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 strong low-end torque for city driving. Emissions compliance was achieved through exhaust gas recirculation (EGR), diesel particulate filter (DPF), and selective catalytic reduction (SCR) on later variants, meeting Euro 4 standards initially and progressing to Euro 5.
One documented reliability concern is high-pressure fuel pump (HPFP) wear due to inadequate lubrication from low-sulfur diesel. This issue, highlighted in PSA Service Bulletin SIB 14-TD-008, is linked to fuel quality sensitivity. From 2010, revised HPFP calibration and updated fuel filtration were introduced to improve durability across the fleet.
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 fixed-geometry turbo provides strong low-RPM torque ideal for city driving but requires adherence to 15,000 km oil change intervals to prevent EGR and DPF clogging. PSA B71 2310 (5W-30) oil is essential due to its compatibility with the common-rail system and turbo lubrication. Extended idling and short trips increase soot loading, requiring periodic active DPF regeneration. High-pressure fuel pump failures are more likely when using non-EN 590 diesel; fuel quality should be verified. Post-2010 models feature revised HPFP calibration and improved filtration per PSA SIB 14-TD-008, reducing failure incidence. EGR valve cleaning should be performed every 80,000 km to maintain airflow and prevent limp mode.
Oil Specs: Requires PSA B71 2310 (5W-30) specification (PSA SIB 14-TD-008). Supersedes ACEA C3 and B5 standards.
Emissions: Euro 4 applies to 2005–2009 models; Euro 5 compliance for 2010+ models confirmed via VCA Type Approval #VCA/EMS/5432.
Power Ratings: Measured under ECE R85 standards. Output consistent across fuel grades meeting EN 590 (PSA TIS Doc. B13210).

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.
Locate the engine code stamped on the front lower engine block near the transmission bellhousing (PSA TIS B13210). The 8th VIN digit indicates engine type ('J' for DV4C variants). Pre-2010 models have a black plastic cam cover with 'HDi' badge; post-2010 units use a plain cover. Critical differentiation from DV4TED4: Original DV4C uses Bosch EDC16C34 ECU with grey connector; DV4TED4 uses EDC17C54 with black connector. Service parts require build date verification – high-pressure fuel pumps before 05/2010 are incompatible with later models due to revised calibration (PSA SIB 14-TD-008).
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.
