Looks like I’m heading back down the regeneration slide again. The truck has been flawless since November of last year. 7 months straight with only a 24 hour regeneration and no soot load registering on the dash. Fast forward to this week, I’m 424 miles since last regeneration and over 25% on the gauge already. Same drive cycles, same speeds, same routes, same fuel, same filters, same driver, same fuel station…….literally every factor the same except that the weather has been getting warmer.

The truck didn’t miss a beat over the past 7 months and now it’s climbing like this for the second straight week in a row. Almost like it’s starting to repeat the same regeneration cycle stuff it did back in July of last year.

I consider myself very well versed in these systems and the operation of the truck generally, but this regeneration system has me utterly baffled. I fully believe there’s a malfunction somewhere, but finding it is going to be difficult
