Production years 2006–2010 meet Euro 4 standards .
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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
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.
Aftermarket ECU tuning is common on the 9HL-DV6C platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
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.
