Trouble seems to follow us...
This time it is vehicle problems. I am sure I am not the first but I must say, I absolutely HATE the new DEF exhaust systems they have on newer trucks these days. 2nd truck, same problem...only this ...

Seems like a lot of people confuse DEF and DPF. DEF is the fluid that is used to reduce NOX. DPF is the diesel particulate filter in the exhaust system. Its purpose is to trap soot. While both are emissions equipment, they are separate systems.
