The Ford YUDA is a 1,596 cc, inline‑four turbocharged petrol engine produced between 2012 and 2018. It features a dual overhead camshaft (DOHC) layout with 16 valves and direct fuel injection. In standard form it delivered 132 kW (180 PS) and 240 Nm of torque, offering strong mid‑range response and brisk urban acceleration.
Fitted to models such as the Ford Focus ST Mk3, Focus RS (early development mules), and select European-market Mondeo variants, the YUDA was engineered for sporty drivability with refined emissions control. Emissions compliance was achieved through precise combustion tuning and exhaust aftertreatment, meeting Euro 5 standards across all production years.
One documented concern is high-pressure fuel pump (HPFP) failure due to inadequate lubrication from low-sulfur fuels, highlighted in Ford Service Bulletin TSB 14‑08‑11. This issue stems from premature wear of the pump’s internal cam follower. From late 2015, Ford updated the HPFP design and revised fuel rail pressure maps to improve durability.
All production years (2012–2018) meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/7890).
The Ford YUDA is a 1,596 cc inline‑four turbocharged petrol engine engineered for hot hatches and performance sedans (2012–2018). It combines DOHC architecture with direct fuel injection and a low-inertia turbocharger to deliver responsive power and strong torque from low revs. Designed to meet Euro 5 emissions standards, it balances sporty character with regulatory compliance.

The YUDA delivers sporty performance ideal for spirited driving but requires strict adherence to 15,000 km or 12-month oil change intervals using Ford WSS-M2C937-A (5W-30) oil to protect turbo bearings and high-pressure fuel pump internals. Early engines (pre-10/2015) are susceptible to HPFP failure due to cam follower wear—symptoms include hard starts and P0087 codes. Use only EN 228-compliant unleaded petrol with max 5% ethanol to ensure proper lubricity. Post-2015 units benefit from revised HPFP components and updated ECU calibration per TSB 14‑08‑11.
Oil Specs: Requires Ford WSS-M2C937-A (5W-30) specification (Ford TSB 14‑08‑11). Equivalent to ACEA A5/B5.
Emissions: Euro 5 certification applies to all YUDA models (2012–2018) under VCA Type Approval #VCA/EMS/7890.
Power Ratings: Measured under ISO 1585 standards. Output verified on Ford Focus ST 1.6 EcoBoost (2013) chassis dyno logs (Ford TIS YUDA-DYN-01).

ISO 1585: Road vehicles — Engine test code
The Ford YUDA was used across Ford's C1 and CD4 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Focus ST and revised cooling circuits in the Mondeo—and from late 2015 the Focus ST facelift adopted an updated high-pressure fuel pump and ECU strategy, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block near the exhaust manifold (Ford TIS YUDA-ID-01). The 7th VIN digit for YUDA-equipped vehicles is typically 'U'. All units feature a black cam cover with “1.6 ECOBOOST” embossed. Critical differentiation from naturally aspirated Sigma engines: YUDA uses direct injection, a turbocharger, and a 160-bar fuel rail. Do not interchange high-pressure fuel pumps between pre- and post-10/2015 engines—updated units use revised cam follower geometry (Ford TSB 14‑08‑11).
The YUDA's primary reliability risk is high-pressure fuel pump (HPFP) failure in early production units, with elevated incidence in high-mileage or infrequently serviced vehicles. Ford internal data from 2015 indicated up to 7% of pre-October 2015 engines required HPFP replacement before 100,000 km, while UK DVSA MOT records show fuel system-related warnings as a recurring advisory note. Extended oil intervals and use of non-spec fuel accelerate wear, making correct lubrication and fuel quality critical.
