start with a thorough EGR tune-up and ensure there are no exhaust leaks etc.

Things like replacing the IMAP sensor, Cleaned out the EGR piping and valve.. replaced the EGR Delta-P and other related sensors?

Anyone bother to clean the Doser Injector tip and inspect it for seepage?

How about mileage, etc?.. what kind of mileage is on those DOC/DPF cans? . When is the last time someone pulled them off and had them baked, de-ashed, and flow-tested?


-- Its called preventative maintenance for a reason. The DPF system does not make soot... it collects it. You must service the engine by doing tune-up work to it in order to keep those exhaust systems happy.
