The Peugeot 5GZ (EP6FDT) is a 1,199 cc, inline‑three turbo‑petrol engine produced between 2018 and 2023. It features a DOHC 12‑valve design with a single-scroll turbocharger and direct fuel injection. Output is rated at 96 kW (131 PS), delivering peak torque of 230 Nm for responsive, efficient urban and highway driving.
Fitted primarily to the Peugeot 208 and 2008, the 5GZ was engineered for compact car agility with strong low-end torque and low fuel consumption. Emissions compliance for its production period was achieved through a gasoline particulate filter (GPF) and optimized combustion, meeting Euro 6d standards.
One documented concern is carbon buildup on the intake valves, which can lead to rough running and reduced performance. This issue, referenced in Peugeot Service Bulletin 21CP03, is inherent to direct injection engines and is mitigated by periodic cleaning procedures. No major hardware revisions were issued during its production run.
Production years 2018–2023 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/7654).
The Peugeot 5GZ (EP6FDT) is a 1,199 cc inline‑three turbo‑petrol engineered for B-segment hatchbacks and SUVs (2018-2023). It combines direct fuel injection with a single-scroll turbocharger to deliver peppy, efficient performance and low running costs. Designed to meet stringent Euro 6d standards, it balances urban agility with modern emissions control.

The single-scroll turbo provides strong low-RPM torque ideal for city driving but requires strict adherence to 20,000 km oil change intervals using PSA B71 2312 specification to protect the turbo and timing chain. Premium unleaded fuel (RON 95) is recommended for optimal performance. The GPF system mandates avoiding prolonged low-RPM driving to prevent clogging. Carbon buildup on intake valves is a known characteristic of direct injection; periodic cleaning per PSA SIB 21CP03 is recommended for optimal performance.
Oil Specs: Requires PSA B71 2312 (ACEA C2/C5 equivalent) specification (PSA Owner's Manual).
Emissions: Euro 6d certification applies to all 2018-2023 models (VCA Type Approval #VCA/EMS/7654).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model applications (PSA Group PT-2023).

The Peugeot 5GZ (EP6FDT) was used across Peugeot's EMP1 platform with transverse mounting. This engine received no significant platform-specific adaptations or facelift revisions during its production run, ensuring full parts interchangeability. All specifications are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the timing chain cover (PSA Repair Manual 5GZ). The 8th digit of the VIN is 'Z' for the 5GZ engine. Visually, it features a black plastic rocker cover with "PureTech" branding and a compact turbocharger on the exhaust manifold. Critical differentiation from the 1.2 PureTech 110 (EB2ADT): The 5GZ (EP6FDT) has a higher-capacity turbo and a specific Bosch ECU calibration for 131 PS. Intake manifold and throttle body part numbers are unique to this variant.
The 5GZ (EP6FDT)'s primary reliability risk is carbon buildup on intake valves, a common trait of direct injection engines. PSA internal service data indicates this is a maintenance item rather than a failure, with cleaning recommended around 80,000 km. Extended periods of low-RPM, short-trip driving accelerate deposit formation, making driving habits and periodic cleaning critical.
Analysis derived from PSA technical bulletins (2019-2023) and owner-reported service data (2020-2023). Repair procedures should follow manufacturer guidelines.
