The whole Regen system is a pain. I never let def go under half a tank in my truck and never had a issue. The day I let it get kinda low suffered a loss of power and bunch of other stuff with it went outta whack.

DEF levels in the tank have nothing to do with the REGEN interval.

Although I agree, it’s definitely wise to keep the level at or above “half-full”.

Guys and Gals, most of our trucks have manuals. At least familiarizing yourself with the various controls and systems found in the truck is highly suggested. If your assigned truck doesn’t have a manual, ask for one.

While the DEF systems in these modern day trucks can be problematic (especially on high mileage trucks), running your DEF tank below the half way mark has no I'll effect on the system. You had something else going on that day. I'm just pointing this out to keep some seemingly misleading information from becoming "factual" to other rookies reading this.

Now, had you been driving with that tank really low, as in empty, that could have caused some issues.

Speaking from my experience on that one. Wasn't necessarily saying it had anything to do with it just interesting that it got low, and caused issues. Roadside came out, and a def quality sensor caused me to derate. But when he checked the def it was fine so sensors were outta whack. Kept it over 3/4 of a tank and everything is back to normal not even a parked Regen comes up.

Being comfortable is important.

Now, that's good Chip Bagg. You have to be careful what you say in a place like this. Thousands of new drivers could take your earlier statement and falsely be thinking they can't let that DEF needle get below the halfway point or they're messing up their truck. Nobody's getting on to ya, we just like to keep it real in here. It is Trucking Truth after all. smile.gif

Thanks all. Regen warning and check engine light went away.

Good news Wind, what did you have to end up doing for it to go away?
