Drive until exhaust is clean

Yes! This just means you're in active regen. It's part of the emmissions control system and is normal. You can keep driving if you want to, but it won't hurt if you stop (reach your destination) while it's in progress. It will pick up where it left off when you drive again. Look in the diesel supplement of your owner's manual and it explains what regen is and the difference between active and passive regen. You'll probably notice your fuel mileage drops off at the same time. That's a downside, but it goes with the territory.

I get it and its a pain. Seems to take way longer to get out of regen when I receive this message as opposed to the cleaning exhaust system message. I end up driving an hour or so once I get this message in order to ensure that the regen cycle is complete. I'd suggest not immediately parking your truck if you're in regen. Let it idle in park for awhile or just keep driving until the cycle is complete. This way, you won't get oil growth.

It is normal and it sucks.

A couple of bolts and hangers and as little as $800 and you will like your truck a whole lot more. I am not mechanic and I did it myself. It is easy and there is alot of info right here.

Mine ALWAYS kicks in 1 mile before my destination - Murphy's Superduty Law #38.

Do a search on the forum. I think someone said when you put it in Park it stops the regen mode(?), but you should let it idle down for a bit to burn the excess fuel out of the exhaust chambers? That sound accurate to people who know better? I'm going off memory of what I read somewhere on her a few weeks ago..

Drive to clean exhaust shows up if conditions have prevented the normal regens to start by itself for a while, or, previous driving conditions didn't allow the exhaust to get hot enough long enough to do any good....meaning the DPF is getting full and it's way overdue.

I find that if it's cold outside and I'm just driving around town while in regen, it'll stay in regen forever. The only way is to get it out on a long freeway drive to get things hot.

Regen once started on me just as I crested the hill on I-80 going downhill from Reno towards Sacramento. It's something like a 6Kft drop and my foot was off the pedal most of the time. Needless to say, I was blowing white/grey smoke for over20minutes all the way down since it was 30F outside and the exhaust never got hot. It was so annoying I used it as an excuse for a pee-break at the first exit to shut the stupid thing down.

My latest trick is putting the truck into neutral or park while at a stoplight to shut down regens if I know there's no chance I can get onto the freeway any time soon. That delays regen for a few minutes. It works for a while, but eventually, it'll restart as soon as you start moving again. Annoying to say the least, but it's better than watching my fuel gauge drop while trying to regen in futility in stop-and-go traffic. I let it do its thing once I know I can drive above 40mph.

If I'm in regen, I'll also throw the truck in park or neutral at a stoplight a few miles before my destination. That'll shut regens off and let things cool down by the time I get there. Did I say 'annoying' enough? Geeez....
