What the warning tells you
The vehicle has detected a condition relating to its particulate filter system. Short journeys, an underlying engine issue or a sensor fault can affect how the system operates. Follow the owner’s manual for the wording and model.
What the technician may check
Available data can include differential pressure, temperature or the recorded history of regeneration. The readings make most sense alongside related codes and other checks. The correct next step depends on the cause and filter condition.
