MAXUS DELIVER 9: Steady or flashing yellow DPF light indicates regeneration is required
Symptoms
- The yellow DPF light stays on or flashes, with a message requesting driving or stationary regeneration. [1]
Possible causes
- The manual associates particulate accumulation in the DPF with regeneration warnings; prolonged low-speed, low-load operation, repeated starting and stopping, and extended idling hinder normal regeneration. [1]
Checks
- Distinguish the steady level-one indication from the flashing level-two indication, and check instrument messages and engine/DPF-related faults; whether regeneration is possible must be determined using all conditions in the source manual. [1]
What to do
- Have a qualified technician follow the complete procedure for this model. Stationary regeneration requires an open, ventilated outdoor location without combustible materials, and the temperature, parking, gear selection and other conditions must be met; have a service provider inspect repeated failures. Do not equate a warning directly with a need to replace the DPF. [1]
