Diesel Transit Custom (EcoBlue/TDCi and Duratorq)
Most Transit Custom engines in this family are diesel, including 2.0 EcoBlue / 2.0 TDCi (EcoBlue) and earlier 2.2 TDCi (Duratorq) variants, so keeping on top of oil-and-filter servicing is key for turbo and EGR longevity. Diesel models may also have DPF-related service considerations, especially if the van does lots of short runs, so it is worth sticking closely to the specified engine oil grade and service timing. Where a timing belt is fitted, belt replacement is a major scheduled job and the correct interval depends on the exact engine. Cooling system condition and air filtration also matter on working vehicles, so check the schedule for items that may be time-based as well as distance-based.
