The Peugeot 5FS (EP6C) is a 1,598 cc, inline‑four naturally aspirated petrol engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) valvetrain with variable valve timing (VVT) on the intake cam, delivering a balance of efficiency and responsiveness. In standard tune, it produces 88 kW (120 PS) and 160 Nm of torque, suitable for light, agile urban and highway driving.
Fitted to models like the 208 I, 2008 I, and Partner, the 5FS was engineered for c…
All production years (2010–2018) meet Euro 5 standards .
The Peugeot 5FS (EP6C) is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and crossovers (2010-2018). It combines a DOHC valvetrain with intake-side variable valve timing to deliver smooth, linear power and good fuel economy. Designed to meet Euro 5 standards, it prioritizes reliability and low-cost ownership.

The Peugeot 5FS (EP6C) was used across Peugeot's PF1 platform with transverse mounting. This engine received platform-specific adaptations-unique intake manifolds for the 2008 and revised engine mounts for the Partner-creating minor part number differences. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 5FS is generally a simple and reliable engine. Its main known issue is VVT actuator wear, which is preventable with strict adherence to oil changes using the correct 5W-30 specification. With proper maintenance and use of 95 RON fuel, it can easily achieve high mileage without major issues.
The most documented issue is VVT actuator wear causing rattling noises. Other common concerns include timing chain tensioner failure, throttle body carbon buildup, and ignition coil failure. These are covered in official Peugeot service bulletins and are generally straightforward to fix.
This 1.6L petrol engine was used in the first-generation 208 (2012-2018), first-generation 2008 (2013-2018), and the third-phase Partner van/MPV (2010-2018). It was typically found in mid-range trim levels like Active and Allure.
Limited tuning potential exists due to its naturally aspirated design. ECU remapping can yield minor gains (5-10 kW), primarily by optimizing throttle response and fuel maps. Significant power increases would require forced induction (turbo/supercharger), which is complex and not commonly performed on this engine.
Official combined figures are around 5.5-6.0 L/100km (47-51 mpg UK) for a 208 Active. Real-world mixed driving typically yields 6.5-8.0 L/100km (35-43 mpg UK), with careful highway driving potentially achieving under 5.0 L/100km (56+ mpg UK).
Yes. Like virtually all modern engines, the 5FS is an interference design. If the timing chain were to fail or skip teeth, the pistons would collide with the valves, causing catastrophic engine damage. Fortunately, the chain is very durable with proper maintenance.
It requires a specific 5W-30 synthetic oil meeting the Stellantis 9.55535-S2 specification. Using the correct oil is critical for protecting the VVT system and timing chain. Change intervals are typically 20,000 km or annually.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
