    E46 Error Code Help Needed

    I have a 2004 325i with m54 engine. Using Carly scanner, I'm getting and engine fault code 0027cc. The cel is on. I cannot seem to find any good information to diagnose the issue. Does anyone have any information on this code? Thanks!

    I would like to be able to help, but I don't understand several of the acronyms being used like DMTL CDKDMTK, ect. From the looks of what I can understand it is pointing towards an Oxygen sensor, bank 1 which is cylinder 1-3.

    What tool are you using to read this code?
