The Ford EYDF is a 1,999 cc, inline-four turbocharged petrol engine produced between 2018 and 2023. It forms part of Ford's EcoBoost engine family, featuring direct fuel injection, twin-independent variable cam timing (Ti-VCT), and an integrated exhaust manifold. In standard tune, it delivers 147 kW (200 PS) and 320 Nm of torque, enabling responsive performance in mid-size and performance-oriented applications.
Fitted to models including the Focus ST, Kuga ST-Line, and Edge, the EYDF was engineered for drivers seeking a balance of spirited performance and daily usability. It features a compacted graphite iron (CGI) block for durability under high boost pressure. Emissions compliance is achieved through a three-way catalytic converter and cooled exhaust gas recirculation (EGR), meeting Euro 6.2 standards across its production run.
One documented concern is intercooler piping detachment under high thermal cycling, highlighted in Ford Service Action 19S04. The issue arises from inadequate clamping force on charge-air hoses, leading to boost leaks and limp-mode activation. Ford issued a revised hose clamp kit and updated installation procedure for dealers to retrofit affected vehicles produced before June 2020.
Production years 2018–2023 meet Euro 6.2 standards (VCA UK Type Approval #VCA/EMS/5678).
The Ford EYDF is a 1,999 cc inline-four turbo-petrol engineered for performance and utility applications (2018–2023). It combines direct fuel injection with twin-independent variable cam timing to deliver strong mid-range torque and responsive throttle. Designed to meet Euro 6.2, it balances performance with emissions compliance.

The turbocharged design provides strong mid-range pull ideal for spirited driving but requires adherence to 15,000 km oil change intervals using Ford WSS-M2C949-A (5W-30) to prevent timing chain wear and turbo bearing degradation. The integrated exhaust manifold improves warm-up times but increases under-hood temperatures, necessitating periodic inspection of intercooler hoses. Owners should avoid excessive idling after hard driving to prevent turbo coking. The direct injection system is prone to low-speed pre-ignition (LSPI) under aggressive driving; use of premium fuel (RON 98) is recommended. Post-2020 models include revised hose clamps per Service Action 19S04 to mitigate boost leaks.
Oil Specs: Requires Ford WSS-M2C949-A (5W-30) specification (Ford SIB 19S04). Supersedes ACEA C2 requirements.
Emissions: Euro 6.2 certification applies to all production years (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. 147 kW output requires RON 98 fuel (Ford TIS Doc. A26015).

The Ford EYDF was used across Ford's C2 and CD4 platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake runners in the Focus ST and enhanced cooling in the Edge-and from 2021 the facelifted Kuga models adopted revised ECU calibrations for improved throttle response, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the transmission bellhousing (Ford IDS ENG456). The 8th VIN digit indicates engine type ('U' for 2.0L EcoBoost). Pre-2020 models have blue-topped fuel rails and black plastic intercooler piping; post-2020 units use revised silver clamps. Critical differentiation from non-ST 2.0L EcoBoost: EYDF features higher boost pressure (1.8 bar vs 1.4 bar) and reinforced pistons. Service parts require model-year verification—intercooler hoses before June 2020 are incompatible with updated clamping system (Ford SIB 19S04).
The EYDF's primary reliability risk is intercooler hose detachment on early builds, with elevated incidence in high-temperature environments. Internal Ford quality reports from 2019 indicated a significant number of pre-2020 units required hose re-securing before 80,000 km, while UK DVSA data shows a moderate rise in emissions-related faults linked to boost leaks. Aggressive driving and infrequent maintenance increase thermal stress, making hose inspection and correct clamping critical.
