The Ford XUJK is a 1,999 cc, inline‑four turbo‑petrol engine produced between 2020 and 2025. It features a DOHC 16‑valve architecture, direct fuel injection, and a single twin‑scroll turbocharger. In standard form it delivers 177 kW (240 PS) and 370 Nm of torque, with a broad powerband optimized for responsive daily driving and highway overtaking.

All production years (2020–2025) comply with Euro 6d emissions standards .
The Ford XUJK is a 1,999 cc inline‑four turbo‑petrol engineered for compact performance models (2020–2025). It combines direct injection with a twin‑scroll turbocharger to deliver strong mid-range torque and agile throttle response. Designed to meet Euro 6d standards, it balances sporty character with regulatory compliance.

The Ford XUJK was used across Ford's C‑Car and CD‑Car platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—enhanced cooling in the Focus ST, reinforced mounts in the Kuga ST‑Line X, and revised ECU calibration in the Puma ST—and from early 2023 the HPFP upgrade created minor service part interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The XUJK is generally robust when maintained correctly. Early models (2020–early 2023) had HPFP durability concerns, addressed from 2023 onward. Using the correct 0W-20 Ford-spec oil, adhering to service intervals, and avoiding chronic short-trip driving greatly improve longevity. The timing chain shows no widespread issues.
Top issues include HPFP cam follower wear (pre-2023), GPF clogging from urban use, turbo wastegate rattle, and oil dilution in cold climates. These are documented in Ford TSBs and addressed with updated service parts.
The 2.0L XUJK powers the Focus ST (2020–2025), Kuga ST-Line X (2020–2025), and Puma ST (2021–2025). It is exclusive to Ford and not shared with other manufacturers.
Aftermarket ECU tuning is common on the XUJK platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Focus ST, expect ~8.5 L/100km (city) and ~6.2 L/100km (highway), or ~34 mpg UK combined. Real-world mixed driving typically returns 30–36 mpg UK, depending on driving style and GPF regeneration cycles.
Yes. The XUJK is an interference engine. Timing chain failure—though rare—could cause piston-to-valve contact and severe internal damage. No widespread chain issues have been reported.
Ford specifies SAE 0W-20 oil meeting WSS-M2C949-A. This low-viscosity oil is critical for HPFP lubrication and GPF compatibility. Never substitute with 5W-30 or non-approved oils.
