The Peugeot 9HL (DV6C) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2006 and 2010. It features a DOHC 16‑valve design with a variable geometry turbocharger (VGT) and high‑pressure common rail direct injection. Output ranges from 80 kW (109 PS) to 92 kW (125 PS), delivering peak torque of 240–270 Nm for responsive urban and highway driving.
Fitted primarily to the Peugeot 308 and 407, the 9HL was engineered for compact and mid-size car efficiency with strong low-end pulling power. Emissions compliance for its production period was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting Euro 4 standards.
One documented concern is premature failure of the high-pressure fuel pump, which can lead to sudden engine cut-outs. This issue, referenced in Peugeot Service Bulletin 10BZ02, is often attributed to fuel lubricity or contamination. Later revisions incorporated modified pump internals to improve durability.
Production years 2006–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/6789).
The Peugeot 9HL (DV6C) is a 1,560 cc inline‑four turbo‑diesel engineered for compact and mid-size models (2006-2010). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong, linear torque and efficient cruising. Designed to meet Euro 4 standards, it balances everyday performance with acceptable emissions for its era.

The VGT turbo provides smooth, lag-free power delivery suited to highway driving but demands strict adherence to 20,000 km oil change intervals using PSA B71 2290 specification to protect the turbo and fuel system. Ultra-low-sulfur diesel (EN 590) is mandatory to prevent high-pressure pump failure. The DPF system requires regular highway driving for passive regeneration; frequent short trips can lead to clogging and costly forced regenerations. The timing chain is generally robust but should be inspected if unusual noise is present. Fuel pump issues were prevalent in early builds; post-2008 units feature revised components per PSA SIB 10BZ02.
Oil Specs: Requires PSA B71 2290 (ACEA C3 equivalent) specification (PSA Owner's Manual).
Emissions: Euro 4 certification applies to all 2006-2010 models (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under ECE R85 standards. Output varies by model application (PSA Group PT-2010).

The Peugeot 9HL (DV6C) was used across Peugeot's PF2 and PF3 platforms with transverse and longitudinal mounting respectively. This engine received no significant platform-specific adaptations or facelift revisions during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the gearbox bellhousing (PSA Repair Manual 9HL). The 8th digit of the VIN is 'L' for the 9HL engine. Visually, it features a black plastic rocker cover with "1.6 HDi" branding and a Garrett turbocharger on the exhaust manifold. Critical differentiation from the later 1.6 HDi 120 (DV6ATED4): The 9HL uses a Siemens VDO ECU with a specific connector, while the 120 PS variant uses a Bosch ECU. Fuel pump part numbers differ significantly; always verify against the engine's build date.
The 9HL (DV6C)'s primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. PSA internal reports indicated a notable failure rate before 150,000 km in early production batches, while owner feedback frequently cites sudden engine cut-outs. Extended periods of low-load driving and infrequent oil changes accelerate pump wear, making fuel quality and maintenance adherence critical.
Analysis derived from PSA technical bulletins (2007-2011) and owner-reported failure data (2010-2023). Repair procedures should follow manufacturer guidelines.
