I doubt it will help, but it sure wont hurt lubricating the pump and inside the injectors!

The dealership also said that the actual p0404 code was the code for an error in the pintle valve position for the EGR valve. Said mine was staying open, which I assume is what its doing on everyone elses....

I looked at a LB& Federal Emissions ECM program and it had the EGR tables in there, they were just disabled.

P0404 is for: Exhaust Gas Recirculation (EGR) Open Position Performance

the open position must be the pintle valve being stuck open. Now the question is where is the pintle valve, and how hard to replace, and what is the cost?

Let me know how it goes next Thursday.

This is my first diesel truck (03 2500HD 72k miles) also and these forums are starting to worry me about owning a diesel truck. Do all the mfgs have this many problems with their diesel engines? I just bought my diesel truck about a month ago and maybe i'll be headed back to a gas model soon. It sounds like the diesels might be expensive to keep running. So far i have had problems with the gauge cluster stepper motors(tach and speedometer), low oil pressure, mass air flow sensor. I'll keep reading here so i can learn more and try to avoid some of the major problems.

For the most part, you will hear all the bad stuff here b/c ppl come here to try and find out how to fix their problems..You arent hearing from everyone that isnt having any problems at all....For ALL the diesel owners that are out there, this is a very small % that you see posting up with problems..I wouldnt worry about it too much....
