Transfer pump failed on the 2003 CTD, so the dealer installed the in tank transfer pump under warrenty. On the invoice is showed an "Authorized Software UPD". I have crawled all over under the hood and the only tag I can see is one that says the fuel system has been modified. This is the first time they have done anything but change the fluids in my truck since Oct. 2003 when they sprayed a liner in the bed. There is an item code on the invoice, 4669020, probably the label.
Just curious about if they really changed the programming or if the description on the invoice is bogus. Any ideas?
