I just got this 2011 Ram 2500 and haven't noticed a regen cycle within the 250 miles I have driven it. What is a typical cycle (miles) that these trucks regen? Is there a dash light to let you know while it is in process?I do short trips mainly 15-20 miles one way.

No light when regen. Only way I know mine is doing it there is a smell of (rich running) diesel at red lights. Nothing really noticeable.

Twenty miles is too short to complete a regen, and there's no light. I could tell by the smell, and you'll see fuel mpg drop way off when it happens.If you go too long, you'll get a message about reducing performance, and it can do a regeneration parked in that situation.YMMV if they have changed the software since new, I traded mine in some time ago.

About twice a month you need to get it on the highway and run it HARD for about an hour. Short trips will soot up the DPF really fast. Once its sooted its near impossivle to clean it out. The best thing is drive it hard and keep the revs up. Also running with the EB on all the time helps.

Ok thanks I will keep a more watchful eye on the milage. Lately been monitoring the coolant temp since its cold out here (-3F).I see on some semi trucks the drivers have some control on the regen cycles. I wonder if that will ever filter down?

The DPF regen off switch is only intended for use when you are on a yard that requires you not regen such as oil refineries. Although it does tend to get drivers in trouble since you can only turn off a regen a certain amount of times. If you go past that limit then your truck will go into limp mode and requires a forced regen by a technician with Cummins software.I highly recommend you get a Edge Insight CTS2 or something similar if you are wanting monitor egens. Not only will it tell you when you are regen, but it will also tell you EGT flow, DPF back pressure, and a whole host of useful info in real time.

YMMV if they have changed the software since new, I traded mine in some time ago.
