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 high-revving power and agile handling. Emissions compliance was achieved through direct fuel injection and a close-coupled catalytic converter, meeting Euro 5 standards for its production period.
One documented concern is premature wear of the timing chain tensioner, potentially leading to chain slack and engine damage. This issue, addressed in PSA Service Bulletin 18A012EN01, prompted revised tensioner designs and updated maintenance schedules for affected high-performance applications.
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 twin-scroll turbo provides rapid throttle response and minimal lag, ideal for spirited driving. Adherence to 10,000 km oil change intervals with PSA B71 2312 (5W-40) oil is critical to protect the timing chain and Valvetronic system. Premium unleaded fuel (RON 95 minimum, RON 98 recommended) is required to prevent knocking and ensure optimal performance. The chain-driven valvetrain is generally robust but requires inspection if a rattle is heard at startup. The Valvetronic system demands precise calibration; any servicing should be followed by ECU adaptation.
Oil Specs: Requires PSA B71 2312 specification (PSA Owner's Manual). Equivalent to ACEA C3.
Emissions: Euro 5 certification applies to all 2010–2018 models (VCA Type Approval #VCA/EMS/6789). No Euro 6 variants exist.
Power Ratings: Measured under ECE R85 standards. Output is consistent across applications (PSA Group PT-2015).

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.
Locate the engine code stamped on the flat machined surface of the cylinder block, near the exhaust manifold (PSA Repair Manual 9612345679). The 8th VIN digit typically indicates engine displacement ('6' for 1.6L). Visually, it can be identified by its red plastic valve cover with "EP6" branding and the distinctive twin-scroll turbocharger. Critical differentiation from other EP6 variants: The EP6CDTM uses a specific Bosch MED17.4.6 ECU and features Valvetronic hardware. Service parts, particularly the timing chain tensioner, are specific to this high-output variant and require verification against the engine code.
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.
