The Peugeot 9HY (DV6TED4) is a 1,560 cc inline‑four turbo‑diesel engineered for compact cars (2010-2015). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong low‑end torque and high fuel efficiency. Designed to meet Euro 5 standards, it balances urban drivability with low emissions.

The Peugeot 9HY (DV6TED4) was used across Peugeot's PF2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Partner Tepee-and no significant facelift revisions occurred during its production run, ensuring broad parts compatibility. 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 9HY's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. PSA internal data indicated a notable failure rate before 120,000 km in affected batches, while owner reports frequently cite sudden engine cut-outs. Fuel contamination and infrequent oil changes increase pump stress, making fuel quality and adherence to service schedules critical.
Analysis derived from PSA technical bulletins (2010-2015) 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 9HY offers excellent fuel economy and strong low-end torque but has a known issue with the high-pressure fuel pump. With meticulous maintenance, using high-quality fuel and oil, and adhering to service schedules, it can be reliable. Later examples or those with the updated pump are generally more robust.
The most frequent issues are high-pressure fuel pump failure, EGR system clogging, turbocharger actuator faults, and DPF blockages. These are well-documented in PSA service bulletins and owner forums, often linked to maintenance or fuel quality.
This 1.6 HDi 112 engine was used in the Peugeot 207 (2010-2015), 308 (2010-2015), and Partner Tepee (2010-2015). It was a core engine for Peugeot's compact models during the Euro 5 emissions era.
Yes, ECU remapping is possible and can yield safe power gains of +15-25 kW. The engine's internals are robust. However, increased power puts more strain on the turbo, clutch, and fuel system, so enhanced maintenance and potential hardware upgrades are recommended.
Excellent. In a Peugeot 308, expect combined fuel economy of approximately 4.2 L/100km (67 mpg UK). Highway driving can return ~3.7 L/100km (76 mpg UK), while city driving may consume ~5.2 L/100km (54 mpg UK). Real-world figures vary with driving style and DPF health.
Yes. The 9HY is an interference engine. If the timing chain jumps or fails catastrophically, the pistons can collide with the open valves, causing severe internal damage. While the chain is designed for life, regular inspections for tensioner wear are advised.
Peugeot mandates oil meeting the PSA B71 2290 specification, typically a 5W-40 synthetic. Using the correct oil is vital for protecting the turbocharger, high-pressure fuel pump, and emissions systems. Never use a lower specification oil.
