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…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DV4TED4 offers strong fuel economy and durability but is sensitive to driving patterns and maintenance. Pre-2015 models are prone to EGR coking if used for frequent short trips. Later revisions (post-2015) improved EGR cooler design and SCR integration. Well-maintained examples with regular oil changes, quality fuel, and timely DPF regeneration can exceed 180,000 km.
Key issues include EGR valve coking, DPF regeneration failure, high-pressure fuel pump wear, and timing belt neglect. These are documented in PSA service bulletins. AdBlue system faults and NOx sensor degradation are also reported in high-mileage units. Cold-start hesitation may indicate injector wear.
The DV4TED4 was used in the Citroën C3 1.6 BlueHDi 92 (2011–2018), Berlingo 1.6 BlueHDi 92 (2011–2018), and shared with Peugeot Partner and Opel Combo models. All units from 2011–2015 met Euro 5; 2016–2018 models comply with Euro 6c.
Yes. The DV4TED4 responds well to ECU remapping, with stage 1 tunes typically adding +15–20 kW. The turbo and fuel system support moderate increases, but supporting mods (intercooler, exhaust) are recommended. Tuning should preserve DPF and EGR functionality to avoid emissions-related faults.
In a Citroën C3 1.6 BlueHDi 92, combined consumption is ~3.9 L/100km (72 mpg UK). Real-world figures vary: city driving may see 4.8–5.3 L/100km, while highway runs can achieve 3.6 L/100km (78 mpg UK). Driving style and DPF regeneration frequency significantly influence economy.
Yes. The DV4TED4 uses an interference timing belt design. If the belt skips or breaks, pistons can contact open valves, resulting in severe internal engine damage. Replacement every 5 years or 120,000 km is critical to prevent catastrophic failure.
PSA specifies 5W-30 oil meeting PSA B71 2310 standard. This synthetic oil is formulated for turbocharged diesel engines with DPF and SCR systems. Change every 15,000 km or annually to ensure optimal component life and soot management.
