Short journeys, soot and interrupted regeneration — plus the importance of proper diagnosis.
A DPF captures soot from diesel exhaust. Over time, the vehicle needs to regenerate the filter by burning off trapped soot under suitable operating conditions.
Repeated short journeys and certain fault conditions can prevent regeneration from completing. Warning lights or reduced power are reasons to seek diagnostic help rather than continuing to ignore the issue.
Engine management, sensors, injection issues and other faults can contribute to recurring DPF problems. An excessive ash load or damaged substrate may also prevent a filter from working correctly.
Have a qualified garage check the vehicle and determine whether regeneration, specialist off-vehicle cleaning or replacement is appropriate. Correcting the original issue is vital.
