The Ford XTDB is a 1,499 cc, inline‑three turbo‑petrol engine produced between 2018 and 2023. It features a compact DOHC 12‑valve layout, direct fuel injection, and a single twin‑scroll turbocharger. In standard form it delivers 118 kW (160 PS) and 250 Nm of torque, with strong low‑rpm response for urban and motorway driving.
Fitted to models such as the Fiesta ST, Puma ST, and Focus ST‑Line, the XTDB was engineered for sporty yet efficient performance. Emissions complian…
Production years 2018–2020 meet Euro 6d TEMP standards; 2021–2023 models comply with Euro 6d .
The Ford XTDB is a 1,499 cc inline‑three turbo‑petrol engineered for compact performance models (2018–2023). It combines direct injection with a twin‑scroll turbocharger to deliver responsive torque and agile throttle response. Designed to meet Euro 6d TEMP and Euro 6d standards, it balances sporty character with regulatory compliance.

The Ford XTDB was used across Ford's B‑Car and C‑Car platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Fiesta ST and enhanced cooling in the Puma ST—and from 2021 the facelifted Focus adopted revised engine control calibrations for GPF efficiency, creating minor ECU 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 XTDB is generally robust when maintained correctly. Early models (2018–2020) had HPFP durability concerns, addressed from mid-2021 onward. Using the correct 0W-20 Ford-spec oil and avoiding chronic short-trip driving greatly improves longevity. The timing chain shows no widespread issues.
The top issues are high-pressure fuel pump wear (pre-2021), GPF clogging from urban use, turbo wastegate rattle, and occasional oil consumption. These are documented in Ford TSBs and addressed with updated service parts.
The 1.5L XTDB powers the Fiesta ST (2018–2023), Puma ST (2019–2023), and Focus ST-Line/Active (2018–2023). It is exclusive to Ford and not shared with other manufacturers.
Aftermarket ECU tuning is common on the XTDB 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 Fiesta ST, expect ~7.2 L/100km (city) and ~5.1 L/100km (highway), or ~40 mpg UK combined. Real-world mixed driving typically returns 35–42 mpg UK, depending on driving style and GPF regeneration cycles.
Yes. The XTDB 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.
