DPF regens seem more frequent lately

CleanPilot15Community StarterJul 19, 20262021 Chevrolet Silverado 1500 LTZ 6.2California
2021 Chevrolet Silverado 1500 LTZ 6.2, about 37,000 miles. Truck is doing more short trips lately and I feel like active regens are happening much more often. No codes. Is there a good way to confirm soot load/regeneration frequency with a scan tool before assuming something is wrong? Appreciate any ideas on what to check first.

Owner notes beat generic advice here. On the 2021 Chevrolet Silverado 1500 in California, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “dpf regens seem more frequent lately,” that was the fork that mattered for me. If they can't show the line item, I assume it's hiding. If your situation is the opposite, ignore me. Wrote this up on my lunch break.

Fair point. Counterpoint: If it still isn't clear on the 2021 Chevrolet Silverado 1500, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. This is from a 2021 Chevrolet Silverado 1500 in California with 37,000 miles. Time, temperature, and whether it's in gear are the notes that actually help a shop. I'm keeping receipts and dates in one folder.

I'd keep this practical. Verify the cheap/easy branch on the 2021 Chevrolet Silverado 1500 before a big repair or a big spend. That's where I'd start. Verbal 'we'll take care of it' is not a plan. Doing the boring step first on purpose.

Write down what you already tried. A second data point from another 2021 Chevrolet Silverado 1500 owner helps more than a generic diagnosis. Then you'll know the next fork. This is from a 2021 Chevrolet Silverado 1500 in California with 37,000 miles. I'd want that in writing, not as a promise. Might be overthinking it, but I'd rather overthink than overspend.
