The Ford DHD is a 2,261 cc, inline — four turbocharged petrol engine produced between 2021 and 2023. It is part of Ford’s EcoBoost Gen — 4 engine family, featuring high — pressure direct injection, twin — scroll turbocharging, and advanced thermal management. Delivering 210 kW (286 PS) and 440 Nm of torque, it is engineered for high — performance applications in performance SUVs and sport — oriented variants.
Fitted to models including the Ford Puma ST, Focus ST, and Kuga ST, t…
All production units (2021–2023) comply with Euro 6d-Full .
The Ford DHD is a 2,261 cc inline-four turbocharged petrol engine designed for performance-oriented platforms (2021–2023). It combines dual injection (direct + port) with a compact twin-scroll turbocharger to deliver strong low-end torque and high-rpm power. Engineered to meet Euro 6d-Full standards, it integrates advanced thermal management and, in select models, a 48V mild hybrid system for enhanced drivability.

The Ford DHD was used across Ford's C2 and CD4 platforms with transverse mounting and integrated performance tuning. This engine received model-specific calibrations—aggressive throttle mapping in the Focus ST and revised torque delivery in the Puma ST—and from late 2022, updated HPFP cooling and calibration were implemented, 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.
The DHD's primary reliability risk is premature high-pressure fuel pump (HPFP) wear, with higher incidence in vehicles operated on regular unleaded or subjected to frequent short trips. Ford internal service reports from 2023 indicated a notable number of pre-late-2022 units required HPFP replacement before 80,000 km, while VCA data shows increased fuel system-related faults in urban environments. Low exhaust temperatures and poor fuel quality promote thermal stress and injector coking, making adherence to service intervals and use of premium fuel critical for system longevity.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DHD engine is generally reliable when maintained properly, though pre-late-2022 models have a known issue with high-pressure fuel pump wear. Later models (late-2022+) benefit from updated calibration and cooling. Regular oil changes, use of Ford-specified 5W-30 oil, and consistent use of 98 RON fuel help prevent fuel system stress and ensure longevity beyond 150,000 km.
Key issues include high-pressure fuel pump wear (especially pre-late-2022), intake and EGR carbon buildup due to direct injection, and timing chain tensioner wear. Mild hybrid variants may experience 48V system faults. These are documented in Ford Service Action 22T04 and technical bulletins.
The DHD engine is used in the Ford Puma ST (2021–2023), Focus ST (2021–2023), and Kuga ST (2022–2023, mild hybrid). It is specific to high-performance EcoBoost applications with dual injection, twin-scroll turbo, and Euro 6d-Full compliance.
Aftermarket ECU tuning is common on the DHD 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 Ford Focus ST, combined consumption is ~8.5 L/100km (~33 mpg UK). Real-world figures vary: city driving may see 10.0 L/100km, while highway runs can achieve 7.0 L/100km. The 48V system in Kuga ST improves urban efficiency by up to 6%.
Yes, the DHD is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause severe internal damage. Immediate attention to timing-related noises is essential to avoid costly repairs.
Ford specifies WSS-M2C949-C (5W-30) synthetic oil. Change intervals are 15,000 km or 12 months. Using correct oil ensures proper turbo and timing chain lubrication, reducing wear and carbon formation in direct-injection engines.
