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 e…
Production years 2006–2009 meet Euro 4 standards; 2010–2015 models meet Euro 5 standards .
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 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.
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 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 5FH engine is generally mechanically robust, with a durable chain-driven timing system. Its main weakness is the intake camshaft dephaser pulley, which is sensitive to oil quality and change intervals. With strict adherence to using PSA B71 2290 oil and changing it every 20,000 km, the engine can be very reliable. Neglecting this will almost certainly lead to expensive VVT repairs.
The most frequent issues are intake camshaft dephaser pulley failure, timing chain tensioner wear (after high mileage), coolant leaks from plastic housings, and on some late variants, wear of the HPFP drive lobe. These are well-documented in PSA service bulletins and owner reports.
The 5FH (EP6C) 1.6L petrol engine was used in the Peugeot 207 (2006-2014) and 308 (2007-2015). It was also fitted to the Citroën C4 (2007-2015) and DS3 (2010-2015). It was not used in larger Peugeot models like the 508, which used different engine families.
Yes, but gains are modest. Since it's naturally aspirated, significant power increases require internal modifications. ECU remaps can yield 5-10 kW by optimizing ignition and fuel curves. More substantial gains come from intake/exhaust upgrades and throttle body modifications. It's not a common tuning target due to its focus on efficiency.
Fuel economy is good for a 1.6L NA petrol engine. Expect around 8.5 L/100km (33 mpg UK) in city driving and 5.5 L/100km (51 mpg UK) on the highway. Combined figures are usually around 6.5-7.0 L/100km (40-43 mpg UK), heavily dependent on driving style and vehicle condition.
Yes. The 5FH (EP6C) is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. This underscores the importance of addressing any timing chain rattle immediately.
Peugeot mandates the use of oil meeting the PSA B71 2290 specification, typically a 5W-30 synthetic. Using the correct oil is absolutely critical for the longevity of the variable valve timing dephaser pulley. ACEA A5/B5 is the minimum acceptable industry standard if the PSA-specific oil is unavailable.
