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 agil…
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 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.
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.
Analysis derived from Peugeot technical bulletins (2016-2020) and UK DVSA failure statistics (2018-2023). 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 potent and generally robust engine when maintained correctly. Its main weakness is the early-design timing chain tensioner, which can wear prematurely if serviced incorrectly. The Valvetronic system is sophisticated but reliable with proper care. Using the correct 5W-30 oil and adhering to service intervals is paramount for maximizing longevity.
The most frequent issues are timing chain tensioner wear causing a cold-start rattle, failures of the Valvetronic motor leading to power loss, and occasional high-pressure fuel pump failures. GPF clogging is also common in vehicles used primarily for short urban trips. These are covered in Peugeot service documentation.
The 5FE (EP6CDTMD) 1.6 THP 205 engine was used in the high-performance Peugeot 308 GTi (2015-2021) and the limited-run RCZ R coupe (2014-2015). It was also fitted to the Citroën DS3 Performance model (2015-2019). It was not used in standard 308 or 208 models.
Yes, the 5FE responds very well to tuning. Stage 1 ECU remaps can safely increase power to 240-260 PS and torque to 350+ Nm. The stock internals, including the turbo, are strong enough for these gains. More aggressive tuning requires an upgraded intercooler and downpipe. It remains a popular choice for tuners seeking a balance of power and daily drivability.
Real-world fuel economy reflects its performance nature. In a Peugeot 308 GTi, expect around 8.5 L/100km (33 mpg UK) in combined driving. Highway cruising can yield 6.5-7.0 L/100km (40-43 mpg UK), while enthusiastic city driving may exceed 11.0 L/100km (26 mpg UK). Results vary significantly with driving style.
Yes. The 5FE is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal damage. Fortunately, the chain itself is very durable; the tensioner is the primary point of concern.
Peugeot mandates oil meeting the PSA B71 2312 specification, typically a 5W-30 synthetic. Using the correct low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is vital for protecting the GPF and ensuring proper lubrication of the Valvetronic system and timing chain. Always change the oil and filter at the recommended 15,000 km intervals.
