Here is a short list of issues that most people complain about with a clogged DPF
Fault Codes / Limp Home Modes Triggered
Constant Regeneration processes
There are some other lesser known issues too like:
Increased Fuel Consumption
Decreased Turbo life due to back pressure build up.
Cleaning or Remanufacturing?
The industry has really gone to three levels of cleaning:
1. Pneumatic / ‘Blow’
2. Bake and Blow
It is obvious that the cleaner your filter is when going back on the vehicle means it will last longer in that particular service. And it’s not just the cost of the cleaning itself that needs to be considered. Also think about all of the on-costs. Labor to remove and refit, parts such as Gaskets and clamps. But that you also have added costs like increased fuel consumption etc.
