New engine teething issues?

[rickinAZ]

I have looked and I do not see any way to perform a forced regen without factory softwear. I would think the Tazer should be programed to do it but its not.

This is why I was asking about the forced regen:

Manual (active) DPF burn
If you’re more likely to do short hops to work or picking the kids up from soccer or getting the groceries, some manufacturers have added a manual DPF burn-off button. This essentially forces the vehicle to heat up quicker and begin a burn straight away. This is done by injecting raw fuel into your exhaust to increase temps high enough within the DPF to effectively burn the matter out, or ‘regen’. Undertaking a manual burn-off will allow you to do it on the way to work, instead of it automatically initiating a burn-off cycle while you’re sitting out the front of the kid’s school pluming smoke everywhere.

Here is the complete article. It's a simple read - good for folks like me.

During a regen there is no " pluming smoke everywhere " also there is no system the will allow a driver to perform a manual burn while driving. There are three types of regens. Forced that will require software to force a regen no matter the state of soot in the DPF, stationary that would allow the driver while sitting still to perform a regen only if soot levels are within the parameters set by the manufacturer, if it is not within the back pressure parameters it will not allow a stationary regen. Last is the passive regen. This is done by the ECM when soot levels cause the back pressure to reach the parameters set by the ECM to perform the burn off. If during a passive regen the driver stops, slows down to a set speed or shuts down the engine it will abort the regen and try again when parameters are met again. That is why it will ask you to keep driving. If you ignore the requests it will allow soot to continue to build up and then to protect the system and force the driver to take action it will start to de-rate the motor.

Stories about engines shutting down with no warning because the DPF is plugged are false. The system would not allow it to happen without plenty of warning.

There are a lot of people making statements about the DPF system that have no idea what they are talking about. They are very complicated systems and can be a head scratcher sometimes when they act up but they are made of some very high quality parts that do not fail as often as some say. The parts live in a world of very high temperatures, 1000 to 1500 degrees during a regen. The main reason most light trucks do not have the capability to allow the driver to perform a stationary regen is due to the danger of causing a fire if parked in or on something flammable. Imagine performing a regen while waiting for your kids to come out of school only to find out your sitting on a pile of leaves and end up burning your car to the ground along with a few others sitting next to you.

It’s still early, but there are far more folks running trouble free 3.0s at this point than not. Buy it and run it for a couple years under warranty. By then there will be folks pushing 100k miles with them and plenty outside of warranty for you to better understand whether to offload it before your warranty is up.

I've waited for mine for two years after it became obvious our 2016 2dr Rubi didn't have the room or power to handle towing an off road trailer (BoreasXT). We absolutely love this new Rubi. We have had at least one sensor problem with something about the humidity sensor that the dealer replaced. Not sure if that is diesel related or not. My biggest concern so far is the amount of DEF fluid we have had to put in. Have already added 5 gallons of DEF and we only have 3k miles on it. Don't know if the dealer put in more than 1 gallon because I didn't know where the DEF guage was. The guage is not a float like the gas/diesel tank but a sensor that predicts the amount you are using and projects the mileage. I had the 500 mile warning message come on, went another mile or so and restated the engine, message gat the 460 mile warning, went another mile and after a restart got the 420 mile warning. Freaked out and abandoned our Backcountry trip and made it to a small town and added my second 2.5 gal DEF at 2400 miles. Any thoughts anyone?

Dunn'o about your DEF use, but mine is SIPPING Def and at 4k miles is way less than my 2014 Ram Cummins. It's gott'a be all about how you drive and the computer KNOWS...
So far, I'm as happy as a pig in $hit with this diesel...wouldn't have it any other way.

Hey! have you got a Boreas trailer??? Man, I've been look at them and they look amazing! Wish I could see one in person.

Send me a PM about what you know!

I'm not a forum expert so not sure this message is personal or not. But my wife and I absolutely love our Boreas XT. We have had just over a year and have probably spent 60-75 nights in it. We got to meet Matt and his team that builds them as we had a few extras added on and they are a bona fide first rate operation. They are one of they few builders that have stock on hand so you don't have to worry if your build deposit may disappear on you like other companies we watched. We have taken it into some pretty remote areas mostly in 4 hi (which may answer my DEF consumption issues). DM me if you want to take this offline, since I obviously don't know how to do it.
