Hopefully i can help..

If your refering to the diesel particulate filter - as you may of gathered these a generally are self cleaning only if the car is able too..that means anything from short journeys or the car seldom used on trips etc can reduce the life of the DPF itself..To extend the life of any DPF it requires the car to be able to self regenerate and this usually occurrs under high use/motorways journeys enable the dpf to reach it desired temperature to burn off the excess soot captured - normally these do require checks or possible replacement at the 100-150,000miles mark - but normally some filters can last way beyond that provided the filter itself is able to self-regenerate,the correct engine oil is used...I do hope this helps..if you need to ask anything else then please just continue before you rate
