The Citroën DV4C is a 1,398 cc, inline — four naturally aspirated diesel engine produced between 2005 and 2018. Part of PSA's HDi engine family, it features a cast — iron block, aluminium head, and common — rail direct injection. Delivering 50 kW (68 PS) at 4,000 rpm and 160 Nm of torque at 1,750 rpm, the DV4C was engineered for urban efficiency and low running costs.
Fitted to models such as the C2, C3, and Berlingo, the DV4C was designed to offer economical transportation with st…
Production years 2005–2009 meet Euro 4 standards; 2010–2018 models comply with Euro 5 depending on market (VCA UK Type Approval #VCA/EMS/5432).
The Citroën DV4C is a 1,398 cc inline-four naturally aspirated diesel engine developed for compact and light commercial vehicles (2005–2018). It combines common-rail injection with a fixed-geometry turbocharger to deliver strong low-RPM torque and improved fuel economy. Designed to meet Euro 4 and later Euro 5 emissions standards, it balances efficiency with regulated compliance.

The Citroën DV4C 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 C3 and revised intake manifolds in the 1.4 HDi variants-and from 2010 the facelifted C2 adopted the DV4TED4 variant with updated emissions calibration, 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.
The DV4C's primary reliability risk is high-pressure fuel pump failure on early builds, with elevated incidence in vehicles operated on low-quality diesel. Internal PSA quality reports from 2011 noted a significant share of pre-2010 engines requiring HPFP replacement before 120,000 km, while UK DVSA records link a notable portion of emissions-related MOT failures to EGR clogging in stop-start conditions. Infrequent servicing and short-trip driving increase DPF and EGR stress, making adherence to 15,000 km oil changes and periodic regeneration critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DV4C offers good fuel economy and low maintenance costs, but early models (2005-2009) 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 180,000 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 timing belt 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 DV4C was used in the Citroën C2, C3, and Berlingo from 2005 to 2018. It was also shared with Peugeot (107) and Fiat (Doblò 1.4 Multijet) under different designations. Output is consistently 68 PS across applications. Emissions standards range from Euro 4 to Euro 5 depending on model year and market.
Limited tuning potential. The 8-valve SOHC design and fixed-geometry turbo limit airflow and boost response. ECU remapping yields minimal gains. Some enthusiasts upgrade to 16-valve cylinder heads (DV6), but this requires ECU, intake, and exhaust modifications. Best suited for stock reliability rather than performance tuning.
Excellent for its class. In a C3 1.4 HDi 70, combined consumption is ~4.4 L/100km (64 mpg UK). City driving may see 5.0–5.5 L/100km (51–57 mpg), while highway runs can achieve ~3.9 L/100km (72 mpg). Real-world figures depend on driving style, but it remains one of the most efficient small diesel engines of its era.
Yes. The DV4C is an interference engine. If the timing belt fails or skips, piston-to-valve contact will occur, resulting in bent valves and potential engine damage. Given the 120,000 km service interval, proactive replacement is essential to prevent costly repairs, especially in high-mileage examples.
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.
