Hey all, Have a 2020 6.7 with 37k miles. About 10 days ago got a check engine light with code P2459- Frequent Regen. My truck had been running a Regen about every 25 miles. As soon as one would end another would start. My driving is about half highway and half local road. Dealer ran ECM flash 18-012-21 Rev B which took care of the indicator light but Regen still seems to frequent for my liking. It was running a Regen about every 100 miles today with mixed highway and local driving. What is everyone else seeing? Do I need to have DPF pressure sensor checked? Dealer seemed satisfied with ECM update but I’m not convinced.
