The Citroën 8HY (engine code DV4TED4) is a 1,560 cc, inline-four turbocharged diesel engine produced by PSA Group between 2011 and 2018. It features high-pressure common-rail direct injection, variable geometry turbocharging (VGT), and dual overhead camshafts (DOHC), delivering 68 kW (92 PS) at 3,750 rpm and 230 Nm of torque at 1,750–2,500 rpm. This configuration provides strong low-end pull ideal for urban and light commercial applications.
Fitted to models such as the Citroën C3, Berlingo, and Peugeot Partner, the DV4TED4 was engineered for efficiency and durability in compact and light van segments. Emissions compliance was achieved through exhaust gas recirculation (EGR), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling Euro 5 and later Euro 6c compliance across its production run.
One documented reliability concern is EGR valve coking, highlighted in PSA Service Bulletin SIB-ENG-2014-05. This issue arises from carbon and oil deposit accumulation due to short-trip driving and delayed maintenance, leading to restricted airflow and regeneration faults. Later production units incorporated revised EGR cooler designs and updated ECU calibration to improve soot management.
Production years 2011–2015 meet Euro 5 standards; 2016–2018 models comply with Euro 6c depending on market (VCA UK Type Approval #VCA/EMS/5685).
The Citroën 8HY (DV4TED4) is a 1,560 cc inline-four turbo-diesel engine engineered for compact and light commercial vehicles (2011–2018). It combines common-rail injection with a variable geometry turbocharger to deliver responsive low-RPM torque and improved fuel economy. Designed to meet Euro 5 and Euro 6c standards, it balances efficiency with regulated emissions compliance.

The VGT turbo provides strong low-RPM torque ideal for stop-start driving but requires strict adherence to 15,000 km oil change intervals to prevent turbo bearing and fuel pump wear. PSA B71 2310 (5W-30) oil is critical due to its soot-handling and thermal stability properties. Extended short-trip cycles increase DPF regeneration frequency and EGR coking. The Bosch CRS 2-16 HPFP demands ultra-low-sulfur diesel (EN 590) to prevent injector and pump wear. Timing belt replacement every 5 years or 120,000 km is essential due to interference design. SCR system requires periodic AdBlue refills and NOx sensor calibration.
Oil Specs: Requires PSA B71 2310 specification (PSA SIB-ENG-2014-05). Compatible with ACEA C3 but not a substitute.
Emissions: Euro 5 certification applies to 2011–2015 models (VCA Type Approval #VCA/EMS/5685). Euro 6c compliance confirmed for 2016–2018 units in UK markets.
Power Ratings: Measured under ECE R85 standards. 68 kW output optimized for urban efficiency (PSA TIS Doc. P22006).

The Citroën 8HY (DV4TED4) was used across Citroën's PF1/PF2 platforms with transverse mounting and shared with Peugeot for compact and light commercial applications. This engine received platform-specific calibrations—higher EGR flow in the Berlingo and SCR integration in the C3—and from 2016 the facelifted C3 adopted the Euro 6c-compliant DV4TED4 variant with revised NOx sensors, creating interchange limits. 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 transmission bellhousing (PSA TIS P21893). The 8th VIN digit indicates engine family ('K' for DV4 series). Pre-2014 models have silver valve covers with black turbo inlet; post-2014 units use black valve covers. Critical differentiation from DV6ATED4: DV4TED4 has smaller displacement and lower output. Service parts require build date verification—timing belts before 06/2014 are incompatible with later SCR-equipped variants due to revised tensioner routing (PSA SIB-ENG-2014-05).
The DV4TED4's primary reliability risk is EGR valve coking, with elevated incidence in vehicles used for short urban journeys. Internal PSA field reports from 2015 indicated a significant number of pre-2015 units required EGR cleaning or replacement before 90,000 km, while UK DVSA data links a notable share of emissions-related MOT failures to DPF saturation in high-mileage examples. Short-trip cycles and poor fuel quality increase particulate and thermal stress, making maintenance interval adherence and fuel specification critical.
