0242f-Diesel particulate filter restriction-Ash accumulation

--------------------------------------------------------------------------------

Hello to forum, I recently bought an 08' 3500 megacab 6.7L 4x4, Brand shiny new to the diesel and dodge vehicle world. It has been running great but the check engine light came on 800 miles from home, returning to Texas, I got the message, service required see dealer. Also had loss of power down to 50 MPH, max speed w/i a mile from the house. I parked the truck, read the manual, replaced the CCV filter, cleaned the EGR valve and EGR cooler, and cleared the message on the overhead. Couldn't have done it without yall's help. Made a couple of miles to test. The power appears to have increased back to typical, but the service required, see dealer returned. Im getting the following on the OBDII: 0242f, 0242f-PD, Monitrs-3 INC-catalyst, 02 snsr, EGR... 4 ready-Misfire, Fuel, Comp, 02 HTR. I drained the fuel filter as well. I now am attempting to find the source of the 02 sns problem using an earlier thread posted, but have no knowledge of the 0242f- Im assuming that is an additional filter I have not yet found. I also am wondering if there is additional maintenance of the catalytic converter to be done? it concerns me about the EGR, did I possibly not clean the EGR Cooler as well as needed(was a pain to take off)?... and as for as the rest of the codes: Misfire, fuel, comp & 02 HTR, Im still researching. Any advice? Ignorance is bliss, until it bites you in the back side.
