The Ford T7MB is a 1,499 cc, inline‑three turbo‑petrol engine produced between 2018 and 2023. It features direct fuel injection, a single twin — scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 92 kW (125 PS) and 240 Nm of torque, optimized for urban efficiency and compact packaging.
Fitted to models such as the Fiesta, Focus, and Puma, the T7MB was engineered for responsive drivability and low CO₂ emissions in city environments. Emiss…
All production years (2018–2023) meet Euro 6d-TEMP (2018–2020) or Euro 6d (2021–2023) standards .
The Ford T7MB is a 1,499 cc inline‑three turbo‑petrol engineered for B‑Car and C‑Car platforms (2018–2023). It combines direct injection with a twin‑scroll turbocharger to deliver brisk low-end response and urban efficiency. Designed to meet Euro 6d-TEMP/Euro 6d standards, it balances compact design with everyday drivability.

The Ford T7MB was used across Ford's B‑Car and C‑Car platforms with transverse mounting. This engine received platform-specific calibrations—revised cooling in the Puma for tropical climates and unique ECU maps in the Focus—and from 2021 the Fiesta adopted updated engine mounts for NVH refinement, creating minor ECU and harness 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 T7MB is generally robust when maintained properly. Early models (2018–2020) had HPFP concerns, but post-2020 revisions improved durability. Using 95 RON fuel, adhering to oil specs (0W-20 WSS-M2C949-A1), and occasional highway driving for GPF regeneration greatly enhance longevity.
Top issues include high-pressure fuel pump wear (pre-2020), GPF clogging from short trips, intake valve carbon buildup due to direct injection, and turbo wastegate rattle. These are documented in Ford service bulletins 19M02 and T21‑10.
The T7MB powers the Fiesta (Mk8, 2018–2023), Focus (Mk4, 2018–2023), and Puma (2019–2023). All are 1.5L EcoBoost 125 PS variants without cylinder deactivation.
Aftermarket ECU tuning is common on the T7MB 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 Fiesta, expect ~6.5 L/100km (city) and ~4.7 L/100km (highway), or ~47 mpg UK combined. Real-world mixed driving typically returns 42–49 mpg UK. Economy suffers if short trips dominate due to incomplete GPF regeneration.
Yes. The T7MB is an interference engine. If the timing chain fails (rare but possible), valve-to-piston contact can cause catastrophic damage. Fortunately, the chain is front-mounted and designed for life-of-engine service under proper maintenance.
Ford specifies SAE 0W‑20 oil meeting WSS‑M2C949‑A1 standard. This low-viscosity oil is critical for fuel economy, GPF protection, and emissions compliance. Never use older Ford oil specs (e.g., 5W‑30) as they may increase ash and damage the GPF.
