DPF 100% Renen Occuring Daily - 2016 75,000 miles

[Mallardsx2]

So I'm back. The last time I posted here was with issues a year ago. Now I am having even more issues.

Yesterday I had the 100% full error come up and it started to regen on the highway. Driving at speeds up to 80 MPH. It Regen'd 3 times in an hour and then it threw the check engine light.

Then it went into 90% regen mode and 80% regen mode then said completed.

I took it to the dealer and they cleared the check engine code.

This morning it went into regen mode again and completed it.

WHAT IS GOING ON WITH MY TRUCK?

I'm really starting to freak out.

Dealer told me that none of this was covered under any warranty.

What is the cost of getting this DPF cleaned or replaced?

What are my options at this point?

It has been very cold here in GA the last could of mornings. Could this be causing the issue?

Your DEF isn't covered under the mandatory Federal emissions warranty? I'd question that.

My system was a problem right off the bat when I bought my 2017 CTD. No one could explain the problem, it kept coming back and the truck went into limp mode on me once 14 miles North of NoWhere...that was the last straw.

I know a lot of folks don't have problems with their systems. In your case it sounds as if you have a sensor issue. There are quite a few of them in that system.

Your options?

1. Call the dealer on their initial findings that it isn't covered under warranty.

2. Have it fixed.

3. Trade or sell the truck.

4. Remove the system if you plan on keeping it and enjoy a better driving, more fuel efficient truck with more power by having a full DPF, EGR & throttle valve delete done along with a programmer, tunes and aftermarket exhaust.

Good luck.

Programmer delete and then.... at least the engine problems get solved. I would have to agree with step 4 in the post above. Don't forget the CCV filter under the valve cover they can clog and the engine will die.

Just replaced that 10K miles ago. Took 5 minutes.

How cold is cold. I just had a machine keep doing regens and then locked me out after a failed forced regen. Turned out to be that it couldn't get the temp high enough to do it. Had to do a dealer reset and then cardboard on the rad and tarped over the engine bay to get the heat up. Then it did the regen successfully and has been good since.

That’s what I did when mine did that at 35,000, and the dealer said it was not covered to clean egr, etc, finally got them to cover it then again went into limp mode , 350 miles from anywhere with Rv ! Did the kit , trying to get best mileage and tunes figured out, but I like it

 

[MADDOG]

Great! What tuner did you go with?

 

[cnovel]

GDP , still trying to figure out the tunes , to get best mileage, it was from sinister , edge unlock , 4” exhaust , a lot more room under the hood , I have not driven it much to figure out tunes , any input is welcome
