The Ford D4FA is a 1,388 cc, inline — four naturally aspirated petrol engine produced between 2015 and 2020. It forms part of Ford's Dragon engine family, designed for compact vehicle applications with a focus on fuel efficiency and low — cost ownership. Featuring dual independent variable cam timing (Ti — VCT), port fuel injection, and a lightweight aluminium block, it delivers smooth, predictable power delivery suitable for urban and commuter driving.

The Ford D4FA is a 1,388 cc inline-four naturally aspirated petrol engine engineered for compact vehicles (2015–2020). It combines port fuel injection with dual Ti-VCT to deliver smooth power delivery and strong low-end response. Designed to meet Euro 6b standards, it balances fuel economy with emissions compliance and everyday drivability.

The Ford D4FA was used across Ford's B298, C519, and C346 platforms with transverse mounting. This engine received platform-specific tuning—slightly revised torque curve in the Puma and cold-start calibration in the Focus—and from 2018, the updated Fiesta adopted a revised intake manifold, creating 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 D4FA is generally reliable with strong build quality and straightforward maintenance. Early models (2015–2018) had intake resonance issues, but post-2018 revisions resolved this. No major mechanical flaws are documented, and with regular servicing using correct oil (WSS-M2C913-D), these engines typically exceed 150,000 km without major repairs.
Key issues include intake resonance drone (pre-2018), timing chain tensioner wear, knock sensor false triggering with low-octane fuel, and exhaust manifold cracking due to thermal stress. These are documented in Ford service bulletins. Using correct fuel and oil significantly reduces risk.
The D4FA is used in the Fiesta (B298, 2017–2020), Focus (C519, 2018–2020), and Puma (C346, 2019–2020). Each application has minor calibration differences. It is not used in EcoBoost or diesel variants and was phased out in favour of the 1.0L EcoBoost in 2021.
Limited potential. As a naturally aspirated engine with port injection, ECU remapping yields minimal gains (typically +5–10 kW). Performance improvements are better achieved through intake/exhaust modifications, but gains are modest. The engine is not designed for forced induction upgrades.
In the Fiesta 1.4, expect ~7.2 L/100km (city) and ~5.1 L/100km (highway), or ~39 mpg UK combined. In the Focus, figures are ~7.6 L/100km combined. Real-world consumption depends on driving style, but aggressive use can exceed 9 L/100km.
Yes. The D4FA is an interference engine. If the timing chain fails, pistons can contact valves, causing severe internal damage. Chain and tensioner maintenance is critical—any rattling should be investigated immediately to prevent costly repairs.
Ford specifies SAE 5W-30 meeting WSS-M2C913-D spec. Use only Ford-approved or equivalent synthetic oil designed for naturally aspirated Ti-VCT engines. Change every 15,000 km or annually to protect the timing chain and camshafts.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
