Similar situations happen all the time. The problem is that these repair shops, and what is even worse, the dealerships, they charge crazy money per hour for service, but they don’t have knowledgeable and competent mechanics! For very few exceptions! That’s why they change the parts that not need to be change. And the worst part of everything is that they are not held accountable or responsible for wasting your time and money. And it’s happening everywhere you go. It’s pretty much like you see a doctor for headache and he cuts your leg off to fix your headache. It’s terrible. I think that if mechanic change the good part or didn’t fix the problem, you shouldn’t be charged at all. It doesn’t matter if he change half of a truck with new parts, if the initial problem was not fixed! That’s supposed to be on the shop, not the customer! If you are not knowledgeable mechanic, it’s a shop and mechanic problem, it’s not the driver problem! They supposed to be held liable and pay for their incompetence!
so im a diesel mechanic and i fix aftertreatment systems. there hasn't been one i could not diagnose yet. let me tell you yes they are hard to diagnose. but 8 times out of ten youre going to have at least 2 to 3 issues with your system. and almost always the first issue that shows up is going to be the effect and not the cause. now if they fail to miss harness or electrical problems then thats poor diagnostics. but sometimes it can take 2 trys to get it right. in your case it was obviously a failure in diagnostics. but i will tell you 99 percent of the time the def header is usually the problem with this issue. ive only seen one time where it was the harness and never had to replace an acm.
These d e f systems are the worst thing ever I'm dealing with the exact same problem I have a Peterbilt and this thing has been even Peterbilt can't solve the problem and they made the truck
I'm going through the exact same thing. 2 mechanics so far and out $3500. After paying to get my filters cleaned, and 80 miles later I still had the same code they claimed I need to give them 3200 to get new filters bc they're bad now. 2nd shop just cleared ecm and did a regen for $500, 10miles later same code. Brought it home, replacing all my dpf sensors myself, and a diag tool. In the process of still replacing sensors for a fraction of the price
Just had this issue on my 2014 Mack CXU. After being stuck at a truck stop for two days the techs there couldn't figure it out after throwing all kinds of parts at it, Exhaust temp sensor, two def wire harnesses. I brough it to Mack they hooked up to it and had it diagnosed in an hr. Bad def doser, and the aftermarket temp sensor the clowns installed wasn't communicating with the trucks computer, so had to be replaced again.
Bruh.... that sucks. I clicked on your video because I am having the same code/derate warning popping up. This is not reassuring but thanks for the tip
If you take off the abs fuse from the fuses box you good to go that set you need to watch more you tuve video my friend you can save thousands of dls by watching this videos do not call shops people just find a video about you problem in it’s for free just get the abs fuses out in you engine would be good to bo
you even don't want show the most important part of video in order some one else truck drivers like u to learn and not to foul on mechanic scamm so first start to ur self good deeds
That sucks, man. I have constant def/dpf issues with my paccar. I'm about ready to drive it off a cliff. The DEF nonsense is the worst thing ever inflicted on the trucking industry. It's basically leftist policies implemented into your truck to keep it from doing its job of going down the road. I have spent $4200 this year so far on this crap. Two Peterbilt shops so far, and going back in tomorrow. If truck drivers were as bad at their jobs as diesel mechanics are at theirs, every load would be late or never make it at all.
@@TruckingUnfiltered I Know everything about this system. They made it so complicated that the average trucker will never figure out what the problem is. I’m 100 percent sure they programmed certain electrical and electronic parts to break down at a certain point and also the connectors and wiring is designed so the water and heat can easily destroy it and you can keep going back to them for repairs and keep giving them money
What a horrible story im sitting here feeling so sorry. Ive been through all if that myself. Its so fuxking depressing. Since then i bought an older truck with only egr, no def or scr. Ive learned as much as i can about keeping the emission system running so im good now, but yeah i spent 10s of thousands on that crap with shit mechanics.
@@trucker1one I dont know how much worth your junk truck. Spending 10k for def matter? I will just delete it for 1-2k and run save money for future equipment.
So you're just saying what everyone knowsthat most mechanics don't understand what they're doing and they just think that it's all about R&R, useless info
If you clame you are a mecanic and start changing parts only by quessing, you are not a mecanic, especial when you dont asume the parts what suld not be changet in the first place 🤔
Hello brother I hope this message finds you well. I’m from Houston and I got the same problem and as you said all the mechanics are guessing what is the issue. So can you please help me out to fix this problem? Can you please send me the phone number of the mechanic who fixed your truck . Thank and I appreciate your help.
