The Citroen 8HS (DV4TED) is a 1,398 cc, inline — four turbocharged diesel engine produced between 2005 and 2013. It features a DOHC 16 — valve configuration with common rail direct injection and a variable geometry turbocharger (VGT), delivering 70 kW (95 PS) at 4,000 rpm and 200 Nm of torque at 1,750 rpm. Part of the PSA DV engine family, the DV4TED was engineered for compact packaging, fuel efficiency, and responsive low — end torque in city and small family vehicles.

Production years 2005–2008 meet Euro 4 standards; 2009–2013 models comply with Euro 5 depending on market (VCA UK Type Approval #VCA/EMS/6789).
The Citroen 8HS (DV4TED) is a 1,398 cc inline-four turbocharged diesel engine engineered for compact and subcompact platforms (2005–2013). It combines common rail direct injection with a variable geometry turbocharger to deliver strong low-RPM torque and efficient urban driving. Designed to meet Euro 4 and Euro 5 emissions standards, it balances economy and drivability for entry-level diesel hatchbacks.

The Citroen 8HS (DV4TED) was used across Citroen's Platform 1 and Platform 2 with transverse mounting and shared extensively with Peugeot under PSA Group harmonisation. This engine received platform-specific adaptations-reinforced engine mounts in the C4 and revised ECU mapping in the Peugeot 207-and from 2008 the updated DV4TED4 variant introduced improved fuel pump durability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The DV4TED's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in long-distance or poorly maintained vehicles. Internal PSA quality reports from 2009 indicated a notable share of pre-2008 engines required HPFP replacement before 100,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to EGR clogging in city-driven vehicles. Poor fuel quality and extended service intervals increase wear risk, making fuel filtration and oil quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DV4TED is generally reliable when properly maintained, but early models (2005–2007) had high-pressure fuel pump concerns. Later revisions (post-2008) improved pump durability, so well-maintained examples can exceed 140,000 km. Regular fuel filter changes and timely timing belt replacement are essential for longevity.
The main issues are high-pressure fuel pump failure (especially pre-2008), timing belt failure due to age, and EGR/DPF clogging from short trips. Other common complaints include turbo actuator sticking and occasional oil leaks. These are documented in PSA service bulletins and technical reports.
This 1.4L diesel engine was used in compact and subcompact Citroen models. It powered the C3 (2005–2013) and C4 (2006–2010). The engine was also shared with Peugeot (207, 308) across the same production window. All variants meet Euro 4 or Euro 5 standards depending on model year.
Yes. The DV4TED responds well to ECU remapping. Stage 1 tunes typically gain +15–25 kW safely, as the stock turbo and internals handle increased boost. Supporting mods like intercooler upgrades and exhausts allow further gains. However, over-tuning without fuel system upgrades risks HPFP failure or DPF overload.
Excellent for its class. In a C3 or 207 (95 PS version), typical consumption is ~5.8 L/100km (city) and ~4.1 L/100km (highway), or about 54 mpg UK combined. Real-world figures depend on driving style. Expect 50–55 mpg (UK) on mixed roads for a healthy DV4TED.
Yes. The DV4TED is an interference engine. If the timing belt fails, pistons can strike open valves, causing severe internal damage. That's why belt replacement every 120,000 km or 6 years is critical—any sign of belt wear or tensioner noise should be addressed immediately.
PSA specifies Total Rubia TIR 5000 5W-30 synthetic oil. Use a high-quality oil suitable for modern diesel engines and change it every 15,000 km (or annually) to protect the EGR, DPF, and fuel system from wear and deposits.
