If your diesel vehicle has displayed a DPF warning light, it is telling you that the diesel particulate filter needs attention.
A DPF, or diesel particulate filter, is part of the vehicle’s exhaust system. It captures soot from the exhaust and periodically needs to remove that accumulated soot through a process called regeneration.
The exact regeneration process varies between vehicles, so your owner’s manual should always be checked for the manufacturer’s instructions.
Why do DPF warning lights come on?
One common contributing factor is the way the vehicle is driven. Diesel vehicles that regularly do short trips, low-speed driving and frequent stop-start journeys may not always provide the conditions required for the DPF regeneration process to complete. Ford Australia, for example, notes that repeated short-distance driving can make it difficult for some vehicles to complete DPF regeneration. RACQ similarly explains that slow, stop-start driving can prevent regeneration from starting or completing on some DPF-equipped vehicles.
What should I do when the DPF light comes on?
Don’t automatically assume that simply driving the vehicle harder will fix the problem.
Different manufacturers use different warning systems and regeneration procedures. Some vehicles may require a particular driving cycle, while others may require diagnostic attention.
If the warning remains on, additional warning lights appear, the vehicle loses power or the vehicle enters a reduced-power mode, it’s a good idea to have the vehicle properly diagnosed.
Can short trips cause DPF problems?
They can contribute to DPF regeneration problems on vehicles that require particular exhaust temperatures and driving conditions for regeneration.
If your vehicle is mainly used for short trips around Thornton, Newcastle or nearby suburbs, tell your mechanic how the vehicle is normally driven. That information can be important when diagnosing a DPF issue.
