The Ford UFBB is a 1,596 cc, inline‑four turbocharged petrol engine introduced in 2012 as part of Ford’s EcoBoost family. It features a DOHC 16‑valve layout, direct fuel injection, and a single twin — scroll turbocharger. In standard tune it produces 132 kW (180 PS) at 6,000 rpm and 240 Nm of torque from 1,750–4,500 rpm, offering brisk performance with improved fuel economy over larger naturally aspirated units.
Fitted to models including the Ford Focus ST Mk3, Focus RS (ear…

The Ford UFBB is a 1,596 cc inline‑four turbocharged petrol engine engineered for performance-oriented compact vehicles (2012–2018). It combines direct injection with a twin-scroll turbocharger to deliver strong mid-range torque and agile throttle response. Designed to meet Euro 5 emissions standards, it balances sporty character with regulatory compliance and real-world efficiency.

The Ford UFBB was used across Ford's C1 and CD4 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts in the Focus ST for track use and unique exhaust manifolds in the Mondeo—and from 2015 minor ECU updates were introduced for emissions stability, creating minor calibration 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The UFBB is generally robust when maintained correctly. Early units (2012–2014) had HPFP concerns addressed via updated service kits. Using the correct 5W‑30 oil and allowing proper warm-up before hard driving significantly improves longevity. The timing chain system is designed for life, but oil quality remains critical.
Main issues include high-pressure fuel pump failure, turbo wastegate rattle, intake valve carbon buildup, and plastic thermostat housing leaks. These are documented in Ford bulletins FEB‑14‑06 and SIB 04‑13‑09. Most are preventable with proper maintenance and driving habits.
The UFBB powered early Focus ST Mk3 prototypes, pre-facelift Mondeo Mk4 (2012–2014), and S-MAX (2012–2014), all with 2.0L EcoBoost branding. It was later superseded by higher-output variants in production Focus ST models.
Aftermarket ECU tuning is common on the UFBB 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 Mondeo 2.0 EcoBoost 200 PS, expect 7.8–8.5 L/100km (36–33 mpg UK) combined. Real-world figures vary with driving style, but the engine performs best on mixed or highway cycles due to turbo efficiency.
Yes. The UFBB is an interference engine. If the timing chain fails (though rare), pistons will contact open valves, causing severe internal damage. However, the chain is designed for lifetime use with proper oil maintenance.
Ford specifies WSS-M2C945-A (SAE 5W‑30 full synthetic) oil. This formulation ensures HPFP cam follower protection and turbo longevity. Substituting with non-approved oils may accelerate HPFP wear and void warranty.
