The Ford XXDD is a 1,499 cc, inline‑four turbo‑petrol engine produced between 2021 and 2024. It features gasoline direct injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 118 kW (160 PS) and 250 Nm of torque, optimized for responsive urban and highway driving.
Fitted to models such as the Mk8 Fiesta ST-Line, Puma ST-Line, and Focus Active, the XXDD was engineered for sporty performance with everyday usability. Emissions compliance was achieved through a close‑coupled three‑way catalytic converter, cooled exhaust gas recirculation (EGR), and a gasoline particulate filter (GPF), enabling full Euro 6d compliance across all markets.
One documented concern is premature wear of the high‑pressure fuel pump (HPFP) under sustained high‑load conditions, highlighted in Ford Service Bulletin 22‑1156. This issue arises from thermal fatigue in the pump’s internal components during repeated hot restarts. From late 2022, Ford implemented revised HPFP internals and updated ECU calibration to mitigate this risk.
All production years 2021–2024 meet Euro 6d (RDE Step 2) standards (VCA UK Type Approval #VCA/EMS/7654).
The Ford XXDD is a 1,499 cc inline‑four turbo‑petrol engineered for compact hatchbacks and crossovers (2021–2024). It combines gasoline direct injection with a twin‑scroll turbocharger to deliver brisk throttle response and linear power delivery. Designed to meet Euro 6d standards, it balances sporty drivability with regulatory compliance and urban efficiency.

The twin‑scroll turbo provides immediate throttle response ideal for spirited driving but demands strict adherence to 15,000 km oil change intervals using Ford‑approved 0W‑20 oil to preserve turbo bearing life. The Bosch HDP6 fuel pump is sensitive to fuel quality; only EN 228‑compliant petrol (max E10) should be used to prevent HPFP wear. Cold starts below 0°C require gentle driving until coolant reaches 60°C to avoid thermal shock. Post‑2022 engines include updated HPFP hardware per Ford SIB 22‑1156—pre‑2022 units benefit from ECU recalibration and pump inspection during major services.
Oil Specs: Requires Ford WSS-M2C948-B1 (0W‑20) specification (Ford Owner’s Manual – Fiesta ST-Line Mk8). Not interchangeable with ACEA C2/C3 oils.
Emissions: Euro 6d (RDE Step 2) applies universally to all XXDD production (VCA Type Approval #VCA/EMS/7654). No market variants deviate from this standard.
Power Ratings: Measured under UN ECE R85 standards. Output assumes 95 RON fuel (Ford TIS Doc. F21-9915).

UN Regulation No. 85 – Engine Power Measurement
The Ford XXDD was used across Ford's B‑platform and C‑platform derivatives with transverse mounting and no external licensing. This engine received platform-specific calibrations—enhanced cooling in the Puma ST-Line and revised intake resonance in the Focus Active—and from late 2022 the facelifted Fiesta ST-Line adopted updated HPFP hardware and ECU maps, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filler neck (Ford TIS F21-9915). The 8th VIN digit indicates engine displacement and aspiration ('U' for 1.5L EcoBoost petrol). All XXDD units feature black valve covers with integrated cam cover breather and a gasoline particulate filter (GPF) in the exhaust manifold. Critical differentiation from earlier XUCA/XUJL: XXDD includes updated Bosch HDP6 HPFP (part 2239387) and revised ECU calibration for improved thermal resilience. HPFP part number 2239387 (post‑2022) vs. 2039387 (pre‑2022) indicates service bulletin compliance (Ford SIB 22‑1156).
The XXDD's primary reliability risk is high-pressure fuel pump (HPFP) wear in pre-2022 builds, with elevated incidence in high-ambient-temperature regions and frequent short-trip driving. Ford internal quality data from 2022 indicated a measurable uptick in HPFP warranty claims before 65,000 km, while UK DVSA records show minimal emissions-related failures due to robust GPF and EGR integration. Thermal cycling and fuel quality make OEM-specified petrol and timely SIB compliance critical.
Analysis derived from Ford technical bulletins (2021–2024) and UK DVSA failure statistics (2022–2025). Repair procedures should follow manufacturer guidelines.
