Incorrect Def

[oldwhite1957]

added some def blue to my 2015 1500 ecodiesel after about 30 km dash reading incorrect def now reading will shut down in in 310 km see dealer any body with this problem

There is no incorrect DEF. Def is DEF. That said, DEF comes at 32.5-33% urea and can deteriorate and throw that message when it gets to 22%. It sounds like the DEF you used was old and below 22% Or as some have posted, there are reports of people buying DEF at Walmart, using it, refilling the container with water and returning it to the store for a refund. Or, maybe your sensor has gone bad. Or ???

You can't help but laugh at that. People are crazy.

John 2017 and earlier Have a common sensor ,it's only capable of detecting Urea/Nitrogen. So you can run ratio's to 5% Urea/Nitrogen to 95% Dist/DIO water. I ran My 2015, down to that level its entire life I owned My 2015 4.25 Years. 2018+ have quality sensor so 22%+ is needed... 1000s of DEF Truck owners (IMO) have now caught on to this and run much lower ratio's, My 2013 6.7 Cummins has run those level's its entire 10 Years of life and still going strong without 1 issue.. other than I kept dumping Distilled Water in the tank for over 12 Months, When I check the Ratio it was 98% Water / 2% Urea/Nitrogen, it triggered a rationale code, I added 2 Gallons of DEF deleted the code and all's been well for over 13 months.

TC.
You are the one who put me onto mixing DEF with distilled. I use your 1 gal distilled to 2.5 gal DEF for a 26% ratio, been using it ever since I discovered my 2016 Eco will alert at 22%. I run the same on my 2020 3500 HO, don't know i5t's alert percentage

OK... just say close to 22%....... Did you get the self destruct code or rationale code?

Self destruct

 

[TC Diesel]

It's a hyperbole, Some promote that using any other ratio than 33/67 the DEF system will self-destruct or the environment will cease to allow life to co-exist.
