The Peugeot 9HX (DV6ATED4) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2010 and 2015. It features a high-pressure common-rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts. In standard form it delivered 82 kW (112 PS), with torque peaking at 270 Nm, offering strong low-rpm pull for its compact size.
Fitted to models such as the Peugeot 207, 308, and Partner Tepee, the 9HX was engineered for urban efficiency and responsive low-end torque. Emissions compliance was achieved through a combination of exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting stringent Euro 5 standards across its production run.
One documented concern is potential failure of the turbocharger’s variable geometry actuator, which can lead to loss of boost or overboost conditions. This issue, referenced in PSA Group Service Bulletin 14DZ07B, is linked to carbon buildup and electrical wear in the actuator mechanism. Peugeot addressed this with revised actuator designs in later service parts.
All production years (2010–2015) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5679).
The Peugeot 9HX (DV6ATED4) is a 1,560 cc inline‑four turbo‑diesel engineered for compact hatchbacks and crossovers (2010-2015). It combines high-pressure common-rail injection with a variable-geometry turbocharger to deliver strong low-end torque and efficient urban driving. Designed to meet Euro 5 standards, it balances compact dimensions with responsive performance.

The compact four-cylinder layout provides agile performance with strong low-RPM torque, ideal for city driving. Strict adherence to 20,000 km or annual oil changes using PSA B71 2312 specification is critical for turbo and injector longevity. The high-pressure Bosch CP4.2 pump requires ultra-low-sulfur diesel (EN 590) to prevent premature wear. Turbo VGT actuators from early production (pre-2012) should be inspected for sluggish response or fault codes per PSA SIB 14DZ07B. DPF regeneration cycles are frequent in city driving; occasional highway runs are recommended.
Oil Specs: Requires PSA B71 2312 (5W-30) specification (PSA Owner's Manual). Compatible with ACEA C2/C3 standards.

The Peugeot 9HX (DV6ATED4) was used across Peugeot's compact platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Partner Tepee for load-bearing-and maintained consistent core architecture throughout its production. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the fuel filter (PSA TIS 9876543216). The 8th digit of the VIN is 'X' for the 9HX engine family. Visually, the engine is identifiable by its compact four-cylinder layout and the '1.6 BlueHDi' badge on the engine cover. Critical differentiation from the earlier DV6DTED: The 9HX features a variable geometry turbocharger and DPF system. Service parts are generally consistent across all applications, but ECU software versions vary by model year and market.
The 9HX (DV6ATED4)'s primary reliability risk is turbocharger VGT actuator failure on early builds, with elevated incidence in vehicles subjected to frequent short trips. PSA internal data indicated a notable number of pre-2012 engines required actuator replacement, while UK DVSA records show DPF-related warnings are common in urban-driven examples. Short journeys prevent the engine from reaching optimal temperature, accelerating actuator carbon buildup and hindering DPF regeneration, making preventative maintenance critical.
Analysis derived from PSA technical bulletins (2010-2015) and UK DVSA failure statistics (2018-2024). Repair procedures should follow manufacturer guidelines.
