The Ford M8DA is a 1,998 cc, inline — four naturally aspirated petrol engine produced between 2020 and 2023. It forms part of Ford's Sigma engine family, featuring port fuel injection, dual independent variable cam timing (Ti — VCT), and a lightweight aluminium block. Designed for durability and ease of maintenance, it produces 103 kW (140 PS) and 188 Nm of torque, with linear power delivery ideal for daily driving.
Fitted to models such as the Focus Titanium, Kuga Trend, and…
Production years 2020–2023 meet Euro 6.2 standards .
The Ford M8DA is a 1,998 cc inline-four naturally aspirated petrol engine engineered for mainstream applications (2020–2023). It combines port fuel injection with twin-independent variable cam timing (Ti-VCT) to deliver smooth, predictable performance and long-term reliability. Designed to meet Euro 6.2 standards, it prioritizes durability and serviceability in compact and mid-size Ford vehicles.

The Ford M8DA was used across Ford's C2 and C3 platforms with transverse mounting. This engine received platform-specific adaptations-longer intake runners in the Kuga and revised cooling layouts in the EcoSport-and from 2022 the facelifted Focus adopted the M8DA with enhanced engine mounts, 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 M8DA offers predictable performance and mechanical simplicity, but early models (2020–2021) had reliability concerns, particularly intake manifold runner flap failures. Later revisions (post-2022) improved durability with reinforced components. Well-maintained engines with regular oil changes and highway runs can exceed 180,000 km. Using correct oil (5W-30 WSS-M2C949-B) is essential for longevity.
The most common issues are intake manifold runner flap failure, intake valve carbon buildup, timing chain tensioner wear, and EGR valve coking. These are documented in Ford service bulletins, particularly SIB 21S08 for the intake manifold issue. Regular maintenance significantly reduces the risk of major repairs.
The M8DA engine is used in the Ford Focus (2020–2023), Kuga (2020–2023), and EcoSport (2020–2023) across Titanium, Trend, and Active trims. It serves as a naturally aspirated alternative to EcoBoost variants and is tuned for dependable driving in mainstream Ford models. All models meet Euro 6.2 emissions standards.
Aftermarket ECU tuning is common on the M8DA 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 real-world driving, the M8DA achieves approximately 7.8–8.6 L/100km (36–34 mpg UK) in mixed conditions. Highway efficiency improves to ~6.9 L/100km (~41 mpg UK). Fuel economy depends heavily on driving style and transmission type (manual vs. automatic), with automatic variants typically consuming more.
Yes. The M8DA is an interference engine, meaning that if the timing chain fails or jumps, the pistons can collide with open valves, causing severe internal damage. This makes timely inspection and replacement of the timing system critical, especially if rattle or misfire symptoms appear.
Ford specifies WSS-M2C949-B (5W-30) synthetic oil for the M8DA engine. This formulation is designed for naturally aspirated petrol engines and protects the timing chain and valve train. Oil should be changed every 20,000 km or annually to maintain engine health and prevent carbon buildup.
