ISL DPF, frequent regens
Our 2007 ISL 425 with DPF (no DEF) has been doing frequent regens on this trip. Previously we would get a regen maybe once in a 7,000 mile trip. This trip, we've had two in the first 5,000 miles. In the past few days of traveling, we have gotten a regen daily and past two days, regens twice in 300 miles of travel.
Last year I got a DPF warning light and had Cummins check the system. They found a loose exhaust gas pressure sensor. They tightened it, checked the system and said it was OK. The service manager did say in his opinion, I would need to replace the DPF in the near future. He said in his experience with motorhomes, cleaning the DPF was rarely worth the money and replacement was the better option.
Anyone else have similar issue?
