Freightliner cascadia DD15 def awning install for 4364 18 nox conversion efficiency low code. 

Sorry to hear that bad news. You always want to trust your techs. My answer is to always find tech or shop you trust to do all your work. Can’t trust just anyone these days.

Awning is only for stopping the slobber of def when exhaust flows past it which in turn causes the low nox code. A onebox price compared to a awning install is about 9k off from each other. I think you may of had a string of bad luck with yours. Or maybe to many miles on your box. But I would never jump to selling a box as majority of the time not needed. It’s all about having someone that knows how to read log files correctly.

@@bustedknucklebydieseldr3228 the mechanics told me that very thing. I ended up wasting 9k replacing harnesses, nox sensors, the list is too long to put here. And ended up needing a onebox after all that expense. I even had the DOC cleaned with an ultrasound. Each mechanic would tell me a different story. It’s the clients choice I guess. I wish I would have replaced mine at the very beginning. You can’t win, even after replacing everything, I’m still in the shop for ACM, then ECM, hunting it down with the parts shortage. The best thing to do is drive the mfer off a cliff.

Did it help?

@@dkz2802 yes please

Appreciate the positive feedback good sir

With your crazy weather on the east coast I’m glad I’m on the west side. Working in the rain what a pain. That awning install definitely helps but isn’t a 100% guarantee fix. There’s usually an underline issue like a sensor screwing up or poor metals in the one box deteriorating. But only diag with a computer will tell us. Dealers should have a lot of info on this but than again it all comes down to the tech working on it.

@@bustedknucklebydieseldr3228 haha! Yea between that and snow. I don’t blame u. But yea Man U detailed with it. I don’t think they took the time like what I’m seeing.

Def crystals build up causing blockage. This somehow prevents that

Thanks for reaching out. Yes this would be a great time to do the filters since one is going to be out anyway. 500k miles they should be getting close to plugged up anyway. Harness is rarely the issue unless you had circuit failed codes. Otherwise usually a sensor issue. Hope that helps

If your really looking to save some $$$ that’s one way to do it. My last one was two coat hangers , one soda can, and 4 straws. Check Eng light is on, not sure why though.

Haha for sure man. Do the delete and get a good tuner. That would be the ultimate fix. Just don’t get caught. No matter what there will be always be more codes from the aftertreatment system.

As of now I do not, But maybe that'll change in the near future. Appreciate your support with checking out these vids..

This is only standard on trucks 2022 and up. Keep in mind this is t a definitive fix for nox codes but it does help out a known problem Detroit has

The awning definitely helps but doesn’t always cure the issue. If you have over 500k on that truck than your one box may not be able to clean well enough causing this code to come active. There’s a lot of test la that need to be done before making that $10k call.

That’s great man. Atleast you were able to see the problem of def build up. Now just check the def doser on how much it produces and make sure it’s good. If it’s to much than you’ll run into the same issue.

Great question. I don’t have my own shop as of yet or one I can mention on here. But hopefully that’ll change one of these days.

If you don’t mind dealership rates I’m located at chandler freightliner in Az.

Thanks for reaching out man. I wouldn’t think it’s the vgt having an issue unless it’s throwing a code for that or having boost issues. I would focus on the onebox and all the sensors on it. I do find that some tests need to be done a few times especially the def quantity test to see if results are accurate. If you trust this tech than I’d listen but if your skeptical than find someone else. A second opinion won’t hurt

@@bustedknucklebydieseldr3228 thanks you for your help men ill look a second opinion thanks..

At my local dealer. But you can also find them online for much cheaper.

Thank you for watching and reaching out. Also if you haven’t subscribed yet please do. That awning is readily available at any dealer so it’s strange you haven’t been able to find one. I wish I had my own shop but not just yet. Maybe when I build that subscriber list I can afford one. Remember that shield isn’t the magic fix but it definitely will help things. There very well could be a sensor drifting or onebox failing.

For this Cust, yes it fixed the code.

Thanks for watching man Don’t forget pass the videos on to all your peeps. That code is diabolical. Plagued Detroit and Cummins for many years. There are so many things it could be. Biased sensor, def build up in one box system , old one and deteriorated metals,bad def,heavy load uphill and ghost code. Sadly that code can drive us crazy to find. More common issue is a sensor drifting and def build up in scr catalyst.

How do I get that part I do it myself

@@andrewilliams9149 sorry man there’s no telling what part he’s failed without doing diag and I would never recommend just wasting money and throwing parts at it. I’m all about saving the cust money and keeping the truck on the road

I get this code Everytime when go up hill and comes to 55 mph after 30 min drive on normal road code get clear itself.can you help me?

@@harvindersingh3828 thanks for reaching out. With this particular code as you can see in the video theres extensive t/s that needs to be done. There is so many things that code cause this issue. And the reason the cel turns off is it recognized an issue and that issue subsided for the allowed time. So there is an issue , it would just need to go to a tech/shop you trust to diag this right. Hope this helps and be safe out there

The 19s run a little bit better and you most likely won’t need it installed but there is still that slight chance when you get this reoccurring code.

Good question. So the new generation comes with an awning built in so there quite a few other things that would cause this. Such as a def doser not producing the correct amount of def, any of the sensors drifting, intake or exh leaks. Really a tech would just have to start from the beginning and go through a long check list. Luckily it should be under warranty being a 19.

Got it. Thanks. I'll have to get it into the shop.

I do not have my own shop as of now or one I could mention on here. But hopefully one of these days that’ll be changing

Yes sir I’m out in phx. Don’t have my own shop yet though.

@@bustedknucklebydieseldr3228 I'm in Phoenix AZ on the regular how to get intouch with you ... I've watch alot of your videos and I can say you know the DD15...

@@blackthunderbolt3699 thanks for the feedback man. I don’t have my own shop as of yet but hopefully that’ll change if this channel can grow big.

I’m out in Az

Unfortunately I do not have a shop of my own or one I can mention on here. But hopefully one day soon that’ll change. Thank you for your support.

Thanks for reaching out. Figure about 8 hrs labor of what the door rate is and maybe 300 in parts. Nothing to crazy.

I do not but part # should of been provided.

I like where your going with this.
