Production years 2006–2010 meet Euro 4 standards .
The Peugeot EP3C is a 1,397 cc inline‑four naturally aspirated petrol engineered for compact hatchbacks and coupes (2006-2010). It combines a lightweight aluminium construction with DOHC 16-valve architecture to deliver responsive low-to-mid range performance and good fuel efficiency. Designed to meet Euro 4 standards, it prioritizes cost-effective ownership and serviceability.

The Peugeot EP3C was used across Peugeot's 20x platforms with transverse mounting. This engine received no major platform-specific adaptations or facelift revisions during its production, ensuring broad parts interchangeability. All applications 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 EP3C's primary reliability risk is timing chain tensioner wear, with elevated incidence in vehicles subjected to frequent short trips or poor oil maintenance. Peugeot service data indicates this was a notable service item for high-mileage engines, while its overall design offers good longevity. Neglecting oil changes is the main factor that compromises its durability.

The most common questions about engine codes, what they mean, how to find them and how this database works
Generally, yes. The EP3C is a simple and robust engine. Its main weakness is the timing chain tensioner, which can wear prematurely if oil changes are neglected. With proper maintenance using the correct oil, it can easily reach 200,000 km or more without major issues. Regular servicing is key to its longevity.
The most frequent issues are timing chain tensioner wear (causing noise), VVT solenoid clogging (causing rough idle), ignition coil failure (causing misfires), and oil leaks from the valve cover gasket. These are well-documented in Peugeot service bulletins and are generally straightforward to fix.
The EP3C engine was exclusively used in the Peugeot 207 (hatchback, 2006-2010) and the 207 CC (convertible, 2007-2010). It was badged as the 1.4 VTi or simply 1.4, producing 95 PS. It was not used in any other Peugeot or Citroën models.
Minor gains are possible through ECU remapping, but significant power increases are not feasible. The engine is naturally aspirated and tuned for economy. Remapping might yield 5-10 PS, but it can increase stress on components like the ignition system and may reduce fuel economy and longevity.
Good for its era. In a Peugeot 207, expect around 6.5-7.5 L/100km (38-43 mpg UK) in combined driving. Highway cruising can see figures as low as 5.5 L/100km (51 mpg UK), while city driving might be around 8.0-9.0 L/100km (31-35 mpg UK). Real-world figures depend heavily on driving style.
Yes. The EP3C is an interference engine. If the timing chain were to fail catastrophically (which is rare, but possible if the tensioner fails completely), the pistons would collide with the valves, causing severe internal engine damage. This underscores the importance of addressing tensioner noise promptly.
Peugeot recommends a high-quality 5W-30 or 5W-40 oil meeting ACEA A3/B4 specifications. Using a fully synthetic oil is highly recommended to ensure optimal protection for the timing chain tensioner and VVT system. Oil should be changed every 15,000 km or annually, whichever comes first.
