    My Cruze has been awesome in its first 10k miles but lately has developed some weird behavior. In the last 700 or so miles its done five regens, or what I assume are regens. In each case when I come to a stop at a light or elsewhere the idle surges very noticeably. This always coincides with the...

    I can always tell when the car regens as it starts to buck and jerk around most noticeably at lower rpm/slower speeds. This is accompanied by my boost gauge showing wildly jumping values from boost to vacuum and back again. Anybody else have this happen?

    I've recently started using another fuel station (Petro Canada) instead of the one I've been using practically since I got my Cruze brand new (Esso ((Also in Canada)). I still have a bit more testing to do, so to speak. My distance between regens, as monitored via my ScanGauge, have been cut in...

    This started after the recall last December to replace nox sensor and flash ecm. During regens the car bucks and runs rough, it will usually throw a CEL (2453 pressure sensor) I cleared the codes myself a few times and tolerated the rough running. In June I took it in for the CEL 2453 and they...

    A Lil history here: 2015 CTD with 4500 miles. I started getting frequent regens about a month ago. SC II was revealing frequent regens at less than 100 miles between regens. I was literally getting regens at 60-70 miles between regens. No tune, just totally stock CTD running BP or Shell diesel...

    I have a 2014 CTD with 28.3k miles (bought used with 16.9k). I just recently got myself a ScanGaugeII and it says I have 158 total completed regenerations... That's 179 miles per regen over the life of the car! My most recent distance between regens was 63 miles. 102 for the one before that. My...

    Took the CTD out Sunday to finish up a regen, no big deal until I get a call this morning from my wife saying the fan is running again. Last time I looked around for stuff with the scanner it told me that regens were a gearing about 775 miles, the most miles I can come up with this week are...

    Has anyone else noticed this? The last two times that I interrupted the regens first at STM 11 and second at STM 19, the regen process did not resume when I restarted the car. The STM gradually built back to 22 with normal driving and then restarted the regen. I think this makes more sense...

    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...

    Has anyone noticed a different frequency between regenerations when switching fuel brands? I was going close to 500 miles between regens with Hess diesel, however since they were bought out by Speedway the last three regens have been around 175 miles. Maybe my driving has changed. I'll try a...

    Decided to time the intervals between regens the last 3 weeks.. They seem to be fairly predictable now.. First was 18 hours and 40 minutes, second was 18 hours 25 minutes and today was 18 hours 45 minutes.. Not sure if it's different for more city driving but for me it's a 65 minute drive to...

    Hi, My commute is about to go from 35 miles, mostly interstate, each way to 2 miles in town. I've read the stories about the DPF getting clogged up with these kinds of commutes and by the time the "Keep Driving" message comes up it is sometimes too late. Of course this is the internet so you...
