If your car has an automatic transmission, shift your gears in a manual mode by moving the gear shift gently. No need to use the speed limiter, it is with no seeming value added. Ride like this for a minimum of 30 minutes. This will initiate a regeneration cycle, and your DPF will be cleaned.
What happens when DPF is blocked?
The DPF filter is designed to conduct exhaust fumes out of the car’s engine, so when it is blocked, these fumes cannot leave the engine as quickly. This stops the engine from working to its full capacity and will invariably reduce your fuel efficiency.

How often should DPF be cleaned?
Generally, it’s recommended that a DPF be cleaned roughly every 150,000-200,000 miles. At this point, ash in the filter cells begins to harden. This hardening can cause the filter to crack, resulting in permanent damage.

Whether you have a light, medium or heavy-duty diesel vehicle, professional cleaning of DPFs is the only long term solution for DPF problems other than an expensive replacement.
What happens if you don’t clean DPF filter?

Do short trips hurt diesel engines?
Short trips do not let the diesel engine get warmed up well enough to remove deposits and keep carbon from accumulating and being burnt off. That’s all really. You need at least 15-20 minutes of loaded running to get it to temp and say about 1 hour straight a month of highway driving minimum to keep it all happy.
Why do diesels last longer?
Diesel fuel is a type of distillate fuel that is essentially produced from crude oil, which gives diesel engines slower cylinder wear than gasoline engines. This gives diesel fuel lubrication properties that extend the overall lifespan of the engine.
