The Peugeot 9HP (DV6DTED) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a DOHC 16‑valve design with common rail direct injection and a variable‑geometry turbocharger. In standard applications, it delivers 88 kW (120 PS), engineered for refined efficiency and strong low‑end torque in compact vehicles.
Fitted primarily to the Peugeot 308, 3008, and Citroën C4 Picasso, the 9HP was designed for responsive urban driving and rel…
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9012).
The Peugeot 9HP (DV6DTED) is a 1,560 cc inline‑four turbo‑diesel engineered for compact hatchbacks and MPVs (2010-2018). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with low emissions.

The Peugeot 9HP (DV6DTED) was used across PSA Group's PF2 and EMP2 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts for the 3008 and specific ECU mapping for the C4 Picasso-creating minor interchange considerations. All adaptations are documented in OEM technical bulletins.
The 9HP's primary reliability risk is variable-geometry turbo actuator failure, with elevated incidence in vehicles using poor-quality fuel or with high mileage. Peugeot service data indicates a notable number of replacements under warranty, while owner reports frequently cite loss of power or overboost warnings as precursors. Extended service intervals and contaminated fuel make adherence to the correct oil specification and fuel quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 9HP is generally robust for long-term use if maintained correctly. Its main weakness is the variable-geometry turbo actuator, which can fail prematurely with poor fuel or infrequent servicing. The timing chain is durable. Using the correct 5W-30 low-SAPS oil and high-quality diesel is essential for maximizing longevity and avoiding costly repairs.
The most frequent issues are variable-geometry turbo actuator failures causing boost problems, DPF clogging leading to reduced power, and EGR system clogging causing rough running. High-pressure fuel pump failures are also documented. These are covered in Peugeot service documentation.
The 9HP (DV6DTED) 1.6 HDi 120 engine was used in the Peugeot 308 and 3008 from 2010 to 2018. It was also fitted to the equivalent Citroën C4 Picasso during the same period. It was not used in smaller PSA vehicles like the 208 or larger models like the 508.
Yes, the 9HP responds well to ECU remapping. Stage 1 tunes can safely increase power to around 140-150 PS and torque to 340+ Nm by adjusting boost and fueling. The stock internals are strong enough for these gains. More aggressive tuning requires supporting modifications and is not recommended for daily drivers.
Real-world fuel economy is excellent for a diesel. In a Peugeot 308, expect around 5.5 L/100km (51 mpg UK) in combined driving. Highway cruising can yield 4.5-5.0 L/100km (56-63 mpg UK), while city driving may be 7.0-7.5 L/100km (38-40 mpg UK). Results vary significantly with driving style and vehicle condition.
Yes. The 9HP is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal damage. Fortunately, the front-mounted chain is very reliable if the engine is properly maintained.
Peugeot mandates oil meeting the PSA B71 2312 specification, typically a 5W-30 low-SAPS synthetic. Using the correct oil is vital for protecting the DPF and ensuring proper lubrication of the turbo actuator and timing chain. Always change the oil and filter at the recommended 20,000 km intervals.
