The Peugeot 8HS (DV4TED) is a 1,398 cc, inline‑four turbo‑diesel engine produced between 2004 and 2010. It features a cast — iron block, aluminum cylinder head, and common — rail direct injection for precise fuel delivery. In standard form, it delivered 66 kW (90 PS) and 215 Nm of torque, engineered for compact city cars prioritizing fuel efficiency and low emissions.

The Peugeot 8HS (DV4TED) is a 1,398 cc inline‑four turbo‑diesel engineered for supermini applications (2004-2010). It combines a durable cast-iron block with common‑rail direct injection to deliver strong low‑end torque and exceptional fuel economy. Designed to meet Euro 4 standards, it prioritizes urban efficiency and low-cost ownership.

The Peugeot 8HS (DV4TED) was used across PSA Group's supermini platforms with transverse mounting. This engine received platform-specific adaptations-shared ECU mapping with the Citroën C3 and unique engine mounts for the Peugeot 207-with no significant revisions during its production run. 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 8HS (DV4TED)'s primary reliability risk is dual-mass flywheel failure, with elevated incidence in high-mileage vehicles. PSA internal reports noted a significant number of flywheel failures under warranty, while owner feedback frequently cites aggressive driving or clutch abuse as contributing factors. Extended service intervals and poor driving habits make adherence to OEM maintenance schedules critical.
Analysis derived from PSA technical bulletins (2005-2011) and owner-reported failure data (2008-2023). 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 8HS is a simple and generally robust engine, known for its durability and fuel economy. Its main weakness is the dual-mass flywheel, which can fail prematurely with high mileage or aggressive driving. With timely replacement of the flywheel and clutch, and regular oil changes, it can easily reach 200,000 km or more.
The most frequent issues are dual-mass flywheel failure, EGR system clogging, high-pressure fuel pump failure, and glow plug wear. These are well-documented in PSA service bulletins and owner forums, with the flywheel being the most common and costly repair.
This engine was primarily used in the Peugeot 207 (2006-2010) and its platform sibling, the Citroën C3 (2005-2010), both badged as 1.4 HDi 90. It was designed as an economical powerhouse for these popular superminis.
Aftermarket ECU tuning is common on the 8HS-DV4TED 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.
Expect exceptional combined fuel economy of around 55-60 mpg (UK) or 4.5-4.0 L/100km in a Peugeot 207. Real-world figures are outstanding for city driving, often exceeding 65 mpg, while highway cruising can yield up to 70 mpg. It's one of the most economical engines of its era.
Yes. Like most modern engines, the 8HS is an interference design. If the timing chain were to fail, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very robust and rarely fails if maintained.
Peugeot specifies oil meeting the PSA B71 2290 standard, typically a 5W-40 synthetic. Using the correct specification is vital for protecting the high-pressure fuel pump and ensuring proper lubrication of the turbocharger and timing chain.
