FILTER CLEANING
The Diesel Particulate Filter (DPF) on all 2007 and later engines must be cleaned at proper intervals of 250,000 miles (400,000 km or 6,000 hours) or less depending on duty cycle and manufacturers recommendations.
Many 2007 and later engines also have an Aftertreatment Fuel Injector (AFI), or doser, that is part of the exhaust system. Manufacturers recommend cleaning this component at approximately 100,000 miles (161,000 km or 3,000 hours) to prevent premature ash build-up in the DPF.
Left unchecked, soot and ash collected in a DPF can damage or destroy a filter resulting in a DPF replacement cost of $3,000 or more and unwanted, unscheduled downtime.
