The Peugeot 9HR (DV6C) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2006 and 2014. It features a high-pressure common-rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard European specification, it produced 80 kW (109 PS) and 240 Nm of torque, engineered for compact car efficiency with strong low-end pull.
Fitted primarily to the Peugeot 207, 308, and Citroën C4 platforms, the DV6C was designed for responsive urban driving and fuel-efficient commuting. Emissions compliance for its production period was achieved through an exhaust gas recirculation (EGR) system and a diesel particulate filter (DPF), meeting Euro 5 standards.
A documented service concern involves premature failure of the EGR valve, which can lead to rough running and increased emissions. This issue, referenced in PSA Group Service Bulletin 4488 F, is attributed to carbon buildup causing the valve to stick. Revised valve internals and updated ECU software were introduced to mitigate the problem.
Production years 2006–2014 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5432).
The Peugeot 9HR (DV6C) is a 1,560 cc inline‑four turbo‑diesel engineered for compact hatchbacks and estates (2006-2014). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low-end torque and efficient urban performance. Designed to meet Euro 5 standards, it balances everyday drivability with low emissions.

The VGT turbo provides strong low-RPM torque ideal for city driving but requires strict adherence to 20,000 km or 12-month oil change intervals to prevent turbo and EGR system wear. PSA B71 2296 (5W-30) oil is critical for its specific additive package. Extended idling should be avoided to reduce DPF soot loading. The Bosch fuel system demands ultra-low-sulfur diesel (EN 590) to prevent injector failure. Vehicles experiencing EGR valve issues should have it cleaned or replaced per PSA SIB 4488 F. Regular highway driving is recommended to maintain DPF health.
Oil Specs: Requires PSA B71 2296 (5W-30) specification (PSA Owner's Manual 2007). Equivalent to ACEA C3.
Emissions: Euro 5 certification applies to all 2006–2014 models (VCA Type Approval #VCA/EMS/5432).
Power Ratings: Measured under ECE R85 standards. Output is consistent across specified fuel quality (PSA TIS Doc. DV6-PWR).

The Peugeot 9HR (DV6C) was used across PSA Group's PF2 platform with transverse mounting. This engine received platform-specific adaptations-lighter engine mounts in the 207 and specific ECU mapping for the 308-creating minor service part variations. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the timing cover (PSA TIS DV6-ID). The 8th VIN digit typically indicates engine displacement ('6' for 1.6L). The DV6C is visually identified by its black plastic rocker cover with "1.6 HDi" branding and the Garrett VGT turbocharger. Critical differentiation from the non-VGT DV6: The C variant has a visible VGT actuator arm on the turbo. Service parts, particularly for the EGR and fuel systems, are specific to the DV6C variant and require verification against the engine's build date.
The DV6C's primary reliability risk is EGR valve failure due to carbon buildup, with elevated incidence in high-mileage vehicles operating in stop-start conditions. PSA internal reports from 2012 indicated a significant number of failures before 100,000 km, particularly in urban environments. Short-trip driving and extended oil change intervals are key aggravating factors, making adherence to the maintenance schedule critical.
Analysis derived from PSA technical bulletins (2010-2014) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
