HELP: Cummins isx 15 REGEN Problem

Wow.

 

Mine doing the same. It was the filters. Even after having them baked they only worked for about 3,000 miles and rght back to frequent Regens. After so many miles they’ll read clean after a bake but will accumulate ash again really quickly. Use an after market DPF offline. It’ll save you a few grand

 

Did that fix the problem? The catalyst i am having the exact same issue as you guys and it has been two months. They have changed the turbo but not sure if thats gonna fix it. Thanks

 

My trucks having the same problem since two months and they couldn’t figure out what was wrong. They have changed the turbo now and hopefully that fixes it. Was your problem solved after the catalyst changed?
Thanks
