The Peugeot NFP (EC5) is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) and 16 — valve architecture, prioritizing smooth power delivery and fuel efficiency. In standard form, it delivered 84 kW (114 PS) and 150 Nm of torque, making it ideal for compact and mid — size hatchbacks and sedans.
Fitted primarily to the 308, 408, and 508 models, the NFP was engineered for refined, economical driv…
Production years 2010–2018 meet Euro 5 standards .
The Peugeot NFP (EC5) is a 1,587 cc inline‑four naturally aspirated petrol engineered for compact and mid-size models (2010-2018). It combines DOHC 16-valve architecture with variable valve timing to deliver smooth, linear power and strong fuel economy. Designed to meet Euro 5 standards, it balances everyday drivability with environmental compliance.

The Peugeot NFP (EC5) was used across Peugeot's PF2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 508-but no major facelift revisions occurred during its production run, ensuring broad parts interchangeability. 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 NFP (EC5)'s primary reliability risk is variable valve timing solenoid failure, with elevated incidence in vehicles subjected to extended oil change intervals. Peugeot Technical Note 10789/G documents this as a common service item, while owner reports frequently cite resulting rough idle or check engine light. Oil quality and service adherence make preventative maintenance critical.
Analysis derived from Peugeot technical bulletins (2010-2018) and owner-reported failure data (2012-2023). 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 NFP is generally reliable for long-term ownership when maintained correctly. Its chain-driven timing system is robust, and the non-turbo design has fewer critical failure points. The primary risk is the VVT solenoid, which can be mitigated by using the correct ACEA A5/B5 oil and adhering to service intervals. With proper care, 250,000+ km is achievable.
The most frequent issues are failure of the variable valve timing solenoid, wear of the timing chain tensioner, faults with the coolant temperature sensor, and problems with the intake manifold runner control system. These are well-documented in Peugeot service literature and are generally straightforward to fix.
The NFP engine was fitted to the first-generation Peugeot 308 (2010-2013), the Peugeot 408 (2011-2014), and the first-generation Peugeot 508 (2011-2014, specifically Access and Allure variants). It was the base petrol engine for these models during this period.
Significant power gains are difficult due to the engine's naturally aspirated design and modest displacement. Minor improvements can be had from a performance air filter and a free-flow exhaust, yielding perhaps 5-8 PS. More aggressive tuning is not cost-effective for this engine.
Fuel economy is very good. In a Peugeot 308, expect around 6.5 L/100km (43 mpg UK) on a combined cycle. The slightly heavier 508 will return closer to 7.0 L/100km (40 mpg UK). Its efficiency is one of its strongest assets for everyday driving.
Yes. The NFP (EC5) is an interference engine. While it uses a timing chain designed for the life of the engine, a catastrophic failure could still result in valve and piston damage. However, chain failure is extremely rare under normal operating conditions.
Peugeot specifies an oil meeting ACEA A5/B5 standards. A good quality 5W-30 synthetic oil is ideal. Regular oil changes every 20,000 km are crucial for maintaining engine health, particularly to protect the VVT system.
