Diesel Transit maintenance (TDCi, EcoBlue, Duratorq)
Most Transit engines in this family are diesel, including TDCi EcoBlue and Duratorq variants, so routine oil and filter servicing is the foundation of the maintenance plan. Many diesel Transits also use emissions control hardware (such as EGR and a DPF), so the schedule matters not just for durability but also for keeping fault lights and drivability issues at bay. Timing belt replacement is a critical scheduled item on belt-driven engines, and the exact interval can be fixed by time and/or distance depending on the engine. When you select your Transit and engine, double-check the specified oil grade and the filter part type, as these can change between EcoBlue and earlier Duratorq units.
