Character
1.8 TDDi / DI (Endura-DI)
"Pre-common-rail Ford 1.8 diesel (Focus Mk1 TDDi 75/90 hp, Fiesta Mk4 1.8 DI). Direct injection with an electronically controlled rotary pump. Owners rate it far better than the later 1.8 TDCi; the injection pump and its control unit are the one known weak point, typically after 120,000 km."
EcoBoost 1.0 (post-2018)
"The revised 1.0 three-cylinder in the Fiesta Mk8, Focus Mk4 and Puma (cylinder deactivation, mild hybrid from 2020). Most got a timing chain between 2018 and 2020, but some engine codes kept the wet timing belt and every version still drives the oil pump with a belt running in oil. Use only the Ford-approved oil and keep the change interval; check the engine code before buying."
