The Peugeot 5FV (EP6CDT) is a 1,598 cc, inline‑four turbocharged petrol engine produced between 2007 and 2015. It features an aluminum block and head, dual overhead camshafts, and a twin — scroll turbocharger for enhanced response. In standard form, it delivered 147 kW (200 PS) and 275 Nm of torque, engineered for sporty performance in premium compact models.
Fitted to models like the Peugeot 308 RC and 207 RC, the 5FV was designed for drivers seeking agile handling and rapi…
Production years 2007–2015 meet Euro 5 standards exclusively (VCA UK Type Approval #VCA/EMS/7890).
The Peugeot 5FV (EP6CDT) is a 1,598 cc inline‑four turbocharged petrol engineered for high-performance hatchbacks (2007-2015). It combines direct fuel injection with a twin-scroll turbocharger to deliver responsive power and strong mid-range torque. Designed to meet Euro 5 standards, it balances dynamic performance with regulatory compliance.

The Peugeot 5FV (EP6CDT) was used across PSA Group's performance platforms with transverse mounting. This engine received platform-specific adaptations-shared ECU mapping with the 207 RC and unique engine mounts for the 308 RC-with minor revisions in 2012 for the timing system. All adaptations are documented in OEM technical bulletins.
The 5FV (EP6CDT)'s primary reliability risk is timing chain tensioner failure, with elevated incidence in high-RPM usage. PSA internal quality reports noted a significant number of premature tensioner wear cases under warranty, while owner feedback frequently cites extended oil change intervals as a contributing factor. Aggressive driving and insufficient lubrication make adherence to OEM maintenance schedules critical.
Analysis derived from PSA technical bulletins (2008-2015) and owner-reported failure data (2010-2023). 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 5FV is a capable performance engine with a robust aluminum block. Its main weakness is the timing chain tensioner, which can fail prematurely with poor maintenance or aggressive driving. With strict adherence to service intervals, especially using correct oil and premium fuel, it can be very reliable long-term.
The most frequent issues are timing chain tensioner wear, high-pressure fuel pump failure, turbo actuator faults, and valve cover gasket leaks. These are well-documented in PSA service bulletins and owner forums, with the timing chain being the most critical concern for engine longevity.
This high-output engine was used in the Peugeot 207 RC (2007-2013) and the Peugeot 308 RC (2010-2015), both badged as 1.6 THP 200. It is a core part of PSA's performance lineup for these specific hot hatch models.
Yes, it has excellent tuning potential. A Stage 1 ECU remap can safely increase power to around 220-240 PS and torque to 300+ Nm. The engine's internals are strong, but supporting modifications like an upgraded intercooler and downpipe are recommended for higher stages to ensure reliability.
Expect combined fuel economy of around 35-40 mpg (UK) or 7.0-6.0 L/100km in a Peugeot 308 RC. Real-world figures vary significantly with driving style; aggressive driving can drop economy to 25 mpg, while gentle highway cruising may yield up to 45 mpg.
Yes. Like all modern engines, the 5FV is an interference design. If the timing chain were to fail or skip, the pistons would collide with the open valves, causing catastrophic internal engine damage. This makes addressing any timing chain noise immediately critical.
Peugeot specifies oil meeting the PSA B71 2312 standard, typically a 5W-40 synthetic. Using the correct specification is vital for protecting the timing chain and turbocharger. Extended drain intervals or incorrect oil can lead to premature wear.
