The Peugeot 5FE (EP6CDTM) is a 1,598 cc, inline‑four turbocharged petrol engine produced between 2010 and 2018. It features an aluminum block and head, dual overhead camshafts, and BMW — sourced Valvetronic variable valve lift technology. In standard form, it delivered 151 kW (205 PS) and 275 Nm of torque, engineered for sporty performance in premium compact models.
Fitted primarily to the Peugeot RCZ R and select 308 GTi variants, the 5FE was designed for drivers seeking…
Production years 2010–2018 meet Euro 5 standards exclusively (VCA UK Type Approval #VCA/EMS/6789).
The Peugeot 5FE (EP6CDTM) is a 1,598 cc inline‑four turbocharged petrol engineered for high-performance hatchbacks and coupes (2010-2018). It combines BMW-derived Valvetronic variable valve lift with direct injection to deliver responsive power and strong mid-range torque. Designed to meet Euro 5 standards, it prioritizes dynamic performance while maintaining regulatory compliance.

The Peugeot 5FE (EP6CDTM) was used across PSA Group's performance platforms with transverse mounting and shared with BMW. This engine received platform-specific adaptations-shared ECU mapping with the RCZ R and unique engine mounts for the 308 GTi-with no significant facelift revisions during its production run. The engine is a derivative of the BMW N13 engine family, adapted for PSA's chassis. All adaptations are documented in OEM technical bulletins.
The 5FE (EP6CDTM)'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 (2013-2018) and owner-reported failure data (2015-2023). 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 5FE is a high-performance engine with a robust aluminum block, capable of high mileage. Its main weaknesses are the timing chain tensioner and high-pressure fuel pump, 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, Valvetronic system faults, and turbo actuator problems. These are well-documented in PSA service bulletins and enthusiast forums, with the timing chain being the most critical concern for engine longevity.
This high-output engine was used in the limited-production Peugeot RCZ R (2013-2015) and the second-generation Peugeot 308 GTi (2015-2018). It is a PSA adaptation of the BMW N13 engine, specifically tuned for these performance models and not found in standard Peugeot variants.
Yes, it has excellent tuning potential. A Stage 1 ECU remap can safely increase power to around 240-260 PS and torque to 320+ Nm. The engine's internals, including the forged crankshaft in the RCZ R, are strong. For higher stages, supporting modifications like an upgraded intercooler, downpipe, and clutch are recommended to ensure reliability.
Expect combined fuel economy of around 35-40 mpg (UK) or 7.0-6.0 L/100km in a Peugeot 308 GTi. 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. The RCZ R, being heavier, typically returns slightly less.
Yes. Like all modern engines, the 5FE 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, turbocharger, and Valvetronic system. Extended drain intervals or incorrect oil can lead to premature wear.
