even though the label on my sun visor says i can do a re-gen while driving, it does not happen. i have to do it while parked.
to me, why affix such a label telling us this can be done (while driving) when it cannot..???

So, no, you can't do anything to activate a regen when you are driving. It's automatic.
The problem with governed trucks is the RPMs often don't get high enough to clean it out when you are doing top speed. I usually drop a gear and go at the upper RPM range and that clears it out pretty quick. -
The trucks I drove without DEF would indicate a driving regen and a parked regen icon would come on if it was necessary, which was often.
I may not be right about your situation, but I wanted to share my experience. -
my idle times are "nill" as i only idle at high RPM's in the winter to warm it up, (about 30 minutes), then i shut it down. then re-start when i am ready to leave. at each stop i do, it get's shut down. and nearly all my drive time is at 65/70 MPH, except of course, when i get off the highways to make my stops. so very little low RPM/city driving.
i will try the one gear lower/increase the RPM's from time to time, thanks for the tip.
what pee'd me off was the fact that the sun visor label said I COULD do a regen at highway speeds. but the truck simply would not do it.
i can only hope that in short time, like BEFORE i retire (in 10 more years), they get this crap straightened out.
after i retire, i couldn't give a flip about trucking, let alone the emissions.G.Anthony Thanks this. -
If it's forcing you to do a parked and never idling there is probably a problem somewhere else. Like you said in another post though, they do clog up over time eventually. They do need to be manually cleaned. A Freightliner mechanic told me the carriers are wanting them to push it back further and further on the mileage to pull the filter and clean it.
Smaggs Thanks this. -
I, whole heartedly, agree with this. -
I was doing a parked regen a couple times a day there for a while. Finally the truck derated and had to go to the shop. 400,000 miles on the DPF, cleaned twice that I know of. They put a brand new one in, and and EGR cooler as well as a new 7th injector which was the main culprit it turns out, is the critical thing that needs to work properly to shoot the fuel in to burn at the high temps to cook out the soot.
So what I'm getting at is the truck needs to be plugged into the computer to find any fault codes to find out why it is requesting parked regen all the time and not getting satisfied. -

the shop mechanic told me it costs around $2,600 to do the cleaning. they have to send it out to a company that can do this.

we took the one off my truck to KW, they had it overnight to clean it and return it. IIRC, it was under $2,000 for the service, still didn't correct the problem, fuel pump and 7th injector had to be replaced as well
