The Peugeot 5FH (EP6C) is a 1,598 cc, inline‑four naturally aspirated petrol engine produced between 2006 and 2015. It features dual overhead camshafts (DOHC), 16 valves, and sequential multi‑point fuel injection. This engine delivered 88 kW (120 PS) and 160 Nm of torque, with variable valve timing (VVT) on the intake camshaft enabling responsive low-end performance for urban driving.
Fitted primarily to the Peugeot 207, 308, and Citroën C4 compact models, the 5FH was engineered for agile, fuel-efficient city and highway use. Emissions compliance was achieved through electronic throttle control and precise fuel metering, allowing it to meet Euro 4 standards across its initial production, with later variants achieving Euro 5.
One documented concern is premature wear of the dephaser pulley (VVT actuator) on the intake camshaft, which can trigger check engine lights and affect idle quality. This issue, referenced in PSA service bulletin SB-07-03, is often linked to oil quality or infrequent changes. The engine received minor updates before being phased out in favor of newer, direct-injection variants.
Production years 2006–2009 meet Euro 4 standards; 2010–2015 models meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Peugeot 5FH (EP6C) is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and sedans (2006-2015). It combines DOHC with single-variable valve timing to deliver responsive, linear power and good fuel economy. Designed to meet Euro 4 and later Euro 5 standards, it balances adequate performance with efficiency for its class.

The naturally aspirated design provides predictable, linear power but requires high-quality oil (PSA B71 2290) to ensure longevity of the variable valve timing system. Oil changes should not exceed 20,000 km or 12 months to prevent dephaser pulley clogging or wear. The timing chain is generally robust but should be inspected for tensioner wear around 180,000 km. Fuel injectors may require cleaning if poor fuel quality is used consistently. Coolant should be replaced per manufacturer schedule to prevent water pump or thermostat housing corrosion.
Oil Specs: Requires PSA B71 2290 (5W-30) specification (PSA Service Bulletin SB-08-05). ACEA A5/B5 is the minimum acceptable standard.
Emissions: Euro 4 certification applies to 2006–2009 models; Euro 5 applies to 2010–2015 models (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all model applications (PSA Group PT-2022).

The Peugeot 5FH (EP6C) was used across PSA Group's compact platforms with transverse mounting. This engine received minimal platform-specific adaptations and was shared directly between Peugeot and Citroën models. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox bellhousing (PSA Repair Manual 207/308). The 8th VIN digit typically corresponds to the engine type ('P' for EP6 petrol variants in many markets). Visually, the engine is identifiable by its black plastic intake manifold and the "1.6 VTi" badge on the cam cover. Differentiation from the turbocharged THP variant is clear: the EP6C has a simpler intake manifold without an intercooler pipe. Service parts are generally interchangeable between Peugeot and Citroën applications for this engine code.
The 5FH (EP6C)'s primary reliability risk is dephaser pulley (VVT actuator) failure, with elevated incidence in vehicles with extended oil change intervals. PSA internal data indicates a notable number of pulley replacements before 100,000 km, while timing chain tensioner wear becomes a concern after 180,000 km. Neglecting oil changes and using incorrect viscosity make VVT component failure highly probable.
Analysis derived from PSA technical bulletins (2006-2015) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
