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 commute is stop and go back roads 25miles each way. 26-32mph average speed usually, according to the trip meter. Because of this, I expected to be on the worse end of the regen frequency spectrum.. but I would have guessed 400-500 per.
So my car doesn't currently have any codes thrown, but this seems like an outrageous amount of DPF regens. I'm worried something will finally rear its ugly head after my warranty runs out.
I had also just gotten myself a Trifecta tune, which I have removed after 2.5 days of use. I am certain it was not the cause, but I want to address this problem before I add in the variable of an aftermarket tune. If it's relevant: when testing out my new tune I didn't notice a huge difference, and I couldn't get the instantaneous horsepower reading to break above 110.
History on the car: I bought with a note in the carfax that it had been taken in for "engine computer issues". I bought it in late August '15 with 550 gal fuel used and 16.9k miles (30.7 mpg average, I've averaged 36.7 mpg for my ownership). It threw a CEL on me twice; once in December and again in February. When I checked the code through OnStar they were quite vague (I don't remember the specific code). By the time I could take it to the dealer the codes had cleared themselves.
I've run 3 different diesel fuel system cleaners through the tank, replaced the tires with Michelin Premier A/S at 25k miles (didn't need tires yet, just unhappy with the stock ones in winter conditions), oil changes every 5k at the dealer. I plan to keep this car a long time and I don't intend to skimp or skip any preventive maintenance. I have a big service planned at ~30k: oil change, tire rotate, fuel filter, intake and cabin air filters, transmission flush and conversion to Amsoil atf. I'm strongly considering installing a Perrin air/oil seperator (best design I've seen so far, by a fair margin).
I also noticed when I checked my oil dipstick today, after driving about a mile to the gas station on my lunch break, that little puffs of what looked like exhaust.
Am I screwed and experiencing massive blow-by? Is the EGR going crazy and causing poor combustion and clogging my dpf? Is my high pressure fuel pump not running at proper pressure? Soot mass sensor malfunction? All of these are just guesses but needless to say I'm pretty freaked out.
I plan on dropping it off to the dealer, but honestly they don't give me the impression of being experts on our rare LUV engine. Anyone have any ideas of where to look first?
TLDR: Regens waaay too often, possibly low power, no check engine codes thrown. I take good care of the car, don't drive like a feind. What gives?
