Cleaning the DPF regularly can help ensure that your vehicle meets emission regulations, prolong the life of the engine, and maintain optimal fuel efficiency. While many car owners rely on professional mechanics to clean their DPF filter, it is possible to clean it yourself if you have the right tools and knowledge.
Don't. Cleaning the dpf is not necessary even at 100K miles. It's also not made to be removed very easilly. It's quite the task to get it out. It's certainly doable, but a truck stop is probably expecting the removal to take five minutes, not two hours. There's also the chance they will ruin something in the process.
