I bought a 2019 3500 with a 6.7 HO. I bought it to tow our 38" fifth wheel RV once it comes in. 15500 GVWR. I don't have a ****** yet and this is my main mode of transportation right now. I noticed it may have had a tune in it because the exhaust brake does not shut off with the truck and the DEF gauge has read 100% since I bought it almost two months ago. There are no deletes that I can tell.
Since buying the truck I learned some things I was doing wrong. I warm the truck up every morning before driving to work (about 10 minutes idle time). I did this year round with my gas vehicles as to bring everything up to temp so condensation doesn't kill the exhaust system. I only have about 3-4 miles to drive to catch my rideshare. I drive home cold form the lot where they drop me off. Other than that its mostly around town driving with only occasional highway.
Last Friday I got the "Exhaust filter almost full drive at a consistent speed" warning. I came to this forum and learned what that was and, on Sunday morning, I took to the interstate. After a steady 70 MPH (about 2100 RPM) it took 26 miles then the message disappeared and my information center returned. I figured the regen was complete (I cannot find any gauge for this), and I reversed direction on the interstate and drove home.
Monday everything seemed normal. Tuesday evening, while driving home, the warning message was back. I didn't use the truck today and decided I will skip the rideshare tomorrow and drive the truck to work (44 miles of interstate each way) to clean the DPF again. Maybe even use tow/haul and keep it out of OD.
I took the truck out to fuel it up for tomorrow and, on the way back from the gas station, I got the "Exhaust filter full, reduced power, see dealer" message. I don't see any manual regen button or software option in the info center.
My questions now are; can I force a regen, either manually or by driving...or is this "see dealer" message the kiss of death leaving me no option but going to the dealer? Can I buy a scanner/device to allow me to do this myself? I am familiar with using tuners from when I had my 2010 Camaro SS.
I am afraid the dealer will want to charge me $3K to replace the filter and then rag on me for the ECU tune and charge me to put it back to stock. The truck has 119K miles so all warranties are gone.
Sorry this was so long but I wanted to give you as much info that may be pertinent. I will hold off for a couple days before taking it to the dealer in the hopes you guys and gals can help me out. Thanks in advance for any assistance.
