Dpf won't clean with regen

Had same problem on my 2014 volvo d13 it was a rubbed wire by the air blow off valve.. i know Volvo said they r replacing this line now... its supposedly an up grade to def system... many trucks r getting this problem now.. new line has like hockey tabe loom around it now...air purge to def tank is where they found my rubbed wires, thank god was warrentied still.

 

Hi, can you help me please, I had the same problem yesterday after driving on rain. Did you find the problem, how did you fixed it?

 

The j / pilot has had claims in past for poor def supposed to be 31% or higher. They sell Dec checkers at most auto parts stores like the little anti freeze testers. Some drivers drain & refill with good bottle stuff & lights go away.

 

Thank you !!!! I drained all def and I refilled with bottle def. I did regen again and the codes and lights about regen system went away. I did my last fuel in PA I-80 exit 29 TA, and after aprox 100 miles, all this happened

 

Ya...sometimes you see ole boys buying "expensive arse jugs of DEF...There you go...Watery Def...it "Happens".

 

Yes. Definitely you need to check a wiring harness that goes to a DEF pump. Last time I found two wires corroded and broke right off
