Looking for Advice on Code P2459 resolution. Dealer stated they had their Top Diesel Mechanic work on my 2021 Ram 3500 which popped the error code. Presumably, they ruled out Fuel System Failure, Base Engine Failure, Fuel System or Air Handling System Failure, and Faulty Diesel Particulate Filter. They stated that I had an Air Filter that used glue strips in its construction and that created the problem. I had recently put an OEM filter in. Then they added that the filter was clogged because I had not serviced it as required. I told them I would take care of the filter (as I had doubts on what they were saying). They charged me $1300 to flush the filter. When I picked my truck up they stated they went ahead and changed the air filter as a courtesy. So now I had no way to verify what they told me. I also researched the Particulate Filter Service they said I neglected to perform. This service is to be performed around 75,000 miles. NOTE I had just hit 40,000 miles.
The second short trip I took the filter gauge quickly ran over 30% and threw another P2459 code. Their service did not fix the problem and I know feel taken. I talked to the Assistant General Manager and expressed my dissatisfaction and requested they look at my vehicle again. He assured me his Service Department would now return my calls, which they had been ignoring, and contact me to schedule another appointment. Nothing but crickets so far.
Presuming they actually troubleshot the normal causes for this code, what else could be causing the problem. The majority of mile on my Ram are highway miles.
