Volvo DPF / SCR problems

Here you go people. This is how a person who inderstands the system can figure out what could be wrong with the system and on what you need to focus on next. Off course those values could be affected by many things prior to the ATS system like injectors,turbo,egr cooler, diesel and def quality etc. But without performing service regen and looking at all the things that @nasriza described you will 100% fail on diagnosing a truck with an issue.
So thank you @nasriza for the great post.

 

Here is some help for you and others

Here is couple of things i want to point out all you guys can think of and may be changing.
The 2 most common things i found that affect the DPF and SCR are bad diesel and bad DEF. I'm sure that many of you can relate to:
"SCR Performance Low. Check SCR system or engine will derate soon"
Well that is most likely caused by one of the 2 things i pointed out and addressing those could highly benefit you.
1. DIESEL - if you are using diesel that is 20% Bio blend you will have lower combustion temperate and will affect DPF and SCR efficiency. Do not use any diesel from Pilot/Flying J as there is only 20% blend. We've did a lot of trying and research and found that Loves, Shell and Exxonn have blend of 5 to 10% percent and since we use those issues related to diesel quality are 0 !!!
What you want to look for is the color of diesel prior to filling up your tanks. Yellow or Brownish color are NOT GOOD! You want to see greenish/ blueish color or no color at all. Just simply drop some fuel on the ground and you can determine that .

2.DEF - the Diesel Exhaust Fluid is a mixture of 33.5% urea and 66.5% purified water. If that mixture is not right - lets say you have more water content than it will not turn into amonia once sprayed into the exhaust stream thus the chemical reaction when in touch with the paladium coating in the SCR will not going to occur and NoX PPM output will exceed the allowed by EPA
07 , 10 , 13.
And year ago ive did some testing on DEF from the pump and what i found was astonishing. 17 out of 20 had very high water content. Then i tested 2.5 gal jugs and only 2 had it - which were less known brands. We started using Blue Def from Walmart, Mennards etc. And i never had to drain def and clean the def thank. Some extra help here will be a DEF tester about $30 or testing strips about $70.
I hope that help

That your personal choice my man - and it's a good one. If i was you - with limited or no knowlege at all as far as Aftertreatment Systems sphere is I would go ask @nasriza and spend my time with him because he is good......very good. Now that being said - if you are here only here just to right something but not to contribute for people who need help - my advice is to go back to Facebook or Tweeter or something - you could be more valuable there my man.
As TheReal Donald says - you are fake media Lol
