I have a 2014 Ram 1500 Eco Diesel with about 12,000 km on it. I am new to the forum and have a couple questions. I only travel 4 kms back and forth to work every day. I live in a small city and bought. the truck to hall the camper. I only go on the highway maybe once per month and find that I am must regen with every tank of fuel. Is anybody else having this problem? Does Chrysler follow this forum or is there a place where I can post my concerns and questions? I really like the truck but am getting very frustrated having to regen every tank full. Every time it says to regen I have to take it down the highway 50 km so it doesn't go into limp mode. I have already had to take it to the dealership once already.

Chrysler as far as I know does not follow the forum. If you search the forum there are a few others that have had this issue. I do not think it is normal however as I have never had a regen at 17,000 miles but I do tow about 1/2 the time. In the winter though I went through a few tanks of diesel without towing and still did not have to regen. Every time I run the truck I make sure I let it heat up all the way even on short drives and I will lock the truck with it running to let it do this if needed. Hope this helps

Are you guys talking an evic announced regen or unannounced regen? I've never had an evic announced regen since I bought the truck new 8400 miles ago. Now I have regens every couple hundred miles but the only reason I know that us because of my ultragauge.

I am talking evic announced since those force you to drive to clear them (my understanding of it at least). I assume if they are happening in the background and I am driving the truck as normal with no check engine lights or limp modes I am fine.

My understanding of the regeneration process is that its frequency is dependent on the amount of build-up in the particulate filter. Factors contributing to greater particulate build-up include low-speed driving, short distance driving, low engine temperature driving, and driving under load (towing, lot of mountain passes, etc.). Driving at highway speeds for extended periods of time both reduces particulate generation and--importantly--allows the exhaust system to run hot enough to burn off particulates as they accumulate.

Again, this is my understanding as to why and how the regeneration process works. Supporting this understanding, I have 22,500 miles on my 2014 Laramie 4x4 (delivered on 6/30/14). I am not aware of my truck ever undergoing a regeneration thus far (perhaps I just don't know that it is happening?). Many of my driving miles are at highway speeds of 55-65 mph for durations of ~45 minutes and several times a month at speeds from 55-80 mph for up to two hours. I tow only infrequently here in the mountain west and when I do so it is for distances of anywhere from 300-1200 miles each way at speeds anywhere from 30-45 on the winding mountain passes up to 75 mph on the interstate highways.

In summary, I'm not sure frequent regenerations indicate a problem (doesn't mean they don't, however). Instead, I believe regeneration frequency is a function of the factors noted in the first paragraph.
