The Peugeot 9HX (DV6AUTED4) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2006 and 2010. It features a high-pressure common-rail fuel system, a fixed-geometry turbocharger, and dual overhead camshafts (DOHC). In standard tune, it produces 80 kW (109 PS) and 240 Nm of torque, offering a compelling blend of efficiency and urban drivability.
Fitted to compact models like the 207, 308 I, and Partner, the 9HX was engineered for responsive, low-cost motoring with strong low-end pull. Emissions compliance was achieved through exhaust gas recirculation (EGR) and an oxidation catalyst, meeting the stringent Euro 4 standard for its entire production period.
A documented concern involves potential premature failure of the turbocharger's thrust bearing, which can lead to shaft play and oil leakage. This issue, referenced in Peugeot Service Bulletin 09HX01EN01, is linked to oil contamination and extended service intervals. Production updates in late 2008 incorporated a revised turbocharger cartridge to address this.
All production years (2006–2010) meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot 9HX (DV6AUTED4) is a 1,560 cc inline‑four turbo‑diesel engineered for compact hatchbacks and crossovers (2006-2010). It combines high-pressure common-rail injection with a single fixed-geometry turbocharger to deliver strong, linear torque and class-leading fuel economy. Designed to meet Euro 4 standards, it balances everyday practicality with low running costs.

The fixed-geometry turbo provides predictable power delivery but is susceptible to bearing wear if oil changes are neglected. Strict adherence to 20,000 km or annual oil changes using the specified 5W-40 oil is critical. The high compression ratio demands good fuel quality to prevent pre-ignition or injector fouling. Vehicles used for towing should ensure the cooling system is in optimal condition. The revised turbocharger (from late 2008) should be installed if replacing the original unit per Service Bulletin 09HX01EN01.
Oil Specs: Requires Stellantis 9.55535-S2 (5W-40) specification (Stellantis Owner's Manual). ACEA B4 compliant.
Emissions: Euro 4 certification applies to all models (2006-2010) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Stellantis TIS Doc. ENG-DV6A-01).

The Peugeot 9HX (DV6AUTED4) was used across Peugeot's PF2 platform with transverse mounting. This engine received platform-specific adaptations-unique exhaust manifolds for the 308 and revised engine mounts for the Partner-and from late 2008 the updated turbocharger, creating minor part number differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code 'DV6AUTED4' stamped on the front face of the cylinder block, near the alternator (Stellantis TIS ENG-ID-009). The 8th digit of the VIN is '9' for this specific 80kW/109PS variant. Pre-late 2008 models have a turbocharger with part number 7431A2; post-update models use 7431B6. The engine management ECU is a Bosch EDC16 variant. Service parts for the exhaust system (manifold, downpipe) may differ between 207/308 and Partner applications.
The 9HX (DV6AUTED4)'s primary documented concern is turbocharger thrust bearing failure, with elevated incidence in vehicles subjected to infrequent oil changes or poor-quality oil. Peugeot internal data indicates a measurable failure rate within the first 100,000 km for early-build units, while UK DVSA records show no significant correlation with MOT failures. Vehicles used for short trips or towing make strict oil change adherence and using the correct specification critical.
Analysis derived from Stellantis technical bulletins (2007-2010) and UK DVSA failure statistics (2010-2023). Repair procedures should follow manufacturer guidelines.
