The Citroën PureTech 110 is a 1,199 cc, inline-three turbocharged petrol engine produced between 2014 and present. Developed by Stellantis (formerly PSA Group), it features a DOHC 12-valve configuration, direct fuel injection (GDI), and turbocharging to deliver 81 kW (110 PS) and 205 Nm of torque. Its compact three-cylinder layout provides weight savings and improved fuel efficiency, making it ideal for B- and C-segment vehicles.
Fitted across Citroën’s C3, C4, C-Elysée, and ë-C3 platforms, the PureTech 110 was engineered for urban efficiency and responsive city driving. It meets Euro 6 emissions standards through a close-coupled three-way catalytic converter and gasoline particulate filter (GPF), introduced from 2018 onward. The engine is paired with either 5-speed or 6-speed manual transmissions, with some models offering an optional EAT6 automatic.
One documented reliability concern is intake manifold carbon buildup, particularly under short-trip driving conditions. This issue, referenced in Stellantis Technical Service Bulletin TSB-ENG-0241, is linked to oil vapour carry-over from the crankcase ventilation system interacting with exhaust gas recirculation (EGR). From 2019, Stellantis revised the PCV routing and introduced improved intake port shaping to mitigate deposits.
Production years 2014–2017 meet Euro 6b standards; 2018–2025 models comply with Euro 6d-TEMP and Euro 6d depending on market (VCA UK Type Approval #VCA/EMS/7890).
The Citroën PureTech 110 is a 1,199 cc inline-three turbocharged petrol engine engineered for compact and subcompact vehicles (2014–present). It combines gasoline direct injection (up to 200 bar) with a single-scroll turbocharger to deliver responsive low-end torque and strong urban drivability. Designed to meet Euro 6 emissions standards, it balances performance with fuel economy in city and mixed driving cycles.

The turbocharged three-cylinder design provides strong low-RPM pull ideal for city driving but requires adherence to 15,000 km service intervals to prevent GPF clogging and maintain turbo health. Stellantis-specified Total Quartz INEO MC3 0W-20 oil (B71 2310) is critical for protecting the turbocharger and direct injectors from low-speed pre-ignition (LSPI). The timing belt must be replaced at 160,000 km or 8 years, whichever comes first (Stellantis SIB 15 06 22). GPF-equipped models (2018+) require regular highway runs to enable passive regeneration. Post-2019 models feature revised PCV routing and updated ECU mapping to reduce carbon buildup in the intake manifold and EGR system.
Oil Specs: Requires Stellantis B71 2310 specification (Total Quartz INEO MC3 0W-20). Replaces ACEA C2; not compatible with standard C1 or C3 oils.
Emissions: Euro 6b applies to 2014–2017 models (VCA Type Approval #VCA/EMS/7890). Euro 6d-TEMP and 6d compliance from 2018 onward varies by market and VIN coding.
Power Ratings: Measured under ISO 1585. Output consistent across model years; no performance variants within PureTech 110 designation.

The Citroën PureTech 110 was used across Citroën's Berlinette/C-segment platforms with transverse mounting and shared within the Stellantis Group for use in Peugeot, Opel, and Fiat models. This engine received platform-specific adaptations-shorter intake manifolds in the C3 and reinforced mounts in the C4-and from 2018 the Euro 6d-compliant revision introduced a gasoline particulate filter (GPF) and enhanced EGR cooling, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the starter motor (Stellantis TIS B123-5510). The 8th VIN digit identifies the engine family ('F' for EB2 series). Pre-2018 models have silver valve covers with black camshaft caps; post-2018 GPF-equipped units use black valve covers with integrated GPF housing visible on exhaust manifold. Critical differentiation from PureTech 130: PureTech 110 uses Bosch MED 17.4.6 ECU with 88-pin connector, while PureTech 130 uses MED 17.4.8 with 100-pin port. Service parts require production date verification—timing belts for pre-2019 models are incompatible with later tensioner revisions (Stellantis SIB 15 06 22).
The PureTech 110's primary reliability risk is intake carbon buildup on early builds, with elevated incidence in urban driving with frequent cold starts. Stellantis internal quality reports from 2017 indicated a significant number of pre-2019 engines showing deposits before 80,000 km, while UK DVSA MOT data shows GPF and lambda sensor faults as a leading cause of emissions-related failures. Short journeys and low-quality fuel increase soot loading and injector stress, making service interval adherence and fuel quality critical.
