The Citroën PureTech 180 is a 1,598 cc, inline-three turbocharged petrol engine produced between 2017 and 2023. It forms part of Stellantis' modular engine family, designed for compact and mid-size platforms. Featuring direct fuel injection, variable valve timing (VVT), and a twin-scroll turbocharger, it delivers 132 kW (180 PS) and 290 Nm of torque. Its compact design and thermal efficiency support both front-wheel-drive and mild-hybrid applications.
Fitted to models such as the C4, C5 Aircross, and DS 7 Crossback, the PureTech 180 was engineered for responsive urban and highway performance with improved fuel economy over larger naturally aspirated units. Emissions compliance is achieved through a three-way catalytic converter and gasoline particulate filter (GPF), meeting Euro 6b standards in pre-2020 builds and Euro 6d-TEMP from 2020 onward.
One documented concern is premature turbocharger bearing wear, particularly in early 2017–2019 units operating under frequent short-trip cycles. This issue, referenced in Stellantis Technical Service Bulletin PEA-19-007, is linked to oil coking in the turbocharger housing due to insufficient warm-up periods. From 2020, revised oil cooler routing and updated turbocharger sealing were introduced to improve longevity.
Production years 2017–2019 meet Euro 6b standards; 2020–2023 models comply with Euro 6d-TEMP (VCA UK Type Approval #VCA/EMS/5678).
The Citroën PureTech 180 is a 1,598 cc inline-three turbocharged petrol engine engineered for compact SUVs and hatchbacks (2017–2023). It combines direct injection with a twin-scroll turbocharger to deliver strong mid-range torque and responsive acceleration. Designed to meet Euro 6d-TEMP emissions standards, it balances performance with urban fuel efficiency.

The twin-scroll turbo provides strong mid-range torque ideal for overtaking and hill climbing but requires consistent warm-up cycles to prevent oil coking in the turbocharger. Stellantis B71 2290 (0W-20) oil is critical due to its low viscosity ensuring rapid flow to the turbo and timing chain. Short-trip driving without full warm-up increases risk of turbo bearing wear and GPF saturation. The Bosch HDEV5 fuel system demands TOP TIER petrol to prevent injector deposits. From 2020, revised oil cooler routing reduces thermal stress. GPF regeneration should not be interrupted to maintain emissions compliance.
Oil Specs: Requires Stellantis B71 2290 (0W-20) specification (Stellantis SIB PEA-19-007). Replaces ACEA C2/C3.
Emissions: Euro 6b certification applies to pre-2020 models only (VCA Type Approval #VCA/EMS/5678). Euro 6d-TEMP applies from 2020 onward.
Power Ratings: Measured under ECE R85 standards. Full output requires 98 RON fuel (Stellantis TIS Doc. P1500-PWR).

The Citroën PureTech 180 was used across Citroën's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-shorter intake manifolds in the C4 and reinforced engine mounts in the C5 Aircross-and from 2020 the facelifted C4 Gen2 adopted a 48V mild-hybrid variant (EHD1), creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left-side cylinder block near the transmission bellhousing (Stellantis TIS P1500-ID). The 8th VIN digit indicates engine family ('G' for PureTech 180). Pre-2020 models have silver valve covers with black plastic intake manifolds; post-2020 mild-hybrid variants feature a 48V belt alternator starter (BAS) unit. Critical differentiation from PureTech 130: PureTech 180 uses a twin-scroll turbocharger and larger intercooler. Service parts require model year verification—turbochargers for pre-2020 units are incompatible with EHD1 hybrid variants due to revised exhaust manifolds (Stellantis SIB PEA-20-015).
The PureTech 180's primary reliability risk is turbocharger bearing wear on early builds, with elevated incidence in urban short-trip use. Internal Stellantis quality reports from 2019 noted a significant share of pre-2020 engines requiring turbo inspection before 100,000 km, while UK DVSA records show GPF-related faults are common in stop-start driving. Frequent cold starts and interrupted warm-up cycles increase turbo and GPF stress, making driving pattern and oil adherence critical.
