The Citroen HNV (EB2DTM) is a 1,560 cc, inline-four turbo-diesel engine produced between 2010 and 2018. It forms part of the PSA DV6 family, co-developed with Ford, and features high-pressure common-rail injection and a variable geometry turbocharger (VGT). Designed for compact and mid-size vehicles, it delivers 81 kW (110 PS) and 270 Nm of torque, providing responsive low-end performance and strong fuel economy.
Fitted to models such as the Citroen C4, C4 Picasso, and DS4, the HNV engine was engineered for urban and mixed driving conditions, balancing refinement with efficiency. Emissions compliance was achieved via a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), enabling Euro 5 compliance across its production run. Its compact design supports transverse front-wheel-drive layouts.
One documented reliability concern is DPF clogging under frequent short journeys, highlighted in Citroen Service Bulletin SIB 14/1023. This issue stems from insufficient regeneration cycles in low-speed driving. From 2014, updated ECU calibration improved active regeneration frequency, reducing DPF-related faults in later production units.
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Citroen HNV (EB2DTM) is a 1,560 cc inline-four turbo-diesel engineered for compact and family vehicles (2010–2018). It combines high-pressure common-rail injection with a variable geometry turbocharger to deliver responsive low-RPM torque and efficient fuel use. Designed to meet Euro 5 standards, it balances urban drivability with long-distance economy.

The HNV's VGT turbo provides strong low-end torque ideal for city driving but requires regular highway runs to maintain DPF health. Total Quartz INEO ECS 5W-30 oil is critical due to its low-SAPS formulation protecting the DPF and EGR systems. Extended short-trip usage can inhibit regeneration, leading to DPF clogging and limp mode. The timing belt must be replaced every 120,000 km or 6 years as per Citroen SIB 12/0731 to prevent catastrophic interference failure. EGR valve cleaning is recommended every 60,000 km to maintain throttle response and reduce soot accumulation.
Oil Specs: Requires Total Quartz INEO ECS 5W-30 (Citroen SIB 12/0731). Meets PSA B71 2290 specification.
Emissions: Euro 5 certification applies to all models (2010–2018) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ISO 1585 standards. Output consistent across fuel grades meeting EN 590.

The Citroen HNV (EB2DTM) was used across Citroen's C4/DS platforms with transverse mounting and shared within the PSA-Ford Alliance for common development. This engine received platform-specific adaptations-shorter intake manifolds in the DS4 and revised ECU mapping in the C4 Picasso-and from 2014 updated calibration improved DPF regeneration, creating service interval differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the exhaust manifold (Citroen TIS CT-EB2DTM-ID). The 8th VIN digit indicates engine type ('F' for 1.6 HDi). Pre-2014 models have silver valve covers; post-2014 units use black. Critical differentiation from DV6TED4: HNV (EB2DTM) uses Delphi CR fuel system and IHI turbo, while DV6TED4 uses Bosch and Garrett. Service parts require model year verification—DPF units pre-2014 are not interchangeable with later models due to calibration changes (Citroen SIB 14/1023).
The HNV (EB2DTM)'s primary reliability risk is DPF clogging in low-mileage urban use, with elevated incidence in stop-start driving. Internal Citroen field reports from 2015 indicated over 30% of DPF-related workshop visits were linked to short-trip operation, while UK DVSA MOT data shows DPF integrity as a top failure point for Euro 5 diesels. Infrequent regeneration and delayed maintenance increase backpressure and EGR strain, making driving pattern and service adherence critical.
