rolling REGEN question

Short answer is yes but alot of things need to happen to cause this. There is 4 stages.

Stage 1. Passive regen. Happens why driving at highway speeds you wont see a light come on but you may smell it, may also see the DPF TEMP light come on when you come to a stop. (Happens when the DPF Temp is over 800 Degrees)

Stage 2. Regen required. DPF light comes on. You can do a parked regen at this point or keep driving at highway speeds and it will do a passive, this happens when the passive regen has not been able to finish or been idling for extended amount of time.

Stage 3. Blinking DPF light. This is pretty much pull the heck over and do a parked regen. It might be able to do a passive but at this point your better off stopping.

Stage 4. Blinking DPF light and now a Blinking check engine light. This is the omfg I'm boned stage, depending on the truck it will now derate it self and shut down if unable to do a parked regen. (Passive regen no longer a option) May require a international tech to come out and force a regen.

The maxfarce has a very complicated pos egr system which tends to plug DPF filters quick. Also if you idled the truck, you may see lots of blue smoke as the regen system kicks in and the system burns off unburned fuel from the engine. These motors are terrible when it comes to plugging up, as long as your not seeing a DPF light come on the truck is doing passive regen's correctly.

Hope this helps some, the maxfarce is a horrible horrible engine.

Edit.
Btw, Whoever told you that you needed 35k in the box to do a rolling regen is a idiot. The regen system has nothing to do with weight, It can and will do a regen why bobtail as long as your holding highway speeds long enough. (35-50 miles depending on the regen and speed)

 

not driving a international. but all the trucks could have a variety of problems that could cause loss of power.

it's possible that the light may malfunction, i suppose. but anything that goes out, would cause the same sluggish symptons.

 

How many miles on the truck ? When was the DPF Filter last Baked ? Sounds like its near the clogging point in gen and needs to be baked. Its supposed to be done every 250k.

 

I would, if its skipping stages or if the fuel milage is going to crap could be a sign of a over due baking. The maxfarce wont throw a code until the thing is sooo plugged the engine cant run. They also tend to clog alot easier then Cummins, Detriot, Pac due to the over complicated egr. Another thing that can happen is the EGR cooler can go on those causing you to throw decent amounts of coolent in the DPF causeing to to Clog, Crack or stop regening all together.


If you are using coolent this is also something to look at.

 

my 2013 was going to crap with the regens every couple hrs wanted me to do a parked regen. Put it in the shop and turns out it was showing 100% soot and 0% ash.they told me it was the injectors over fueling (mpg was crap also) they put 6 new injectors in it and baked the filter. Less than a month later the MIL light comes on, pull it into a different shop and they diag it as the low flo side of the egr crapped out and that i prolly didnt really need injectors that is was this causing the over fueling problem. Didnt bother me really since it was all warrenty work. So i would get them to go over the egr if your having regen issues

 

If you just had your EGR cooler replaced then you most likely had coolant get into your DPF when the EGR cooler failed which will cause the soot to stick and plug up the DPF to the point is will need an off the truck cleaning or maybe even a replacement. While they are servicing the DPF have them double check the EGR cooler, Maxxforce motors are known to go thru EGR coolers. Also, have them clean or replace the upstream and downstream exhaust sensors as they will also have been coated in coolant when the EGR cooler failed causing soot in the exhaust stream to stick to them making them give false readings to the ECM. This could be why your motor will not throw codes in the correct order or do a complete regen when it should.
