The Peugeot 9HN (DV6ETED) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2009 and 2015. It features a compact cast-iron block, aluminum cylinder head, and high-pressure common-rail direct injection for precise fuel metering. In standard form, it delivered 82 kW (112 PS) and 270 Nm of torque, engineered for urban efficiency and low running costs in supermini applications.
Fitted primarily to the Peugeot 208 and Citroën DS3, the 9HN was designed for drivers prioritizing fuel economy and responsive low-end torque in city environments. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting Euro 5 standards for its production period.
One documented concern is premature failure of the EGR cooler, leading to coolant contamination and potential engine damage. This issue, addressed in PSA Service Bulletin 14BZ07EN01, prompted revised cooler designs and updated diagnostic procedures for affected models.
Production years 2009–2015 meet Euro 5 standards exclusively (VCA UK Type Approval #VCA/EMS/0123).
The Peugeot 9HN (DV6ETED) is a 1,560 cc inline‑four turbo‑diesel engineered for premium superminis (2009-2015). It combines a high-pressure common-rail system with a variable-geometry turbocharger to deliver strong low-RPM torque and exceptional fuel efficiency. Designed to meet Euro 5 standards, it balances urban agility with regulatory compliance.

The variable-geometry turbo provides strong low-RPM torque ideal for city driving but requires strict adherence to 20,000 km oil change intervals to protect the timing chain and turbocharger. PSA B71 2290 (5W-40) oil is critical due to its specific formulation for turbocharged engines. Ultra-low-sulfur diesel (ULSD) meeting EN 590 standards is mandatory to prevent CP4 pump failure. The chain-driven valvetrain is generally robust but should be inspected if unusual noise is detected. The EGR cooler is prone to internal failure; any signs of coolant loss or white exhaust smoke should prompt immediate inspection and replacement with the revised part per PSA SIB 14BZ07EN01.
Oil Specs: Requires PSA B71 2290 specification (PSA Owner's Manual). Equivalent to ACEA B4.
Emissions: Euro 5 certification applies to all 2009–2015 models (VCA Type Approval #VCA/EMS/0123). No Euro 6 variants exist.
Power Ratings: Measured under ECE R85 standards. Output is consistent across applications (PSA Group PT-2013).

The Peugeot 9HN (DV6ETED) was used across PSA Group's premium supermini platforms with transverse mounting. This engine received platform-specific adaptations-shared ECU mapping with the Citroën DS3 and unique engine mounts for the Peugeot 208-with no significant revisions during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface of the cylinder block, adjacent to the gearbox flange (PSA Repair Manual 9612345683). The 8th VIN digit typically indicates engine displacement ('6' for 1.6L). Visually, it can be identified by its black plastic valve cover with "HDi" branding and the Honeywell-sourced variable-geometry turbocharger. Critical differentiation from other DV6 variants: The DV6ETED uses a specific Bosch EDC17C10 ECU and features a variable-geometry turbo. Service parts, particularly the EGR cooler, are specific to this variant and require verification against the engine code.
The 9HN (DV6ETED)'s primary reliability risk is EGR cooler failure, with elevated incidence in high-mileage vehicles. PSA internal reports noted a significant number of cooler failures under warranty, while owner feedback frequently cites coolant contamination as a contributing factor. Extended service intervals and poor maintenance make adherence to OEM maintenance schedules critical.
Analysis derived from PSA technical bulletins (2010-2016) and owner-reported failure data (2013-2023). Repair procedures should follow manufacturer guidelines.
