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 respo…
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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 9HX is generally robust when maintained correctly. The main concern is the turbo VGT actuator on early models (2010-2011), which PSA addressed via a service bulletin. Later models are more reliable. Using the correct 5W-30 oil and avoiding constant short trips significantly improves longevity and prevents DPF issues.
The most common issues are turbo VGT actuator failure (early models), DPF clogging from short journeys, EGR valve/clogging, and occasional injector failures. These are well-documented in PSA service bulletins and owner reports, with the actuator being a frequent repair item.
This 1.6L diesel was used in the Peugeot 207 (P08, 2010-2014), 308 (P08, 2011-2015), and Partner Tepee (M59, 2010-2015). It was also shared with Citroën (e.g., C4, DS3) and Opel/Vauxhall (e.g., Meriva, Astra) as part of the PSA Group's engine strategy for compact, efficient vehicles.
Yes, ECU remapping is common and can safely increase power to around 130-140 PS and torque to 300-320 Nm. The engine and turbo have good headroom. However, aggressive tuning can exacerbate VGT actuator and DPF issues, so it's best paired with preventative maintenance and possibly an EGR/DPF delete (where legal).
Excellent for its class. In a 308 1.6 BlueHDi 112, expect around 4.0-4.5 L/100km (71-63 mpg UK) combined. Real-world figures vary: city driving yields ~5.0 L/100km (56 mpg UK), while highway cruising can achieve ~3.5 L/100km (81 mpg UK). DPF or actuator issues will drastically reduce economy.
Yes. Like virtually all modern engines, the 9HX is an interference design. If the timing chain were to fail (though rare), the pistons would collide with the valves, causing catastrophic engine damage. Fortunately, the chain is very durable with proper oil maintenance.
Peugeot mandates a low-SAPS 5W-30 oil meeting the PSA B71 2312 specification. This is crucial for protecting the DPF and turbocharger. Using the wrong oil can lead to rapid DPF clogging and increased engine wear. Change intervals should not exceed 20,000 km or one year.
