This happens at approximately 30% of your total DPF soot rate. I originally thought that was the only way that I could clear that message when in fact that message will always display every time that your truck is going into regeneration. I immediately went back to my Chevys and fords and got on the freeway.
I recall the first time that I saw the notification regeneration in progress. I have seen that regardless of freeway driving or stop and go traffic I am seeing the regeneration process take place. The gauge in the dash is a good addition but isn’t 100% accurate.Īfter 2800 miles of 90% city driving here is what I have noticed.įirst no matter where you’re at your truck will go through a regeneration process. My Chevys gave me serious headaches and the emissions fell off My fords gave me few issues on the DEF and DPF regen process I have had a number of trucks with emissions and all of them acted differently in some way shape or form. I guess what I'm getting at, is, that it would seem these trucks can regen the exhaust system at low speeds around town, contrary to what I believed was the case. So for this cycle I am going to stay under 50 until it finishes just to see what it does. The filter gauge is coming up when i start it so I can see I'm under 1/4, so it is actually burning out some soot, just slowly. I have been in stop and go all afternoon yesterday, and then this morning and its still going to regen as soon as I back out of the driveway. I was driving yesterday and while stopped at a light, the message came up saying regen in process. Now, the most recent cycle, I havent been over 40 mph in the past 2 days. So that cycle was not what I was expecting, but I thought at least I must have gotten up to speed enough for the truck to think it was good to do it and then just committed to it once it started.
it took no time at all to finish when at highway speeds. I was thinking that it wouldn't be able to do any regeneration while in stop and go traffic, at idle essentially. Once I make it to the freeway, I'm at highway speeds for 3-4 minutes and the regen message goes away and Im showing an empty filter again. Its still up so I figure on my way home I will swing out to the freeway and make a little 20 minute loop to let it do its thing. its not critical at this point, right? Well the message stays on the dash through about 30-40 more minutes of stop and go. I expected the regen to cancel, after all the filter was less than half full. I made a few stops and stopped and started the engine in the process. hmm, well I did get up to 50 back there a minute ago, maybe that initiated it and now it has to finish, even though I'm in stop and go traffic. Then on the 3rd or 4th cycle, I was driving down the road and it said it was in regen mode. 20 or so minutes go by, and the gauge pops back up showing an empty filter. I watched the first couple regen cycles and it happened to kick off when I expected, the filter was about half capacity, and I had hit the highway and held speed for about 15 minutes when it started regen. I love having the gauge in the instrument cluster that show the level of the DPF, as well as when it is actively in regen mode. I was under the impression that the trucks had to maintain at least 50 mph during the regen process to be functional. So all I know about the regen process, I have heard from friends or read online. So my new RAM 3500 is my first ever diesel truck.
