Not sure those #s exist. Look in the tech folder.

P0000 is no code at all or no codes present. Im not sure P0004 is but i bet its something similar.

P0000 is a "pass" or no codes/problems found DTC, so it is odd that you would have it with the P0004.

One could be a key on engine off test, on could be a key on engine on test. Thats where you could pick up the P0004 codes, or depending on the differnt tests done you could also get that code.

I am a little confused about this code P0004. I thought the 6.0L diesel regulated fuel pressure and not fuel volume. The code P0004 is a generic code for OBD II and is not used by all manufactures. So far the only maker that I have found that uses that code is GM for their fuel systems. I could not find that code in my 2005 service documentation for the 6.0L. It does means what PowerStrokeHD has posted I am just not sure if it applies to the 6.0L. Could be your x3 is putting out a wrong or false code.
