The Ford HXDB is a 1,998 cc, inline — four turbocharged petrol engine produced between 2019 and 2024. It features direct fuel injection, twin — independent variable cam timing (Ti — VCT), and a low — inertia turbocharger, delivering 184 kW (250 PS) and 373 Nm of torque. This EcoBoost unit enables strong mid — range performance ideal for performance — oriented driving and highway overtaking.
Fitted to models such as the Focus ST, Puma ST, and Kuga ST — Line, the HXDB was engineere…
All production years (2019–2024) meet Euro 6d emissions standards .
The Ford HXDB is a 1,998 cc inline-four turbocharged petrol engine engineered for high-performance compact and subcompact vehicles (2019–2024). It combines direct injection with Ti-VCT and a compact turbocharger to deliver aggressive throttle response and strong torque output. Designed to meet Euro 6d standards, it balances sporty character with regulated emissions performance.

The Ford HXDB was used across Ford's C2 platform with transverse mounting and shared architecture with performance variants of the CD6 platform. This engine received platform-specific adaptations-shorter intake manifolds in the Focus ST and revised cooling routing in the Puma ST-and from 2022 the facelifted Kuga adopted the HXDB with updated ECU mapping and actuator hardware, 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 HXDB is generally robust when maintained properly, but pre-2022 models have a known intake actuator issue. Later revisions (post-2022) show improved reliability. Regular oil changes with Ford WSS-M2C949-B (5W-30) and use of quality fuel are essential. Well-maintained units can exceed 200,000 km without major issues.
Key issues include intake manifold runner flap actuator degradation, high-pressure fuel pump wear, intake carbon buildup, and timing chain tensioner degradation. These are documented in Ford SIBs and field reports. Actuator problems are most frequent in city-driven vehicles, while fuel pump wear correlates with low tank levels and poor fuel quality.
The HXDB powers the Focus ST (2019–2024), Puma ST (2019–2024), and Kuga (2020–2024) in 2.0T configurations. All models require Euro 6-compliant servicing and specific calibration. No cross-manufacturer applications are documented.
Aftermarket ECU tuning is common on the HXDB 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, combined consumption is ~8.5 L/100 km (~33.2 mpg UK). Real-world figures vary: 28–33 mpg UK in mixed driving, lower in spirited use. Puma ST and Kuga models average 30–36 mpg UK. Fuel economy depends heavily on driving style and condition of EGR/intake systems.
Yes. The HXDB is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal damage. Immediate attention to any timing-related noises or faults is critical to avoid costly repairs.
Ford specifies WSS-M2C949-B (5W-30) synthetic oil. This low-SAPS formulation ensures compatibility with turbo, GPF (if equipped), and timing components. Change every 15,000 km or 12 months. Using non-approved oil increases risk of HPFP and turbo failure.
