First, disconnect the temperature and pressure sensors. Warm up the engine, turn off the vehicle, and wait until the filter cools down to a temperature of 40 degrees Celsius. Using a spray gun and a wand, inject 1 quart of cleaning liquid through the pressure sensor entrance. Leave the product in place for 15 minutes.

1. Drive at a steady speed. Cleaning your DPF while driving is most effective when you drive at a steady speed. This allows the filter to be cleaned evenly and prevents the build-up of new particulates. 2. Avoid stop-and-go traffic. Stop-and-go traffic is one of the worst things for a DPF.

Also, the flanged DPF the IH uses places the filter element about 12 or more inches from the heating element, and the small hole in the flange may reduce air flow reducing effectiveness. I could see IH requiring special techniques on this style down the road. No 2011 vehicle should need cleaning yet.

Regularly drive your vehicle at higher speeds on a motorway for at least 20 minutes. This allows the engine to reach the temperature required for DPF regeneration. 2. Service your vehicle regularly, following the manufacturer’s guidelines for oil and filter changes. 3. Never ignore the DPF light. Take immediate action to prevent long-term damage.

You'll know when the DPF has had it, the DPF, CEL, and GP light will all be on. If you have never had a light or lights come one, then you don't have an issue. The ECU uses two ways to estimate the soot levels, and pays attention to the highest one. It is possible to reset values, but to do so you should at least make sure one of the methods
