All my regens to this point have been 24 hours. Never had one start in between. Just got back from a 2.500 mile camping trip, pulling our 8,000 lb. TT. At the apogee of the trip visiting relatives in northern Colorado, the following happened. The truck was at 14 hours and my iDash “DPF RG%” was showing around 70%. The normal behavior is that it bounces around a bit when under 50, but once it reaches 50, it switches to tracking time and climbs steadily to 100 when it does a regen. These regens are silent, no EVIC notices unless on the DPF screen, no warnings or chimes. You would never know unless you were on the DPF EVIC screen or had something like the iDash. They vary a bit but generally take about 10 to 15 miles of driving and 15 minutes or so to complete.
This time the regen started at that 14 hour point and with the iDash at about 70%. This has never happened before. I had just filled up with fuel a bit earlier. This was at a time in the trip when I was at the relatives and not towing the TT. I had probably driven 10 or 15 miles from idle to 50 mph since the new fuel. Suddenly I got dings from the EVIC and a warning over the main gauge screen to keep driving. I was not on the DPR screen, this warning was overriding any screen I displayed on the EVIC. This has never happened before with either the warning message or the chiming. I would clear it, and it would come back 30 seconds to a minute later. I did continue driving for about 30 minutes, but the regen did not complete. I dropped off my wife and went out on a rural highway where I could cruise uninterrupted at 70 mph. After about 25 minutes of that, the regen completed. However, after completion, the iDash did not show some low % like it usually does, it immediately started at 48%. For the next 50 miles or so, most of it towing again, it bounced up and down between 46 and 54%. It did not just start counting up evenly after 50% like it normally does.
As we continued to drive, the iDash started quickly climbing towards 100%, sometimes going up a percent or two in just 30 seconds. When it got to around 85%, it slowed but still climbed on track to do another regen probably in what was actually going to be about 4 or 5 hours. I then needed fuel, having used up about 80% of that last tank of diesel, so stopped and put another 40+ gallons or so in the Titan tank. Got back on the road and about 5 minutes later looked at the iDash and the DPF% was back down to 40%. Drove the rest of the day with the iDash DPF% climbing and acting normally and then filled the tank again. The next morning the DPF% was down to 23%. Never had it go down like that before. Then the rest of the trip home it acted normal, climbing slowly to 50%, then evenly to where it is now at 99%, about to do another regen at what will be exactly the 24-hour point. This was over I think three new tanks of fuel, so back to normal for now.
All I can think is that the diesel I put in when in Colorado must have been bad somehow. Once that had been diluted and burned up, the DPF was happy again. Does this make sense? Anyone seen this themselves?
