The Peugeot 5FA (EP6CDT) was used across Peugeot's PF2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts and a performance-tuned exhaust in the RCZ R-and no significant facelift revisions occurred during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
The 5FA (EP6CDT)'s primary reliability risk is timing chain tensioner failure, with elevated incidence in vehicles with modified ECU maps or aggressive driving. PSA internal reports indicated a notable failure rate before 80,000 km in early production batches, while owner feedback frequently cites a distinctive rattle on cold start. Extended periods of high-RPM operation and infrequent oil changes accelerate tensioner wear, making maintenance adherence critical.
Analysis derived from PSA technical bulletins (2012-2016) 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 5FA offers thrilling performance but has a known weakness with its timing chain tensioner, especially in early models. With meticulous maintenance, use of correct oil (PSA B71 2310), and premium fuel, it can be reliable. Addressing the tensioner proactively or ensuring it's the revised version is key to long-term ownership. Avoid aggressive ECU tunes without supporting modifications.
The most frequent issues are timing chain tensioner failure, high-pressure fuel pump faults, turbo wastegate actuator problems, and intake valve carbon buildup. These are well-documented in PSA service bulletins and owner forums. Tensioner failure is the most critical, as it can lead to total engine destruction.
The high-performance 5FA (EP6CDT) 1.6L turbo petrol engine was fitted to the Peugeot 308 GTi (200/208) and the RCZ R from 2013 to 2015. It was the most powerful version of the Prince engine family in Peugeot's lineup at the time.
Yes, the 5FA responds very well to ECU remapping. Stage 1 tunes can safely increase power to around 240-250 PS and torque to 320-340 Nm. Stage 2 with a downpipe and intercooler can reach 270+ PS. The engine is robust, but pushing beyond 300 PS requires internal upgrades. Always address the timing tensioner first on early cars.
Real-world fuel economy is typical for a performance engine. In a Peugeot 308 GTi, expect around 8.5-9.5 L/100km (30-28 mpg UK) in mixed driving. Highway cruising can yield 6.5-7.0 L/100km (43-40 mpg UK). Aggressive driving will significantly increase consumption.
Yes. The 5FA (EP6CDT) is an interference engine. If the timing chain were to fail or jump due to tensioner issues, the pistons would collide with the open valves, causing catastrophic internal engine damage. This makes addressing any chain rattle immediately paramount.
Peugeot mandates the use of oil meeting the PSA B71 2310 specification, typically a 5W-40 synthetic. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is critical for protecting the turbocharger and catalytic converter from clogging and ensuring proper lubrication of the timing chain system.
