The Ford UFDB is a 1,499 cc, inline‑three turbocharged petrol engine produced between 2018 and 2024. It features a DOHC 12‑valve layout, gasoline direct injection (GDI), and a single twin‑scroll turbocharger. In standard form it delivered 118 kW (160 PS) at 6,000 rpm with 250 Nm of torque at 1,600–4,000 rpm, providing responsive low — end thrust and improved fuel economy over larger four — cylinder units.
Fitted to models such as the Ford Focus Mk4, Puma, and Fiesta ST (2023+…
All production years (2018–2024) comply with Euro 6d emissions standards .
The Ford UFDB is a 1,499 cc inline‑three turbocharged petrol engine engineered for compact and subcompact vehicles (2018–2024). It combines gasoline direct injection with a twin‑scroll turbocharger to deliver brisk low-end torque and efficient urban driving. Designed to meet stringent Euro 6d emissions standards, it integrates a gasoline particulate filter and cooled EGR for regulatory compliance.

The Ford UFDB was used across Ford's C2 and B2E platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—integrated belt-driven starter-generator (BISG) in the Puma and Focus Mk4 mild-hybrid variants, and reinforced mounts in the Fiesta ST (2023+)—and from 2022 the HPFP and cam follower were revised to address wear concerns, creating minor service part distinctions. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The UFDB offers strong efficiency and performance but demands strict maintenance. HPFP wear is the top concern, especially with poor oil or fuel quality. Using Ford-specified 5W‑30 oil, adhering to 10,000 km intervals, and choosing TOP TIER fuel greatly improve reliability. Many well-maintained examples exceed 150,000 km without major issues.
Top issues include HPFP failure (P0087), GPF saturation from short trips, turbo wastegate rattle, and timing chain tensioner wear. These are documented in Ford TSB‑21‑0015 and related service updates. Most are preventable with proper maintenance and driving habits.
The UFDB powers the Ford Focus Mk4 (2018–2024), Puma (2019–2024), and Fiesta ST (2023–2024). The Focus and Puma use a mild-hybrid 48V system; the Fiesta ST is non-hybrid. No cross-manufacturer usage is documented.
Aftermarket ECU tuning is common on the UFDB 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 Hybrid: ~5.8 L/100km (49 mpg UK) combined. Real-world figures range from 45–55 mpg UK depending on driving style. Highway cruising can achieve ~4.9 L/100km (58 mpg UK), while city driving drops to ~6.5 L/100km (43 mpg UK).
Yes. The UFDB is an interference design. If the timing chain fails or jumps, pistons can contact open valves, causing catastrophic engine damage. Regular inspection of chain tensioners and oil quality is essential.
Ford specifies WSS‑M2C948‑B (5W‑30) synthetic oil—a low-SAPS, ACEA C2/C3 formulation. This protects the HPFP, turbo, and GPF. Never use non-approved oils, as they may accelerate HPFP wear or cause GPF clogging.
