exhaust regeneration

I just bought the truck lastnight and today it says it needs to be preformed. I looked in the owners manual and it says run at highway speeds for 45 minutes should take care of it. Could someone explain exactly what this means. Or any tricks to get this done. This is my first diesel pickup and first dodge truck.

A gentle suggestion . . . do a search and/or actually read your owners manual . . .

This topic is beat to death on a regular basis . . .

The idea is to get the truck hot to help with the regeneration process in the DPF. The best way to do this is run at highway speeds, if you can tow something that will reduce the time needed since the truck runs hotter when towing. Try not to idle more than a few minutes unless necessary and it should reduce the frequency of seeing this message.

Welcome to the forum and welcome to the amazing world of RAM.

An overly zealous EPA has required that the manufacturers place unnecessary and restrictive emissions devices on our newer trucks. a filter placed on your truck needs to be cleaned, a process that involves you getting your truck nice and hot for a while. I have not heard of this needing to be done so early. How many miles are on your truck? If you have virtually no miles and did not sit and idle all day, I would take it back for a diagnosis. Some claim that a regen can be completed by idling for a couple of hours. I have no first hand experience with that as a way to accomplish this. I have a new 2012 and have not had a regen yet but then again, I tow heavy most of the time it is running.

Hope it all works out.

Mike

if you have over 200 miles on the engine, towing or not, the dpf has performed a regen. you may not realize it has done it, but it has. when towing and getting 8-10 mpg, it is very hard to tell when it regens. when not towing, its easy to tell just by looking at the "on the fly MPG". i have not gone over 200 miles without a regen EVER.

When you take it out on the hwy, run it in 5th gear at around 2500 rpm. This will force a regen and it will take much less time. ")

Probably from sitting on the lot being started and shut down who knows how many times. You said three hours on it and six miles, thats alot of idle time. Go for a nice drive in the new truck.

They say 45min at highway speeds but I've found it takes a lot less than that.

The one active regen I had to do was over in less than 10min, and I didn't even get to the highway! If you have a manual it helps to run it in a lower gear at higher RPM to get the exhaust nice and hot. Same goes for when you're out on the road trying to regen; its better to run a gear down at high RPM than it is to keep the RPM real low. It's not doing much good if you're turning 1200RPM at 55mph.

Also as a general tip, if you get a chance to take the long way home on the backroads now and then do it to help keep the DPF clean. Keep the RPMs high and romp on it a little and that'll work.
