DEF fluid in heavy equipment !!

[BRICKNICK]

It's horrible Mario I deal with it daily, and our brand new 950 wheel loader has had the cat tech at our shop at least 5 times in the first year for the dosing nozzle screen of the system getting clogged with debris and the loader will not regen and it derates power and etc..... Our new peterbilts showed up with check engine lights and still till this day the dealer can't get them to stay off. Everything we have with regen systems are horrible. Makes me not wanna be a mechanic since they allow pencil pushing politicians and legislatures decide how our equipment "should" be. They know nothing and mechanically understand less then nothing. When the peterbilt dealer held a local Q&A for all the dissatisfied customers and they're basic jist of the meeting to us customers was "bare with us, we are trying to get it right"....u know this are horribly wrong.
