I recently deleted a dpf on a customers truck, as well as set several code's to:
non emmisions mil off, and still have the light on, these are the reoccuring codes P0401, P2033, P2455, P0546.
i know P0401 is the EGR, the really isnt the problem i can fix that one.
the truck was run for about 10 hours before the others set, its a 8594 truck.
im using v7.5.6 build 139
input would be greatly appreciated.
