The Ford MUDA is a 999 cc, inline-three naturally aspirated petrol engine produced between 2015 and 2018. It features multi-point fuel injection (MPFI), dual overhead camshafts (DOHC), and a compact valvetrain designed for urban efficiency. Delivering 50 kW (68 PS) and 99 Nm of torque, it prioritizes fuel economy and low maintenance cost over performance, making it ideal for city driving and entry-level applications.
Fitted to models such as the Fiesta Mk7 and B-MAX, the MUDA engine was engineered for affordability and emissions compliance in European B-segment vehicles. It meets Euro 6b standards through precise air-fuel metering and a close-coupled catalytic converter, with no gasoline particulate filter (GPF) required. The engine’s simplicity supports extended service intervals and low ownership costs, appealing to fleet and first-time buyers.
One documented concern is premature camshaft wear in high-mileage units, noted in Ford Service Information Bulletin 17M08. This issue is linked to marginal oil pressure at the camshaft journals under sustained low-RPM operation. From mid-2016, revised camshaft bearing clearances and updated oil pump rotor profiles were introduced to improve lubrication reliability.
All production units comply with Euro 6b emissions standards (VCA UK Type Approval #VCA/EMS/4321).
The Ford MUDA is a 999 cc inline-three naturally aspirated petrol engine engineered for compact urban applications (2015–2018). It combines MPFI with DOHC valvetrain architecture to deliver reliable, low-cost operation. Designed to meet Euro 6b standards, it emphasizes fuel efficiency and serviceability over performance, targeting cost-conscious consumers and fleet operators.

The naturally aspirated inline-3 provides smooth, predictable delivery ideal for city commuting but requires adherence to 20,000 km oil service intervals to prevent camshaft wear. Ford WSS-M2C913-C (5W-20) oil is essential due to its low viscosity and protection of the high-load camshaft bearings. Avoid prolonged idling and low-RPM lugging to maintain oil pressure and bearing longevity. The absence of GPF or turbocharger reduces maintenance complexity, but spark plug and injector service remains critical for emissions compliance. Post-2016 models feature improved oil pump design; pre-2016 units benefit from the updated rotor upgrade per Ford SIB 17 08 05. MPFI system is tolerant of lower fuel grades; minimum RON 91 is acceptable for standard operation.
Oil Specs: Requires Ford WSS-M2C913-C (5W-20) specification (Ford SIB 17 08 05). Optimized for fuel economy and cold-start performance.
Emissions: Certified to Euro 6b standards across entire production run (VCA Type Approval #VCA/EMS/4321). No GPF required.
Power Ratings: Measured under SAE J1349 standards. Peak output achieved at 6,000 rpm with standard calibration.

The Ford MUDA was used across Ford's C1 platform with transverse mounting and no hybrid integration. This engine received platform-specific adaptations-shorter accessory belts in the B-MAX and revised intake routing in the Fiesta-and from mid-2016 the facelifted Fiesta models adopted the MUDA-II variant with updated camshaft profiles, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the left-side engine block near the transmission bellhousing (Ford TIS F18800). The 8th VIN digit indicates engine family ('H' for MUDA series). Pre-2016 models have white valve covers with silver timing covers; post-2016 units use black valve covers. Critical differentiation from MUDA-II: Original MUDA uses Bosch MD1CS018 ECU with 64-pin connector, while MUDA-II uses MD1CS022 with 72-pin. Service parts require production date verification - camshafts for engines before 07/2016 are incompatible with later units due to journal diameter changes (Ford SIB 17 08 05).
The MUDA's primary reliability risk is camshaft wear on early builds, with elevated incidence in high-mileage urban use. Internal Ford quality reports from 2017 indicated a notable share of pre-2016 engines requiring camshaft replacement beyond 150,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to aging MPFI components in city-driven vehicles. Prolonged idling and low-RPM operation increase bearing stress, making oil interval adherence and driving pattern critical.
