They updated the software and replaced nox sensor. Its very frustrating, they say they have to follow some protocols to do repairs under warranty.

 

Did you read the link I posted?

 

Legally they don’t have to, commercial equipment is buyer beware

 

It's crazy this is the way it works. I just drove the truck 3 hours on the route Houston-Odessa and I got the first check engine light, there is no way the selling dealer did not know about it.

 

I did Sr, and I sent it to the repairing dealer. I am going to ask them if they even look at it.

 

I’ve yet to hear of someone trading a truck in because it was running too well…

 

Unfortunately you’ll have to keep going back until they’ve gone through it a few times before they’ll finally authorize a new one box.

When mine began to act up, I just kept driving it. It would Derate me to 55 mph for a few minutes then clear up . Over time it happened longer and longer. I had a licensed copy of Detroit Diagnostic Link so I was able to do my own forced regents to get the codes to clear.
Eventually it got to where it was happening sever times a day, then I finally took it into the dealer. They only had it twice, then put in new injectors and a one box. Worked good agpfter that.

 

That's exactly what they suggested would happen. I told them that the nox sensor failing is just a symptom of a problem they haven't found yet. This is the second time they've replaced the nox sensor. I also told them that I find it illogical for them to do the same thing, replacing the same part, and expecting different results. But they said that's how the warranty works. I have an OTR device that can do forced regens and clear the codes. I am going to take your route good Sr. I am still going to contact the selling dealer manager and Daimler. It’s been a non pleasant experience since the beginning. How did you get them to replace the injectors?

 

Thanks for your answer. Any more suggestions and tips on how to go about it? I am a neophyte on owning a truck.
