I have been laid up after surgery - so my driving has been city - short runs to store, Dr. office etc. for the last 2 weeks - not what a diesel truck is made for...

I did drive to the ranch Friday & back sunday - about 50 miles hwy each way - so not sure why I didn't get a burn then..

So - Tues night - as I was turning the truck off I notice " Drive to Clean" message as I was clicking the ignition off - Too late!....

So this morning - I made an extended coffee run... I turn the truck on and even while in reverse the message "Drive to Clean" was on & off.. Then pulled out on the road - never dismissed the message and ran north on the intercity highway here... a few miles up - I assume the truck got to operating temp (or oil) and the "Drive to Clean" message changed to the "Cleaning Exhaust Filter" which usually flickers on for about 3 seconds in normal situations but stayed on this time.

I ran north for about 10 miles and circled around and went south - all the while I didn't dismiss the "Cleaning" message - just to see what happens in this scenario... Finally - about 8 miles later the " Cleaning" message turned off and the screen went to the regular instant MPG screen that had been on behind the message. I could have hit the "OK" button to dismiss but wanted to see what the truck would do...

I Just thought that I would post this for anyone who might be interested... Truck appears to be functioning fine and I assume did exactly what it was supposed to do in this situation...

 

That is what it is designed to do in that type of cleaning.

If you were to dismiss it and a few it would come back on again.

This is the only time that the message stays on.

 

Drive to Clean message happens when there have been several failed attempts at an active regen cycle. During the Winter months when I don't do much heavy towing, my truck is notorious for wanting to start a regen just as I arrive at my destination. If I ignore its need for a regen several times, I get the Drive to Clean message. She's just letting you know that she means business! Otherwise, active regen isn't that big of a deal to me.

 

Very good useful information thank you.

 

Thanks - I hope it helps those with questions...

First time it had happened to me...

 

With my type of driving I am surprised I haven't seen that message. I always get the cleaning message just before I get where I'm going. I guess it stops when you are in park. This is a pain. Should be able to direct it to do a burn when you want. I drive 50 miles on the highway and a half mile before I stop it starts a regen. Then stops when in park. Handy.

 

Corn. If yours I's starting 1/2mile it s hould start back after it gets warmed up next time leaving plenty time to. Clean in your next 50 miles.

 

It stops if you shift to P, R or N for 10 seconds or more.
It also won't start until oil is above 150°F.
I canceled two yesterday but the second time burned off enough where it wouldn't restart and probably will tomorrow or Saturday.

 

That option is available now with the Edge CTS! As mentioned, active regen stops when the vehicle is placed in Park. If the cycle has been active for a few miles and has heated the DPF up to 1000+ degrees, even after it stops dumping fuel for the active regen it will still burn off soot at an idle. When a regen has reached max temperature I can usually let the truck idle for upwards of 5 minutes until it quits burning off the soot. It isn't real healthy to just shut it down if things are that hot anyway so you may as well let it burn some soot and cool down in the process.
