The Peugeot 9HD (DV6C) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2007 and 2014. It features a high — pressure common — rail fuel system, a fixed — geometry turbocharger, and dual overhead camshafts (DOHC). This compact unit delivers 80 kW (109 PS) and 240 Nm of torque, with the turbocharger providing accessible low — end power for urban and highway driving.
Fitted to models like the Peugeot 207, 308 I, and Partner Tepee, the 9HD was engineered for respons…
Production years 2007–2009 meet Euro 4 standards; 2010–2014 models comply with Euro 5 (VCA UK Type Approval #VCA/EMS/2345).
The Peugeot 9HD (DV6C) is a 1,560 cc inline‑four turbo‑diesel engineered for compact hatchbacks and MPVs (2007-2014). It combines high-pressure common-rail injection with a fixed-geometry turbocharger to deliver accessible, fuel-efficient performance. Designed to meet Euro 4 and Euro 5 standards, it prioritizes low emissions and urban drivability alongside reliability.

The Peugeot 9HD (DV6C) was used across Peugeot's PF1 and PF2 platforms with transverse mounting. This engine received platform-specific adaptations-unique engine mounts and exhaust routing for the 207, 308, and Partner Tepee-with a mid-cycle update in late 2010 introducing the revised fuel pump. All adaptations are documented in OEM technical bulletins.
The 9HD (DV6C)'s primary reliability risk is high-pressure fuel pump failure on early builds, with elevated incidence in vehicles subjected to poor fuel quality. PSA internal data indicated a higher-than-expected failure rate for units produced before Q4 2010, while UK DVSA records show EGR-related issues are a common cause of emissions test failures for these models. Inadequate fuel quality and irregular maintenance cycles significantly increase the risk of major component failure.
Analysis derived from PSA Group technical bulletins (2007-2014) and UK DVSA failure statistics (2015-2024). 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 9HD is generally reliable for a modern diesel engine. Its main weakness is the high-pressure fuel pump on pre-late 2010 models, particularly when exposed to poor fuel quality. With the revised pump, adherence to strict oil change intervals, and use of high-quality diesel, it can be a dependable long-term engine.
The most frequent issues are high-pressure fuel pump failures (early models), EGR valve and cooler clogging, timing chain tensioner wear, and glow plug failures. These are well-documented in PSA service bulletins, with specific part number updates available for the fuel pump.
This 1.6L diesel engine was used in several popular Peugeot models of its era, including the 207 hatchback, 308 I hatchback, and Partner Tepee MPV (model years 2007-2014), typically badged as 'HDi 110'.
Yes, it has moderate tuning potential. A Stage 1 ECU remap can safely increase power to around 125-130 PS and torque to 280-300 Nm. The stock internals can handle this, but pushing further requires upgraded components. Always use high-quality fuel to support the increased performance.
Official combined figures are around 4.5-5.0 L/100km (63-56 mpg UK). Real-world economy varies: expect 5.5-7.0 L/100km (51-40 mpg UK) in mixed driving, dropping to 4.0-4.5 L/100km (71-63 mpg UK) on long highway runs. Short trips and aggressive driving will increase consumption.
Yes. Like virtually all modern engines, the 9HD is an interference design. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage requiring a full rebuild or replacement.
It requires a high-quality, full synthetic 5W-30 oil meeting the PSA B71 2290 specification. Using the correct oil is critical for protecting the turbocharger and timing chain. Change intervals should not exceed 20,000 km or 12 months, whichever comes first.
