The Peugeot 9HZ (DV6TED4) is a 1,560 cc inline‑four turbo‑diesel engineered for compact and mid-size models (2010-2015). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong, linear torque and efficient cruising. Designed to meet Euro 5 standards, it balances spirited performance with acceptable emissions for its era.

The Peugeot 9HZ (DV6TED4) was used across Peugeot's PF2 platform with transverse mounting. 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 9HZ (DV6TED4)'s primary reliability risk is timing chain tensioner failure, with elevated incidence in vehicles with modified ECU maps or aggressive driving. PSA internal reports indicated a notable failure rate before 100,000 km in early production batches, while owner feedback frequently cites a distinctive rattle on cold start. Extended periods of high-RPM operation and infrequent oil changes accelerate tensioner wear, making maintenance adherence critical.
Analysis derived from PSA technical bulletins (2012-2016) 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 9HZ offers strong performance and refinement but has a known weakness with its timing chain tensioner, especially in early models. With meticulous maintenance, use of correct oil (PSA B71 2290), and high-quality fuel, it can be reliable. Addressing the tensioner proactively or ensuring it's the revised version is key to long-term ownership. Avoid aggressive ECU tunes without supporting modifications.
The most frequent issues are timing chain tensioner failure, EGR system clogging, turbo actuator faults, and DPF regeneration problems. These are well-documented in PSA service bulletins and owner forums. Tensioner failure is the most critical, as it can lead to total engine destruction.
The 9HZ (DV6TED4) 2.0 HDi 156 engine was fitted to the Peugeot 308, 3008, and 508 from 2010 to 2015. It was the higher-output variant of the 2.0 HDi family, typically badged as the 2.0 HDi 150 or 2.0 HDi 156 depending on the market and model year.
Aftermarket ECU tuning is common on the 9HZ-DV6TED4 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 good for its performance. In a Peugeot 308, expect around 5.5-6.5 L/100km (51-43 mpg UK) in mixed driving. Highway cruising can yield 4.5-5.0 L/100km (63-56 mpg UK). City driving and DPF regeneration cycles will increase consumption.
Yes. The 9HZ (DV6TED4) is an interference engine. If the timing chain were to fail or jump due to tensioner issues, the pistons would collide with the open valves, causing catastrophic internal engine damage. This makes addressing any chain rattle immediately paramount.
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 timing chain system.
