The Peugeot 5FT (EP6DT) is a 1,598 cc, inline‑four turbo‑petrol engine produced between 2010 and 2015. It features a 16‑valve DOHC layout with variable valve timing (VVT) and direct fuel injection, paired with a twin‑scroll turbocharger to deliver 156 kW (211 PS) and 275 Nm of torque. This compact powerplant was engineered for responsive performance, offering strong low‑end pull and linear power delivery.
Fitted primarily to sporty variants of the 308 and RCZ, the 5FT was designed for agile, spirited driving. Emissions compliance for its production period was achieved through precise fuel metering and catalytic conversion, enabling adherence to the Euro 5 standard across its core European markets.
A documented reliability concern involves premature wear of the timing chain tensioner, potentially leading to rattling noises or timing faults. This issue, referenced in PSA Group Service Bulletin 12A005, is often attributed to oil quality or infrequent changes. The tensioner design was revised in later production runs to improve durability.
Production years 2010–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/PSA/5FT).
The Peugeot 5FT (EP6DT) is a 1,598 cc inline‑four turbo‑petrol engineered for compact performance models (2010-2015). It combines gasoline direct injection with a twin‑scroll turbocharger to deliver sharp throttle response and high specific output. Designed to meet Euro 5 standards, it balances sporty performance with acceptable fuel economy.

The twin-scroll turbo provides immediate throttle response ideal for spirited driving but demands strict 15,000 km or annual oil changes to prevent timing chain tensioner wear. PSA B71 2312 (5W-40) oil is critical for turbo and chain longevity. The Bosch direct injection system is sensitive to fuel quality; premium unleaded (98 RON) is recommended to prevent carbon buildup on intake valves. The chain-driven valvetrain is generally robust but should be inspected for tensioner wear after 100,000 km per PSA SIB 12A005.
Oil Specs: Requires PSA B71 2312 specification (PSA Service Schedule). Equivalent to ACEA C3.
Emissions: Euro 5 certification applies to all 2010–2015 models (VCA Type Approval #VCA/PSA/5FT).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (PSA Group PT-2012).

The Peugeot 5FT (EP6DT) was used across Peugeot's PF2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the RCZ-and no significant facelift revisions occurred during its production run, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the rear of the cylinder block, near the flywheel housing (PSA Repair Manual 5FT). The 8th digit of the VIN is 'P' for this 1.6 THP 200 engine variant. Visually, it can be identified by its red plastic rocker cover and the Honeywell twin-scroll turbocharger mounted at the front. Critical differentiation from the lower-powered EP6CDT: The 5FT has a higher power output (211 PS vs 156 PS) and a distinct ECU calibration. Service parts, particularly the turbocharger and injectors, are specific to the 5FT and not interchangeable with other EP6 variants without verification.
The 5FT's primary reliability risk is timing chain tensioner wear, with elevated incidence in vehicles using incorrect oil or exceeding service intervals. PSA internal data indicated a notable failure rate before 120,000 km in affected batches, while owner reports frequently cite a distinctive rattle on cold start. Poor oil quality increases tensioner stress, making oil specification and adherence to service schedules critical.
Analysis derived from PSA technical bulletins (2010-2015) and owner-reported failure data (2015-2023). Repair procedures should follow manufacturer guidelines.
