The Ford CGBB is a 1,596 cc, inline — three turbocharged petrol engine produced between 2010 and 2018. It forms part of Ford's EcoBoost engine family, featuring direct fuel injection, twin — independent variable cam timing (Ti — VCT), and an intercooled turbocharger. In standard tune it delivers 138 kW (187 PS) and 240 Nm of torque, providing a balance of responsive performance and fuel efficiency for compact and mid — size applications.
Fitted to models such as the Focus ST,…
Production years 2010–2018 meet Euro 5 standards .
The Ford CGBB is a 1,596 cc inline-three turbocharged petrol engineered for performance-oriented compact models (2010-2018). It combines direct fuel injection with twin-independent variable cam timing (Ti-VCT) and an intercooled turbocharger to deliver responsive throttle characteristics and strong mid-range torque. Designed to meet Euro 5 standards, it balances sporty performance with improved fuel efficiency.

The Ford CGBB was used across Ford's C1/C2 platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Fiesta and reinforced engine mounts in the Focus ST-and from 2015 the facelifted Focus Mk3 models adopted revised turbo cooling protocols, 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.
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 CGBB delivers strong performance and efficiency, but early models (2010-2014) had turbocharger reliability concerns. Later revisions (post-2015) improved oil feed design, so well-maintained examples can exceed 200,000 km. Regular servicing and using Ford WSS-M2C946-B oil (5W-30) are essential for longevity.
The most common issues are turbocharger bearing wear, high-pressure fuel pump (HDEV5) failure, EGR/intake coking, and timing chain tensioner rattle. These are documented in Ford service bulletins, particularly SIB 15B07 and SIB 15 03 08, and are often linked to maintenance neglect.
The CGBB was used in performance and mainstream Ford models including the Focus ST (2010-2018), Fiesta ST (2013-2017), and C-MAX (2010-2015). It was exclusively available in European and North American markets with transverse front-wheel-drive layouts.
Aftermarket ECU tuning is common on the CGBB 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 Focus ST (138 kW), combined consumption is ~7.2 L/100 km (~39 mpg UK). Highway driving can achieve ~6.0 L/100 km (~47 mpg UK). Real-world figures vary with driving style, but expect 35-45 mpg UK in mixed conditions. Use of RON 95+ fuel is required for optimal efficiency.
Yes. The CGBB is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal engine damage. Chain maintenance and oil health are critical; any tensioner noise should be investigated immediately.
Ford specifies WSS-M2C946-B (5W-30) synthetic oil. This low-SAPS formulation is essential for turbocharger and HDEV5 fuel pump protection. Oil changes should occur every 15,000 km or annually, with strict adherence to specification to prevent premature wear.
