The DPF system does not make soot and clog up on its own ... it collects it. -- Something is wrong with the engine if you are getting DPF issues.

When is the last time you replaced the IMAP and other engine sensors?... cleaned the egr system out?

How much oil does the engine consume?

Any coolant losses?

-- Also, what is the regen history? -- Truck usually does not get into that much of a dire need situation unless it has been neglected and no one has been keeping after the regen system, ensuring the average in the graph is staying less than 3.0 inhg.


Start by hooking up Insite and see what the problem is. Every person who owns a truck with an ISX should also own a laptop, an adapter, and a copy of Insite... simply to prevent a towing bill, or getting ripped off and taken advantage of, and also to keep after the regen history and to help keep you off the side of the roads every time it hiccups.

Thank you Rawze for your input
