The Ford IQDB is a 1,498 cc, inline — three 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 a compact turbocharger for improved low — end response. In standard tune, it delivers 103 kW (140 PS) and 240 Nm of torque, offering a balance of urban drivability and highway efficiency.
Fitted to models such as the Focus ST — Line, Puma ST, an…
Production years 2018–2023 meet Euro 6.2 standards .
The Ford IQDB is a 1,498 cc inline-three turbocharged petrol engine engineered for compact performance applications (2018–2023). It combines direct fuel injection with twin-independent variable cam timing (Ti-VCT) to deliver responsive low-end torque and smooth power delivery. Designed to meet Euro 6.2 standards, it balances spirited driving dynamics with regulated emissions performance.

The Ford IQDB was used across Ford's C2 platform with transverse mounting and shared with Volvo under engine supply agreements. This engine received platform-specific calibrations-shorter intake runners in the Fiesta and revised torque curves in the Puma-and from 2020 the facelifted Focus adopted the IQDB-T variant with enhanced cooling, 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 IQDB offers strong performance and efficiency, but early models (2018–2019) had turbo reliability concerns. Later revisions (post-2020) improved oil feed and cooling, making well-maintained examples robust. Regular servicing and using Ford-specified oil (5W-30 WSS-M2C947-A1) significantly improve longevity.
Key issues include turbocharger bearing wear (especially pre-2020), direct injector carbon buildup, cold-start timing chain rattle, and coolant leaks from the thermostat housing. These are documented in Ford service bulletins and addressed through updated parts and maintenance protocols.
The IQDB powers the Fiesta Mk8 (ST-3, ST-Line), Puma (ST-Line, Puma ST), and Focus Mk4 (ST-Line, Titanium) from 2018–2023. It is also used in the Volvo XC40 B4 (2020–2023) under a supply agreement. All variants meet Euro 6.2 emissions standards.
Aftermarket ECU tuning is common on the IQDB 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 ST-Line (103 kW), combined consumption is ~6.8 L/100km (~42 mpg UK). City driving may see 8.0 L/100km, while highway runs can achieve 5.8 L/100km (~49 mpg UK). Real-world figures depend on driving style, but expect 40–48 mpg (UK) on mixed routes for a well-maintained unit.
Yes. The IQDB is an interference engine. If the timing chain fails or skips, piston-to-valve contact will occur, resulting in severe internal damage. Immediate attention to cold-start rattles and adherence to maintenance schedules is essential to prevent costly repairs.
Ford specifies 5W-30 synthetic oil meeting WSS-M2C947-A1 specification. Change intervals should not exceed 12,000 km or 12 months. Proper oil ensures turbo bearing protection, reduces carbon buildup, and maintains timing chain lubrication under high thermal loads.
