The Ford XMJB is a 1,999 cc, inline‑four turbocharged petrol engine produced between 2019 and 2024. It features a DOHC 16‑valve layout, gasoline direct injection (GDI), and a single twin‑scroll turbocharger. In standard form it delivered 177 kW (240 PS) at 5,500 rpm with 370 Nm of torque at 1,500–4,000 rpm, providing strong mid-range thrust and responsive performance across a broad rev range.
Fitted to models such as the Ford Focus ST (Mk4), Focus Active, and Kuga ST-Line, the XMJB was engineered for sporty driving dynamics while meeting stringent Euro 6d emissions standards. Compliance was achieved through cooled exhaust gas recirculation (EGR), a gasoline particulate filter (GPF), and precise GDI control strategies validated under real-driving emissions (RDE) protocols.
One documented concern is high-pressure fuel pump (HPFP) cam follower wear leading to fuel rail pressure instability, highlighted in Ford Technical Service Bulletin TSB‑20‑0021. This issue stems from marginal lubrication under high thermal loads, particularly when oil change intervals exceed 10,000 km or non-approved oils are used. Ford introduced a revised HPFP follower kit from 2021 onward.
All production years (2019–2024) comply with Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/FORD-XMJB-2019).
The Ford XMJB is a 1,999 cc inline‑four turbocharged petrol engine engineered for performance-oriented compact and crossover vehicles (2019–2024). It combines gasoline direct injection with a twin‑scroll turbocharger to deliver strong low-end and mid-range torque with crisp throttle response. Designed to meet Euro 6d emissions standards under real-driving conditions, it integrates a gasoline particulate filter and cooled EGR for full regulatory compliance.

The twin-scroll turbo and GDI system deliver strong, linear power ideal for spirited driving but require strict adherence to 10,000 km oil change intervals using Ford WSS‑M2C948‑B (5W‑30) to protect the HPFP cam follower and timing chain. Carbon buildup on intake valves—common in GDI engines—is mitigated by occasional highway driving that enables passive GPF regeneration. Use of TOP TIER gasoline is strongly recommended to reduce injector and HPFP wear. Revised HPFP kits (from 2021) should be installed if P0087 or hard-start symptoms appear. Avoid prolonged idling or short trips to prevent GPF saturation.
Oil Specs: Requires Ford WSS‑M2C948‑B (5W‑30) synthetic oil (Ford LB‑XMJB‑2019). Equivalent to ACEA C2/C3 with low-SAPS formulation.
Emissions: Full Euro 6d compliance confirmed for all model years via VCA Type Approval #VCA/EMS/FORD-XMJB-2019.

The Ford XMJB was used across Ford's C2 platform with transverse mounting and no external licensing. This engine received platform-specific adaptations—sport-tuned mounts and exhaust in the Focus ST, and enhanced cooling in the Kuga ST-Line—and from 2021 the HPFP cam follower was revised to address wear concerns, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block near the timing cover (Ford TIS Fig. 1999GDI‑02). The full code reads 'XMJB' followed by a serial number. The Focus ST features a unique downpipe and intercooler; the Kuga uses a reinforced oil pan and additional underbody shielding. ECU part numbers begin with '20Cxxx'—verify via Ford IDS diagnostics. Do not confuse with the lower-output 2.0L EcoBoost (code M2DA), which lacks the twin-scroll turbo and produces 137 kW.
The XMJB's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear due to marginal lubrication under high thermal stress, with elevated incidence in vehicles subjected to extended oil change intervals or non-compliant oils. Ford internal field reports from 2020 noted a measurable rate of P0087 fuel rail pressure faults after 80,000 km in non-compliant maintenance cases, while UK DVSA MOT data shows GPF-related warning lights as a secondary concern in high-idle urban use. Adherence to oil specs and driving patterns makes HPFP longevity critical.
