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 compact, fuel-efficient mobility with low running costs. Emissions compliance was achieved through precise electronic throttle control and a three-way catalytic converter, meeting the Euro 5 standard throughout its production run.
A documented concern involves potential wear of the variable valve timing (VVT) actuator's internal components, which can lead to rattling noises and reduced performance. This issue, referenced in Peugeot Service Bulletin 15CZ02EN01, is linked to oil quality and viscosity degradation over extended service intervals. No major production updates were issued, but strict adherence to oil specifications is advised.
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 naturally aspirated design offers predictable, linear power delivery but requires strict adherence to 20,000 km or annual oil changes using the specified 5W-30 oil to protect the VVT actuator and timing chain. The high compression ratio demands 95 RON (premium unleaded) fuel for optimal performance and to prevent knocking. Vehicles subjected to frequent short trips should have the oil level checked regularly, as the engine may consume small amounts of oil between changes. The VVT actuator is sensitive to oil degradation; using non-approved oil can accelerate wear.
Oil Specs: Requires Stellantis 9.55535-S2 (5W-30) specification (Stellantis Owner's Manual). ACEA A5/B5 compliant.
Emissions: Euro 5 certification applies to all models (2010-2018) (VCA Type Approval #VCA/EMS/3456).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Stellantis TIS Doc. ENG-EP6-01).

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.
Locate the engine code 'EP6C' stamped on the front face of the cylinder block, near the oil filter (Stellantis TIS ENG-ID-006). The 8th digit of the VIN is 'E' for this specific 88kW/120PS variant. The engine management ECU is a Bosch ME7.4.4 variant. Service parts for the intake system (manifold, throttle body) may differ between 208/2008 and Partner applications. The VVT actuator is integrated into the intake camshaft sprocket.
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.
