I feel your pain Josh! Just glad your brother was with you, that would’ve been very stressful having those issues with Mel and the kids onboard! The frustrating part is this is also happening to big class 8 trucks costing them thousands in repairs and downtime..
Your DPF is so clogged it won’t even run at this point. It’s clearly been an ongoing thing the whole trip but it’s went long enough at this point it’s totally choked out. I would start by removing the tuner and try unbolting the exhaust to limp it where you need to go. It should be able to breathe then. As far as fixing it, you’ll probably need to replace or “discard” that DPF since it’s gotten to this point. To me it seems like you may have a boost leak or something with the tuner that is causing the excessive soot buildup. I see this happen all the time on these trucks in stock form when the engine air filters are totally stopped up.
Josh there was a Recall from GM on some of the l5ps. It was a software update to increase the Regen Frequency. If you didn't get a recall I would visit your local dealer and have them check to make sure the ECM has the latest and greatest calibration installed. Also some had some injector problems that lead to the DPF plugging like yours is. If you still have issues after you had everything cleaned you may want to check into injectors. On a more positive note it looked like a fun road trip. I would love to do something like that.
i got that done second oil change around 12kish they said something about incorrect ecm files and i got the heater plug installed but not i got another letter saying to get the heater cord fixed again doesnt matter if i had pervious work done gm recommends it to ensure the plug works properly …..
@@mondo9.2.5 I think i've done about 100 of those block heater recalls. Both the first and second ones. Apparently the coolant is leaking through the block heater and into the cord and causing fires. Don't ask me but after building cars for over 100 years you think they could build a block heater. lol Yes it is a recall so it won't cost you anything.
Seeing this makes me think I need to delete my lml and say screw the warranty. I limped a lb7 with bad injectors twice before biting the bullet and replacing them. But seeing this I think an emissions related failure is far worse
That's exactly what I did on my 16' denali. Was throwing a nox sensor code with the CEL and was trying to regen constantly. Said f it and let some parts fall off (completely on their own, of course). Couldnt be happier. I'm already converted to cp3 so losing my remaining warranty wasn't a big worry to me.
Dam bro , It’s this type of crap that is my biggest fear on long trips. But you’re probably one of the better people to have on a trip like this. At least you know what’s happening with the truck for most part.
Nothing like seeing someone really happy and grateful about receiving a gift. I bet he's been sitting in his driveway staring right now. As for your problem. Well that sucks. The emissions on these things are marginal at best and the minute you do any mods you are rolling the dice. Unfortunately the days of the easy delete are in the past and your taking taking a chance with any go away products. Good luck.
So I have 110k on my 2018 GMC 3500. Most of my issues were do to the emissions system. My truck seem to regen a lot. My latest failure was number 5 injector blew up. I said the same thing about fixing mine the right way. Good luck Josh.
The old adage, "no good deed goes unpunished" applies here. Truly sorry for all the trouble you're having. I sense the issue started with computer / electronic issues and hope that it didn't lead to an actual mechanical failure. You're a good man Josh! Your subscribers / viewers will have your back, no matter what the issue is.
I pull a 37ft camper with my 06 lbz and i always run with tow mode on, shift points in your transmission are longer and it won’t let it downshift as often.
Hey Josh. Born and raised my whole life in Colorado. Us locals call I-70 the destroyer of vehicles lol. Driving that stretch countless times. If there's anything at all going on with your truck you'll know it out here.
I recommend 100% doing the weight reduction. The L5P is the strongest of the big 3 and has the most potential. The emissions Is the only thing that can kill the truck. Remove the Junk. I decided to get my truck fixed, and it has never been better. Runs like a top. The oil is no longer purely black at oil changes. It truly is a shame to damage the beautiful L5P by leaving the cancer on the truck.
@@ethanconard2178 it’s not a strongest. You not going to find duramax in school busses or mining equipment or farm equipment or box trucks, cummins only. Also, crankshaft balancer pin is the weakest thing and cannot found on any Diesel engine except duramax. That’s why duramax known for broken crankshaft
Really awesome truck give away. You broke down near my home town. I grew up in Gypsum, you broke down in Eagle, that’s where I met my wife. We have been married 25 years on Tuesday. I haven’t been bake there in years. Sorry you broke down, but thanks for the video, and some video of where I grew up.
I remember when my duramax left me stranded with a loaded trailer in Southern Illinois a couple years back, took 12 hours for my buddies to grab another truck and trailer to bring down to rescue me. Been chasing issues with her for almost 4 years now. I need to find a reputable shop to get it figured out, I'm at my wits end with it at this point.
Bunch of comments about deleting 🙄... That's not the problem right now. Right now the problem is the "upgrades" not playing nice with the emissions equipment. The white smoke is normally OK but not in that quantity. I think your tuner has a bug in it. It's making the ECU think that the DPF is clean when it's really not. That or your differential pressure sensors are bad and sending the wrong signals to the ECU. I hope you get it figured out soon! Sorry this happened to you so far from home 🏡 😢 Prayers brother.
@@repairvehicle Not always but very possible. Let's hope that for Josh's sake that it's not. If his truck weren't throwing all those DPF related fault codes at him the entire drive then I'd agree with you. The way the DPF works is when the upstream (before the DPF) and downstream (after the DPF) pressures are significantly different (differential pressure) it'll trigger the truck the go into DPF regeneration. During regeneration raw diesel fuel is injected directly into the DPF and exhaust gas tempos are raised to approximately 1,200 degrees which will effectively incinerate all the captured soot and convert it to ash. That's the entire purpose of the diesel particulate filter. That's why even a brand new duramax, Cummins or powerstroke will occasionally blow white smoke when they're in regen. The fact that he was blowing so much white smoke is because he's probably completely clogged his DPF. Evidence to support this is that his turbo can't even push exhaust through the intake because the engine is literally choking on its own exhaust. As a side note... the DEF is injected into the SCR (Selective Catalytic Reduction) chamber which is physically after the DPF chamber. If he was having a problem with the DEF fluid or otherwise having an SCR issue the truck would throw different codes at him.
My 2021 Chevy LM2 started having various DPF issues after around 16 months of ownership. Mileage countdowns to limp mode to check engine light. Drove almost 4 thousand miles round trip to California and back home. The dealership has replaced all the sensors and erg under warranty. It's now in for a leaking gasket. The best tip I can give is to unplug the negative battery port and leave it out of an hour or so, maybe overnight if possible, then plug it back in. Resets the computer. I'm waiting on the dpf delete tuner system to come to the market.
Point blank performance has a video on this exact problem. DPF failure had the soot pushing out the air box. The air filter was completely covered in soot as well. We can thank the EPA for this.
Struggling with emissions related issues on my lml work truck. Threw the cp3 and new head gaskets. Within an hr dpf full fighting every day and Decided to delete and tune. In the middle of that right now. Good luck
4hrs away from home pulling 12k camper trailer with my wife and kids aswell. My Denali Dmax same thing happened to me I started getting messages in dash abt reduced max speed after certain mileages tho! It was repaired to now breathe just fresh air! That same anxious feeling came over me that got you when it started messing up!
I had to get rid of my 2015 duramax at 102k after the third emissions break down resulted in the turbo blowing oil through the entire exhaust system. So sad because my 2005 with over 300k never had a single issue. Replaced the 2015 with a 6.6 gas gmc and haven’t missed the new diesel problems since!
Lost fuel pressure on my LMM in 7 degree weather at 3:30 am while pulling. Pulled off on the side of the highway, sent up a quick prayer and started thinking. Went to prime the fuel and the fuel filter started gurgling. Screwed the filter back on tight and got prime back. Being stranded sucks for sure!
I have a 2021 denali and the exhaust system has been giving me problems ever since it hit 14,000 miles. it has 22,000 now and I think it's time to take the mask off so it can breathe. God bless and I hope you make it home safe 🙏
that stinks, I have had the same thing happen to me as well on a cross country trip. was stuck in Johnson City Tn. for 3 days. hope you make it home safe and soon.
Have you returned home yet? My wife ended up in the hospital Sunday morning and I’ve been caring for her since getting home. I seen your video and it makes me ill to see you stranded. You have such a great outlook on life I would really like to help. I could imagine me driving out with my 2020 GMC Duramax and dragging your trailer and truck home. Just bad timing
Dang Man, I hate you had so much trouble. Romans 8:28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose. God will use this brother. Keep your head up, you sure blessed that Veteran with the build man. And you got to spend time with your brother too man.
The lower boost isn’t a bad thing you want more flow! I know on my LBZ after putting on bigger intercooler piping I dropped boost and EGT’s but it pulled harder for sure
Yep. I hardly haul or tow anymore so I went 6.4 hemi megacab 1 ton and I don't have to deal with emissions headaches. Gas towing ain't the same but no headaches.
Sucks happened that far away. I love my L5p without all the crap weighing it down. Decided to kick that stuff off at 2k miles and loving it every since.
Wow brother I’m so sorry about your luck man you are such a good person and this stuff has to happen can’t wait to see the next video hopefully you get home safe I remember the video where your other Duramax broke down on you and you had to tow at home with the giveaway truck looks like you been having problems with them hopefully you we’ll figure it out brother
That man was shocked that all this was actually happening to him. God bless him and you for building this truck and giving it to people like him whom really deserve it! This makes me want to buy a Diesel GMC/ Chevy now. I have a 2018 Toyota Tundra 5.7L Crewmax trd 4x4. I have a 2016 GMC Sierra 2500 HD Z71 4X4 and man do I miss it even though it was just a 6.0L Gasser.
Do an experiment with this truck when you get back home. Start putting water in the def tank and see what happens. Look into that and consider it. I should have tried it before we deleted a friends 6.7.
Your brother is a great wing man. I have. A 16 lml that’s fixed by the means you were mentioning. Hope it turns out ok and interested what happened. Hope y’all get home
This happened to me before I have a 15 dually dmax. I was hauling a 42 ft 5th wheel and this happened.. I was in grand junction took it to a diesel shop.. they just regen it they never found the problem told me I had a bust cylinder or injectors... I limp all bk to az.. .I park my truck for about 2 months.. that's where I found this channel.. but after watching all kind of diesel problem video. Finally got the courage to fix this diesel myself.. and did. I borrowed my brother's scanner.. I probe the egegg, nox, pressure , map, maf.. boost all them sensors..replace them all.. but the map was no good.. I probe check it. Undo the whole harness and there it was . The wire had cut open and it was green that's where it was shorting and not giving signal.. now it runs great. .but with the videos u do I learned what I know about this truck.. I know you'll get this girl back on the road.. and thank you for the video..
I have a 2019 Duramax with NO mods and pull a 15,000# 5th wheel and a 4seater RZR behind on its own trailer (Double towing) all over the high passes Colorado where I live and have never had a single issue
As for tow/haul mode, I run around with it on at all times, the shift points are way better, holds gears longer to let the engine work, and it locks the torque converter in 2nd gear instead of at 55mph which takes a lot of heat and out of the converter and reduces wear. And in my case, with having 37’s and stock gears (4.56’s are on the way) it makes a world of difference holding lower gears longer; 6th gear is so overdriven with 3.73’s snd 37’s that it’s unusable. So it actually helps my fuel economy because the engine is up in its power band and holding 12 pounds of boost, so the engine load is 20-30% doing 80 in 5th instead of 40-60% in 6th
CONGRATS JERRY! BUT MAKE SURE YOU COMPLETELY TEAR IT DOWN AND MAKE SURE THERES NO RUST BECAUSE IT DID COME FROM MICHIGAN! ALSO MAKE SURE THERES NO MECHANICAL ISSUES WITH IT BECAUSE AFTER WATCHING THIS VIDEO ILL BE CONCERNED!
I would have unplugged the chip you installed on top of the ecu and put it back to complete stock. Not knocking any aftermarket parts but I’d leave well enough alone. My work has 2 duramax trucks and both have cost us close to $80k in 4 months in fuel related repairs. Anyone can guess what failed.
@@repairvehicle that's true, my coworker never let's his powerstroke regen and it's a grocery getter and only runs around town stop n go..then it goes to the dealership for a week. 🤦♂️
If you need a truck to get you home let us know! If you're still stuck in CO, I'm right up the road. You can take my Cummins. Ill be in MN next week to pick it up!
I drove a Dodge Cummins six speed for 15 years. Just ordered a 2023 GMC with a 6.6L gas 6 auto. Have three tractors and a Cat excavator..... no DEF on anything.
I’ve been thinking about buying a new truck lately but couldn’t pull the trigger. This video just answered all my questions. I’ll keep my old 08 Silverado and just keep upgrading her.
I never seen this channel before and this is the first video I seen, live a hr west from the Colorado sign you stopped at in a little area called Ft. Duchesne. I’m sure you will remember the trip for a long time and I’m glad you got home safe. Also the giveaway was awesome and congratulations to the lucky winner.
I have a 2017 Ram 3500 Cummins with the Edge Juice. I live in Colorado and we travel on I-70 up and down the mountains. With my Cummins it will sometimes defuel me and the torque management will kick in when I am hauling our 16k lb fifth wheel toy hauler. It only happens every now and then when I am on level 3 or higher. Yes, I only use level 4,5, or 6 for very short bursts. Then again that is even a bad idea. But hey it’s my truck.
Them l5p must be bad for emission issues my co worker has a 17 duramax that is having a lot of the similar problems. It's just so annoying that the factory spends 1000s on putting on those parts so we have to spend 1000s to get rid of them so we can actually go somewhere without worrying that were not gonna get there.🤯
This almost smells like a fuel rail issue. They have a big problem with the pass side rail and connector having issues. If you watch your rail pressures. Fuel rail pressure 1+2 should be near thier desired. Any deviation by more than a couple hundred psi.. there's an issue. Also they have injector and injector connector issues. Also the fact you threw a mass air flow code makes me think you might have an issue there or you have a boost leak somewhere. The other big issue they have issue the def injector getting clogged and causing regens to be a massive pita. Im a gm tech by trade. If you want to work with me directly. Hit me up.
I may be wrong but I’m pretty sure Tow/haul doesn’t result in more torque. Its purpose is to increase line pressure in the transmission and adjust shifting to reduce friction and heat in the transmission while towing.
Have you replaced your DPF? I think that could be a major issue since it is emissions compliant and it now has 100,000 miles on it. (This is based off of what I learned in my Automotive class that I took in high school. We didn't go over much because they don't deal with them)
Say your adding windmills to the engine, and replacing the drivetrain with child labor lithium/Ukraine biden batteries. Youll prolly get a nobel peace prize.
It’s your tune, it keeps truck running reach and generating more soot. Tune is a death to the engine. Manufacturers spend millions on testing making sure everything works fine. Tuning software companies spend no money on testing, you just get unreliable power and problems later. With factory software truck is happy and regeneration happens automatically on highway driving specially with load.
thats why i leave my lly alone 05, 200k and going strong. you do not need all that horsepower nor torque u still cant haul more than the manufacture says. why do that to ur truck, all that money for something you dont need in the first place.
@@MRW21783 well not me i have the lly, but i work for a local gov and our fleet is going back to gas engines due to the regen bs on all the diesels.. who ever the idiots at the epa were that thought emergency vehicles would be fine with the regen are truly ignorant college dummies. hope im not in the back of an ambulance when it goes into limp mode for regen what a bunch of idiots. im keeping my lly no issues

I'm waiting on the dpf delete tuner system to come to the market.
Be glad you were not in Oklahoma. If you break down in Oklahoma, it is a vortex where you can never leave unless you get towed out of the State.
Checking in from Iowa hopefully you made it home safe and sound. my brother also has a l5p duramax midnight edition 2018 and he never had this issue
Point blank performance has a video on this exact problem. DPF failure had the soot pushing out the air box. The air filter was completely covered in soot as well. We can thank the EPA for this.
Nice try fed boys
Whether or not any of has served we are all Brothers and Sisters! Plenty of family with us that did. Cheers dude! Enjoy!
You have a amazing program. You made his year. God bless you for your service and your generosity!
Struggling with emissions related issues on my lml work truck. Threw the cp3 and new head gaskets. Within an hr dpf full fighting every day and Decided to delete and tune. In the middle of that right now. Good luck
4hrs away from home pulling 12k camper trailer with my wife and kids aswell. My Denali Dmax same thing happened to me I started getting messages in dash abt reduced max speed after certain mileages tho! It was repaired to now breathe just fresh air! That same anxious feeling came over me that got you when it started messing up!
It’s definitely not fun to go through
welcome to using a Pulsar tuner. Should have used the Banks Derringer, Gale is the king of diesel tuning!
I had to get rid of my 2015 duramax at 102k after the third emissions break down resulted in the turbo blowing oil through the entire exhaust system. So sad because my 2005 with over 300k never had a single issue. Replaced the 2015 with a 6.6 gas gmc and haven’t missed the new diesel problems since!
Carbon build up issue is around the corner on these engines, it’s not 6.0 gas that were proven to be reliable
Lost fuel pressure on my LMM in 7 degree weather at 3:30 am while pulling. Pulled off on the side of the highway, sent up a quick prayer and started thinking. Went to prime the fuel and the fuel filter started gurgling. Screwed the filter back on tight and got prime back. Being stranded sucks for sure!
Just give it the “Weight reduction” exhaust
I have a 2021 denali and the exhaust system has been giving me problems ever since it hit 14,000 miles. it has 22,000 now and I think it's time to take the mask off so it can breathe. God bless and I hope you make it home safe 🙏
Mask prevents soot from escaping but hot exhaust gasses. Allow truck to regen and all your problems will go away
that stinks, I have had the same thing happen to me as well on a cross country trip. was stuck in Johnson City Tn. for 3 days. hope you make it home safe and soon.
This is exactly why I’m hesitant on buying a newer truck. Good luck. Think we’ve all been stuck ain’t no fun
I have the same problem with my diesel particular filter. The dealer says Chevy is aware that it is an issue at high elevation and when towing
Hi Josh I just hade the same problem with my 2017 L5P 56K on it. I blamed Michigan cold weather. I will be fixing my truck in to weeks.
Those new trucks are luxurious but I'll take my 2004 lb7 3500 with no emissions.
Man Josh I'm really sorry you had such a bad trip , hope everything works out for you brother
Thanks Rex
Have you returned home yet? My wife ended up in the hospital Sunday morning and I’ve been caring for her since getting home. I seen your video and it makes me ill to see you stranded. You have such a great outlook on life I would really like to help. I could imagine me driving out with my 2020 GMC Duramax and dragging your trailer and truck home. Just bad timing
No wonder Chevy didn't do the commercial of "like a rock" anymore...GM products will leave you on the side of the road LIKE A ROCK!
Dang Man, I hate you had so much trouble.
Romans 8:28
And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
God will use this brother. Keep your head up, you sure blessed that Veteran with the build man. And you got to spend time with your brother too man.
mine did the same thing, dpf filter was clogged, ended up (---) it and runs amazing
👌
The lower boost isn’t a bad thing you want more flow! I know on my LBZ after putting on bigger intercooler piping I dropped boost and EGT’s but it pulled harder for sure
My LML did the exact same thing towing a skid steer home. Clogged filter then coolant hose to the EGR valve blew all my coolant all over my engine
If I were a gambling man I'd say that edge pulsar was the culprit
It might be
Anyway to pull it while on the trip and go back to normal just for the trip.
Man that sucks bro I really really hope you can get that fix soon brother 😢😬😬
These new diesels have so much torque and HP I wouldn't add a tuner, in the past yes..nowadays no.
OLD TRUCKS RULE!!!
Hopefully you're covered under warranty still josh. Best of luck!
There’s no way he’s covered, unless the dealer is cool.
No warranty here
Trade that dmax off for a gas HD/SD. You need something reliable for a long term truck, and todays diesels are not reliable. Great video.
Yep.
I hardly haul or tow anymore so I went 6.4 hemi megacab 1 ton and I don't have to deal with emissions headaches. Gas towing ain't the same but no headaches.
@@MrStaybrown Yessir, I'll be upgrading my 15 1 ton 6.2 to a 7.3 with 4:30 gears. My semi convinced me to go gas.
@Mrstaybrown You still have emissions junk...just not as much
Sucks happened that far away. I love my L5p without all the crap weighing it down. Decided to kick that stuff off at 2k miles and loving it every since.
Any recalls or warranty repairs will not be done by the dealer
The ol' sadstance thumbprint!! 😆 🤣 😂
That is my biggest concern about buying a new truck. My 2015 LML that I bought new eight years ago runs good. As you mentioned, “I fixed it.”
Wow brother I’m so sorry about your luck man you are such a good person and this stuff has to happen can’t wait to see the next video hopefully you get home safe I remember the video where your other Duramax broke down on you and you had to tow at home with the giveaway truck looks like you been having problems with them hopefully you we’ll figure it out brother
That man was shocked that all this was actually happening to him. God bless him and you for building this truck and giving it to people like him whom really deserve it! This makes me want to buy a Diesel GMC/ Chevy now. I have a 2018 Toyota Tundra 5.7L Crewmax trd 4x4. I have a 2016 GMC Sierra 2500 HD Z71 4X4 and man do I miss it even though it was just a 6.0L Gasser.
Do an experiment with this truck when you get back home. Start putting water in the def tank and see what happens. Look into that and consider it. I should have tried it before we deleted a friends 6.7.
Your brother is a great wing man. I have. A 16 lml that’s fixed by the means you were mentioning. Hope it turns out ok and interested what happened. Hope y’all get home
Time for a “permanent fix”
This happened to me before I have a 15 dually dmax. I was hauling a 42 ft 5th wheel and this happened.. I was in grand junction took it to a diesel shop.. they just regen it they never found the problem told me I had a bust cylinder or injectors... I limp all bk to az.. .I park my truck for about 2 months.. that's where I found this channel.. but after watching all kind of diesel problem video. Finally got the courage to fix this diesel myself.. and did. I borrowed my brother's scanner.. I probe the egegg, nox, pressure , map, maf.. boost all them sensors..replace them all.. but the map was no good.. I probe check it. Undo the whole harness and there it was . The wire had cut open and it was green that's where it was shorting and not giving signal.. now it runs great. .but with the videos u do I learned what I know about this truck.. I know you'll get this girl back on the road.. and thank you for the video..
I have a 2019 Duramax with NO mods and pull a 15,000# 5th wheel and a 4seater RZR behind on its own trailer (Double towing) all over the high passes Colorado where I live and have never had a single issue
Such a nice truck to have such a hard time
As for tow/haul mode, I run around with it on at all times, the shift points are way better, holds gears longer to let the engine work, and it locks the torque converter in 2nd gear instead of at 55mph which takes a lot of heat and out of the converter and reduces wear. And in my case, with having 37’s and stock gears (4.56’s are on the way) it makes a world of difference holding lower gears longer; 6th gear is so overdriven with 3.73’s snd 37’s that it’s unusable. So it actually helps my fuel economy because the engine is up in its power band and holding 12 pounds of boost, so the engine load is 20-30% doing 80 in 5th instead of 40-60% in 6th
Without tow/haul on. Converter locks in 4th
Yup ur exactly correct
CONGRATS JERRY! BUT MAKE SURE YOU COMPLETELY TEAR IT DOWN AND MAKE SURE THERES NO RUST BECAUSE IT DID COME FROM MICHIGAN! ALSO MAKE SURE THERES NO MECHANICAL ISSUES WITH IT BECAUSE AFTER WATCHING THIS VIDEO ILL BE CONCERNED!
The engine wasn't the issue. It's the emissions BS that caused this
Funny how you pulled over in west branch, my grandparents live there and I live about 15 minutes from there.
I would have unplugged the chip you installed on top of the ecu and put it back to complete stock. Not knocking any aftermarket parts but I’d leave well enough alone. My work has 2 duramax trucks and both have cost us close to $80k in 4 months in fuel related repairs. Anyone can guess what failed.
Did you ever let trucks finish regenerating? No, that’s why you keep supporting dealers
@@repairvehicle that's true, my coworker never let's his powerstroke regen and it's a grocery getter and only runs around town stop n go..then it goes to the dealership for a week. 🤦♂️
@@MrStaybrown , stop and go kill’s diesel vehicles. Gas is way better option in stop and go
@@repairvehicle yes sir, I can't convince him otherwise.
@@repairvehicle hybrids like stop n go. Never heard diesels or gas not like stop n go, makes no difference to the engine. Wives myth
My prayers are coming out to you and your brother be safe and good luck!
If you need a truck to get you home let us know! If you're still stuck in CO, I'm right up the road. You can take my Cummins. Ill be in MN next week to pick it up!
I drove a Dodge Cummins six speed for 15 years. Just ordered a 2023 GMC with a 6.6L gas 6 auto. Have three tractors and a Cat excavator..... no DEF on anything.
I’ve been thinking about buying a new truck lately but couldn’t pull the trigger. This video just answered all my questions. I’ll keep my old 08 Silverado and just keep upgrading her.
Keep her
Ya I’ve got an 09. Think we’ll just keep her haha
Damn dude. I’m sorry this happened. Looking forward to the next vid. These types of things (albeit unfortunate) are very educational
I never seen this channel before and this is the first video I seen, live a hr west from the Colorado sign you stopped at in a little area called Ft. Duchesne. I’m sure you will remember the trip for a long time and I’m glad you got home safe. Also the giveaway was awesome and congratulations to the lucky winner.
I have a 2017 Ram 3500 Cummins with the Edge Juice. I live in Colorado and we travel on I-70 up and down the mountains. With my Cummins it will sometimes defuel me and the torque management will kick in when I am hauling our 16k lb fifth wheel toy hauler. It only happens every now and then when I am on level 3 or higher. Yes, I only use level 4,5, or 6 for very short bursts. Then again that is even a bad idea. But hey it’s my truck.
Them l5p must be bad for emission issues my co worker has a 17 duramax that is having a lot of the similar problems. It's just so annoying that the factory spends 1000s on putting on those parts so we have to spend 1000s to get rid of them so we can actually go somewhere without worrying that were not gonna get there.🤯
You are exactly correct
This almost smells like a fuel rail issue. They have a big problem with the pass side rail and connector having issues. If you watch your rail pressures. Fuel rail pressure 1+2 should be near thier desired. Any deviation by more than a couple hundred psi.. there's an issue. Also they have injector and injector connector issues. Also the fact you threw a mass air flow code makes me think you might have an issue there or you have a boost leak somewhere. The other big issue they have issue the def injector getting clogged and causing regens to be a massive pita. Im a gm tech by trade. If you want to work with me directly. Hit me up.
I may be wrong but I’m pretty sure Tow/haul doesn’t result in more torque. Its purpose is to increase line pressure in the transmission and adjust shifting to reduce friction and heat in the transmission while towing.
What a bummer. Amazing you made it out west much less heading home.
It's a little hard giving this video a thumbs up considering how it ended. That sucks!
Delete it but, do NOT put it on your channel.
Second that motion. Don’t put it out there, nobody knows.
They can’t really do much to you at all for a delete unless you have DOT numbers multiple CZcamsrs have gotten away with it
I agree
Need to know. They don't need to know.
Truck: continue driving to regen
Pulls over twice.
Soot level 150g: adds fuel to already clogged dpf
Sounds like earl might have to do some work on the l5p if you know what I mean.
Have you replaced your DPF? I think that could be a major issue since it is emissions compliant and it now has 100,000 miles on it. (This is based off of what I learned in my Automotive class that I took in high school. We didn't go over much because they don't deal with them)
Dpf is good for at least 500k miles or more
I doubt it. Dpf rarely go bad on these trucks. I've done 2. And those were under warranty with less than 10k miles on them.
Definitely scaring me off from going to a diesel.
This is at extremely high elevation, and at the IKE gaunlet. 95% of people are not putting the truck at these extremes.
Hey it's good shit you're able to give the trucks away. It ties the channel together nicely.
I've heard of edge monitors having bad connections and causing trucks to do wonky things. Try unplugging it
And that’s why we delete
Say your adding windmills to the engine, and replacing the drivetrain with child labor lithium/Ukraine biden batteries. Youll prolly get a nobel peace prize.
Yey man, that “Podunk town” West Branch, IA is the birthplace of Herbert Hoover, and I happen to live 3 miles from there.😀
Wow no kidding small world
I’ve heard leaving it in tow haul can actually make it harder for the truck to regen
It’s your tune, it keeps truck running reach and generating more soot. Tune is a death to the engine. Manufacturers spend millions on testing making sure everything works fine. Tuning software companies spend no money on testing, you just get unreliable power and problems later.
With factory software truck is happy and regeneration happens automatically on highway driving specially with load.
thats why i leave my lly alone 05, 200k and going strong. you do not need all that horsepower nor torque u still cant haul more than the manufacture says. why do that to ur truck, all that money for something you dont need in the first place.
Until you're the one on the side of the highway with a trailer, in rush hour stuck in limp mode lol. Been there done that.
@@MRW21783 well not me i have the lly, but i work for a local gov and our fleet is going back to gas engines due to the regen bs on all the diesels.. who ever the idiots at the epa were that thought emergency vehicles would be fine with the regen are truly ignorant college dummies. hope im not in the back of an ambulance when it goes into limp mode for regen what a bunch of idiots. im keeping my lly no issues
@Levi Doherty i do think thats the issue as well. im going to keep my ole 05 love the truck
Thanks Obama! Pos unnecessary equipment ruins another one
If I were to make it in time I would’ve definitely let you take my truck and tow yours home with it if you needed it! That was a long trip for you to deliver a GIVEAWAY TRUCK! You truly are a great man brother!
After two duramax diesels ,nothing but nox sensors,def fluid heaters ,$ 13k cp4 pump ,transmission sensors… I’m going back to a gas rig !
