV6C was used across Citroën's B-segment and LCV platforms with transverse mounting and shared architecture with Peugeot. This engine received platform-specific calibrations-torque tuning in the DS3 and revised intake manifolds in the C3-and from 2012 the facelifted C4 adopted the DV6TED4 variant with SCR technology, creating interchange limits. Partnerships enabled Fiat to use a modified version in the Doblò (2010–2015) with different ECU mapping. 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 DV6C offers good fuel economy and drivability, but early models (2004-2009) had reliability concerns, particularly high-pressure fuel pump failures. Later revisions (post-2010) improved pump durability and fuel filtration, so well-maintained examples can exceed 200,000 km. Regular servicing with PSA B71 2310 oil and adherence to 15,000 km intervals greatly enhance longevity.
The most documented issues are high-pressure fuel pump failure, EGR valve clogging, DPF regeneration problems, and turbo actuator wear. These are confirmed in PSA service bulletins and technical reports. Fuel quality, oil maintenance, and driving patterns significantly influence reliability, especially for emissions components.
The DV6C was used in the Citroën C3, C4, and Berlingo from 2004 to 2018. It was also shared with Peugeot (207) and Fiat (Doblò 1.6 Multijet) under different designations. Output is consistently 109 PS across applications. Emissions standards range from Euro 4 to Euro 6b depending on model year and market.
Aftermarket ECU tuning is common on the 9HJ-DV6C 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.
Excellent for its class. In a C3 1.6 HDi 110, combined consumption is ~4.2 L/100km (67 mpg UK). City driving may see 5.0–5.5 L/100km (51–57 mpg), while highway runs can achieve ~3.8 L/100km (74 mpg). Real-world figures depend on driving style, but it remains one of the most efficient diesel engines of its era.
Yes. The DV6C is an interference engine. If the timing belt fails or skips, piston-to-valve contact will occur, resulting in severe internal damage. While belt life is rated to 150,000 km, any abnormal noise from the front cover should be investigated immediately to prevent catastrophic failure.
PSA specifies a 5W-30 synthetic oil meeting PSA B71 2310 (or newer) specification. This oil is critical for turbo bearing lubrication and high-pressure fuel pump protection. Oil changes should be performed every 15,000 km or annually to maintain engine health and prevent sludge or coking.
