The Peugeot 9HV (DV6TED4B) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2007 and 2015. It features dual overhead camshafts (DOHC), 16 valves, and a high-pressure common-rail fuel system. This engine delivered 82 kW (112 PS) and 270 Nm of torque, with its variable geometry turbocharger (VGT) enabling strong low-rpm pulling power for urban and highway driving.
Fitted primarily to the Peugeot 308, 508, and Citroën C4 models, the 9HV was engineered for refined, efficient cruising with an emphasis on mid-range torque and low emissions. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), allowing it to meet Euro 5 standards across its production run.
One documented reliability concern is premature failure of the high-pressure fuel pump, which can lead to a complete loss of power. This issue, referenced in PSA service bulletin SB-10-04, is often linked to fuel contamination or extended service intervals. The engine received minor updates before being superseded by newer, more efficient variants.
Production years 2007–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9234).
The Peugeot 9HV (DV6TED4B) is a 1,560 cc inline‑four turbo‑diesel engineered for compact and mid-size family cars (2007-2015). It combines a high-pressure common-rail injection system with a variable geometry turbocharger to deliver strong, sustained torque and quiet operation. Designed to meet Euro 5 standards, it balances performance with increasingly stringent emissions requirements.

The variable geometry turbo provides strong, linear torque ideal for highway driving but requires strict adherence to 20,000 km or annual oil change intervals to prevent turbo and EGR system issues. PSA B71 2290 (5W-30) oil is critical for protecting the high-pressure fuel pump and chain-driven timing system. Fuel quality is paramount; contaminated diesel is the primary cause of premature high-pressure pump failure per PSA SB-10-04. The DPF system requires regular highway driving cycles to regenerate effectively. EGR coolers should be inspected for internal leaks around 120,000 km.
Oil Specs: Requires PSA B71 2290 (5W-30) specification (PSA Service Bulletin SB-08-05). ACEA C3 is the minimum acceptable standard.
Emissions: Euro 5 certification applies to all 2007–2015 models (VCA Type Approval #VCA/EMS/9234).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all model applications (PSA Group PT-2024).

The Peugeot 9HV (DV6TED4B) was used across PSA Group's compact and mid-size platforms with transverse mounting. This engine received minimal platform-specific adaptations and was shared directly between Peugeot and Citroën models. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox bellhousing (PSA Repair Manual 308/508). The 8th VIN digit typically corresponds to the engine type ('V' for DV6 diesel variants in many markets). Visually, the engine is identifiable by its black plastic intake manifold and the "1.6 HDi" badge on the cam cover. Differentiation from petrol variants is clear: the DV6TED4B has no spark plugs or ignition coils. Service parts are generally interchangeable between Peugeot 308, 508, and Citroën C4/DS4 applications for this engine code.
The 9HV (DV6TED4B)'s primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel or with extended service intervals. PSA internal data indicates a notable number of pump replacements before 120,000 km, while EGR cooler leaks become a common concern after 150,000 km. Neglecting fuel quality and oil changes make these failures highly probable.
