Particulate Filter
I have a f350 SD diesel. My stupid particulate filter has regened about 14 times a day for the last 3-5 days. What the hell is the problem here. The dealership already replaced the filter once back in march. HELP

If you are shutting the truck down before the regen has finished, it will begin again shortly after the next startup. My understanding is that a lot of short trips will also result in more frequent regens. One or two per tankfull is about average.

Get it out on the hwy find a good hill, have something to tow and put it to the floor. Make it regen and let it finish, then monitor from there. If you are still having excessive regens it is probably a sensor as suggested above.

It can take a while for a complete regen cycle. Not saying you are, but if you actually ARE killing the truck before a complete regen, then it will lead to issues. If you keep doing so, you will eventually be on the side of the road as the truck will shut itself off until the dealership services it and resets the computer. Also frequent regens can be caused by a few known issues. Could have a faulty sensor as said before, dealer would have to check that out for you really. Also injector issues can cause more frequent regens. Check your oil level and make sure it is not overful. Check the inside of your tailpipe tips and see if they have soot build up on them. There should be almost ZERO soot on the inside of the tips; if there is soot this is an indication of a faulty DPF filter.
