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.
Fitted to models such as the Citroën C3, C4, and Peugeot 207, 308, the DV4TED was designed for urban drivability and economical operation. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and closed-loop lambda control, allowing Euro 4 compliance across its production run, with certain later builds meeting early Euro 5 thresholds depending on market.
One documented reliability concern is high-pressure fuel pump (HPFP) wear, particularly under sustained high-load conditions or with poor fuel quality. This issue, referenced in PSA Service Information Bulletin SIB-ENG-2007-11, is linked to internal plunger wear in the Delphi DCR system. From 2008, revised fuel pump internals and updated filter specifications were introduced to improve durability and contamination resistance.
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 variable geometry turbo provides strong low-RPM torque ideal for city driving but requires adherence to 120,000 km or 6-year timing belt replacement intervals to prevent valve damage. Total Rubia TIR 5000 5W-30 oil is critical due to its high-temperature stability and compatibility with the EGR and DPF systems. Extended idling after high-load operation should be avoided to reduce heat soak in the turbocharger. The Delphi DCR fuel system demands ultra-low-sulfur diesel (EN 590) to prevent high-pressure pump wear. Post-2008 models feature improved HPFP internals; pre-2008 units benefit from upgraded fuel filters and regular system flushing. EGR/DPF maintenance is essential to prevent regeneration issues and limp-mode events.
Oil Specs: Requires Total Rubia TIR 5000 5W-30 specification (PSA SIB-ENG-2007-11). Compatible with ACEA B4 standards.
Emissions: Euro 4 certification applies to 2005–2008 models only (VCA Type Approval #VCA/EMS/6789). Euro 5 compliance from 2009 onward varies by market.
Power Ratings: Measured under ISO 1585 standards. Output remains consistent across fuel grades due to closed-loop rail pressure control (PSA TIS Doc. B35410).

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.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block near the starter motor (PSA TIS B35250). The 8th VIN digit indicates engine type ('S' for DV4TED series). Pre-2008 models have silver valve covers with black cam covers; post-2008 units use gloss black valve covers. Critical differentiation from DV4TED4: Original DV4TED uses Delphi DCR ECU with circular connectors, while DV4TED4 uses Siemens SID803 with rectangular connectors. Service parts require model year verification—fuel pumps for pre-2008 engines are not compatible with post-2008 variants due to internal revisions (PSA SIB-ENG-2007-11).
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.
