The Ford CSDB is a 1,498 cc, inline — three turbocharged petrol engine produced between 2018 and 2023. It forms part of Ford's EcoBoost engine family, featuring direct fuel injection, dual independent camshaft timing (Ti — VCT), and a compact turbocharger for improved low — end responsiveness. In standard tune, it delivers 103 kW (140 PS), with peak torque of 240 Nm available from 1,600 rpm, enabling strong urban drivability and highway overtaking capability.

Production years 2018–2020 meet Euro 6d-TEMP standards; 2021–2023 models comply with full Euro 6d .
The Ford CSDB is a 1,498 cc inline-three turbocharged petrol engine engineered for compact and subcompact models (2018-2023). It combines direct fuel injection with twin-independent cam phasing to deliver responsive low-RPM torque and smooth power delivery. Designed to meet Euro 6d emissions standards, it balances performance, efficiency, and regulatory compliance.

The Ford CSDB was used across Ford's C2 platform with transverse mounting and shared with Volvo under engine co-development agreements. This engine received platform-specific adaptations-shorter intake manifolds in the Puma and revised torque mounts in the Focus-and from 2021 the facelifted Fiesta ST-Line models adopted the CSDB with enhanced cooling, creating interchange limits. Partnerships enabled Volvo's B3 units to use Ford's turbo and injection hardware. 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 CSDB is generally reliable when maintained properly, though pre-2020 models are prone to intake carbon buildup and PCV issues. Later revisions (post-2020) feature improved PCV calibration, reducing intake fouling. Regular oil changes with Ford WSS-M2C947-B1 (5W-30) and periodic induction cleaning greatly enhance longevity. Well-maintained engines typically exceed 150,000 km without major repairs.
The most documented issues are intake valve carbon buildup, turbo VNT actuator sticking, timing chain tensioner wear, and coolant leaks from the thermostat housing. These are supported by Ford service actions and dealer repair data. PCV system degradation and direct-injection knock under low-octane fuel are also reported. All are addressable with OEM-recommended maintenance.
The CSDB 1.5L EcoBoost engine is used in the Focus (Mk4, 2018–2023), Fiesta (Mk8, 2018–2023), and Puma (2019–2023). It powers the 140 PS petrol variants across these lines. Volvo also uses a derivative (B3) in the XC40 (2020–2023), sharing core turbo and injection components under the Ford-Volvo engine agreement.
Aftermarket ECU tuning is common on the CSDB 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 combined driving, the CSDB achieves approximately 6.8 L/100km (41.7 mpg UK) in the Focus and 6.5 L/100km (43.5 mpg UK) in the lighter Fiesta. Highway consumption drops to ~5.2 L/100km (54.3 mpg UK). Real-world figures vary; aggressive driving or frequent short trips reduce efficiency. Use of RON 95+ fuel optimises combustion and economy.
Yes, the CSDB is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in bent valves or piston damage. This makes timely inspection and replacement of the tensioner and guides critical. Any rattling at cold start should prompt immediate inspection to prevent catastrophic failure.
Ford specifies WSS-M2C947-B1 (5W-30) synthetic oil, designed for turbocharged direct-injection engines. This oil resists LSPI and provides optimal chain and turbo protection. Change intervals should not exceed 15,000 km or 12 months. Using non-compliant oil increases risk of timing wear and carbon buildup.
