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 (VCA UK Type Approval #VCA/EMS/3456).
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.
The 5FS (EP6C)'s primary documented concern is VVT actuator wear, with elevated incidence in vehicles subjected to infrequent oil changes or poor-quality oil. Peugeot internal data indicates a measurable failure rate within the first 120,000 km for units with neglected maintenance, while UK DVSA records show no significant correlation with MOT failures. Vehicles used for predominantly short journeys make strict oil change adherence and using the correct specification critical.
Analysis derived from Stellantis technical bulletins (2011-2018) and UK DVSA failure statistics (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 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.
