Below are some of the issues that can trigger the P2002 code: DPF failure/damage; Exhaust leak; Excessive slow-speed or stop-and-go operation of the vehicle; Defective exhaust back pressure sensor; Constant short-distance trips and stop-and-go traffic limit the speed and temperature at which the DPF can regenerate.

If you do a lot of short-distance driving, try to combine trips so that you can reduce the amount of time your engine is idling. Idling produces a lot of soot and can cause your truck to regenerate more often. Another way to reduce regeneration is to make sure you’re driving mostly on the highway. The long distances and higher speeds will
An illuminated DPF light will cause an MOT failure. Since part of an MOT test is to check that vehicles comply to environmental standards, a faulty or missing DPF will cause an immediate failure. What to do if the DPF light comes on. If your DPF light turns on, the first thing you should do is attempt to initiate a DPF regeneration cycle.
How do you trigger a DPF regeneration? When the DPF warning light lights on the dash WITHOUT the EML / Check engine light, the DPF regeneration / cleaning button should be used. This warning light indicates that the DPF has reached its defined particulate matter limit and requires care, or, to put it another way, it is blocked.
Tuner/monitor options for manual regen. I have a 2015 F250 with a 6.7, I need to perform a manual regen on the DPF, and would like feedback on my options. It has about 70000 miles and is regen'ing every 250-300 miles, is loud with injector cackle, and bad fuel mileage. From what I understand the engine/injector noise is the computer trying to
One one occasion I had the DPF taken off and hydro-cleaned, and red stuff came out (probably oxidation from old cleaner residue). I also had a camera inserted into the DPF and no issues were found, it was not condemned. In the computer menu, the DPF service counter should count down to indicate when the DPF should be replaced.
