I have a problem with the def

Do not drill holes in your dpf. Your asking for problems. Check engine lights, de rate, down time, Ect.

 

You've noticed that's year old post?
And as far as def filters go, I've just got one today from a dealer for less than 40 bucks

 

I have driven three different trucks, within a year, that begins with the same problem. The Doser injector went bad, cost range from $600 to $900. System is a fault and owners are paying too much for it.
