The Ford CGBA is a 1,596 cc, inline — four petrol engine produced between 2010 and 2018. It forms part of Ford's EcoBoost engine family, featuring turbocharging and direct fuel injection to deliver responsive performance and improved fuel efficiency. This engine was designed with a focus on downsizing without sacrificing drivability, offering strong low — end torque for urban and highway use.
Fitted to models such as the Focus Mk3, C — MAX, and Mondeo Mk4, the CGBA was engin…
Production years 2010–2018 meet Euro 5 standards .
The Ford CGBA is a 1,596 cc inline-four turbocharged petrol engine engineered for compact and mid-size passenger vehicles (2010–2018). It combines direct fuel injection with turbocharging to deliver responsive acceleration and efficient fuel use. Designed to meet Euro 5 emissions standards, it balances everyday usability with performance-oriented driving characteristics.

The Ford CGBA was used across Ford's C1/D4 platforms with transverse mounting and no licensed external applications. This engine received platform-specific adaptations-shorter intake manifolds in the Focus and revised cooling routing in the Mondeo-and from 2015 the facelifted Focus Mk3.5 adopted revised engine management software, 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 CGBA offers strong performance and efficiency, but early models (2010-2014) had reliability concerns, particularly timing chain tensioner wear. Later revisions (post-2015) improved component durability, so well-maintained examples can be robust. Regular servicing with correct oil (5W-30 Ford WSS-M2C947-A1) and adherence to maintenance intervals greatly enhance longevity.
The most common issues are timing chain tensioner wear, intake valve coking due to direct injection, turbo wastegate sticking, and high-pressure fuel pump failure. These are documented in Ford service bulletins and verified through DVSA inspection data. Preventative maintenance significantly reduces risk.
The 1.6L EcoBoost CGBA engine was used in the Ford Focus Mk3 (2010-2018), C-MAX (2010-2018), and Mondeo Mk4 (2010-2015). It was not used in other brands or licensed externally. All applications met Euro 5 emissions standards.
Aftermarket ECU tuning is common on the CGBA 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 1.6 EcoBoost (110-118 kW), combined consumption is approximately 6.8 L/100km (~41 mpg UK). Highway driving can achieve ~5.5 L/100km (~51 mpg UK), while city use may reach 8.0 L/100km (~35 mpg UK). Real-world figures depend on driving style, but 38-45 mpg (UK) is typical for mixed conditions.
Yes. The CGBA is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in severe internal engine damage. This makes proper maintenance and immediate attention to any timing-related noises essential.
Ford specifies a 5W-30 synthetic oil meeting Ford WSS-M2C947-A1 specification. Using the correct oil is critical for turbocharger and timing chain lubrication. Oil changes should be performed every 15,000 km or annually to maintain reliability and prevent premature wear.
