I have had the scanguage 2 monitor for awhile now (6 months or so) and have been watching my regens and soot mass frequently. Recently, the past 3-4k miles or so i have been doing a regen every 100-250 miles or so. I generally average 500-600 miles before a regen. I am just trying to track down what would cause the uptick. As of the date i have 18700 miles with 50 completed regens. My commute is 80 miles a day with 70 being at interstate speeds of over 70 mph. I have also been using the same fueling station, the fueling station is a rather heavy use station on a turnpike exit.
