For once, I'm slightly concerned (mostly curious) as this is the fastest I've seen these numbers increase.

98 miles and I've gone from 1.14 soot GPL to 2.50 GPL.
I completely AR'ed on the way to get fuel the other day.
EGT4 made it back down to around 700F as I pulled into the station.
Shouldn't be due for another until after I get fuel next time but it will be tomorrow morning at this rate.

Humidity has been very high here lately.
Could that have such a major impact?

Or, did I get crappy fuel at the station and pump where I always get my fuel?
Same station and pump the last 12 fillups in fact.

Last drain was 22 July with an A+ report.
Just took another sample and letting it sit but it looks good.
A few black speks but they aren't metal so that's good.

It's probably nothing but the Edge CTS provides info and it's in my nature to investigate and ask the experts.

Thanks.

 

Kyper05. You in the same as me. So consistent since 12b33 soot count rarely gets below 1.22 and hauls butt to 2.65 to where regen starts all over. About 90 to maybe 95 miles.it is not your fuel. Mine went down the toilet instantly.i know several that have confirmed same situation.

 

Soot has been climbing like crazy lately for me 60 miles then regen

 

I am having that same issue. My edge insight CTS says average miles between regens is 263 miles. I do not drive my truck as a daily driver. So when I do drive my truck it is normally for quite some distance. I go to the dealer tomorrow for some other issues so this will be brought up.

 

I'm on my 7th tank fill since the flash and I've never seen the soot count behave like this since I purchased the edge last year.
The first three tanks after that flash were crap but MPG has leveled out to about .2 to .4 or so less average MPG than prior to the flash.
For example, I was getting 13.6, .13.7, 13.8 and now it's 13.2, 13.3 or up to 13.5.
That's local driving (town, city, back roads, etc.).
I'm sure that equals to several dollars by the end of the year but I haven't worried about it much.
Nothing I can do about it.

The low count may have been 1.24 now that I think about it but that doesn't really matter.
It always gets up to around 1.80 quickly but then takes awhile to get to 2.66.
It was counting up so fast today I kept checking my boost to make sure the turbo was alive.

 

My average regen miles on the Edge never moves off 307 which isn't correct.
So, I say it's broken.

 

Mine has moved since I installed in and it is always around 250 to 275 since the recent NOX recall update.

 

Seems to be a lot of this going around! I am glad to hear that I am not alone, but I sure would like to find out why. I have just under 32,000 miles on my truck and it has never been flashed since it left the factory in late September 2010. I was hoping that it was related to the NOX recall, but some of you guys seem to have already had that done and still have the issue.

Am I seeing something that isn't there or all the guys complaining of this problem short trip, city driving or infrequent drivers? I feel that the problem is DPF related and I am afraid it is a function of my short daily commute and the lack of towing the 5th wheel this Summer. Pay attention to the exhaust backpressure throughout your complete regen cycle.

I will be taking my truck in for this and a few other minor issues next week. Hopefully they come up with something, but I'm not holding my breath!

 

Yesterday for example, after regen and final soot count ended at 1.26 on highway in 40 miles i was up to 2.06 so i know it wont take that many more miles and regen again.right on time.90 miles.has never been like this till that lousy tsb. Having had 2 of these trucks i have learned the normal.and this is not acceptable.

 

My truck has been going into regen at about the 50 to 60 mile mark. Last Friday I got the "Drive to Clean" message so I took a break from work and went on a drive while the system cleaned. The next day, about 60 miles later it went into cleaning mode again and again the next day at 50 miles. I do alot of stop and go but come on. Every day? I gues I need to call the dealership as I only have 2000 miles on the truck.

 

My truck is sitting at 2.63 now so I'm going to go out of my way during lunch in a few minutes to regen this thing.
Two stop signs and two traffic lights to get to an open road and it will start before I get through all of that so I'll probably end up in the 1.30's.

What tests can a dealer run over a help request like this?
I don't know how to approach them if this turns out to be the new normal behavior for my truck.
I can picture the "you have crappy fuel" conversation occuring.
My fuel filters are only about 7,000 miles old.

 

Since I've started doing most of my town driving (about 90%) in the tow/haul mode, the regens are fewer and mileage has actually gone up a little. Mine was doing a regen nearly every day and in less than 100 miles. Once I found out that it's OK to drive in tow/haul as much as I want without doing any harm to the tranny, I thought I'd give it a try. Maybe the higher average engine rpm is keeping the soot lower. I need to get an Edge and watch it closer.

 

I thought it was fuel quality at first also as for about 3 tanks prior to this starting I had not run any additive. 99% of my fuel comes from the same source, but I confirmed it was not the fuel source when we went camping a week ago and I filled up at another known good source. Also, no amount of additive has made any difference.

One thing that I did have occur near the beginning of this saga was #1 injector dropping out. At the end of an active regen, I had stopped but had not put the truck in park. Just as the light on the Insight went out, the truck started to miss. I pulled out from where I was out onto a local road and the truck continued to shake and miss. I stopped again and checked the DTCs. Don't remember the exact numbers but I had 2 codes, Misfire detected and #1 Contribution. The truck continued to miss until I cleared the codes. Immediately #1 injector started to fire again and that has not happened since.

We took a camping trip of about 220 miles back in the middle of June and I thought then as we crossed a few minor mountains in Western MD that the truck felt down on power. Fuel mileage with the 5th wheel seemed off a little as well being down to mid 11s from the usual mid 12s with that trailer, but I figured part of that was from being in hill country. Until this last tank of fuel, my unloaded economy has been about normal and my EGTs all seem to be what I consider normal. Something is definitely up with this truck and I hope it is not the beginnings of another 6.0 saga!

 

Soot count peaked at 2.74 and finished at 1.35 today.
It was 1.38 by the time I parked at the office and EGT4 was around 580F.
I'll see how fast this next round goes. I've only made it a quarter of a tank.
Computer was at 13.8 MPG prior to the AR and forgot to look after.

I spend a lot of time in manual mode with shifts between 1,500 and 2,000 RPM.
It's a habit I can't break back when [D] was too painful to use with the transmission shift issues (since fixed with the new solenoids and this flash 30,000 miles later).


Did the dash report anything (CEL?) about the loss of injector 1 or did you discover that thru the CTS?
I've never looked at the DTC screen on the CTS. There hasn't been a need to.
I need to do that to see if anything is reported.

 

It will be as anything the more people complain then they work on what went wrong.
