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, supporting Citroën’s eco-friendly vehicle strategy. 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 6b.
One documented reliability concern is high-pressure fuel pump (HPFP) failure due to inadequate lubrication from low-sulfur diesel. This issue, highlighted in PSA Service Bulletin SIB 13-TD-012, 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 2004–2009 meet Euro 4 standards; 2010–2015 models comply with Euro 5; select 2016–2018 variants meet Euro 6b depending on market (VCA UK Type Approval #VCA/EMS/6789).
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 variable-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 13-TD-012, 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 13-TD-012). Supersedes ACEA C3 and B5 standards.
Emissions: Euro 4 applies to 2004–2009 models; Euro 5 (2010–2015); Euro 6b for select 2016+ models (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under ECE R85 standards. Output consistent across fuel grades meeting EN 590 (PSA TIS Doc. B14230).

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.
Locate the engine code stamped on the front lower engine block near the transmission bellhousing (PSA TIS B14230). The 8th VIN digit indicates engine type ('K' for DV6C variants). Pre-2010 models have a black plastic cam cover with 'HDi' badge; post-2010 units use a plain cover. Critical differentiation from DV6TED4: Original DV6C uses Bosch EDC17C54 ECU with grey connector; DV6TED4 uses EDC17CP54 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 13-TD-012).
The DV6C'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.
