The Citroen UFZ (ZPJ/Z) is a 1,199 cc, inline — three turbocharged petrol engine produced between 2014 and 2020. Part of the PSA — Empire joint — venture "EB" engine family developed with Dongfeng and used across the Stellantis group, it delivers responsive performance in a compact footprint. Equipped with a single overhead camshaft (SOHC), multi — point fuel injection, and a low — inertia turbocharger, it produces 81 kW (110 PS) with 170 Nm of torque, enabling strong low — en…
Production years 2014–2020 meet Euro 5b standards (VCA UK Type Approval #VCA/EMS/9123).
The Citroen UFZ (ZPJ/Z) is a 1,199 cc inline-three turbocharged petrol engine engineered for compact city cars (2014–2020). It combines SOHC 12-valve architecture with a low-inertia turbocharger to deliver responsive, torque-rich performance. Designed to meet Euro 5b emissions standards, it balances drivability with fuel efficiency and low emissions.

The Citroen UFZ (ZPJ/Z) was used across Citroen's C3 platform with transverse mounting and shared with Peugeot under PSA platform commonality. This engine received model-specific tuning-for sharper throttle response in the C3-and from 2017 the updated turbo actuator with revised heat shielding, creating interchange limits. Partnerships within the Stellantis Group allowed Peugeot's 208 to use identical powertrain calibration. All adaptations are documented in OEM technical bulletins.
The UFZ (ZPJ/Z)'s primary reliability risk is turbocharger wastegate actuator failure on early builds, with elevated incidence in high-mileage vehicles. PSA internal reports from 2017 noted a significant number of pre-2017 engines requiring actuator replacement before 100,000 km, while UK DVSA MOT records show emissions-related failures linked to turbo performance. Extended stop-start cycles and short-trip driving increase carbon risk, making adherence to maintenance schedules critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The UFZ (ZPJ/Z) offers dependable performance when properly maintained. Early models (2014–2016) are prone to turbo actuator issues, but post-2017 revisions resolved this. Timing belt integrity is critical—replacement every 100,000 km or 5 years is mandatory. With regular oil changes and cooling system maintenance, these engines can exceed 150,000 km.
Key issues include turbo wastegate actuator sticking in pre-2017 engines, timing belt failure due to neglect, idle instability from carbon buildup, and coolant leaks from the thermostat housing. These are documented in PSA technical bulletins and remain the most frequently reported concerns in service networks.
The UFZ (ZPJ/Z) was used exclusively in the Citroën C3 (1.2 PureTech 110) from 2014 to 2020. It was also shared with the Peugeot 208 (1.2 PureTech 110) during the same period. No other Citroën models received this specific engine variant.
Yes. The turbocharged design allows for safe ECU remaps yielding +20–30 kW. Performance gains are substantial due to conservative factory tuning. Upgrades like intake, exhaust, and intercooler are possible but require careful matching. Most owners enjoy the improved responsiveness without major modifications.
In the C3 1.2 PureTech 110, fuel consumption averages ~6.8 L/100km (city) and ~4.6 L/100km (highway), or about 41 mpg UK combined. Real-world economy varies with driving style, but 38–42 mpg (UK) is typical for mixed use. Fuel quality meeting EN 228 is essential for optimal performance.
Yes. The UFZ (ZPJ/Z) is an interference engine. If the timing belt fails, pistons contact open valves, causing severe internal damage. That's why strict adherence to the 100,000 km or 5-year replacement interval is absolutely critical.
PSA specifies SAE 5W-30 oil meeting ACEA C3 standards. Use high-quality synthetic oil and change every 15,000 km or annually. Proper oil selection ensures turbocharger longevity and protects emissions systems, especially in early production engines.
