The Peugeot EP3C is a 1,397 cc, inline‑four naturally aspirated petrol engine produced between 2006 and 2010. It features an aluminium block and head, DOHC valvetrain with 16 valves, and sequential multi‑point fuel injection. Peak output is 70 kW (95 PS) with 136 Nm of torque, engineered for responsive urban driving in compact Peugeot models.
Fitted primarily to the 207 and 207 CC, the EP3C was designed for drivers prioritizing fuel economy and low running costs in city and suburban environments. Emissions compliance for its production era was achieved through a three‑way catalytic converter and electronic engine management, meeting Euro 4 standards.
One documented service concern is premature wear of the timing chain tensioner, which can lead to chain noise or slack. This issue, referenced in Peugeot service documentation, is often linked to oil quality or extended service intervals. The design was carried over to later Prince-family engines with minor revisions.
Production years 2006–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/9876).
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 DOHC 16-valve design provides a smooth and responsive power delivery ideal for city driving but requires strict 15,000 km oil changes with quality semi-synthetic or synthetic oil to protect the chain tensioner and VVT system. The timing chain is designed to last the engine's life but is sensitive to oil degradation; neglect can cause tensioner wear and noise. Pre-ignition knock sensors demand high-quality 95 RON fuel. Coolant should be replaced every 5 years to prevent corrosion.
Oil Specs: Requires ACEA A3/B4 specification oil (Peugeot Owner's Manual 2007). Synthetic oils are recommended for optimal chain tensioner performance.
Emissions: Euro 4 certification applies to all 2006–2010 models (VCA Type Approval #VCA/EMS/9876).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model applications (Peugeot TIS Doc. EP3-001).

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.
Locate the engine code stamped on a flat boss on the front face of the cylinder block, near the exhaust manifold (Peugeot TIS EP3-001). The 8th VIN digit typically corresponds to the engine code ('C' for EP3C). Visual identification: Aluminium block with a black plastic rocker cover and a Siemens fuel rail mounted on the intake manifold. Critical differentiation from EP3 petrol engines: EP3C features a chain-driven timing system, while earlier EP3 variants used a belt. Service parts for the EP3C are generally compatible across all 207 and 207 CC applications from 2006-2010.
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.
