    We just got this 2015 Cascadia & its my first experience really with regen. I got up this morning & the regen light is on... not flashing, just on. So, I got the manual out & it said to get exhaust temp up by driving. Well, I cant drive cause I am getting loaded. Can I just idle up? Can I just use the cruise & idle up? The cruise will only allow me to idle up at about 900 RPM's is that enough?

    Just because the light is on does not mean you have to do it right now. But when the light starts flashing is when time get critical. You can do a parked regen and even though your cruise will only allow you to idle at 900 rpm, when you press the regen switch it will idle at a higher rpm and you dont need to mess with the cruise. If you are getting loaded and you think it will take a bit, 40 min to an hour, I would just regen it there.

    OK thanks. Actually, after I posted, the light started blinking & I had to regen anyway. It only took about 10 or 15 minutes to regen this time. Maybe because I had idled up before the light started blinking? Anyway, The idle dropped & I guess I am good to go.

    Also make sure your engine fan and a/c is off. That allows the temps to go higher. Most trucks will regen on the fly, just don't hit the clutch or brakes.

    That brand new truck should not be needing a manual regen already. It takes DEF right? That is the primary way it gets rid of soot. If it is needing regens already you might be looking at a head ache truck. I've got a 2013 max force with the re engineered regen system prior to them going to DEF. It has gone 140,000 miles with no regen lights no triangle. Truck uses no oil. Only issue so far is it needed a regen cooler part. Forgot the name of the part. Coolant was vanishing with no hint where it was going.

    A regen should take almost an hour. You may have a faulty pressure differential sensor. When they fail it can cause the system to think it needs a parked regen when it really doesn't.

    My Volvo had the same problem. Constantly asking for parked regenerations every 300 miles and then lasting less than half an hour. It was that sensor.

    I was thinking the same. Why would a new truck be needing an active regen let alone a parked regen? Only conditions I can think of is mostly off road or low speed city driving when passive regens get continually interrupted.

    Keep in mind a couple of things about my specific situation. I work for a small plastics recycle company, I am the only driver & this is the only truck that is a Ryder Lease truck. I am hired to run mostly local & short runs. Otherwise, we ship our material by other trucking companies all over the US.
    I run usually within 100 - 150 miles. I do have a couple of runs that are 300 miles or so one way. All of my runs are in Louisiana, Texas, Mississippi & Arkansas. Last night I was in Austin, TX. Since I am only out over night once or twice a week (otherwise I am home every night), we do not have Gen Pac's etc. The one or two nights I am out, I just idle to run the air conditioning. My stuff being mostly in Louisiana & Texas, specifically Austin last night, I idled. I suspect, that was why I needed a regen this morning. It idled all night & wasnt able to burn all the soot out of the system.

    I have had the truck since last Monday (6/9/14) & have idled all night 3 times now. Twice with no problems & once I needed a regen.

    I do not know if this is the cause or if it just happened this way.

    I am interested to know if you guys think this was the problem.... & if it will continue to be a problem. Is this something I should expect regularly..?? What can I do to prevent this (regen) if I am going to idle a night or two a week. Will idling the truck up a bit help? I think its idling at about 600 RM's... I can idle it up to 900 RPM's.

    I'd guess you're correct, the extended idling and short runs are combining to cause your issue. The motor will create less soot at 900 rpm but not completely eliminate the issue, just increase the time between regens.
