The Peugeot 1.6L THP 200 (engine code EP6CDTX) is a 1,598 cc, inline‑four turbocharged petrol engine produced between 2010 and 2018. It features a double overhead camshaft (DOHC), 16‑valve architecture with direct fuel injection and a twin‑scroll turbocharger. Peak output is 147 kW (200 PS) at 6,000 rpm with 275 Nm of torque at 1,700 rpm, delivering strong performance with refined response.
Fitted to performance variants such as the Peugeot RCZ R, 308 GTi, and 208 GTi, the…

All production years (2010–2018) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9432). No Euro 6 variants exist under the EP6CDTX designation.
The Peugeot 1.6L THP 200 (EP6CDTX) is a 1,598 cc inline‑four turbocharged petrol engine engineered for hot hatch and coupe applications (2010–2018). It combines DOHC valvetrain architecture with direct injection and a twin-scroll turbocharger to deliver high specific output and responsive torque. Designed to meet Euro 5 emissions standards, it balances performance with regulatory compliance.

The Peugeot 1.6L THP 200 (EP6CDTX) was used across PSA Group's PF2 and PF1 platforms with transverse mounting and shared with Citroën and MINI under joint development. This engine received platform-specific adaptations—reinforced mounts in the RCZ R and modified intercooler routing in the 308 GTi—and from 2015 the updated engine management strategies created minor calibration differences. All adaptations are documented in OEM technical bulletins.
The EP6CDTX's primary reliability risk is carbon buildup on intake valves due to direct injection, with elevated incidence in urban or short-trip driving. PSA internal quality reports from 2014 noted measurable power loss and misfires before 70,000 km in city-driven vehicles, while owner surveys confirm rough idle as a frequent complaint. Extended oil intervals and low-quality fuel accelerate deposit formation, making fuel quality and maintenance discipline critical.
Analysis derived from PSA technical bulletins (2011–2016) and Peugeot Sport Owner Club reliability surveys (2013–2020). 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 EP6CDTX is robust if maintained correctly. Carbon buildup on intake valves is the main concern, especially with urban driving. Regular oil changes, premium fuel, and periodic intake cleaning greatly extend engine life. Later models (2015+) benefit from improved engine management strategies.
Top issues include intake valve carbon buildup, high-pressure fuel pump failure, timing chain tensioner wear, and turbo wastegate sticking. These are documented in PSA service bulletins SI‑11‑07 and TIS updates from 2012–2015.
Primarily the Peugeot RCZ R (2013–2015), 208 GTi (2014–2018), and 308 GTi (2015–2018). It was also used in the Citroën DS3 Racing/R and MINI Cooper S (N18 variant) under the BMW-PSA joint engine program.
Yes—ECU remapping commonly yields +30–40 PS safely. The stock internals handle up to ~240 PS with supporting upgrades (intercooler, exhaust, fuel system). Many owners achieve 220–230 PS reliably. Always use RON 98 fuel and monitor temperatures.
Typical consumption is ~8.5 L/100km (city) and ~6.0 L/100km (highway), or 33–47 mpg UK combined. Real-world figures depend heavily on driving style—enthusiastic use increases consumption significantly.
Yes. The EP6CDTX is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing severe internal damage. Prompt attention to chain rattle or timing faults is essential.
PSA specifies 5W‑40 synthetic oil meeting ACEA A3/B4 and PSA B71 2290 standards. Change every 15,000 km or annually to protect the turbo, timing chain, and high-pressure fuel system.
