Baby's first Regen frustration 😡

[SeanPwnery]

I've had my rig now for about 26 months and 9,000 miles - I'm in the neighborhood of about 1155xx miles. Today was the first time since I've taken ownership that I received the "Exhaust System Regeneration in Process Exhaust Filter 80% Full" So, this happened half way on my way to work, which is about a 10 mile trip, and to be honest, I can't really divert and take it on a little road trip, so I thought I'd just wait it out, and give it attention on the drive home a different route with highway driving.

Well... I live in the 4th largest city in America, and with that comes the 4th largest rush hour traffic in America. I decided since I couldn't really get over 50, I'll just use the buttons on the wheel and keep the transmission in 5th so I'm turning about 2000 rpm at 50mph. Now keep in mind, I never got any "lights" on the dash since I thought 4th gens have an icon light too - I only got the message in the center display. Long story short, I ended up driving 90 minutes, going home, turning around going back down the farm roads behind my house, turning around, etc etc - with traffic, with a few red lights.

The message never went away. I assume there's a "Complete" prompt eventually, but I never saw it. So I guess I'm driving my 300S for a couple days until I can get it on a legitimate highway, on a weekend, in 8th gear doing 70 for a while.

That full delete is looking a lot more appealing now.

You know what would have been nice? A PROGRESS METER like the instant MPG one to let you know how much longer you should be going. If I needed 3 more minutes at 2000rpm before I threw in the towel tonight, I would have made one more lap.

So after poking around, it appears there is an actual progress update on the display (watched a few people go less than 5 miles and it dropped 10% twice on their displays) ... I guess I will have to get it on the interstate more than 50 before it starts ticking down.

I had that problem all the time while down south in MX where I could not drive over 50 mph! So I would run it in a lower gearing with manual shift button on the steering wheel and keep the rpm at 2,200 rpm I could the burn done in about ten minutes.
Having the EDGE ll is also a great help as it tells you when the burn is on and off and you can initiate a full burn with it if you need to.
I have since done the delete finally and should have done it years earlier what a difference it made! (Stage one only as I am only interested in best mileage). No turbo lag, actually accelerates at HwY speed to easily pass and averages ( real mileage not from dash meter) 31.5 mpg Imperial.

Wow... I'm definitely doing something wrong, I barely make 15 but, it is a lot of stuck in traffic nonsense too

It took 18 miles, but it finally did the regen. I had to get it up over 70 in 7th before the progress started ticking down, but when it started, it came down pretty quick. It crept up to 90% on the way to fill up before getting on the Interstate, but at least I'm not sweating the display now. It dropped down to 30% then afterwards it said "Regen process complete" ... as if the last 20% didn't matter or took nearly no time at all to finish that last bit. I wonder if I'll get another nearly 9k on the clock before the next one.

I would only get about 120 km in town driving in MX before having to do a burn about every second day!
Normal HWY burn was always been around 500 km starting at 65 to 70 % soot level and would drop down to 10 % soot level ( from the EDGE II readout).
Anytime I would go over 75 % level I would stop, initiate a burn cycle on the Edge II shut off and restart the engine which then immediately go to regen mode and burn that carbon out down to 10%.

Short update : So oddly enough, a little over 300 miles later, I received the Regen 80% full message a second time. This time I was able to run it down the Interstate and have it do the whole thing in 1 trip - but I found it a little strange that it came back and did another one so quickly.

 

[Bob S.]

That’s pretty close to what my truck was doing all the time on HWY runs normally (500 km or 310 miles) and that's how I believe it was designed to work. Starting the burn between 65 % and 70% soot loading.
As I had indicated if you cannot do delete then the EDGE II system is well worth the money for ease of mind and allowing you to initiate a full burn if for some reason the system is not initiating before 75% soot levels are reached.

Third regen in less than 2 months - maaaaybe 800 miles.... normal?
I'm starting to wonder if this is happening suddenly because I tried a cetane booster - add a couple ounces for a tank kind of situation. Usually I just run Howes Meaner-Kleaner but I thought I'd give this other stuff a try. I used the last of it last weekend, then here we are 4 days later waking up to a regen message again. I can't recall exactly if this started with that stuff, but the coincidence is a bit uncanny.

I had a lot of regen issues caused by my cat temp sensor failing. prior to this 260,000km never had a regen warning and since I changed the sensor no issues. every 300 miles or so sounds about right. When I was struggling to complete regens I would put on cruise control roughly 60mph and gear down to bring my rpms near 2500. driving slower allowed me to avoid having to ever hit the brakes which pauses the regen. dropping below I believe 1700rpm does also. it doesnt take long to complete a regen. I've done forced regens parked in my driveyway with 120% blocked down to 10% in roughly 10 minutes or so.
