I'd assume this vehicle is still under warrenty, have you taken it to the dealer? Might be a glitch in the software or system. Have them check the soot and ash levels. You don't want this to go on for to long, or DPF could become full/plugged. But, yes...take it out for a nice half hour drive at highway speeds...weekly...this will help immensely.

Yes, emissions are only going to get worse over the next few years for diesel engines. I primarily work on mid-duty diesel engines; Cummins, IC, Detroit, Cat, etc. So, l'm not that familiar with this engine of yours. But, l would assume it has a predetermined set of parameters that have to be met to do a passive regeneration (regenerate while driving)...and you're not meeting those requirements. Do you know if they are at least doing a forced regen, when you take it to the dealership?

Oddly, we use to tell our fleet drivers to drive cautiously...but since the introduction of DPF systems (Diesel Particulate Filter)...we tell them to "drive it like they stole it". Idle time is a killer for these systems, too. Try and avoid idling at all cost. If you do have to warm up the car, because of low ambient temperatures, raise the idle slightly to a 1000 rpm's (after a couple minutes, making sure to get adequate oil pressure). This will help some, diesel engine are the dirtiest (creating soot), when cold and idling.

If this issue persist, l'd definitely keep after the dealership for assistance. Keeping a record of this issue will help you in the future, when the system becomes completely plugged. Let them know that you are driving it for longer periods of time, without seeing any change.

Personally, and l know this doesn't help you at all, but l wouldn't buy a diesel engine in any vehicle that l was going to drive in a commuting fashion. Not unless l was driving it on the weekends to a cottage 2 hours away, every weekend, expressway driving. The savings in fuel mileage doesn't justify the cost of DPF issues in the future, if the vehicle isn't driven enough to cure DPF issues. One serious DPF issue...and there goes your entire fuel mileage savings for the ownership of the vehicle.

Anyhow, good luck.

I know it may be difficult...but is it possible to go to another dealership. We had a terrible time with a dealership, vehicles going there five or six times for the same issue. Eventually switched dealerships, which meant driving twenty minutes longer, and issues started getting repaired first time.

And yes, keep taking it back for repairs and site the "lemon law"...since you are driving the vehicle as expected, or no different than friends that have same vehicle without issue...but you are having issues. Something just doesn't add up here, and it would seem to me...that there is a problem with your DPF system. When you take it in next time, ask them for a printout of the codes they are finding and for all past history. Start building a document for future protection. Records will be your only saving grace, increase you go the "lemon law" route.
