Check Engine Light/ Wrench and Drive to Clean Filter

well today after i filled my truck up with fuel upon starting it up the check engine light came on...i took it to advance and read the codes throws 2 codes. a P246C- AUX Emission Control
and a P2453- particulate matter trap diff.press.sensor circuit.
it keeps saying drive to clean filter and i have ran half a tank of fuel out of it and it keeps coming back on, it has even went to reduced engine power.
the check engine light is on and the little wrench is on the display.
im going to take it to a dealer in the morning and see what the heck it could be im assuming one of the half a dozen sensors in the exhaust. this is the first ive had trouble with the truck and it has 18,000 miles on it. im hoping my dpf back exhaust wont hurt me on this but i dont feel like putting stock back on after fighting with the thing all day.

went and spent all day at the dealership today, flash updated the computer, no help but i can make it regen on its own now thanks to the new update. it now shows the % full of the filter and upon leaving dealer it went to 100% in less than 3 miles. i got to top of mountain on way home and it was down to as low as 30% but by the time i got off the mountain it was 100% again. called dealer back and he called tech hotline and said to get it back in to check the sensors and some other crap but said it sounded like the dpf was too far gone and was going to need replaced. i have around $100 bucks in diesel wasted trying to clean the filter and the drive to dealer. diesel mechanic is going on vacation tomorrow thru friday so it will be monday before he can check it out and then god knows how long to get the new dpf in.

So you can go to a setting now and see how clog the filter is? Does the regen light stay on or does it still come on and gone in 5 seconds. Kind of sounds as if you may have some bad fuel. But I hope you get fixed up soon I hate having to go to the dealer.
