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 str…
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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 9HL offers strong performance and refinement for its size but has a known weakness with its high-pressure fuel pump, especially in early models. With meticulous maintenance, use of correct oil (PSA B71 2290), and high-quality fuel, it can be reliable. Addressing the fuel pump proactively or ensuring it's the revised version is key to long-term ownership.
The most frequent issues are high-pressure fuel pump failure, EGR system clogging, turbo actuator faults, and DPF regeneration problems. These are well-documented in PSA service bulletins and owner forums. Fuel pump failure is the most critical, often leading to sudden breakdowns.
The 9HL (DV6C) 1.6 HDi engine was fitted to the Peugeot 308 (hatchback, SW) and 407 (sedan) from 2006 to 2010. It was typically badged as the 1.6 HDi 110 or 1.6 HDi 115, depending on the power output and model year.
Yes, the 9HL responds well to ECU remapping. Stage 1 tunes can safely increase power to around 140-150 PS and torque to 300-320 Nm, as the engine and turbo have good headroom. Supporting modifications like a performance intercooler are recommended for higher stages to ensure reliability.
Real-world fuel economy is excellent for its performance. In a Peugeot 308, expect around 5.0-5.5 L/100km (56-51 mpg UK) in mixed driving. Highway cruising can yield 4.0-4.5 L/100km (71-63 mpg UK). City driving and DPF regeneration cycles will increase consumption slightly.
Yes. The 9HL (DV6C) is an interference engine. If the timing chain were to fail (though rare), the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the timing chain is very durable with proper oil changes.
Peugeot mandates the use of oil meeting the PSA B71 2290 specification, typically a 5W-30 synthetic. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is critical for protecting the DPF and catalytic converter from clogging and ensuring proper lubrication of the fuel system components.
