The Peugeot 5FE (EP6CDTMD) is a 1,598 cc, inline‑four turbocharged petrol engine produced between 2014 and 2021. It features a DOHC 16‑valve design with BMW‑developed Valvetronic variable valve lift and direct fuel injection. In standard applications, it delivers 151 kW (205 PS) and 300 Nm of torque, engineered for spirited performance in premium compact vehicles.
Fitted primarily to the Peugeot 308 GTi, RCZ R, and select Citroën DS models, the 5FE was designed for agile, responsive driving with an emphasis on mid‑range power delivery. Emissions compliance for its production period was achieved through a gasoline particulate filter (GPF) and dual oxygen sensors, meeting Euro 6 standards.
One documented reliability concern involves premature wear of the timing chain tensioner, potentially leading to rattling noises or timing faults. This issue, referenced in Peugeot Service Bulletin 18BZ03, is often linked to oil quality or infrequent changes. Later revisions saw updates to the tensioner material and lubrication passages.
Production years 2014–2021 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/8912).
The Peugeot 5FE (EP6CDTMD) is a 1,598 cc inline‑four turbocharged petrol engineered for premium hot hatches and coupes (2014-2021). It combines BMW-sourced Valvetronic variable valve lift with direct injection to deliver sharp throttle response and strong mid-range pull. Designed to meet stringent Euro 6 standards, it balances high performance with modern emissions control.

The twin-scroll turbo provides immediate throttle response and minimal lag, ideal for spirited driving. Strict adherence to 15,000 km oil change intervals with PSA B71 2312 (5W-30) oil is critical to protect the timing chain tensioner and Valvetronic system. The Bosch HDEV6 injectors require high-quality, low-sulfur petrol (ULSP) to prevent coking. The GPF system is sensitive to oil consumption; excessive burning can lead to premature filter clogging. Post-2016 engines feature an updated tensioner; pre-2016 units should have the upgrade per Peugeot SIB 18BZ03.
Oil Specs: Requires PSA B71 2312 (5W-30) specification (Peugeot Owner's Manual). Equivalent to ACEA C2.
Emissions: Euro 6 certification applies to all 2014–2021 models (VCA Type Approval #VCA/EMS/8912).
Power Ratings: Measured under ECE R85 standards. Output is consistent across specified fuel quality (Peugeot TIS Doc. B41000).

The Peugeot 5FE (EP6CDTMD) was used across PSA Group's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts for the RCZ R and specific cooling ducting for the 308 GTi-creating minor interchange considerations. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a plate riveted to the front of the cylinder block, near the alternator (Peugeot TIS B40122). The 8th VIN digit typically corresponds to the engine code ('F' for 5FE). Visually, the engine is identifiable by its black plastic intake manifold with integrated Valvetronic motor and the Mitsubishi twin-scroll turbo mounted at the rear of the engine. Critical differentiation from the EP6CDTX: The 5FE (EP6CDTMD) produces 205 PS and has specific ECU mapping for the GTi/RCZ R; parts are not interchangeable without reprogramming.
The 5FE's primary reliability risk is timing chain tensioner wear, with elevated incidence in vehicles using incorrect oil or extended service intervals. Peugeot internal reports indicate a notable number of replacements under warranty, while owner surveys frequently cite a cold-start rattle as a precursor. Aggressive driving and poor maintenance make adherence to the correct oil specification and timely tensioner upgrades critical.
