Diesel (EcoBlue and Duratorq) service considerations
Most Ford Transit Custom variants in this family are diesel, commonly using 2.0 TDCi (EcoBlue) and earlier 2.2 TDCi (Duratorq) engines. Diesel servicing typically centres on correct engine-oil specification and timely oil and filter changes, as frequent short trips and heavy-load use can accelerate oil contamination. Many diesels also rely on emissions aftertreatment, so keeping the air intake and exhaust system in good order and addressing warning lights early helps avoid secondary issues. For belt-driven engines, confirm the correct belt replacement interval for your exact code, as schedules can vary between ranges and updates.
