It's really hard to tell on this rig without a reader. Mostly you’ll notice it if you're watching your instant mileage drop to around 10-12 sustained. Regens on mine seem longer at 550-600 miles. They are very stealthy, as they should be. I wouldn't worry about it too much, you'll get one per tank or thereabouts.
I tracked almost every one on my previous diesel by watching/hearing the rpms tick up, watching fuel mileage, sluggish power, and seeing white soot/ash come out the pipe, sometimes a Sulphur smell if the conditions were right. What did it get me for my effort......a long gawd damned list.
Lots of fear mongering about plugged DPFs and short tripping. That was mostly an issue from 10-14 models when it was new tech. If that was a real problem there be a truck on the side of the road every 3 miles around here. It's very unlikely you'll have DPF issues on late model rigs.
Drive more, worry less!
