Review on 🔥 Dorman 904-392 Diesel Exhaust Heater by Carlos Deuschle

the part appeared to be of good quality and set the code for the defective heater. However, the next day a new code was launched and cleared several times due to low DEF pressure. The code kept coming, so I ordered a new DEF pump and installed it. The code kept coming, I had to pick up my truck so I was taking it apart and trying to blow it through the intake manifold when I found the filter at the bottom of the heater pan was completely clogged with plastic liner. I drilled out the plastic and reinstalled it and it's been working ever since. BAD quality control.
