Parts for your 2015 Ford Transit-Ignition coils

2015 Ford Transit ignition coils: used or not?

For Australian and New Zealand–delivered 2015 Ford Transit models (VO/VE), ignition coils are not relevant because these vans were factory-fitted with Duratorq TDCi diesel engines. Technical references that outline this include the Ford Workshop Manual for the 2015 Transit (diesel powertrain sections covering Duratorq TDCi), Ford’s ETIS/Microcat parts catalogues for the VO/VE Transit listing no ignition coil assemblies for diesel variants, and Autodata/AllData system descriptions that specify glow plug systems for these engines instead of spark ignition. By design, diesel engines don’t use spark plugs or coils.

Why no coils? Diesel engines operate on compression ignition. Air is compressed to very high pressure and temperature, then fuel is injected directly into the hot air, igniting without a spark. To aid cold starts, diesels use glow plugs and a glow plug control module, not ignition coils. The Ford 2.2L Duratorq TDCi (common in AU/NZ Transits) and the 3.2L Duratorq (where fitted) are classic examples covered by the Ford service information—both list high-pressure common-rail injection, glow plugs, and no spark or coil packs.

• 2.2L Duratorq TDCi (AU/NZ): No ignition coils, uses glow plugs and common-rail injection.
• 3.2L Duratorq TDCi (selected markets): No ignition coils, uses glow plugs and common-rail injection.
• 3.7L Ti‑VCT V6 petrol and 3.5L EcoBoost V6 (mainly North America): Coil‑on‑plug ignition coils are fitted.

So, for local AU/NZ 2015 Transits, talking about “ignition-coil replacement” doesn’t apply. Owners concerned about starting performance or rough running should look instead at diesel-specific maintenance: glow plug health, fuel filter condition, injector performance, battery voltage, and ensuring the correct low-ash oil and quality diesel are used. If a Transit is an imported petrol model, it will have coil-on-plug units on each cylinder, confirming via VIN/engine code or checking under the bonnet for spark plugs is the quick way to tell.

Popular questions

Does a 2015 Ford Transit have ignition coils?
Most Australian and New Zealand 2015 Ford Transits don’t have ignition coils because they run Duratorq TDCi diesel engines. Diesels use compression ignition with glow plugs rather than a spark system.

Petrol Transits (more common in North America) do have coil‑on‑plug ignition coils—one per cylinder.

How can someone tell if their 2015 Transit uses coils?
Check the engine type. If it’s a 2.2L or 3.2L Duratorq TDCi, there’ll be no spark plugs or coil packs—just glow plugs and a high-pressure fuel system. The build plate/VIN data will also list the engine code confirming diesel.

If it’s a 3.7L Ti‑VCT or 3.5L EcoBoost petrol, there will be individual coils mounted over each spark plug under the coil covers.

What should be serviced on a diesel Transit instead of coils?
Focus on glow plugs and the glow plug control module, the fuel filter (change at the recommended interval), battery and charging health, and proper diesel quality. These have a bigger impact on starting, smooth running, and emissions on a diesel than any spark system would.
