The Ford F57D is a 1,999 cc, inline — four naturally aspirated petrol engine produced between 2015 and 2020. It belongs to Ford’s Sigma engine family, featuring dual independent variable cam timing (Ti — VCT) and an aluminium block and head. In standard tune it delivered 103 kW (140 PS) and 190 Nm of torque, primarily for European compact and mid — size applications.
Fitted to models such as the Ford Focus (C346), Mondeo (CD391), and C — Max (C328), the F57D was engineered for fue…
Production years 2015–2017 meet Euro 6b; 2018–2020 models comply with Euro 6c .
The Ford F57D is a 1,999 cc inline-four petrol engine engineered for compact and mid-size passenger vehicles (2015–2020). It combines Ti-VCT variable valve timing with port fuel injection to deliver balanced efficiency and drivability. Designed to meet Euro 6b and 6c emissions standards, it prioritises low ownership costs and smooth operation.

The Ford F57D was used across Ford's C2 and CD391 platforms with transverse mounting. This engine received platform-specific adaptations-revised intake manifolds in the Mondeo and modified cooling in the Focus ST-Line-and from 2018 the C-Max facelift adopted revised EGR calibration, 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 F57D is generally durable with smooth operation, though pre-2018 models are prone to intake valve carbon buildup in urban driving. Later revisions with updated EGR calibration improved resistance to deposits. Well-maintained engines with regular induction cleaning and oil changes using WSS-M2C946-B (5W-30) can exceed 180,000 km without major issues.
Primary issues include intake valve carbon buildup, EGR valve clogging, valve cover oil leaks, and throttle body malfunctions. These are documented in Ford service bulletins, with carbon-related issues most prevalent in stop-start driving. Most are preventable with proper maintenance and adherence to service intervals.
The F57D was used in the Ford Focus (2015–2020), Mondeo (2015–2020), C-Max (2015–2020), and Grand C-Max (2015–2020). It was offered primarily in European markets, meeting Euro 6b and 6c emissions standards depending on model year.
Limited potential. As a naturally aspirated engine with PFI, the F57D responds modestly to ECU tuning, typically gaining +8–12 kW. Significant gains require forced induction or hybridization. Most owners focus on maintenance and drivability rather than performance tuning for this engine.
Moderate. In a 2017 Focus, combined consumption is ~7.2 L/100km (39 mpg UK), with city driving ~8.5 L/100km and highway ~6.3 L/100km. Real-world figures vary by driving style, but expect 35–40 mpg (UK) on mixed routes. Efficiency is lower than EcoBoost turbocharged variants.
Yes. The F57D is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in bent valves or damaged pistons. Immediate attention to timing chain noise is essential to prevent catastrophic engine damage.
Ford specifies WSS-M2C946-B (5W-30) synthetic blend or full synthetic oil. Change intervals should not exceed 15,000 km or one year, whichever comes first. Using the correct oil is critical for valve train longevity and overall engine reliability.
