The Peugeot 9HC (DV6C) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) design with 16 valves and common rail direct injection, delivering outputs between 82 kW (112 PS) and 100 kW (136 PS) with torque figures of 270–300 Nm. A variable geometry turbocharger (VGT) ensures strong low — end response ideal for urban and highway driving.
Fitted to models such as the 308, 3008, and Partner, the 9HC (DV6C) was…
All production years (2010–2018) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7654).
The Peugeot 9HC (DV6C) is a 1,560 cc inline‑four turbo‑diesel engineered for compact cars and vans (2010-2018). It combines common rail direct injection with a variable geometry turbocharger to deliver strong low-end torque and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with acceptable emissions.

The Peugeot 9HC (DV6C) was used across Peugeot's PF2 and EMP2 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Partner van and revised cooling for the 3008-and was fitted to various trim levels. All adaptations are documented in OEM technical bulletins.
The 9HC (DV6C)'s primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles subjected to poor fuel quality or infrequent servicing. Peugeot internal service data indicates a notable failure rate after 100,000 km in poorly maintained engines, while general owner reports frequently cite the resulting no-start condition. Use of incorrect fuel or extended service intervals accelerates wear, making adherence to fuel quality and the specified 5W-30 oil critical.
Analysis derived from Peugeot technical bulletins (2010-2018) and owner-reported failure data (2015-2023). 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 9HC (DV6C) is generally robust for its size, but its Achilles' heel is the high-pressure fuel pump. With strict adherence to using high-quality diesel fuel and timely oil changes using 5W-30, these engines can easily surpass 200,000 km. Neglecting fuel quality or allowing the DPF to become blocked through short trips is the primary cause of major failures.
The most frequent issues are high-pressure fuel pump failure (causing no-start), EGR valve clogging leading to rough running, DPF blockage from short trips causing limp mode, and turbocharger wastegate actuator faults. These are well-documented in Peugeot service information and are common to many modern diesel engines.
This 1.6L diesel engine was used in a wide range of Peugeot models from the early 2010s, including the 308 (2011-2018), 3008 (2010-2016), and Partner van (2010-2018). It was available in various power outputs from 112 PS to 136 PS across different trim levels.
Yes, moderately. The 9HC (DV6C) responds well to ECU remapping, with stage 1 tunes often yielding +20-30 kW and +50-70 Nm torque safely. The robust internals and capable turbo allow for substantial gains. Ensure the DPF and EGR systems are in perfect health before tuning, as increased soot production can accelerate blockages.
Expect combined fuel economy of approximately 4.5-5.0 L/100km (63-56 mpg UK) in a Peugeot 308. Real-world figures are excellent for highway driving but can be higher in city use, especially if DPF regeneration is frequent. The official figures are quite achievable with gentle driving.
Yes. The 9HC (DV6C) is an interference engine. If the timing chain were to fail (a rare occurrence) or if the cam timing is severely disrupted, piston-to-valve contact is possible, resulting in significant internal engine damage.
Peugeot mandates a 5W-30 synthetic oil meeting their specific 9736.A3 standard (or equivalent ACEA B4). Using the correct viscosity and specification is critical for the longevity of the turbo and fuel system. Change intervals should not exceed 20,000 km or 1 year.
