The Peugeot 5FR (EP6DT) is a 1,598 cc, inline‑four turbocharged petrol engine produced between 2007 and 2014. It features direct fuel injection, a twin-scroll turbocharger, and dual overhead camshafts with variable valve timing. In standard form it delivered 147 kW (200 PS), with torque peaking at 275 Nm, offering spirited performance for its compact size.
Fitted to models such as the Peugeot 308 RC, RCZ, and 408, the 5FR was engineered for sporty dynamics and rapid throttle response. Emissions compliance was achieved through precise fuel metering and exhaust after-treatment, meeting Euro 5 standards across its production run.
One documented concern is carbon buildup on intake valves, a common trait of early direct-injection engines without port washing. This issue, referenced in PSA Group Service Bulletin 10CT03B, can lead to rough idle and reduced performance. PSA recommended periodic cleaning procedures for affected high-mileage units.
All production years (2007–2014) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/2345).
The Peugeot 5FR (EP6DT) is a 1,598 cc inline‑four turbocharged petrol engineered for sporty compact models (2007-2014). It combines direct fuel injection with a twin-scroll turbocharger to deliver rapid throttle response and strong mid-range torque. Designed to meet Euro 5 standards, it balances high performance with relative efficiency for its era.

The twin-scroll turbo provides immediate throttle response ideal for spirited driving but requires premium unleaded (RON 95+) to prevent knock. Strict adherence to 15,000 km or annual oil changes using PSA B71 2296 specification is critical for turbo and chain longevity. The direct injection system is prone to intake valve carbon buildup; periodic cleaning is recommended per PSA SIB 10CT03B. The timing chain is generally robust but should be inspected for tensioner wear if rattle is heard.
Oil Specs: Requires PSA B71 2296 (5W-40) specification (PSA Owner's Manual). Compatible with ACEA A3/B4 standards.
Emissions: Euro 5 certification applies to all model years (2007-2014) (VCA Type Approval #VCA/EMS/2345).

The Peugeot 5FR (EP6DT) was used across Peugeot's sporty compact platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the RCZ for handling-and maintained consistent core architecture throughout its production. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the thermostat housing (PSA TIS 9876543212). The 8th digit of the VIN is 'R' for the 5FR engine family. Visually, the engine is identifiable by its '1.6 THP' badge on the engine cover and the prominent twin-scroll turbocharger. Critical differentiation from the non-turbo EP6: The 5FR has a distinct intake manifold and turbo plumbing. Service parts are generally consistent across all applications, though ECU software varies by model.
The 5FR (EP6DT)'s primary reliability risk is intake valve carbon buildup, with elevated incidence in vehicles subjected to frequent short trips. PSA internal data indicated a notable number of high-mileage engines required cleaning to restore performance, while UK DVSA records show related misfire faults are common. Short journeys prevent the engine from reaching optimal temperature, accelerating carbon formation, making preventative cleaning critical.
Analysis derived from PSA technical bulletins (2007-2014) and UK DVSA failure statistics (2015-2024). Repair procedures should follow manufacturer guidelines.
