The Ford T1DB is a 1,499 cc, inline‑three turbocharged petrol engine produced between 2018 and 2024. It features direct fuel injection, a twin — scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 110 kW (150 PS) and 240 Nm of torque, with responsive low‑end performance suited for urban and mixed driving.
Fitted to models such as the Ford Focus (Mk4), Puma, and EcoSport, the T1DB was engineered for efficiency and drivability in compact veh…
All production years (2018–2024) meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/6789).
The Ford T1DB is a 1,499 cc inline‑three turbocharged petrol engine engineered for compact hatchbacks and crossovers (2018–2024). It combines direct injection with a twin‑scroll turbocharger to deliver brisk low‑end torque and smooth power delivery. Designed to meet Euro 6d standards, it balances everyday responsiveness with urban efficiency.

The Ford T1DB was used across Ford's C2 and B2E platforms with transverse mounting. This engine received platform-specific adaptations—revised cooling ducting in the Puma and stiffer engine mounts in the EcoSport—and from 2021 the Focus adopted updated EGR calibration to mitigate carbon buildup, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The T1DB's primary reliability risk is intake valve carbon fouling due to direct-injection-only design, with elevated incidence in urban-driven vehicles. Ford internal data (2023) showed a measurable increase in intake cleaning requests for pre-2021 builds, while UK DVSA records indicate minimal GPF-related MOT failures thanks to robust regeneration logic. Frequent short trips without highway driving accelerate deposit formation, making driving pattern and maintenance critical.
Analysis derived from Ford technical bulletins (2020–2024) and UK DVSA failure statistics (2020–2024). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The T1DB is generally dependable with proper maintenance. Its main weakness is intake valve carbon buildup in pre-2021 models due to direct injection only. Using correct 0W-20 oil, avoiding constant short trips, and periodic intake cleaning greatly improve longevity. Most owners report smooth operation when driven with occasional highway use.
The top issues are carbon buildup on intake valves (especially pre-2021), GPF regeneration faults from short-trip driving, and occasional turbo wastegate rattle. Minor oil dilution may occur in very cold climates with frequent cold starts. These are documented in Ford TSBs and are manageable with OEM-recommended practices.
The T1DB powers the fourth-gen Ford Focus (1.5 EcoBoost 150 PS), Ford Puma (125 PS hybrid and non-hybrid), and facelifted EcoSport (2020–2023, 125 PS). All meet Euro 6d and feature GPF, twin-scroll turbo, and DOHC inline-3 architecture.
Yes. Stage 1 remaps typically yield +15–25 kW safely on stock hardware. The engine shares architecture with the higher-output STJB, so internals are robust. Always use 98 RON fuel and avoid aggressive tuning on high-mileage engines with known carbon buildup.
In a Focus 1.5 EcoBoost 150 PS, expect ~6.8 L/100km (city) and ~4.9 L/100km (highway), or ~47 mpg UK combined. Puma hybrids achieve ~4.6 L/100km. Real-world figures vary, but 45–50 mpg (UK) is typical for mixed driving with regular highway use.
Yes. The T1DB is an interference engine. If the timing chain fails (rare but possible), valve-to-piston contact can cause catastrophic damage. However, the chain is front-mounted and designed for life-of-engine service under normal conditions.
Ford specifies 0W-20 synthetic oil meeting WSS-M2C949-A. This low-viscosity oil is essential for turbo cooling, GPF protection, and fuel system longevity. Never substitute with older 5W-30 specs—doing so may void warranty and increase wear.
