What should I do if the DPF warning light comes on?

If the DPF warning light illuminates, it suggests that the diesel particulate filter is full and needs to regenerate.

To effectively maintain and address this, take your vehicle on long, high-speed drives, preferably on motorways, as this facilitates the regeneration process where the filter burns off accumulated soot. Ideally, these drives should last between 30 to 50 minutes to ensure the exhaust reaches the required temperature for efficient soot removal.
