Try to keep the car happy and the emissions system in a happy passive state, in this state fuel economy is best, and less fuel is needed to dose the dpf. keeps the soot levels low. (best) Active: when the car is doing a lot of city driving and has not had the opportunity to do a regen naturally. It will dump excess fuel to dose the dpf.
Regeneration in the "new and improved" trucks can take from 25 minutes to 50 minutes, so plan accordingly. All that extreme heat from the burn-outs tore a hole in my exhaust pipe not to mention extra heat causing damage to engine components like starters, turbos, wiring to the computers which can totally mess up your day if you have more than 7
Regeneration, or regen, of the DPF filter is the process that burns the soot accumulation that is inside the DPF filter. Educating yourself on what a forced regeneration is and how it works will help you understand your aftertreatment system better. Forced regeneration is performed when a diagnostic scan tool starts the regeneration process.
Some garages can do a forced regeneration. This process should cost around £100, but it usually clears the DPF of soot, letting it do its job properly. Most DPF issues are caused by incomplete regeneration and if left, these issues could increase your exhaust emissions and put your car into a speed-limited limp mode.
The GPF is a particularly ingenious device for improving the carbon footprint of vehicles. Largely inspired by the particulate filter in diesel cars, it takes the recipe from it and adapts it to petrol cars. The device works beautifully and is reliable, durable and efficient. Its extended life makes it a particularly well thought-out and
Because the DPF is under the car, not 'close coupled' in the exhaust manifold, the car needs to be driven quite a long way (50 miles) at 2000 - 2500 rpm to get the DPF hot enough to promote a passive regeneration. An active regeneration will happen automatically, but if the DPF is too stuffed up with soot for this to work, the post-injected
