The Ford XUJA is a 1,499 cc, inline‑four turbo‑petrol engine produced between 2012 and 2018. It features direct fuel injection, a single twin-scroll turbocharger, and dual overhead camshafts (DOHC). In standard applications it delivers 118 kW (160 PS) and 240 Nm of torque, with strong mid-range response for everyday drivability.
Fitted to models such as the Focus Mk3 (C346), C-MAX, and Mondeo Mk5, the XUJA was engineered for drivers seeking a balance of performance and fuel economy. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a close-coupled three-way catalyst, enabling Euro 5 compliance across all production years.
One documented concern is carbon buildup on intake valves due to the absence of port fuel injection, highlighted in Ford Service Bulletin SSM 45892. This can lead to rough idle and reduced efficiency over time. From 2015, Ford introduced revised valve stem seals and updated ECU calibrations to mitigate oil consumption.
All production years (2012–2018) meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/FD2012XUJA).
The Ford XUJA is a 1,499 cc inline‑four turbo‑petrol engineered for compact and mid‑size models (2012–2018). It combines gasoline direct injection with a twin‑scroll turbocharger to deliver responsive mid‑range torque and efficient highway cruising. Designed to meet Euro 5 standards, it balances sporty performance with urban economy.

The twin-scroll turbo provides crisp throttle response ideal for urban and highway driving but requires high-quality fuel (RON 95 minimum) to prevent knock and injector coking. Ford WSS-M2C948-B (5W-30) oil is critical due to its low-SAPS formulation protecting the turbo bearing and timing chain. Extended oil change intervals beyond 16,000 km may accelerate carbon buildup on intake valves. Post-2015 models feature improved valve stem seals to reduce oil consumption; pre-2015 units should be monitored for blue exhaust smoke. The absence of port injection means intake cleaning may be needed every 60,000–80,000 km.
Oil Specs: Requires Ford WSS-M2C948-B (5W-30) specification (Ford SSM 45892). Equivalent to ACEA C2/C3 low-SAPS standards.
Emissions: Euro 5 certification applies to all XUJA production years (2012–2018) (VCA Type Approval #VCA/EMS/FD2012XUJA). No Euro 6 variants exist.
Power Ratings: Measured under ISO 1585 standards. Power output assumes RON 95 fuel (Ford TIS Doc. T14XUJA).

The Ford XUJA was used across Ford's C346/CD391 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Mondeo and revised intake manifolds in the Focus ST-Line—and from 2015 the facelifted C-MAX adopted updated ECU calibrations for smoother idle, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crank pulley (Ford TIS T14XUJA). The 8th VIN digit indicates engine displacement ('J' for 1.5L EcoBoost). All XUJA units use black plastic valve covers with '1.5 EcoBoost' branding. Critical differentiation from later 1.5L engines (e.g., XUJB): XUJA uses a single twin-scroll turbo and lacks cylinder deactivation. ECU part number begins with '14Dxxx' for pre-2015 and '15Dxxx' for post-facelift units. Software and injector calibrations are not interchangeable across model years without reprogramming.
The XUJA's primary reliability risk is intake valve carbon buildup due to direct-only fuel injection, with elevated incidence in short-trip urban use. Ford internal data (2016) noted increased service visits for rough idle after 60,000 km in city-driven vehicles, while UK DVSA records show no significant emissions-related MOT failures linked to this engine. Extended oil change intervals and low-quality fuel amplify deposit formation, making maintenance adherence critical.
