This thread was started in January. It will be August in a couple of days.

I feel empathy for the few guys that are having these problems but I think we would have hear more if it was very widespread.

I personally haven’t had problems with the regeneration system. I purchased my truck in December and only have 11,500 miles on it but they are mostly stop and go miles which is a worst case scenario for DEF equipped trucks.

Good Luck...
